<Turl> mrnuke: are you using linux-sunxi/sunxi-devel?
<mrnuke> mripard's mainline
<Turl> mrnuke: mripard branches do not have mmc support
<Turl> (19 is ENODEV btw)
<mrnuke> hmmm, then how does mripard test his stuff?
<Turl> mrnuke: ramdisk or nfs I suppose
<Turl> personally I embed a buildroot-made ramdisk on my kernel
<Turl> mrnuke: if you use this branch you should have mmc working https://github.com/linux-sunxi/linux-sunxi/tree/sunxi-devel
<Turl> also usb and sata and gmac :p
<mrnuke> devicetree or fex ?
<Turl> mrnuke: dt, it's bleeding edge mainline
<Turl> (plus stuff)
<mrnuke> sweet
<mrnuke> from the wiki, I got the impression that sunxi-devel is not mainline
<mrnuke> I must have mixed up fex with "more stuff than mainline" somehow
<Turl> mrnuke: mnemoc is working on a dt/fex hybrid too but that's 3.10
<Turl> anyway :)
<mrnuke> don't care about fex TBO. I just want a working dt config
<mrnuke> (so I can test coreboot :) )
<Turl> coreboot can boot dt directly? :o
<mrnuke> via uboot
<Turl> then you can boot fex too? :)
<mrnuke> theoretically yes, but fex==FUD in my mind
<Turl> dunno how can fex==FUD but w/e
<mrnuke> I don't know how to work with fex (uncertainty), I don't know if I can get it to boot (doubt). and I'm afraid I'd be wasting time with it (fear)
<Turl> haha
<Turl> it's just a compilable ".ini" file if you ever dealt with those
<Turl> bbl
<mrnuke> I need fex2bin and other tools, right?
<Turl> yeah, those are the (de)compiler
<Turl> (well, it's a single tool, fexc, the others are just convenience aliases)
<mrnuke> fuck that. I'd probably fuck up compilation of fexc or something
<Turl> booting simply consists of reading the binary version into a hardcoded address in memory, then the kernel is booted as with any legacy arm system
<Turl> hah - it's hard to fuck up `make`
<Turl> anyway, bbl
<mrnuke> cya

<Turl> wens: hmm, was I cc'ed?
<wens> you were listed in To:
<Turl> ah, here they are
<Turl> I was getting confused with your gmac series
<wens> yeah I've been sending a lot of patches. Even I get confused.
<Turl> wens: I did reply on "[PATCH v2 4/8] arm: dts: sun4i: rename clock node names to clk@N"
<wens> I moved the names for pll5/pll6 into factors_data in v3, so no extra output names
<Turl> I personally didn't like that much
<Turl> I'm not opposed to it though, as getting the last name is as ugly
<wens> I see
<Turl> otherwise the series looks sensible
<Turl> wens: dunno if we need that much verbosity on the binding doc regarding output names
<Turl> wens: we could dictate that all clocks should list their outputs or something to that effect
<wens> I guess we could require all clocks list the output, and then ignore the ones we don't use in the driver

<libv> but most of my (ex)SuSE colleagues have a subscription
<rm> of these, the beagleboard may turn out to be more popular than CT
<libv> the beagleboard has been around for longer
<rm> best = no argument here
<Turl> rm: and if they're comparing the pi.. well, not much to say on popularity :)
<libv> Turl: but it's nice that such a widely spread magazine does go beyond the rpi

