<xtofury> ok looks good, battery is about to die, so if I build the whole sdk using lunch and make it should include it now?
<Turl> xtofury: ah, you're building android?
<Turl> xtofury: you'll need to replace the defconfig with the .config you just generated with menuconfig and clean the kernel tree with make mrproper

<robb83> hi
<robb83> i build sun6i kernel and u-boot from allwinner repo, but I do not know to test, can anyone help ? (qemu board or somthing)
FR^2 has joined #linux-sunxi
<rm> no qemu
<rm> boot it on the actual board
<rm> if it doesn't boot, attach a serial console and see what's wrong
<robb83> i have no a31 board, but tablet, create sdcard for booting, but nothing happend
<mnemoc> a31 needs you to press the FEL button to boot from uSD
<mnemoc> hansg!
<robb83> Yes I tried, but I'm not sure that it works
<mnemoc> the whole family of sun5i defconfigs failed to build with the latest for-amery from hansg :<
<oliv3r> robb83: how are you builing sun6i u-boot, when we have no sun6i support (other then the few patches i have up on my wip/branch
<oliv3r> so unless you have some special allwinner SD u-boot, it's highly unlikly this will work
<oliv3r> unless of course someone finished a31 support in my vacation
<robb83> build from:;a=shortlog;h=refs/heads/allwinner-sunxi-a31
<oliv3r> that's u-boot which lives in nanda
<oliv3r> e.g. the uboot from boot0 -> boot1 -> boot.asf -> u-boot
<robb83> ohh
<robb83> thanks, thats new for me
<oliv3r> we have practical zero u-boot support right now :) i started a few patches, but that's on very low prio rigt now :)
n01 has joined #linux-sunxi
<robb83> want to deal with it? difficult to rewrite sd?
iamfrankenstein has joined #linux-sunxi
<robb83> or modify my nand directly with usb firmware updater or android ?
<oliv3r> it's a lot of work, and don't want to deal with it right now, also I lack a31 hardware, and with the powerVR in their, my motiviation is limited. I started it because it was interesting and exciting at start ;)
<oliv3r> but as i write more,it becomes harder to test as i have no hardware :)
<oliv3r> in a few weeks time i might work on the dramc a bit more
<robb83> same are, no hardware :(

<oliv3r> sdk: what u-boot are you using? (and what SPL?)
<sdk> robb83: yes, that guide and also Everything compiles ok.
<sdk> oliv3r: U-Boot SPL 2013.07-08154-g48845ec
<oliv3r> you've build from git?
<sdk> oliv3r: how to find u-boot version? Above I got from serial console output.. Yes. Built from git
<oliv3r> which config are you using?
<oliv3r> each board needs its own config
<oliv3r> can you copy/paste the entire SPL output?
<oliv3r> since it should show you the board it was compiled for
<sdk> U-Boot SPL 2013.07-08154-g48845ec (Aug 21 2013 - 09:37:17) Board: A10s-OLinuXino-M DRAM: 512 MiB CPU: 1008000000Hz, AXI/AHB/APB: 3/2/2 SUNXI SD/MMC: 0
<oliv3r> that sounds about right
<oliv3r> incidentally, i have the same issue with my cubie2, but that's my fault :p
<oliv3r> can you verify u-boot is properly written to the SD card? (bs=1024 seek=32)
<sdk> yes, the original Olimex SD-card gives the same output, but of course that one does load the next stage. For my own card, it stops here.
<sdk> yes, triple checked
<oliv3r> did you try extracting the u-boot from the 'original' card and copy it to yours?
<sdk> that's interesting. I'm not sure how to go about doing that though.
<oliv3r> dd if=/dev/mmcblk0 of=u-boot.bin.orig bs=1024 seek=32 count=.... (don't know u-boot size exactly)
<oliv3r> i guess using the size (in kb) from your current u-boot should be a good indication
hramrach has quit [Remote host closed the connection]
<sdk> ok I'll give it a try.
<oliv3r> 226 it looks like
hramrach has joined #linux-sunxi
<sdk> nope it makes no difference. it's strange
<oliv3r> SD card broken?
<oliv3r> dd if=/dev/mmcblk0 of=dump.img bs=64k
<oliv3r> (dump entire SD card)
<oliv3r> then, write it to your own card and see if it works, I suspect it also does not work
<sdk> yesterday I wrote the olimex image to it, and it worked. so I don't think that it's broken
<oliv3r> you can also first try to copy SPL (maybe SPL is wrong)
<sdk> yes I'll try that
<oliv3r> sd cards break without notice :)
<oliv3r> there's no flash wear lvling layer, or not a good one
<sdk> yeah you're right :)
<oliv3r> mine actually blew up and cracked
<oliv3r> it was only 128mb so i didn't care, i used it for mainline test kernels
<oliv3r> but it baffled me
<oliv3r> woprr: did you find if it all really overlapped
<sdk> mmh. now SPL not booting as well. it's weird, first I dd 23 records to spl-orig, then dd'ing that file to the card it says 31 records out.
<oliv3r> spl is 22 or 23 bytes, to that sounds sane
<oliv3r> ok try downloading SPL and u-boot from olimex, I can't imagine them not hosting the binaries somewhere
<oliv3r> they are very OSS friendly
<oliv3r> get those and dd those (saner then extracting and writing)
<oliv3r> SPL can be no larger then 24k
<oliv3r> so you could try extracting 24k and writing 24k 'just in case'
<oliv3r> the BROM will not ever read more then 24k (hardware limit) so that should be safe
<sdk> ok, i'll look for the files on olimex site..
rz2k has joined #linux-sunxi
<oliv3r> sdk: the SPL and u-boot from git _should_ work, we just have to find out why it's not working now
<sdk> yes. well the only differences wrt olimex article I can see are that I'm using gcc4.7 and saying "make .. arm-linux-gnueabihf-" instead of "arm-linux-gnueabi-"
<oliv3r> that string is just a name that you give to your toolchain, weren't there some issues with gcc 4.7? i don't know if those have been resolved and if those applied to u-boot at all
<oliv3r> let me build a spl + u-boot for you
<oliv3r> in 20 minutes
<oliv3r> gotta test my own u-boot first
<oliv3r> to see if the code still works ;)
<sdk> ok tnx

