Hi folks! I'm trying to get Mali (for framebuffer) working on A20 (Olimex). Using the sunxi-3.4 branch and latest mali-tools (and latest mali-proprietary) but no matter what I do, the 'test' tool just returns "eglInitialize failed".

Hi everyone, quick question, I am running Fedora 19 (A20) on my cubieboard2, and I am trying to work with GPIO. Unfortunately it seems that i am missing the gpio module... is can see modules for sun4i & sun5i but not for sun7i.
<Guest51186>
is this module available yet ? if yes, what is there a way that I can only compile this missing module ?
<nedko>
fralle_: i think i saw code to read boot.axf in the android (sdk?) code
<nedko>
there were some comments in chineese

downloading sunxi-bsp and building got me boot0.bin boot1.bin and all other files
<fralle_>
but im not sure how to continue know
<fralle_>
:)
<Turl>
if you want to boot uboot directly you need to use a sd card
<Turl>
if you want to use nand you need to keep on using the boot0+boot1 stack
<fralle_>
Turl, where do i put boot0&1 in nand?
<fralle_>
or how
<fralle_>
is it a must to either use fel mode?

:)
<Turl>
fralle_: dunno what your device is
<fralle_>
a10
<Turl>
fralle_: yeah but what?
<Turl>
A10 is just the SoC
<fralle_>
from uboot: Board: A10_MID_1GB
<fralle_>
CPU: Allwinner A10 (SUN4I)
<Turl>
fralle_: is it a tablet? have you identified which one?
<Turl>
you can google for a stock rom image for it and flash with livesuit
<fralle_>
ok ill try :)

I'm getting IO errors when trying to compile the kernel. Anyone have any ideas? http://pastebin.com/SCPW3Jqw mmcblk0: timed out sending r/w cmd command, card status 0x900

kenny: you compile kernel on sdcard?
<kenny>
NermaN: I was trying to, yes
shineworld has quit [Quit: Leaving]
<NermaN>
kenny: seems like sdcard died, they do it very fast on writing
<kenny>
this happened with both a 3.4 kernel and a 3.14-rc1 kernel. I ran an 'fsck -c' on another machine and it didn't find any issues
<kenny>
the card is 64G and has never had even that amount of data written to it
<rm>
SD cards can die in a lot of bizzare ways

Maybe, I'm not yet convinced it's the SD card though. I ran badblocks manually and it could read/write a random pattern perfectly fine (again from a desktop machine)

<hramrach>
kenny: I have been compiling on a SD card without issues in the past so your card is probably special
<hramrach>
isn't 64GB sdxc? You are probably the first to test that. Note that the manufacturer spec for all boards says max is 32GB although the controller seems sdxc capable

and I don't see any probe messages related to consoles being initialized

so it looks to me that the driver is not enabled
<NermaN>
Turl: thanks will try now
<ccaione>
I don't get ... sata?
<ccaione>
Turl: weird, sunxi_defconfig should be ok
<ccaione>
that's why I suspect something rootfs wise

ccaione: as oliv3r said sata driver is ready
hawi has joined #linux-sunxi

Turl: me :)
<ccaione>
it does its dirty job
<ccaione>
g2g, bbl
<mnemoc>
it would be awesome if sunxi-next and sunxi-devel would have a less spartan defconfig, to increase the usefulness of the nightly builds
<alexvf>
any expert on a20 display engine?
<mnemoc>
ssvb and libv
<alexvf>
thanks

merbanan: I second that. Even something on the wiki listing what drivers are needed for what would be useful (to me)

bbrezillon has quit [Quit: Ex-Chat]
<ssvb>
alexvf: I don't think so, alpha blending is only done once in the pipeline
<ssvb>
alexvf: are you reading the a20 user manual?
<alexvf>
ssvb: i think i read a pdf document explainig DEFE and DEBE
<ssvb>
ok
<alexvf>
ssvb: but nothing to get the hands on it
<ssvb>
what are you trying to do with 3 layers?
<alexvf>
ssvb: so i was trying to draw over the mplayer osd branch, which draws in two layers if i understood the code
<alexvf>
i was trying to draw an user interface over mplayer
<alexvf>
i could get along with the no-osd branch but it lacks subtitle support, the other osd features are not big loss for me

i'm use my cubieboard as router, and not it booted on new kernel
<NermaN>
there was one strange issue - rootfs was mounted RO
<Turl>
mnemoc: multi_v7_defconfig :)
<Turl>
NermaN: glad it works :)
<NermaN>
strange thing that load average was always > 1 is finally fixed
<mnemoc>
Turl: can you submit the diffs as a patch to hansg so sunxi-devel becomes user-friendly?
<Turl>
mnemoc: hm? we already have multi_v7_defconfig :)
<mnemoc>
Turl: but that's not useful for the nightlies
<mnemoc>
the idea of the nightlies is 1) test-build everything sunxi related, 2) provide something people can use to help testing without having to compile their own
<mnemoc>
if the sunxi_defconfig is too spartan it doesn't help at all to make the builds
<mnemoc>
and specially sunxi-devel and sunxi-next need testers
<Turl>
it could use some patches to turn on sata and the other things staging there though