<oliv3r> mornin\
<vector80> Hi oliver, good morning
<vector80> Hi, I feel something really really wrong about Allwinner android partitions.
<vector80> Under android: http://pastie.org/8634863#16,21
<vector80> Under debian SDCard: http://pastie.org/8634866
<oliv3r> what's the problem?
<vector80> Can you see, cylinder start and end points are wrong
<oliv3r> nah
<oliv3r> that's a msdos compatibility warning
<oliv3r> Fdisk under RHEL 6 or Oracle Linux 6 has a DOS compatibility mode. It can be turned off (and recommended by the man page) by using the -c parameter.
<oliv3r> As far as I understand, the warning "Partition 1 does not end on cylinder boundary" can be ignored since most hard drives after 1996 use Logical Block Addressing (LBA) and so the physical sector characteristics of a drive are no longer a relevant concern when aligning disk partitions.
<vector80> very good info
<vector80> but this causes one problem
<vector80> I want to use debian SDcard and NFS, to be able to dd if the android image
<vector80> but because of 1st partition,
<vector80> dd gtives "file too big" error
<vector80> and I can not grab the image from my eMMC
<vector80> can you recommend a solution for this?
<oliv3r> then your partition is to small
<vector80> No, as I wrote, I am using NFS
<vector80> NFS have at least 22Gbyte of space
<vector80> When I write my debian image to eMMC, I can easily grab its image to NFS, it works perfectly.
rz2k has quit [Read error: Connection reset by peer]
<oliv3r> wait, let me re-read :)
<vector80> But android partitions can't.
<oliv3r> though this can not cause a problem :)
FR^2 has joined #linux-sunxi
<vector80> oliv3r: my problem is, once I write sunxi uboot-kernel-rootfs to my eMMC, how can I recover it to be able to use android ... because you know, android image have boot0 and boot1, and my board have recovery button to enter FEL mode... But once I write debi,an image to eMMC, I must know how to enter to FEL mode...
<vector80> I feel I think I need one special uboot to enter to FEL mode directly
<vector80> Once I have seen such thing in wiki, but I can't find it now...
<oliv3r> we have an MMC image, that forces fel mode
<oliv3r> lets do a little asm talk
<oliv3r> FEL mode + BROM are stored at 0x4000 in the memory space of the SOC; it's like flash, but can not ever be changed, the BROM/FEL
<oliv3r> when the SoC turns on, it will always start executing code at 0x4000 first, that's just how it's wired
<vector80> up to this point, it is clear
<oliv3r> the BROM will run and check if you push the FEL button; it it is pushed, it jumps to FEL mode (which sits at 0x0002 (i forgot exactly, details are on the wiki)
<oliv3r> what this mmc image does; is the BROM will boot from MMC, as usual
<oliv3r> the first instruction in the FEL image is 'jmp(0x0002)';
<oliv3r> hence, it'll execute fel mode immediatly
<vector80> here is the feature request ( is it already available? ): current interra3_emmc.bin, can it include boot1 code, I mean, under sunxi uboot, if I press my RECOVERY button, can it enter recovery mode ?
<vector80> I mean
<oliv3r> if that's what you want/need: http://linux-sunxi.org/FEL
<oliv3r> vector80: the BROM has this feature, so including it in the emmc.bin is pointless
<oliv3r> BROM allready checks the FEL pin
<vector80> let me try
<vector80> nope
<vector80> if I press RESET button, and then press down recovery button, nothing happens, it just continue to uboot->kernel....
<oliv3r> if dd gives you a 'file too big error' that means, that your image is bigger then the partition, so it won't fit :)
<vector80> pressing recovery button has no effect if there is no boot1
<oliv3r> i think your are doing the order wrong; dd if=/mnt/somethingnfs of=/dev/mmcblk0p0
<oliv3r> vector80: you lie
<vector80> no I don't :)
<vector80> Let me show you the logs
<vector80> wait
<oliv3r> here
<oliv3r> this is the actual BROM from the chip
<oliv3r> boot() is the first function executed; read it :)
<oliv3r> check_ubooot is to check the fel button (allwinner calls it uboot, dont ask)
<oliv3r> keep the FEL button pressed and hit the reset button, while keeping it pressed
<vector80> oliv3r: I tried that too, it just continue
<vector80> maybe my recovery button code is different than your code?
<vector80> Let me show you the log, wait
<oliv3r> anyway, do you have sunxi-tools cloned?
<oliv3r> the BROM code is the same on all chips :)
<vector80> Please see
<vector80> This is how android image behaves on my board
<vector80> I press down RECOVERY button, and it enter FEL mode as shown above
<vector80> But when I do the same on uboot sunxi, it does not print anything, just continue booting uboot-kernel-debian...etc
<oliv3r> uboot ignores the fel button, it doesn't care, which makes sense, since the BROM checks the button
<oliv3r> anyway, checkout the sunxi-tools repo
<oliv3r> type 'make'
<vector80> I already did that before, now do it again?
<oliv3r> make fel-sdboot
<vector80> ok wait
<vector80> make'ing...
<vector80> one question, current kernel version is 3.4.61, wasn't it 3.4.67 ?
deasy has joined #linux-sunxi
<oliv3r> or make fel-sdboot.sunxi
<oliv3r> i think so
<vector80> I didn't checkout latest ?
<vector80> make: *** No rule to make target `fel-sdboot.sunxi'. Stop.
<vector80> make: *** No rule to make target `fel-sdboot'. Stop.

