rellla has joined #linux-sunxi
<oliv3r> resistencio maybe your missing a dependacy? maybe your 3G modem doesn't have ARM drivers?
<jelly-home> maybe whoever built the kernel forgot to define CONFIG_USB_SERIAL_OPTION
<jelly-home> there's more than one kernel build out there with a really meager choice of drivers built
<oliv3r> yeah but the default config for sunxi is pretty reasonable
<oliv3r> also, 'make linux-config' is the next possible step I suppose :)
<oliv3r> *back to documenting on the wiki :S*
rz2k has joined #linux-sunxi
* rellla wonders if oliv3r dreamed about the wiki ...
<oliv3r> heh, i hate editing the wiki :S
<oliv3r> so it's nightmares if anything
n01 has joined #linux-sunxi
<oliv3r> n01: !
<oliv3r> n01 md 0x01c20c90 1 says that WDT_KEY = 0; so is the default really 'something? or does it need to be turned on first?
<n01> 'morning oliv3r :)
<oliv3r> also, good morning :p
<n01> TMR_WDT_CTRL is supposed to be 0
<n01> "Restarts the watchdog timer" so if you write 1 the wdt is simply restarted
<n01> but maybe I did not understood your question
<n01> *understand
<oliv3r> WDT_KEY
<oliv3r> TMR_WDT_KEY 1:12 Read/Write 0x0a57
<oliv3r> that one :)
<n01> ooooohh
<oliv3r> i do a md in u-boot, but it reads 0x00
<oliv3r> is it write only?
<n01> yep AFAIK the key is used only when you reset the wdt (write)
<oliv3r> (assuming the key is actually needed to arm the timer)
<oliv3r> ok so 'reading' will always read as 0, writing it is required to arm the timer
<oliv3r> or, disarm rather (reset)
<oliv3r> so you'd do writel(reg, WDT_RESET | WDT_KEY);
<n01> yes, even though mripard said that the key could be not really used on A10
<n01> WDT_KEY is shifted by 1
e-ndy has quit [Remote host closed the connection]
<oliv3r> yeah, should be relativly easy to test then, specially with more hardware to test this on (a20!)
<n01> yup
<oliv3r> writel(reg, WDT_RESET | WDT_KEY << 1);
<n01> I hope in the giveaway :D
mturquette has quit [Quit: leaving]
<oliv3r> :p
<n01> yes but: (1) check for the precedence between | and << and (2) since you don't know what is in bits 13:31 it is better to read the reg content value before modifying it
<oliv3r> it was an example :p
eebrah|away is now known as eebrah
<oliv3r> i agree, a weak one :p
<oliv3r> it was basically a nerdy way to say, so you supply the key simultaniously to restarting the WDT or it won't work.
<oliv3r> and now you made me type it all out anyway :p
<n01> :D
<oliv3r> there, tried to wiki-fy it
<oliv3r> if you could double check it for obvious mistakes, that'd be swell
<n01> no prob
<oliv3r> then again, i made a typo, sec

<oliv3r> n01: did you manage to get me a working kernel? :)
<n01> ups ... you have to remind me after 7pm when I go home
_BJFreeman has joined #linux-sunxi
<oliv3r> heh
<oliv3r> i was busy writing wiki's anyway till 12
<oliv3r> :p
<oliv3r> just thought of it now
_BJFreeman is now known as BJfreeman
<n01> oliv3r: anyway AFAIR it should be enough to use multi_v7_defconfig, enabling sun4i-a10-cubieboard.dts and eventually to use initramfs
<oliv3r> yeah, but i get no kernel output :( so it may run, but i don't see
<oliv3r> i used setenv bootargs earlyprintk console=ttyS0,115200
<mripard> oliv3r: do you have enabled earlyprintk and debug_ll ?
<oliv3r> i use default multi_config
<n01> it is the dirty repo but at least it works for me
<n01> I'm rewriting it for submission but I didn't uploaded it yet
<mripard> oliv3r: then, enable it, boot it, and see if it's actually booting or not.
<mripard> because you might have the correct console and so on
von_fritz has joined #linux-sunxi
<mripard> but it might crash before you even have an uart driver loaded
<mripard> and thus, you don't see it.
<n01> it is dirty and old but it worked for me
<oliv3r> mripard: hmm, i thought earlyprintk and debug_ll where enabled; let me double check that first
<n01> otherwise wait until evening :)
<oliv3r> n01: those configs won't guarantee that it works though
<oliv3r> simply because something else might be wrong, compiler, settings, u-boot etc
<n01> yes I know, but at home I have a fully working config for buildroot using mainline with u-boot etc...
<oliv3r> EARLY_PRINTK [=n]
<oliv3r> ouch! :(
<n01> LOL
<n01> i told you yesterday also
<mripard> oliv3r: enabled for what uart driver? at what base address ? :)
<mripard> you can't just enable it on a multiplatform kernel
<oliv3r> mripard: ok, so how do I enable it for our platform :(
<oliv3r> n01: assumption, mother, etc. I only checked the setenv stuff obviously, i assumed our multi_v7 would enable all that
<mripard> well, menuconfig, Kernel Hacking, CONFIG_DEBUG_LL, etc.
<mripard> as usual
<oliv3r> 'as usual' I never had to enable it :D
<mripard> come on, you never had to configure a kernel?
<oliv3r> but i should figure it out :)
<tavishb> anyone have a working manifest to compile android for A10? (for marsboard)
<oliv3r> not the 'what uart, what base address' bit! :p
<oliv3r> i never really looked at the kernel hacking section!