<oliv3r> bah mine's not working give me a bit more time ;)
<sdk> ok, hope it will work..
<sdk> i got it working now. using the olimex git snapshot git checkout v2013.07-rc1-sunxi and re-building then it works!
<sdk> so something must have changed along the way, breaking it
<oliv3r> that's interesting
<oliv3r> what hash tag is their snapshot that you are using?
<sdk> sorry, git noob, how to get hashtag?
<mnemoc> git log HEAD | head -n1 should do
<sdk> commit 57ff4519ba0f47f1647f7def5864ae4c9ef3e6a0

<oliv3r> for what it's worth, my SPL isn't booting on cubie2 either ;)

<sdk> ok.. it must be something is broken in the u-boot. hope it will be fixed but for now i can go on and use the old version. I'm copying my own rootfs to the card now.. see how that goes.
<oliv3r> hno: ping
<oliv3r> sdk: well on the upside, it wasn't my patchseries that broke it :)
<oliv3r> hno: 29689232f8a4d1640e551ef433176b81cecfa9c7 i just checked out and that still works, so gonna try to find which patch breaks it, but i have a very very slow testing method (build, upload, download, put on SD, put in cubie linaro, dd, reboot cubie

<oliv3r> hmm, i seem to miss-understand how git bisect works :S
<oliv3r> 29689232f8a4d1640e551ef433176b81cecfa9c7 is my last commit and i tested that, which works. so I'll use that as base reference (work on cb2)
<oliv3r> so the breakage should be somewhere after that and before HEAD, so I use git bisect start HEAD 29689232f8a4d1640e551ef433176b81cecfa9c7 --
<oliv3r> the first hash it checks out is: 934128bcd98106e764d2f492ac79c38ae53d] Merge branch 'master' of git://
<oliv3r> so i assume it checks out 934128bcd98106e764d2f492ac79c38ae53d but when I do git log, my patches are all gone, boards.cfg lists no allwinner device?
<oliv3r> so how do I use git bisect?

<atsampson> oliv3r: I'd normally do it as separate commands, although I don't know if it actually makes a difference
<atsampson> oliv3r: i.e. checkout the latest version, "git bisect start", "git bisect bad" (to say this version's bad), then "git bisect good <the hash of HEAD>"
<atsampson> then it should grab a version in the middle for you, and you can do "git bisect good/bad" as appropriate

<oliv3r> i'm not quite sure how that ID is made up tbh
<boycottg00gle> me neither
<oliv3r> i first thought it was the git hash tag, but that's not the case (the gc0f part)
<oliv3r> it appears spl might work, but u-boot is broken
<boycottg00gle> ah my local sunxi-current branch is on: c0f3b94d