<oliv3r> yeah not working here
<oliv3r> but you need to compile fel-sdboot.sunxi :p
<oliv3r> trying to see why it won't compile
<oliv3r> i know i'm missing mksunxiboot
<oliv3r> well it needs CROSS_COMPILE= obviously
<vector80> ok wait
<oliv3r> btw, the BROM WILL not print anything if it enteres felmode
<oliv3r> push the FEL button, do a reset/power on
<oliv3r> do lsusb
<oliv3r> and check if it shows up
<ccube> hi, are there known issues with mmc driver on 3.4.67 (HEAD rev)
<oliv3r> you won't see anything in your terminal
<oliv3r> ccube: depends on your error
bbrezillon has joined #linux-sunxi
<oliv3r> vector80: don't worry abotu compiling
<oliv3r> vector80: sunxi-tools/bin/fel-sdboot.sunxi
<oliv3r> hno: where are the .lds files in the sunxi-tools repository
<oliv3r> ccube: nope that's no issue in our driver
<oliv3r> your mmc carde might be corrupt
<ccube> oliv3r, any ideas what else it can be?
hansg has joined #linux-sunxi
<oliv3r> ccube: worn out sd card
<oliv3r> insufficient power
<oliv3r> doesn't look like a broken FEX file, but could be
<ccube> mmc is not very old one
<vector80> oliv3r: I found that file, but it didn't get compiled, because there is no makefile
<oliv3r> ccube: i have a brand new one, that crashes constantly
<ccube> oliv3r, i also have random boot freezes and this on every boot: http://pastebin.com/NKZNd6C7
<oliv3r> vector80: /bin is precompiled; don't compile, just dd it to an empty sd card
<oliv3r> ccube: i think your PSU is broken; how are you powering your board?
<ccube> mobile phone charger with 2A
<ccube> samsung
<ccube> tried two different ones already
<ccube> it is not a stock olimex board. it is a custom one based on a10s. maybe there is something wrong with it?
<vector80> oliv3r: dd if=that_file of=sdcard seek=8 bs=1024 ?
<ccube> oliv3r, i am a bit confused, because a stock debian does not make any problems on that board
<oliv3r> vector80: aye; it's a micro-bootloader in a sense :)
<vector80> oliv3r: you are no:1 !!! I wrote that file to SDcard, and it entered to FEL mode directly
<vector80> and now writing... to eMMC or SDcard ???
<oliv3r> ccube: ah, a10s; i know there where some issues in the past; but i assume they where resolved (booting mostly i think) sounds like there's errors in the board
<oliv3r> ccube: you can try downclocking the memory to 360 MHz
maz_ has quit [Ping timeout: 272 seconds]
<oliv3r> vector80: wel you are now in FEL mode; so you can only use fel mode via USB from the pc
<ccube> oliv3r, thx i will try that
<oliv3r> vector80: but why do you want to enter FEL mode; and we should try resolving your dd issue first :p since dd from/to mmc should work without trouble; but dd is evil; (dd is awesome) loopback mount the image, copy the content
<vector80> oliv3r: Firstly I think we solved one issue
<vector80> 1st issue was, how to go back from debian to android by using that fel.sdboot file
<vector80> and it seems working,
<oliv3r> ah; well it still strange; FEL button works on all devices afaik
<vector80> PhoenixSuit said it succesfully wrote the image
<oliv3r> vector80: cool :)
<vector80> Let me double sure about that
dlan has joined #linux-sunxi
<vector80> oliv3r: Writing different android image... just to make sure...
<oliv3r> sure :)
<oliv3r> though even for android; you don't need pheonix suit :p
<oliv3r> though we don't have proper android images yet :(
<vector80> I don't need phoenix Suit? How to write android image to my EMMC then ?
<vector80> BTW: test is succesfull... I wrote different image, and double confirmed it... Thank you soo much again...
<oliv3r> mount -o loop android.img; cp -ar :p
<vector80> Pls tell me, is there an other way to be able to write android image to eMMC ?
<oliv3r> boot your master SD debian image, and copy the android files over :)
<slapin_> mripard: ping
<oliv3r> i mean you CAN use fel mode
<oliv3r> and sunxi currently doesn't have the tools yet to 'fel-mount'
<oliv3r> but quite possible though
<slapin_> mripard: do anybody actively working on DMA support?
<oliv3r> vector80: if your really board, write a fel program, that exposes the emmc over usb as storage device
<slapin_> vector80: some firmwares support android fastboot gadget
<vector80> oliv3r: You mean I must loop mount android image, and and overwrite eMMC ?
<oliv3r> slapin_: once you've done MTD stuff; we can start working on u-boot fastboot :)
<oliv3r> vector80: you could if you wanted too yeah
<slapin_> oliv3r: grrrrrr
<oliv3r> vector80: but that's all scriptable
<oliv3r> slapin_: :D
<oliv3r> slapin_: but our u-boot doesn't do fastboot yet does it
<vector80> ok, to be able to do this, I must be able to create android.img
<slapin_> oliv3r: what is the status with bbrezillon's driver?
<vector80> but currently, I can't create android.img
<oliv3r> vector80: yeah i don't think we have 'official sunxi android'
<vector80> oliv3r: you don't need it
<mripard> slapin_: the plan has always been to merge SPI with PIO, to later use it to debug DMA
<oliv3r> vector80: well, in the BSP you can do ./configure interra3_android
<oliv3r> and then make :D
<vector80> It is highly application based
<slapin_> oliv3r: leechie sdk u-boot does
<oliv3r> but i don't think the android build works yet
<oliv3r> slapin_: really, interesting; though to be fair, i think it's just a u-boot option isn't it
<mripard> I have SPI working since yesterday, so I guess I'll work on DMA in a few days
<vector80> for example, we are currently modified official android SDK a lot
<oliv3r> vector80: but you can use the allwinner sdk to build android, an 'image' that phoenix suit builds, isn't all magical :)
<bbrezillon> slapin_: I've added HW ECC (I'll post a new series with HW ECC support soon)
<slapin_> oliv3r: I don't think it was already integrated, but I have not checked lately
<vector80> modified launcher, modified default home app, modifying SystemUI
<mripard> but I'll be working on the A31 probably, so feel free to start working on another SoC
<vector80> Even we need to make OTA with android
<vector80> According to official sources from allwinner, nobody did that before
<vector80> And we have to do :(
<vector80> Anyway, lets go back to dd if issue
<vector80> I am booting over TFTP-NFS now
<bbrezillon> I'm still experiencing weird things: when I write on the 4th page of a block I get a lot of bitflips on the 1st one (too much to be corrected by the ECC hw or soft)
<vector80> wait
<slapin_> bbrezillon: how do you handle different random seeds and boot blocks?
<bbrezillon> randomizer is not yet implemented, thought I tested it a bit with a fixed seed (0x4a80)
<slapin_> bbrezillon: I think we can fight this one, can you post the full patch set on the list?
<bbrezillon> sure
<slapin_> I'll have tons of time tomorrow
<bbrezillon> I'll do it today
<slapin_> bbrezillon: by full, I mean full state, not only ECC-related
<JohnDoe_71Rus> oliv3r: BSP does not give the correct android kernel
<slapin_> bbrezillon: does it work without DMA?
<bbrezillon> no
<slapin_> hno: hi, do we have sunxi in mainline u-boot yet?
<slapin_> bbrezillon: too bad, but how do you test it then as there is no DMA support in mainline yet?
<bbrezillon> I'm not using DMA at all
<slapin_> hno: I want to post u-boot related stuff for review
<wigyori> morning
<bbrezillon> I managed to get this working without DMA access
<slapin_> bbrezillon: ah, that is perfect
<slapin_> bbrezillon: I did it too, that is good
<slapin_> bbrezillon: and hno did, for that matter
<vector80> oliv3r: Booting NFS is ok now
<slapin_> bbrezillon: can't wait to see your work (and add randomizer on top)
<slapin_> vector80: have you managed to run Android off NFS?
<vector80> here is my info: http://pastie.org/8635008
<vector80> slapin_: I have done that on IMX6 before but never tried on AW