<mripard> ... Look at the debug_ll option
<mripard> you'll see
<oliv3r> found it
<oliv3r> i looked over the list FOUR times :S
<oliv3r> but saw it now
<oliv3r> dislectia ftw
<oliv3r> yeah baby yeah
e-ndy has quit [Remote host closed the connection]
<n01> mripard: "I'd prefer to see the bits values just behind the register they belong to." WDT_CTRL and WDT_MODE _are_ the registers they belong to
<mripard> no
<mripard> I meant having
<mripard> CTRL_REG
<n01> yeah but WDT_CTRL == CTRL_REG
<n01> just naming convention
<mripard> aaaah
<n01> :)
<mripard> let me finish :)
<mripard> so I said
<mripard> CTRL_REG
<mripard> CTRL_RESTART
<n01> :D anyway I'll send a v2 for your other concerns, no prob
<mripard> MODE_REG
<oliv3r> i have to re-read your naming convention again in a mail you wrote a while ago
<mripard> MODE_RST_EN
e-ndy has joined #linux-sunxi
<mripard> so that you have a register definition, and the bits associated to it, just below
<n01> ok got it
<hno> mnemoc, pushed out a raw disassembly of the AR100 code to
<oliv3r> hno: those strings are at the very least interesting
<oliv3r> 'ar100 notify ac327 wake up event detect', ac327 is the internal name for a31?
<n01> mripard: can I leave the names I used?
<oliv3r> or for the CPU core or something?
<mripard> n01: yeah, definitely
<n01> good
<oliv3r> well if better names are possible ... :p
<n01> I'll name one register OLIVER_REG
<oliv3r> :p
<hno> oliv3r, ac327 seems to be the code name of the ARM part of the SoC. A31 is the marketing name for the complete SoC. aw1633 seems to be the code name of the SoC.
<oliv3r> ah, i see
<hno> A10 is AW1623, A13 AW1625
<oliv3r> we don't know about A20 yet do we?
<hno> aw165x I think.
<hno> config ARCH_SUN6I
<hno> bool "Allwinner Ltd. AW163x family"
<hno> bool "Allwinner Ltd. AW165x family"
<hno> config ARCH_SUN7I
<oliv3r> ah yes
<mnemoc> hno: can this little endian openrisc be worked out with standard tools?
<oliv3r> mripard: yay! i can get output, though fails at booting
<mripard> what's the error?
<hno> mnemoc, seems it's not actually little-endian. But it's memory bus is byte swapped so it looks little-endian from the little-endian ARM side.
<oliv3r> so a little endian hack
<n01> oliv3r: did you load the dtb?
<mripard> oliv3r: how do you load it?
<mnemoc> hno: uh
<oliv3r> sun4i#setenv bootargs earlyprintk console=ttyS0,115200
<mripard> you seem to use the old-style kernel loading, with the machine IDs and so on
<oliv3r> sun4i#fatload mmc 0 0x48000000 uImage
<oliv3r> sun4i#fatload mmc 0 0x40000000 cubie.dtb
<oliv3r> sun4i#bootm 0x48000000 - 0x4000000
<hno> yes. Evident from the byte ordering of strings in the binary. 32107654BA98FEDC
<mripard> you're missing on 0
<mripard> *one
<n01> :D
<oliv3r> bah
<oliv3r> i hate stupid mistakes :(
<oliv3r> makes me look stupid :)
<mripard> i'm not saying it will solve your problem, but it won't help :)
<hno> most mistakes are stupid.
<oliv3r> you sure?
<oliv3r> sun4i#bootm 0x48000000 - 0x40000000
<oliv3r> 0's match now, same error
<mripard> yes, and the most obvious one are the most trickier to find :)
<n01> oliv3r: have you enabled dtb in kernel conf?
<oliv3r> yeah, but i'm really bad with numbers, if they are all the same
<oliv3r> n01: of ... course, let me tripple chekc though
<mripard> oliv3r: and in u-boot ?
<oliv3r> ohh, that's why turls kernel didn't work
<oliv3r> no, not in u-boot
<oliv3r> unless it's enabled by default
<n01> but sunxi-uboot already has it
<hno> are you sure 0x40000000 is a good address for the DTB? Thats the absolute start of DRAM.
<oliv3r> how do I tell the kernel to use dtb, i only see options to append it OR to remove legacy mode, not how to enable it
<mripard> oliv3r: the kernel is fine.
<hno> I would have kernel ax 0x44000000, dtb at 0x48000000 or so.
<oliv3r> hno: i probably better use 0x430.. script.bin gets loaded there
<oliv3r> i used 0x4000 from some doc
<n01> hno: I use it and it works for me
<oliv3r> or no, turl used those? and n01? or both
<oliv3r> ah see, i blame n01
<hno> I would avoid 0x43000000 for that exact reason. Is handled quite special if you load a script.bin enabled kernel.
<n01> :D
<mripard> n01: not for everyboard iirc
<oliv3r> i'll use 0x440 then
<mripard> n01: I remember having to enable it for some board I have
<oliv3r> what do I need to change to u-boot to enable dtb
<hno> oliv3r, keep in mind that kernel gets relocated to 0x40008000
gzamboni_ has quit [Ping timeout: 264 seconds]
<n01> I'm assuming he is using cubieboard
<hno> so 0x40008000 + size of uncompressed kernel (including bss) needs to be free.
<oliv3r> btw, 0x440 gives same error :p
<oliv3r> cubieboard indeed :)
<oliv3r> so, u-boot, does it need any build option to enable dtb?
<hno> oliv3r, yes, but is enabled by default (or should be)
<mripard> yes, it was in the link I pasted you the other day
n01 has quit [Read error: Connection reset by peer]
<hno> mripard, what link?
<mripard> some link I pasted to oliv3r about how to do device tree booting
<mripard> from Linaro's wiki
<oliv3r> oh yeah
<oliv3r> i have that open somewhere
<oliv3r> copy paste fail

<mripard> hmmmm, right, sorry.
<oliv3r> so is this error u-boots fault, or the kernels fault?
<mripard> hno: it looks to be enabled in u-boot in the sunxi-current branch
<mripard> not in the sunxi one
<oliv3r> i'll switch to sunxi-current
gzamboni has joined #linux-sunxi
vicenteH` is now known as vicenteH
<n01> yep, I use sunxi-current at home
<oliv3r> Your branch is behind 'origin/sunxi-current' by 719 commits, and can be fast-forwarded.