<eagles0513875_> ok guys i am making some progress with booting now the next issue i am having is no login screen. here is my current output to the serial port
<eagles0513875_> any ideas would be greatly appreciated
<n01> eagles0513875_: it is not that you don't have login screen. Your kernel is not booting at all
<eagles0513875_> Turl: any ideas as to the above as I am using the kernel you had suggested yesterday the latest revision on that branch

<mripard> oliv3r: I do, but I almost never update it :)
<mripard> so, I don't know :)
<Turl> oliv3r: my A20 hardware is still on the post office :"(
<eagles0513875_> n01: via the serial port?
<oliv3r> Turl: you have none yet? :(
<n01> ??
<mripard> Turl: tsss, only excuses for not contributing patches, I'm sure :)
<oliv3r> 587 unread! whoot, progress
<Turl> mripard: heh
<Turl> mripard: did mike get around to merging any of it? :P
<boycottg00gle> oha now hdmi works again
<boycottg00gle> lol
<mripard> no idea :)
<Turl> mripard: we got a lot of clock patches this cycle, maybe we should've arranged to make a pull request instead
<mripard> there's 6 patches for him to pick up
<eagles0513875_> :) ok got it n01
<eagles0513875_> n01: hold on that link is screwy
<Turl> mripard: just 6? I thought they would be like 15 heh
<mripard> and the point isn't really the point. We never ever got a review from him in the first place on these patches
<mripard> well, 6 for the A10s, A20 and A31 patches yes
<mripard> plus your RFC ones
<Turl> yeah
<Turl> mripard: that reminds me, is your a20 clk branch up to date?
<mripard> I think so yes
\\Mr_C\\ has joined #linux-sunxi
<oliv3r> a20-clocks does work fine
<Turl> mripard: looking at clk-next, it seems we got all the __initconst notations wrong
<mripard> ?
<boycottg00gle> after updating uboot from 645e9015 to a3cca421 boot still works but hdmi is off again (seems like hdmi working / not working is quite random)
<mripard> Turl: ah, it's not really that important then
<mripard> but yeah, we should fix it
<Turl> mripard: I can add a patch to my series fixing all of them after the fact
<Turl> mripard: or we can respin all the not yet merged series to get it right there and then fix the remaining cases
<mripard> I'll need to do some tweaks on those init sections as well for other drivers, so whatever you prefer
<mripard> seriously, for that kind of stuff, I'd really like not to respin a new serie and get to the end of the to-merge list once again.
<Turl> mripard: ok then, let's fix all of it after the fact
<Turl> mripard: I'll handle clocks and you handle the other drivers
<mripard> especially since the ARM merge window is almost closed by now, and neither the pinctrl or clocks patches are merged for no reason (yet).
<Turl> linusw hasn't merged them yet? odd
<Turl> mripard: neither is watchdog nor sid :/
<eagles0513875_> n01:
<eagles0513875_> not sure where those odd characters are coming from
<boycottg00gle> oliv3r: for me 218f6438 works
<mripard> Turl: for sid, we had some reasons
<mripard> for watchdog, the maintainer seems to be MIA
<mripard> if we miss 3.12, I'll carry it without his Acked-By in my branch
<boycottg00gle> regression somewhere between 218f6438 or c4163747 and 48845ec7 ?
<n01> eagles0513875_: I think uboot is not reading from sd
<eagles0513875_> n01: where is it trying to read from?
<n01> how do you create that card
<eagles0513875_> i let the script here sudo ./ ../../../output/images/ /dev/sdb format and put the stuff it needs on the card
<oliv3r> boycottg00gle: i'm just confused on how to check what changed inbetween, but that's my lack of git-foo
<eagles0513875_> n01: will paste you whats in the script
<n01> yep that is my script and it works for cubie1
<eagles0513875_> ok
<eagles0513875_> whats next in the recipe change
<oliv3r> boycottg00gle: is that working on a20?
<n01> eagles0513875_: stop into uboot and give the commands one by one
<boycottg00gle> oliv3r: using emacs/magit myself most of the time (ymmv)
<oliv3r> <- vim!
<boycottg00gle> oliv3r: working on olimex a20
<eagles0513875_> n01: you mean dont let it autoboot
<oliv3r> boycottg00gle: hmm, strange, because taht's before the merge
<n01> yes
<oliv3r> boycottg00gle: so it breaks in the last 2 patches?
<boycottg00gle> oliv3r: no for me the old/sunxi-current works

<oliv3r> i'll keep an eye out ;)