<slapin_> vector80: well, I failed a month ago and was told that it is not possible due to how android treats network, etc, so I stopped, but I have a real need for that as there is device with 10G ethernet, 1G RAM and 2MB NAND chip inside (IPTV box left from unsuccessful project) which I want to use for kid's movies, so I'd like to know of possible solutions to problems
<vector80> slapin_: it was very hard to do on imx6 too
<vector80> slapin_: You are experiencing problems after kernel , right?
<vector80> I mean, kernel is decompressing and starting device drivers,
<slapin_> vector80: yeah, kernel boots fine off bootp
<vector80> but when it comes to init, many things fail and it collapses, right?
<slapin_> vector80: basically, yes
<vector80> right
<vector80> I expeienced same thing on IMX6 too
<vector80> There was a very good PDF file
<vector80> it explains how to boot android over TFTP+NFS on IMX6
<vector80> I have did things on that PDF one by one
<oliv3r> slapin_: we aren't mainlined yet, but we are on par with mainline; patches need big cleanup sthough
<vector80> there were still issues but finally I managed to do it succesfully, it take about 3-4 days
<vector80> But you people are much more experienced than me, you have good knowledge about linux, may be you can do it in hours
<vector80> let me try to find it for you
<slapin_> oliv3r: so, you mean no SoC in u-boot yet?
<vector80> slapin_:
<vector80> slapin_: I found my notes
<oliv3r> vector80: :p
<vector80> How can I give it to you?
<oliv3r> slapin_: no sunxi soc no; it's all on our github
<vector80> Do you have email ?
<oliv3r> slapin_: but hno keeps it in sync with mainline
<vector80> slapin_: I upload here: http://efshare.com/?s=4H5H76
<vector80> slapin_: I think you may do it on aw too
<vector80> I just can't understand why aw did soo many good and soo many stupid things...
<slapin_> vector80: thanks a lot!
<slapin_> oliv3r: not even the smallest, tiniest SoC? too bad :( then I can't upstream NAND driver... that needs to be fixed, and fast... hno, are you here?