<oliv3r> ouch
<oliv3r> :p
<oliv3r> buulding the whole shebang!
<hno> mripard, quite possible. Really should switch everything over to sunxi-current.
<oliv3r> bah, u-boot errors out on build
<oliv3r> better clean stuff

<oliv3r> i broke my bootloader :( u-boot stops after 'DRAM: 1 GiB'
<Turl> oliv3r: ouch
<Turl> oliv3r: sounds like just spl is working
<oliv3r> spl prints output?
<Turl> yeah the dram size as far as I recall
<oliv3r> and how do I fix it? :D
<oliv3r> hmm, i may see it
<oliv3r> lets boot it
<oliv3r> nope, same
<oliv3r> i thought that maybe i had the seek wrong on the DD job, but nope, doesn't work :(
<oliv3r> let me print o utput
<oliv3r> i think u-b oot does 'something', but doens't get far enough
<oliv3r> SPL and uboot both start though
<oliv3r> SPL prints dram, but so does u-boot; so it's not that
<oliv3r> i have my u-boot and spl here:
<mripard> techn_: ping?
Guest51602 is now known as LoCoZeNoz_ZUE
<Turl> oliv3r: btw, I've pushed sunxi-next to linux-sunxi and verified it to boot
<oliv3r> sunxi-next is the 3.9 branch; right?
<oliv3r> well right now, my u-boot refuses to work :( so I think my kernel works, but uboot is broken :(
<n01> oliv3r: do you use cubieboard_defconfig on sunxi-current?
<oliv3r> i buildusing the BSP, so I do assume so yes
<n01> why? just compile from sources
<oliv3r> UBOOT_CONFIG=cubieboard
<oliv3r> the BSP 'just compiles from sources'
<oliv3r> the whole 'eat your own dog food' thing
<n01> why don't you compile by yourself? :)
<mnemoc> you can edit the file manually if you like
<oliv3r> n01: because that would be stupid :p
<oliv3r> the bsp doesn't do much else, cd u-boot; make
<oliv3r> it just sets up some variables
<n01> not at all ... at least you would have the full control over compilation IMHO
<oliv3r> but what would I wanna control?
<oliv3r> the BSP is just some fluff to ease things
<mnemoc> saves a lot of typing
<mnemoc> but you still in contorl
<n01> ok, neverming
<n01> *d
<oliv3r> anyway, since we recommend it sort of to users, we gotta test it too :)
<oliv3r> n01: have you ever looked at the bsp?
<n01> nope
<oliv3r> u-boot, linux-sunxi are git-submodules
<Turl> oliv3r: 3.10-rcN+ actually
<oliv3r> the 'script' simple is a Makefile
<oliv3r> it's nothing speciall really :)
<oliv3r> not some secret sauce that patches things :)
<oliv3r> n01: one really big advantage is, it seperates the generated output files from the source, so they don't get mixed. anyway, this is what the BSP uses to build u-boot:
<oliv3r> make -C u-boot-sunxi all O=/silo/build/sunxi-bsp/build/cubieboard-u-boot CROSS_COMPILE=arm-pc-linux-gnueabi- -j8
<oliv3r> n01: so I don't really see any reason to replace 'make u-boot' with 'cd u-boot-sunxi; make .....' :p
<mnemoc> the O= is very useful to keep your source tree clean
<oliv3r> ok I lie, when rm -r the build dir; i get:
<oliv3r> mkdir -p /silo/build/sunxi-bsp/build/cubieboard-u-boot
<oliv3r> make -C u-boot-sunxi cubieboard_config O=/silo/build/sunxi-bsp/build/cubieboard-u-boot CROSS_COMPILE=arm-pc-linux-gnueabi- -j8
<Turl> what toolchain is that?
<mnemoc> gentoo?
<oliv3r> yes
<oliv3r> gcc version 4.6.3 (Gentoo 4.6.3 p1.11, pie-0.5.2)
<oliv3r> well you define the name of the toolchain yourself :p
<n01> better using codesourcery
<n01> I had _a lot_ of problems with (i.e.) linaro
<oliv3r> nah, this is managed as a package by gentoo
<oliv3r> haven't had any issue YET with the toolchain
<oliv3r> it just works
<oliv3r> i hear a lot of talk about linaro
<tavishb> what exactly does 3:two_same_screen_diff_contets<screen0,screen1,fb0> (for A10) mean? two outputs are enabled with same contents(1 framebuffer)?
<oliv3r> gcc version 4.6.3 (Gentoo 4.6.3 p1.11, pie-0.5.2)
<oliv3r> erm
<oliv3r> Mentor Graphics decided to make a change in their site. Now in order to download their toolchain you have to register an account, which means giving them first name, last name, email, phone, company, job function, and country. So, even though the download is gratis, they are not delivering the tools as freely as before.
<oliv3r> that's allready a reason not to use codesourcery
<mnemoc> we have a direct link to download codesourcery's toolchain in the wiki
<oliv3r> but are you 'legally and officially' allowed to obtain it that way?
<oliv3r> anyhow, noty, not intersted
<mnemoc> sure, it's gpl
<mnemoc> the registration is just a annoynance, not a requirement
<mnemoc> they keep the files in a public server anyway
<mnemoc> no tokens or anything "unique" needed
<oliv3r> ok ok, atleast that's positive
<oliv3r> but if there's gcc-arm; why would I want to use their toolchain? I mean, if their patches are so good; they should land pustream eventually?