<bfree> anyone familiar with the kernel/initrd/dtb addresses care to look at and see if they can figure out why it would hang there? grub was ext4loaded to 0x4600000 and set to put itself at 0x4800000 and works fine until it tries to boot at which point grubs debug=all leaves hanging at that point in the paste (I'm compiling an earlyprintk kernel atm to see if that shines any light)

<steev> grub?
<steev> uboot is the bootloader, why are you adding in grub?
<bfree> cause it's nicer (a usable menu, updatable config file, doesn't need kernels+initrds processed by mkimage, etc etc), cause I can (try), cause it's new(ish) and "just for fun". it sits on top of uboot

<oliv3r> 2013.07-07802-g218f643 works, confirmed
<bfree> earlyprintk just gets me "Uncompressing Linux... done, booting the kernel." :-/
<bfree> $grubdev guess is: "possibly your platform needs exporting of info about e.g. memory map (most likely) ... GRUB already has memory map. You need to pass it. It may be a variable in device-tree to set or it may be an additional command line argument." ... anyone have any ideas what that might be/mean/need?
jemk has quit [Ping timeout: 264 seconds]
<mripard> bfree: how did you enable earlyprintk?
<mripard> (plus, you should take a look at barebox if you want something nicer than u-boot :))
<bfree> I stole the config from prior debian kernel, make oldconfig, make menuconfig, enabled LL and earlyprintk and set it to sunxi uart0
<mripard> that should be right
<mripard> you have to pass earlyprintk in the bootargs as well though
<bfree> yep I did (otherwise I wouldn't have seen the "Uncompressing Linux... done, booting the kernel." unless I'm missing something, I wasn't seeing it before)
<oliv3r> earlyprintk is set in bootargs i think by default (via u-boot that is)
<mripard> he is not using u-boot
<bfree> well grub on top of u-boot ... grubs arm-uboot platform
<oliv3r> well then yer own your own bud!

<bfree> as it leverages u-boot it's not really competition ;)
<mripard> bfree: grub has no first-stage mechanism on ARM?
<bfree> mripard: corrent, it uses u-boot API
<mripard> so, for now, you have U-Boot SPL -> U-Boot -> Grub -> Linux, right?
<bfree> mripard: correct
* mripard wonders if the new U-boot Falcon Mode could be used
<mripard> that would be cool :)
<bfree> it's only recently merged to grub trunk having been around a while as a branch. I don't think they'd any interest in re-inventing all the board support from scratch ;)
<oliv3r> falcon mode?
<oliv3r> mripard: oh i'm not against it at all :p
<mripard> oliv3r: only the SPL starting the kernel
<oliv3r> dunno if possible
<mripard> if it is possible to do what ?
hramrach has joined #linux-sunxi
<oliv3r> spl is really small, 24k only
<oliv3r> and i think it needs to do more then just load the kernel?
<oliv3r> well, it inits dram; it loads 'a file to dram' and executes it
<oliv3r> so maybe it could be possible
<oliv3r> hno: ^

<oliv3r> how can i apply have a commit?

<oliv3r> iw ant to test only parts of a patch
<oliv3r> commit*
<mripard> apply it, and play with stash/checkout -p ?
<oliv3r> checkout -p? is that like add -p?
<mripard> yes
<mripard> but the other way around
<mripard> you discard bits of a patch, instead of adding them
<oliv3r> so i checkout badhash-1; then checkout -p badhash
<bfree> mripard: does the above bit about passing the memory map mean anything to you? I'm drawing a blank :-/ I wondering if it means grub needs to do more updating of the dtb (perhaps the nodes it wants to update aren't there): (from line 60)

<xtofury> hey turl, if you're around, thanks for that tip about make mrproper....
<xtofury> it's weird I had the dependencies installed, but when I went to deal with make menuconfig, getting the 64 bit libraries for libncurses5 worked, but I noticed it removed libncurses5-dev:i386
<xtofury> so I tried to compile last night clean, and noticed it failed on the packer, missing u-boot.bin, and another bug with boot.fex --> I believe this is because of the removed dependency i386 version. so I put it back on, is there a way to get through this without another 12 hours of compiling to find out?

<hno> actaully it's good... the reason it broke is because MMC have got generic Falcon support now.
<hno> but was not entirely intentional that loading u-boot.bin should break
<oliv3r> about falcon mode, how likly is it that we can boot the kernel using falcon mode on A10/A20?
<hno> but using uImage have always been preferred, just not very visibly so.
<oliv3r> i mean, what does u-boot do now, that SPL can't do?
<hno> oliv3r, from what I understand it should just work.
<hno> but have not looked in detail.
<hno> but only for mainline. there is no script.bin Falcon support..
<oliv3r> so we handle everything required in our 24k allready?
<oliv3r> so how would I invoke it (with a mainline kernel?)