<ccube> oliv3r, still probleatic with 360mhz. when cold booting the board i am getting a kernel oops with sometimes stuck, sometimes automated reboot. after the automated reboot the system comes up (with the previously posted stacktrace in boot log)
<sgo11> Currently, my ubuntu is working fine. but in linux-sunxi wiki, I saw this sentence "you should also eventually install cpufrequtils to set up an acceptable CPU-behaviour". Do I need to worry about that? How to determine if my CPU is working fine? thanks.

<bbrezillon> could you test writing on the first 5 pages of a block, and see if you got bitflips on the first page ?
<slapin_> bbrezillon: I'll do a lot of tests, including this one

<oliv3r> ccube: that looks like a 3.3 kernel?
<oliv3r> but i don't recall; default sunxi kernels ahve it all one if im' not mistaken; but make sure you pass the proper bootargs
<ccube> ah maybe the defconfig is the problem
<ddc> I'm having a hard time getting csi to work with the ov7670 does any have any luck .

<nikrou> oliv3r, some days ago, you proposed me to install fedora on sdcard to boot my tablet blocked in recovery mode. Do you think I could restore it from the dump of all my nands ?
<nikrou> I successfully boot my device with debian on sdcard but after I don't know what to do to restore my android system on nands !
<nikrou> Any idea ? Is it possible ?
<oliv3r> nikrou: technically; sure
<oliv3r> nikrou: but first you probably want to see if you can loop-mount your images
<WarheadsSE> arokux: looks like they overlooked ath Arch runs on all those..
<WarheadsSE> as usual..
<libv> ah, nikrou
<libv> with the rebadged inet_86vz
<arokux> WarheadsSE: no, there is a mentioning of Arch, in the list of the distros, I think, don't have an article right now
<libv> nikrou: i see that you've created an account
<libv> nikrou: did you manage to take a picture of the backside of your device?
<libv> nikrou: also, you had access to some android configuration files where you got the board identification data from
<WarheadsSE> arokux: only mentions it on the Pi
<arokux> oh, ok, well, c't is a phoronix like magazine as for me. i just read some articles it because it lies around
<oliv3r> nikrou: do you have access to your tablet when booting from fedora/debian? e.g. ssh, keyboard, something?
jemk has joined #linux-sunxi
rz2k has quit [Remote host closed the connection]
<WarheadsSE> arokux: mm
<WarheadsSE> relating it to phoronix (moronix) makes suddenly more sense as to why massive details are missed.
<libv> arokux: it really is quite good in comparison
<libv> arokux: as i stated many hours ago, several of my friends/colleagues swear by it, and in my nokia days i made sure i had 2-3 copies saved up for planerides
<wens> oliv3r: you could try copying the SDIO IDs and drive strength stuff
<oliv3r> wens: was thinking of doing exactly that
<oliv3r> patched looked really smlal
<hno> bbrezillon, I have one of these: http://www.seeedstudio.com/depot/preorder-open-workbench-logic-sniffer-p-612.html?cPath=75 quite sufficient for looking at NAND commands even if the sample buffer is quite small so longer sequences need to be collected in many tries.
<hno> and it's easy to run the nand controller at low clock if needed, and might be while measuring as the probes do disturb the bus a bit.
<libv> WarheadsSE/arokux: this will get a signification portion of german it folk to look into the allwinner boards (which are 3 out of 5)
<libv> and it will get us a few good folk as a result
<oliv3r> libv: well i'll be damned
<oliv3r> Puneet B helped jonsmirl fix his issue
<libv> oliv3r: hell did freeze over last week
<oliv3r> if we get 1 new dev from this; a 'stick around one' then that's a win