<mnemoc> only because it's the toolchain normally used by manufacturers
<mnemoc> and if you want to inject things it's better to match their toolchain
hipboi has quit [Quit: Leaving]
<oliv3r> that i can understand, but i have no reason to do anything like that
<oliv3r> i'll do some git bisecting tonight if I have time
<oliv3r> building, puting on www, downloading, is a little tiresome
<mnemoc> neither do I. I was only adding completeness about mentor's annoyance page to get the codesourcery toolchain
<oliv3r> lol thanks :D
<mnemoc> :p
<oliv3r> still, i odn' thave a working u-boot :( sunxi doesn't work with dtb; sunxi-current doesn't run period :S
<oliv3r> and was planning on documenting/testing more stuff today!
tinti has joined #linux-sunxi
<mnemoc> uhm
<hno> oliv3r, sunxi-current worked for me on cubieboard yesterday. But I'll try again.
rz2k has joined #linux-sunxi
<oliv3r> hno: it could be the DD job, i have to run it at work here, from XP, under cygwin
<oliv3r> so it may fail there
<oliv3r> but it displays the header, initial ram etc
<oliv3r> i'll run some comparisions to initial values that i found with our SPL, and compare it against that Allwinner u-boot +boot0 +boot1; something to do :)
<hno> U-Boot SPL 2013.04-00371-g791d2b5 (May 15 2013 - 13:53:44)
<hno> U-Boot 2013.04-00371-g791d2b5 (May 15 2013 - 13:53:44) Allwinner Technology
<hno> sun4i#
<hno> looks ok to me.
<hno> oliv3r, a copy of the binaries is at
<hno> the source is in my github repo. But tHere is only one completely unrelated change compared to linux-sunxi repo.
shineworld has joined #linux-sunxi
<oliv3r> hno: i'll try that, again could be that DD didn't work properly
<oliv3r> hno: is it worth, comparing md/mw/mtest results from allwinner stock nand boot, vs our SPL booted from mmc?
<hno> comparing what?
<hno> what are you looking for?
<rz2k> hno: is it possible to establish a data channel thru FEL and flash mtdblock partitions? I checked yuq's work and he uses tftp for getting images. for sun5i tftp is not accesible.
<rz2k> since you got u-boot working with FEL, I believe we can do it
<hno> rz2k, I not only have u-boot working but a full boot of Linux.
<hno> so anything is possible.
<rz2k> cool
<hno> not packaged up nicely yet, but works.
<rz2k> we can integrate it to sunxi-bsp
<hno> not so easy to integrate yet, but only small changes needed.
<rz2k> also I wanted to ask, does this include yuq's changes to kernel load address and etc. I saw he changed a lot of hardcoded addresses in his repo
<rz2k> not sure if it matters :p
<hno> I have not integrated the mtd changes yet. Needs polishing and reshuffling.
<hno> and no the changes to load address is not important.
stekern has joined #linux-sunxi
<oliv3r> hno: just comparing to the information we have/get, see if boot0/boot1 change any default values differently then what we do in SPL/u-boot
<oliv3r> hno: anyhow, if your u-boot boots, i'll have something to do again, so not that important :)
<oliv3r> hno: no, doesn't boot either :(
<oliv3r> so must be a dd-cygwin something
<hno> How are you dd:ing?
<oliv3r> XP 32bit; cygwin; dd if=u-boot of=/dev/sdb bs=1024 seek=32
<oliv3r> i get the initial bit, CPU, Board, DRAM, then nothing (SPL seems to load fine)
<rz2k> just in case anyone insterested, this is how yuq flashes his boards
<oliv3r> rz2k: i know he does some magic using livesuit, basically to bypass the randomizer
LoCoZeNoz_ZUE has left #linux-sunxi ["Too loud for my irssi"]
<oliv3r> hno: when you worked with slapin on mtd, you tried to get it to work without DMA, right? Does yuq's also do this? or he only implemented it with dma, and if we'd want it without, we're still equally stuck?
<oliv3r> anyhow, this fel boot is amazingly awesome to quickly test different kernels/u-boots etc; makes development a lot nicer
<hno> It's faster to tftp than fel, but sure.
<oliv3r> you mean because fel writes take longer?
<oliv3r> well my tablet for example, doesn't have ethernet :p
<oliv3r> also, i don' thave to 'copy binaries to tftp root, reboot etc'
<oliv3r> sure that can all be scripted
<oliv3r> but this just seems easier/better :)
<oliv3r> even if the actual write over USB is slower then over ethernet (which isn't available always everywhere)
<oliv3r> also, with tftp, you need console access (also lacking on my tablet) to initiate tftp
<oliv3r> just need usb console somewhere mixed in :D
<hno> kernel can have console on an usb gadged I think. But we have no usb gadged driver for u-boot yet.
<oliv3r> I might have a microsd breakoutboard before that happens though
<mripard> looks like more sunxi-based boards are coming :)
<hno> oliv3r, took me 19 seconds to load fel-boot + u-boot + script.bin + kernel + initrd (total 5.7MB) over FEL.
<oliv3r> mripard: $0!
<oliv3r> hno: ok that's quite slow :( but still workable i suppose
<oliv3r> mripard: looks like it'll be A20; with gigabit for the 'mediabox'
<hno> Well, it's probably faster than switching SD cards anyway.
<mripard> oliv3r: I think we can play the SoC guess game
<mripard> oliv3r: yep, maybe
<oliv3r> also 2gb ram
<mripard> with an A10 for the basic, and an A31 for the professionnal
<oliv3r> Mali400MP2 GPU (Dual Core)
<oliv3r> does also smell A20
<hno> 1.2G Dual Core ARM cortex-A8 processor ???
<oliv3r> probably copy paste fail
<oliv3r> cortex-A7 i'd guess
<oliv3r> the 'profesionall' fixes this
<oliv3r> also smells of A31 as mripard said
<oliv3r> but 35 for the torrentbox version
<mripard> the torrentbox could be an A13, given that it's also the cheapest
<oliv3r> that's raspberry pi pricein
<mripard> but the network speed doesn't match
<oliv3r> A13 compares quite well to the pi i gues
<mripard> and the SATA
<oliv3r> maybe it's a10 anyway?
<libv> bullboard doesn't inspire much confidence
<oliv3r> 480Mhz memory, i'm curious if they have awesome routing, or just did a simple test/estimate
<libv> 15k for designing 4 different boards?
<libv> and then he buggers up the A20 arm core type
<Turl> oliv3r: can't most devices run at 480?