<[7]> hno: sorry for contacting you directly with this, but I think you're involved with sun4i MTD and boot0/1 replacement work, right?
<[7]> if so, can you give me a quick overview about the status of that work? is it already possible to completely get rid of allwinner's FTL and write a (working) uboot SPL to the raw NAND instead, and use yaffs2 or something from there on?
<[7]> if that's already possible I'd love to check it out and experiment with it :)
<hno> [7] I don't think yaffs2 works yet. oob data is not supported yet, and I do not know if the oob data made available by the Nand ECC controller is sufficient for yaffs2.
<[7]> well, I'd prefer yaffs2 if possible, but would be fine with any flash file system that's faster than this crappy FTL for now
<[7]> that might be one of the areas for me to experiment with :)
<hno> I don't think the speed issues is due to the FTL really..
<[7]> interesting... I'd want to experiment with it regardless. this proprietary allwinner stuff is just annoying me
<[7]> (and I've just experienced filesystem corruption while using it)
fredy has joined #linux-sunxi
<[7]> so can this be done already? if so, which git branches (or patches?) would I need to use?
<[7]> (also what's the matter with OOB data? which data does the nand ECC controller "make available"? do you mean that the ECC controller is putting the checksums at a specific position within the OOB bytes where it might conflict with other stuff?)
<hno> The Nand controlle rhave hardware ECC + Randomizer support, and as such manages the OOB data area as well.
<hno> There is support for "user data" in the ECC area, but I am not sure how much is made available. But I am sure it is no more than 32 bit per 1K data.
<[7]> ouch, that's small
<[7]> probably too small for yaffs2 indeed. do other flash filesystems require less space there?
<[7]> it's also kinda odd because it seems to be incompatible with the way how flash memory manufacturers typically mark factory-known bad blocks?
<hno> UBI don't use OOB at all.

<hno> bad block management is a chapter on it's own. OOB bad block markers is only meant to be used on initial (format time) scan of the NAND. After that the driver is supposed to maintain it's own tables.
<[7]> ...which would screw up that information in case it is ever reformatted?
<[7]> both yaffs2 and the Whimory FTL that I've worked with kept that byte as is, assuming anything other than 0xff means bad, and writing an implementation-specific value to own discovered bad blocks
<hno> To access (read) raw OOB data the ECC + randomizer is disabled. This is also needed to detect blank pages. But as above, once formatted the driver really should not need to do this.

<hno> Doing a complete reformad of a Nand is generally a bad idea. You want to preserve erase counters and some other data.
<[7]> for file systems which even have those (yaffs2 doesn't). and I fully agree for FTLs, as long as nothing got corrupted.
<[7]> ok, so assuming I go with UBI... what is necessary to get that set up?

<hno> [7] you need the mtb branch of kernel & u-boot.
<[7]> of which repositories?
<[7]> doesn't seem to exist in linux-sunxi/linux-sunxi, so I guess I need a special one?
<hno> Looking that up...
<hno> [7] See "A10 MTD NAND driver update - let's say goodbye to LiveSuit" thead on the mailinlist.
<[7]> ok, thanks for the information :)
<oliv3r> [7]: there was some recent chatter on the mailing list about the mtd stuff btw
<hno> yes... apparently yuq have some trouble making proper use of the randomizer.

<tlhingan> Need help with an A20
<Turl> wingrime: you can improve google's map with the mapmaker tool too
<tlhingan> Need to rotate the LCD display and it's not supported by the driver
<tlhingan> xrandr depends entirely on the driver, doesn't it?

<Turl> tlhingan: have you tried echo 2 > /sys/class/graphics/fb0/rotate ?
<Turl> it should rotate it 180º
hramrach has joined #linux-sunxi
<tlhingan> It didn't
<ssvb> tlhingan, Turl: afaik the display controller hardware does not support rotation (but this can be done with G2D and I believe android uses it)
<Turl> ssvb: I thought it'd have a sw fallback :(
<ssvb> with fbdev driver it is possible to use Option "Rotate" for software rotation
<ssvb> tlhingan: you can check "man fbdev"
ZetaNeta has joined #linux-sunxi
<tlhingan> reading man fbdev
<tlhingan> xrandr can't do it