<oliv3r> nikrou: i don't remember :)
<oliv3r> nikrou: if you have ssh access, can you do fdisk -l /dev/nand? do you see partitions at all?
<hno> yes there is plans, just need to figure out how to make 36-hour days...
<nikrou> I see no partition
<nikrou> only nandg created by CWM
<oliv3r> hno: yes! we need you to have more sunxi-time :p
<oliv3r> nikrou: that's ok
<oliv3r> nikrou: try to get nand_part running on the tablet
<hno> allwinner partition table is not recognised by fdisk. You need nand-part from sunxi-tools to work with those.
<oliv3r> nikrou: its in sunxi-tools; you will hvae to cross-compile it (shouldn't be a problem; i can send you a binary if you can't manage it or you can check the /bin dir)
<nikrou> I've got an error when try nand-part don't remember it
<nikrou> I will give it another try.
<mripard> oliv3r: so, you're the one I should ping for my A31 uboot patches ? :)

<hno> oliv3r, job of patch monkey is to do a final review on style cleanness (no other unrelated stuff), verify that there is sufficient community testing/review and judge if there might be a risk of regressions in other areas, then merge if passing tests.
<hno> no one can master all technical areas. I certainly don't.
<hno> note, tests is those listed. Not functionality testing (community peer review takes care of that).