<oliv3r> i suppose 3 boards are nearly identical, all a10/a20
<libv> no, not really
<oliv3r> Turl: I thought 480 was tricky sometimes, i thought 360 is 'most' some do 40x, cubieboard does 480, and could do 50x i belive
<libv> torrentbox is an a13
<oliv3r> libv: with sata and gigabit?
<libv> heh, vga output...
<oliv3r> usefull for your KVM in your serverroom :p
<libv> a13 doesn't have vga
<oliv3r> so A10 more likly?
<oliv3r> i still think there's some copy pasting errors there
<Turl> why would you do a torrent box without ethernet?
<libv> also looks like he is not privy to the a10 not really clocking to 1.2GHz
<oliv3r> 900 Mhz CPU + 300 Mhz GPU!
<libv> :)
<libv> bullboard is full of it.
<hno> libv, a13 can drive VGA with a little "LCD" output glue. See olimex board.
<oliv3r> there, made a comment to clarify things
<libv> oliv3r: urgh, now you helped this guy along in trapping some stupid indiegogoers
<libv> hno: to some extent
<libv> i had a dog of a time bringing that up 2 weeks ago
<oliv3r> hey, maybe it's legit!
<oliv3r> i wouldn't be supprised if its rebranded boards
<oliv3r> cubieboard with different branding :p
<libv> oliv3r: not for those prices
<oliv3r> download cubieboard specs, change logo; send to fab?
<libv> again, this a hungarian, and he's claiming that he is desiging _and_ shipping 4 different boards for 15k
<libv> cubieboi had a board design before he did indiegogo
<libv> and his revenue has been an order of magnitude bigger so far
<libv> all on a single board
<libv> with experience and connections in china
<libv> bullboard is full of it.
<libv> i just hope nobody halfway clued treads in it
<oliv3r> well it's a private message for ow, so i'm curious to his answers initially
<oliv3r> we can burn the witch after :p
<ssvb> DidiBsAs: hi, did you ping me the other day?
<DidiBsAs> Hey ssvb, yes I did. Got your nick from Youtube. I want to improve video performance on a mele a2000. And you suggested to increase memory speed to 480mhz I think. I'm trying to do that building my own uboot now.
<n01> ssvb: are you a youtube star? didn't know :)
<oliv3r> sexeh
<DidiBsAs> Hi n01 and oliv3r. I'm following this guide, got to the build of the SD card but it doesn't boot:
<oliv3r> DidiBsAs: what's your device?
<Turl> oliv3r: mele a2000 duh :)
<n01> who wrote this guide?
<oliv3r> oh yeah
<DidiBsAs> Mele A200, (it's a A10, right?)
<oliv3r> DidiBsAs: do you see WHY it doesn't boot
<oliv3r> DidiBsAs: yeap, think so
<DidiBsAs> oliv3r, I'm using ssh and the NAND OS is loading instead of the SD OS. Don't know if there's some kind of boot log I can see.
<oliv3r> you need to connect uart in that case to see why it's not booting the SD
<n01> DidiBsAs: have you uart to see u-boot log?
<oliv3r> might be it simply doesn't like the SD :)
<ssvb> DidiBsAs: if you already have some image that boots properly from the SD card, you can just dd sunxi-spl.bin and u-boot.bin to the right location on it
<DidiBsAs> Nope, don't have uart.
<ssvb> DidiBsAs: I don't have much experience with NAND myself, starting with just SD card should be much easier
<DidiBsAs> ssvb, sounds like a good idea, will try that.
<ssvb> DidiBsAs: and use to verify the actual memory clock speed
<DidiBsAs> Will try default speed, and if it works, will take it to 480 and use that, thanks again man.
<ssvb> yeah, sounds reasonable
<ssvb> also what is your screen resolution and refresh rate right now?

<DidiBsAs> I tried 800x600 1024x768 and 1366x768 and it looked pretty much the same, but I know more pixels = more processing required. Still, the youtube demo you posted looked flawless.
<ssvb> you mentioned running some office applications, they may be slow and CPU hungry themselves
<DidiBsAs> yes, but considering the performance I have now, I don't think too much improvement is needed, it looks like a video problem mostly

tinti has quit [Read error: Connection reset by peer]
<ssvb> DidiBsAs: that's easy to verify, you can profile your system and check what exactly is using most of the CPU
<ssvb> DidiBsAs: if it's Xorg process, then the graphics is likely the bottleneck
<DidiBsAs> Right, using top I saw that moving windows around a little bit takes Xorg to use almost all % of CPU.
<DidiBsAs> I read a lot that there are not open source drivers for Mali, what is sunxi using then?
<ssvb> Mali accelerates 3D graphics, the things like rotating cubes or first person shooters
<lunra> afaik copies are still not accelerated by the X11 driver (and probably never will be)
<lunra> You can reduce the problem of that by configuring your WM to only draw the outlines
<ssvb> lunra: copies can be accelerated using G2D, but this needs a reasonably recent kernel
<lunra> and disable your CPU meter, it's more trouble than it's worth unless you're a developer who needs to know whether his program is blocking for disk or in a busy loop in a pinch ;)
<lunra> ty for the info
w00tc0d3 has quit [Quit: - Chat comfortabel. Waar dan ook.]
<ssvb> DidiBsAs: when you are moving your windows, the CPU is maxed, but the overall performance should be reasonably fine
<ssvb> DidiBsAs: but when you are working with the application (to type text or do something else with it), the bottleneck contributing to slowness may be in the application itself
<DidiBsAs> Yes, it is possible.
<ssvb> DidiBsAs: also to make sure that moving the windows is not pegging the CPU, you may try to enable G2D acceleration
<DidiBsAs> How do I enable G2D acceleration?
<ssvb> Option "AccelMethod" "G2D"
<DidiBsAs> Right, on xorg config.
<ssvb> in the "Device" section of xorg.conf
ganbold_ has joined #linux-sunxi
<ssvb> but if you have an old kernel, moving windows will cause screen corruption
<DidiBsAs> G2D acceleration is being done by CPU, not Mali?