<vpelletier> hi. I have a WITS Colombus A31 and would like to boot linux on it. I have the development kit's dvds with kernel, u-boot, buildroot source (and a few more folders), and I've quick-read a few provided pdfs, but I cannot find a description of how I can get it to boot on something else than pre-flashed content
<vpelletier> is there a standard way of booting from SD, for example ? (there is no eMMC on board)
<hramrach> vpelletier: see the linux-sunxi.org wiki
<hramrach> maybe their u-boot does not do mmc
<vpelletier> well, the in-flash u-boot has a 0 timeout
<hramrach> sunxi u-boot does mmc but not nand
<vpelletier> I do see "press any key to interrupt", but it doesn't react
<mripard> vpelletier: you need to hold the button next to the four component connectors while powering it to boot on SD
<vpelletier> ah, so that's the "u-boot" button
<hramrach> it no longer autoboots?
<vpelletier> so my SD image is doe wrong
<vpelletier> yes
<vpelletier> at least, no output on UART0, while I get some when not pressing that button
<mripard> hramrach: nope
<hramrach> secure ;-)
<vpelletier> ooh, boot from usb
<libv> hno: for a dead branch?
<libv> hno: i could just as well drop them, as they were only there to help me find why it failed to do anything
<libv> and i thought they might be useful for others who will undoubtedly run into the same issue
<hno> vpelletier, if it's the dev board then there should be a boot selector jumper.
pwhalen has quit [Read error: Operation timed out]
<vpelletier> hno: there is a "u-boot" button next to the component connectors, as mripard mentioned, which indeed affects boot (ie, nothing output on UART0 when held on power-on with no SD inserted)
<vpelletier> I'm reading the SD creation page right now
bsdfox has quit [Ping timeout: 260 seconds]
FR^2 has quit [Quit: Connection reset by peer]
<hno> vpelletier, usually that button enters FEL mode. But maybe it also probes for SD on A31, don't remember.
<hno> Right, it does.
<hno> thanks mripard
<vpelletier> if I understood ARM boot sequence properly, SPL is resposible for setting up the hardware before loading the next loader. is this right ?
<vpelletier> (ram timings, ...)
bsdfox has joined #linux-sunxi
<hno> vpelletier, yes.
<vpelletier> which means that having the right SPL is critical for the board to work, and I do not seem to find one in the WITS-provided tarball (containing code and a few binaries)
printallthething has quit [Quit: Leaving]
<hno> WITS do not use u-boot SPL. They use Allwinner boot0/boot1.
kivutar has quit [Quit: Ex-Chat]
<mripard> vpelletier: could you make an iso image of the dvd, and upload it somewhere?
<vpelletier> I did find a sys_config.fex (plain text) file describing what I understand as pins, voltages, frequencies, etc which I believe belong to that SPL
<mripard> there was none shipped with mine....
<hno> vpelletier, sys_config.fex is Allwinners "device-tree" source file for their custom configuration system.
<hno> mripard, Eva might give you a download link if you ask.
<vpelletier> hno: so something else exists that SPL would be based upon ?
<hno> SPL means the u-boot SPL developed boot loader.
pwhalen has joined #linux-sunxi
pwhalen has quit [Changing host]
pwhalen has joined #linux-sunxi
<hno> community developer boot loader.
<vpelletier> ah, when I said "based", I meant that SPL needs to know some values about the board so it can initialise it correctly, not where the source comes from
atsampson has quit [Quit: kernel upgrade]
<vpelletier> ie, some board-specific config file
<hno> vpelletier, it also needs A31 support. We only have sun[457]i support in SPL yet.
<hno> a31 is sun6i.
<libv> there really is noone who cares for sun6i
<libv> let's hope a23 gets a development board out soon
<vpelletier> libv: any reason why sun6i would be uninteresting ?
<libv> vpelletier: for me, because of pvr
<libv> vpelletier: for others, i do not know
<hno> pvr is the main setback for most I think.
<libv> a80 is then going to be ignored just as much :(
<vpelletier> what is the powervr status ? no graphics at all, or no accelerated 3D ?
<Turl> A80, if with sata and usb3, could have a place in NASlike devices
<libv> vpelletier: i will not touch it with a 10' pole
<hno> libv, any reason why you look at a23 instead of a20?
<libv> hno: i wanted to buy an a13 tablet a month ago
<libv> hno: and was quite surprised when i opened up the thing up
<hno> libv, right..
<libv> hno: it is higher clocked than the a20
<hno> libv, given prior track record it should be quite similar to a20. Have you got console access working?
<rz2k> hno: have you read the u-boot source for A23?
<rz2k> it is in the sources that vector80 dropped

<oliv3r> hramrach: vpelletier a31's BROM has different boot order; it checks pins, see the BROM page i think on the wiki
<ccube> is there a RTC on a10s board?
<oliv3r> rz2k: have you seen the u-boot sources? afaik they odn't do memory init there,s o marginally interesting

<ccube> a10s is sun5i i think
<nikrou> olivr: when you said there's special patches for building a sunxi kernel do you mean I need to follow steps on that page : http://linux-sunxi.org/Installing_to_NAND_from_SD_card
<oliv3r> nikrou: no; fi you have the sunxi 3.4.6* kernel; those patches should be there; if you are using 3.3 or older kernel; i don't think it has them
<oliv3r> but i never had to use nand_part yet
<ccube> so "hwclock: can't open '/dev/misc/rtc': No such file or directory" are expected and i should disable thin in my kernel

<hramrach> a pair of dip switches could give you boot device selection
<arokux2> ugh.. after distro upgrade I cannot run lots of programs if there are too much files in the working dir
<oliv3r> hramrach: it allows you to always boot from a certain media; excluding the others; so it's usefull i usppose

<oliv3r> nikrou: someone here should know :)
<nikrou> but who ?
<nikrou> What I read on forum is I must reinstall a new ROM. No other solution
<nikrou> But I cannot find a rom that livesuit wants to flash

<oliv3r> nikrou: i don't think your rom is corrupt :)
<oliv3r> nove: that it is :)
<nikrou> But I don't have a rom
<hno> I haven't seen the a23 u-boot sources. Might be interesting for spotting if there is any general differences in hardware, but do not contain anything needed for SPL.
<nikrou> I hope I can build one following a tutorial by modifing an existing one with as much as possible similarities
<oliv3r> hno: we have the sources, but it's not hosted yet

<hno> nikrou, the nand driver failed to recognise your nand chip I think.
<hno> oliv3r, should be stuffed into git..
<oliv3r> nikrou: i'm running hasng's fedora 19; and gparted shows /dev/nand quite happily
<oliv3r> hno: yeah; mnemoc's laptop broke this week; so he can't do anything from home atm
<oliv3r> he should get his new laptop one of these days
<hno> found one in stulluk.
<oliv3r> but u-boot should be cloneable
<oliv3r> stulluk IS vector80
<oliv3r> er branchable and pushable
<oliv3r> but with my book; fosdem; and #linux-sunxi distraction i've been a little busy

<hno> copied it to /SDK/ for a start,
<hno> Hmm.. readme says sun6i??
<hno> but pack says chips/sun8iw3p1
<hno> so yet another generation?
arokux2 has quit [Remote host closed the connection]
<hno> right, it is sun8i
arokux2 has joined #linux-sunxi
<hno> wonder what they do when they reach 10..
<libv> sue us for taking the name?
<hno> no boot0/boot1 sources in this sdk :(
<libv> grmbl
<hno> was hoping the a20 sdk had set a new standard on that
<oliv3r> hno: they started to 'unify'

<oliv3r> hno: disassemble, connect lvds to cubie
<hno> there is a sun9i_defconfig in buildroot.
<oliv3r> i don't recall that one
<oliv3r> a23 is sun8i; no clu ewhat sun9i is supopsed to be
<oliv3r> hno: did i mention, that a23 mem controller is likly to be sun6i based?
<hno> there is also a sun9i defconfig in linux tree,
<hno> oliv3r, why?
<oliv3r> fex file
<oliv3r> libv linked his
<hno> ok. ouch then..
vpelletier has quit [Quit: leaving]
<oliv3r> but we have a31 boot0 source to extract that from

<oliv3r> and we should have standby code to veryfy against

<oliv3r> additional 4 and 6, no 5 and 7
<arokux2> oh, you've got A23 sdk, from where?
<hno> where is a31 boot source?
<hno> there was no standby code in A20 SDK from what I recall. Only a binary blob.
<hno> but seems to be full standby source in A23 SDK at least.

<oliv3r> hno: we never 'officially' got it; but some of us have it still; with git history
<hno> right, that one.
<hno> the sun7i branch there was quite far from the a20 sdk source drop however.
<oliv3r> still; should be helpfull
<hno> yes
<oliv3r> i find sun[89].c files there instesting
<oliv3r> the map_desc struct
<oliv3r> don't understand why one is so much bigger then the other
<oliv3r> they still use the same watchdog for reboot though :)
<hno> where=
<hno> linux mach-sunxi/sun[4689].c?
log0ff_ has joined #linux-sunxi
<oliv3r> yeah, but no 5 and 7 i
<oliv3r> and i'm reading 8 and 9
<oliv3r> thinking they'd be very similar
<oliv3r> well they are i guess
<oliv3r> just the mapping i don't understand
<oliv3r> like why does sun8i rev 1 need to define the video engine
<hno> #define SUNXI_DRAM_PBASE 0x20000000 /* 0x20000000 ~ 0x220000000(size: 8G) */
<hno> from sun9i... they are going for large address space?
<hno> looks like both sun8i and sun9i have openrisk core for deep suspend mode. No dram code in standby code, only message passing to something and lots of SUNXI_R_--- I/O blocks.
arokux2 has quit [Remote host closed the connection]
<hno> time for bed. More digging later.
<oliv3r> yeah a23 has an 'arisc' remote_proc, wingrime found that they likley currently use it to play back audio
<oliv3r> in sleep
<oliv3r> could be usefull for audio applications in general
<oliv3r> sun9i is quite likly to be the a80
<oliv3r> so should show hints of powervr
<lkcl> oliv3r: oh bloody 'ell not another one :)
<lkcl> oliv3r: well, with that manager now gone - the one who was deliberately causing GPL violations - it should be easier to sort out.
<oliv3r> lkcl: we've had it for a little bit; but yeah, libnand, no boot0/1
<oliv3r> lkcl: oh really? do tell
<oliv3r> this is news!
<lkcl> could you email me what's involved?
<oliv3r> same as always
<lkcl> oliv3r: it shouldn't be!
<lkcl> this happened ages ago (months back)
<oliv3r> BROM/boot0/boot1/libnand/cedarX (though we got better cedrus now anyway)
<lkcl> oliv3r: email me what's missing / involved, i'll remind them ok?
<oliv3r> sure