<ssvb> no, it's a dedicated 2D accelerator
<ssvb> part of Allwinner A10 SoC
<DidiBsAs> I have so much to learn...
<ssvb> Mali is a dedicated 3D accelerator
<DidiBsAs> I know that, but I thought there was no 2d accelerator.
<ssvb> and CedarX is a dedicated video decoding/encoding accelerator
<ssvb> in the case if somebody wants to watch 1080p movies
<DidiBsAs> Looks like the SD image I had is not using g2d, do you think screen corruption is the reason why it's not there?
<ssvb> you got the screen corruption?
<DidiBsAs> not yet
<ssvb> ok, just try it first and then ask :)
<ssvb> the chances are you have a recent kernel already
<ssvb> DidiBsAs: which office application exactly are you using? I may try to profile it
<DidiBsAs> libreoffice
<DidiBsAs> calc and writer
<DidiBsAs> you mean version?
<ssvb> well, knowing the version also would not harm
<DidiBsAs> ssvb, LibreOffice 3.6
<DidiBsAs> Pardon my ignorance, just cloned a10-meminfo, how do I run it?
<ssvb> "gcc -static -o a10-meminfo-static a10-meminfo.c" and then "./a10-meminfo-static"
<ssvb> as explained in the comments inside of a10-meminfo.c
<DidiBsAs> :$
<ssvb> hno: DidiBsAs has Mele A2000 which is already well supported, I only suggested to use a10-meminfo to verify the actual memory clock speed
<mnemoc> script.bin usually has several NULL fields, which we need to fill (using a10meminfo)

<slapin_nb> hi, all!
<slapin_nb> do anybody have insight on meaning of DDR3 settings of A10/A13?
<hno> yes.
<slapin_nb> hno: I need to know what I can fine-tune there
<ssvb> DidiBsAs: ignore this wiki page, it is for the people who have some weird new Android device based on Allwinner A10 and want to add support for it to u-boot
<slapin_nb> hno: and which options do I have re bus width and per chip bus width
<DidiBsAs> got it, ssvb
<slapin_nb> hno: and is per chip delay is implemented within controller
e-ndy has quit [Remote host closed the connection]
<hno> bus width is 8/16/32 (32 on A10 only).
<hno> it does have some kind of built in timing training, but know othing about the timing tuning registers, those are only given in binary form in script.bin with a reference that you get these from allwinner.
<slapin_nb> hno: can I ask allwinner to get the data for me, or should I sign NDA with them?
shineworld has quit [Quit: Leaving]
<slapin_nb> hno: I want to use 1 x 256M x 16 chip in big version, 2 x 128 x 8 in small version and 1 x 128M x 8 in minimal version, so I want to know what should I change in timing configurations
* slapin_nb wonders if he can enable getty in android like on OLinuXino on a stick to gather info and not bother with GUI
<hno> Most boards I have seen is using the same timing.
<hno> only different I/O width.
<ssvb> DidiBsAs: ok, will try to build libreoffice 3.6, it may take a while :)
<DidiBsAs> You are awesome, man. Thanks.
<ssvb> but my hunch is that it might be something like a spellchecker or whatever else causing the slowness
<ssvb> keep in mind that Allwinner A10 is not particularly fast in terms of processing power, maybe something like a 15 years old Celeron running at ~600MHz
<ssvb> if changing the screen resolution does not help much, it's very likely the graphics is not the bottleneck
e-ndy has joined #linux-sunxi
<ssvb> DidiBsAs: also it might make sense to chance cpufreq governor to "performance" or tweak "ondemand" as described at
<ssvb> unless you have tried this already
<DidiBsAs> nop, haven't yet. I need to write down all the things I need to try.
<luoyi> anyone have interest on writing a libva wrapper with cedarx ?
<luoyi> I think maybe this is the right way the make most video&audio app can use the power of cedarx
<ssvb> luoyi: let me guess, you? :)
<luoyi> studying libva src now. and still don't have idea on it
<luoyi> ssvb: you are cross-compiling the libre ?
<luoyi> I think it may cost few hours to get the job done
<ssvb> luoyi: natively compiling on a dualcore Cortex-A15, expecting it to take at least half a day
<luoyi> ArchLinuxArm already have the libreoffice package ...
<luoyi> ssvb: which distro are you work with ?
<ssvb> I prefer a build with all the symbols and debugging information
<ssvb> gentoo
<luoyi> so cool ... haha
<luoyi> and do you think the symbols and debug info will hurt the performance ?
hramrach_ has joined #linux-sunxi
<ssvb> no, that's just additional extra information which does not affect performance but greatly simplifies profiling and debugging
<luoyi> dualcore A15, you mean Samsung's Exynos 5250 ?
<ssvb> yes
<luoyi> chromebook
<luoyi> and the A15 binary code can work correctly on the AllWinner A10 ?
<lunra> I compiled linux-sunxi stage-3.0 on my chromebook, took less than 2 hours
<ssvb> it's the other way around, I'm compiling for -march=cortex-a8 and it works correctly on the chromebook
<ssvb> -mcpu=cortex-8
<lunra> then again I just realised libreoffice is like, libreoffice sized.
<lunra> the A15 has integer division which iirc the a8 does not
<ssvb> yeah, libreoffice is a huge monster, people must have a lot of faith in A10 to even try libreoffice on it :)
<DidiBsAs> ssvb, so you've gave it a try? is it a no-go then?
<ssvb> I gave it a try on my desktop computer, it's not particularly lightweight
<ssvb> on ARM it will take hours to get it compiled, that's currently in progress
<DidiBsAs> I just found an article about LibreOffice on RPi:
<lunra> google docs runs good >_>
<DidiBsAs> I'd like to use RPi, but hdmi only support is inconvenient.
<lunra> (in Chrome)
<lunra> Good is subjective though. I'm pretty patient, and at startup it's kinda slow.
<ssvb> DidiBsAs: if it can "smoothly run on Raspberry Pi" (whatever they mean), then it is even better on A10
<slapin_nb> We have been supporting them for more than one year and they are familiar with Allwinner chipset. What do you say?
<ssvb> DidiBsAs: if it runs slow for you, then there must be some good reason for this :)
<slapin_nb> damn IRC
<slapin_nb> I mean irssi
<slapin_nb> please ignore this one
<DidiBsAs> ssvb, that's what I thought, eventually it should work.
<DidiBsAs> Do I need to compile u-boot AND u-bootSPL to set the clock to 480mhz?
<ssvb> you compile u-boot and get both
<ssvb> have you already tried to run a10-meminfo?
<DidiBsAs> yes, I get 360 with my compiled uboot and with the original image one (guillaume's ubuntu)
<ssvb> good
<ssvb> with an updated u-boot you should get it reporting 480MHz
<DidiBsAs> Right, I'm editing u-boot-sunxi/board/allwinner/mele_a1000/dram.c .clock to 480
<DidiBsAs> Then I run: "make mele_a1000 CROSS_COMPILE=arm-linux-gnueabihf-" from /u-boot-sunxi
<ssvb> however 480MHz may be a bit too high for Mele to run totally reliable in all cases -
<ssvb> that said, 360MHz is way too low
<ssvb> mine is running at 432MHz at the moment
<DidiBsAs> Will try 420, still I get a u-boot.bin file but no spl
<ssvb> check 'spl' directory in u-boot source tree, the spl binary should be there
<ssvb> 420 is not the right choice, memory clock frequency is configured with 24MHz steps, so it is either 408 or 432
<ssvb> however I guess you would just get 408MHz if you set 420 in u-boot sources
<DidiBsAs> got it

paulk-desktop has joined #linux-sunxi
<ssvb> DidiBsAs: it should be sunxi-spl.bin, not u-boot-spl.bin
<ssvb> are you using as a reference? or something else?
<DidiBsAs> But try with guide now.
<DidiBsAs> rz2k, scripts from guide are creating the hardware packs, there's something wrong there probably, will try manually now
<rz2k> scripts from cnx software are outdated
<ssvb> the third-party blogs/articles tend to be outdated or incorrect, it's a good idea to keep all the information in linux-sunxi wiki and make sure that it is right
<rz2k> you should use sunxi-bsp
<rz2k> bsp provides "oneshot" command for building up hwpack and flashing it with rootfs from
<DidiBsAs> sounds good
<ssvb> just try to dd sunxi-spl.bin first, this may be enough
<ssvb> but then you also may want a recent kernel, and we don't know what you have installed at the moment...
<ssvb> so sunxi-bsp might be the best option in the end
<DidiBsAs> I need quantal develop respositories for gcc-4.7-arm-linux-gnueabihf-base, g++-4.7-arm-linux-gnueabihf, etc right?

<oliv3r> all we care is new android stuff or new google hardware
<oliv3r> if they don't share either
<oliv3r> who cares? :p
<mnemoc> they'll sell unlocked nexus-ized samsung s4... and gave away chromebook pixels
<n01> uhm ... chromebook could be interesting
<n01> still a bit too expensive
<mnemoc> the pixel is intel-powered and way overpriced to be interesting
<mnemoc> i was waiting for a $500-600 variant with exynos5410 inside
<oliv3r> yeah but the entry fee is like 1500 USD? so how is that 'giving away pixels'
<oliv3r> or a $300 AMD one :p
<mnemoc> oliv3r: they gave one to each attendee
<mnemoc> the rest is mostly only about google services and cross platform interaction
* mnemoc wanted a 10h pixel with exynos5 octa :'(
<oliv3r> well the entry fee is like 1500 USD, so you are buying a pixel mostly :p
<mnemoc> :p
<mnemoc> so the event becomes free
<oliv3r> if you have that kind of cash laying around
<n01> oliv3r: the company usually pays
<mnemoc> not mine...

<mnemoc> but yes, companies pay the entry fee and individuals get the gifts
<mnemoc> for those lucky enough to work for such companies

<ssvb> DidiBsAs: I understand that it's hard to debug this stuff without serial console
<DidiBsAs> it is, but looks like I'm closer, and I learnt a lot in the process
<ssvb> DidiBsAs: in the worst case, revert to some SD card image that is known to boot, and then just dd your compiled spl/sunxi-spl.bin and u-boot.bin exactly as explained in the instructions from the linux-sunxi wiki

<DidiBsAs> ssvb, actually, because I'm afraid I might have broke something in the process, I'm dding now a working image, to do that. Crossing fingers.
<oliv3r> since we have the same tablets, to get you started, that should work
<oliv3r> if that doesn't, either your SD card isn't recognized/liked by the tablet, or something else
<oliv3r> but hansg's images should work :) in theory
<DidiBsAs> oliv3r, when you say the same tablet, you mean we both have A10? Because Mele is not a tablet.
<oliv3r> DidiBsAs: i thought you had a broken tablet you wanted to use; i mistaken you!
<oliv3r> but the mele is also very well supported
<DidiBsAs> np :)
<ssvb> DidiBsAs: just in case, you don't need to erase and re-create partitions, just dd these two files
<oliv3r> the really big advantage with hansg's stuff is, it's known to work; so you take that as your basis
<oliv3r> then, if you want to swap out spl; dd it, if you want to swap u-boot; dd it; if you want to swap kernel, just swap it
<oliv3r> etc etc
<DidiBsAs> got it, ssvb and oliv3r. Will use this Fedora image next if I fail again:
rellla has quit [Quit: Nettalk6 -]
<oliv3r> that's the one, and only to get you started, test things and see how it all goes
<oliv3r> you don't even have to run the setup, the last 5? lines of the script is where it's all done
<DidiBsAs> Got to dd sunxi-spl.bin and it booted. Will change .clock memory speed and rebuild.
<hramrach_> hello
<hramrach_> ssvb: thanks for the hybris fix
<hramrach_> the file now plays fine
<hramrach_> but the [7] in the cedarx rendering chart crashes
* TheSeven slaps hramrach_ :P
* hramrach_ plays TheSeven in xbmc :p
<DidiBsAs> ssvb: ./a10-meminfo-static
<DidiBsAs> dram_clk = 432
<DidiBsAs> :D
<oliv3r> DidiBsAs: good job :)
<oliv3r> try 480 and run some stress test :)
<oliv3r> i know tom said the cubie could run quite allright at 520 even
<DidiBsAs> Will do, but first I need to re-enable vga. That's u-boot config, right?
<DidiBsAs> And what kind of stress tests or benchmarks do you suggest?
<oliv3r> mripard: why aren't things like thumb2 etc selected in the dfeault multi config, a10 does thumb2 does it not?
<oliv3r> mripard: I get this when building; did I pull a wrong branch :(
eebrah is now known as eebrah|away
<oliv3r> that was core-for-3.11 btw
<oliv3r> sunxi-next does the same
<oliv3r> on that note, bed time :S
<ssvb> hramrach_: hello, this looks like a generally problematic file, it is also played as a slideshow in the native android player
paulk-desktop has quit [Quit: Ex-Chat]
<hramrach_> but it does not crash
<hramrach_> yes, it is problematic
<hramrach_> I suspect it needs too much bandwidth
<ssvb> it does not crash for me in xbmc though, do you have a backtrace?
<hramrach_> it crashes only with hybris
<ssvb> not for me, I get just a slideshow but no crashes
<hramrach_> hmm, does not crash this time
n01 has quit [Read error: Connection reset by peer]
<hramrach_> so sometimes crashes :s
n01 has joined #linux-sunxi
<ssvb> on the other hand, after rebooting to android and now back to linux, I get blue colors on video playback in xbmc
<ssvb> the colors are fine in vlc
<ssvb> I remember some people reported something like this in the mailing lists, but I have not seen this before until now
<hramrach_> I get sometimes horizontal lines in vlc
<hramrach_> never seen the blue colors in xbmc
<drachensun> hno: I've got A31 devices, whats up?
<drachensun> I've got Linux booting on one too, just a minimal buildroot form though
<ssvb> hramrach_: lol, removing this weird seventh file from the xbmc video directory fixed the blue colors issue
<hramrach_> I get the impression that the hd playback is a lie
<hramrach_> you can play back HD stills and nearly-stills
Yaku has joined #linux-sunxi
<hramrach_> anthing with much change becomes a slideshow
<ssvb> hramrach_: maybe cedarx state gets messed up when generating thumbnails and encountering this file
<hramrach_> yes, cedar resets are not something well done in xbmc
Yakuz has quit [Ping timeout: 246 seconds]
<hramrach_> maybe the init of that crashy video was wrong but it still worked when it was first video to get played
<hramrach_> so there is something that carries over from previous video
<ssvb> yeah, this seems reproducible
<ssvb> hramrach_: can you try to put this problematic bb2.mp4 and Sintel trailer files into the same directory visible to xbmc, then open it, hover the cursor over thumbnails of these videos and then try to play the Sintel trailer?
<hramrach_> where is the sintel trailer?
<ssvb> in my case the snow (and everything else) becomes blue
<hramrach_> hmm, bb2 plays in software on i386
<hramrach_> so with moderate amount of computing power it's decodable
<ssvb> however mplayer complains a lot about "Missing reference picture" at least for me when playing bb2
<ssvb> it might be not strictly standard conforming
<hramrach_> cannot reproduce the blue snow
<ssvb> ok, and I can't reproduce crashes
<hramrach_> can't reproduce them either anymore
<ssvb> was it a fresh start of xbmc when you tried to test wrong colors?
<ssvb> maybe even rebooting would be better
von_fritz has quit [Quit: vonfritz leaves, don't panic]
<hramrach_> no, it was running already
LoCoZeNoz_ZUE has quit [Quit: leaving]
<ssvb> please try it again after rebooting, that's how it was reproduced for me (and xbmc may probably have some sort of thumbnails caching logic)
<hno> drachensun, stekern in #openrisc would like to probe the openrisc core a bit to know more of what openrisc implementation is embedded in the A31.
<ssvb> DidiBsAs: sorry for a distraction, you can probably try to run the same stress test as I did -
<ssvb> DidiBsAs: also you may first check if the system can boot with 480MHz memory clock (I guess at least booting should be always fine) and see if it improves performance
<hramrach_> cannot reproduce
<hramrach_> made a new directory for the test, rebooted, no blue tint
<ssvb> thanks, I'll try to see if there is something special needed to trigger this bug
<hramrach_> also re-compressing bb2 with x264 quiets the missing frame messages but creates artifacts
<hramrach_> the second scene gets jumpu and is smooth in the original encode
<ssvb> "mediainfo bb2.mp4" says that it was encoded on UTC 2004-06-13 01:10:04
<ssvb> and says that "The final drafting work on the first version of the standard was completed in May 2003"
<ssvb> maybe it was created by some early buggy encoder
<hramrach_> it also uses some isoc codec
<hramrach_> whereas x264 uses avc1

<DidiBsAs> Trying hansg's Fedora, does anybody has the root password?
hglm has joined #linux-sunxi
hglm has left #linux-sunxi [#linux-sunxi]
hglm has joined #linux-sunxi
<DidiBsAs> Couldn't load video on hansg's Fedora, I have a lcd VGA. Modified uEnv.txt with "screen0_output_type=4 disp.screen0_output_mode=1024x768
<DidiBsAs> " Suggestions welcome :)
<DidiBsAs> (on a mele a2000)
<hglm> I thnk the A10 doesn't support 1024x768....only 1280x1024 plus TV/HD resolutions
<hglm> Actually it does support 1024x768 on VGA...maybe you need a diffent syntax on the kernel command line
<hno> The FEL boot tool have been clened up a little and pushed to sunxi-tools.
<hno> tested on eoma68, cubieboard & A13-OLinuXIno
<hglm> @Didi Make sure you have "disp." before screen0_output_type=4
