00:01 <emx> there is a lot of env to print...

00:01 <emx> but i can't see my arguments

00:02 <ssvb> well, they should be loaded from script.bin or uEnv.txt

00:03 <ssvb> on what partition do you have these files btw?

00:03 madmaxx has quit [Remote host closed the connection]

00:04 <emx> on the only one

00:04 <emx> in /boot

00:05 <ssvb> which guide did you use when partitioning your sd card?

00:06 madmaxx has joined #cubieboard

00:06 madmaxx has quit [Changing host]

00:06 <emx> err, this one: https://github.com/StephanvanSchaik/gentoo-on-arm/blob/master/cubieboard2/gentoo.md

00:06 <emx> with some tweaks :]

00:07 <ssvb> the usual setup is the first fat partition and the second - something like ext4

00:08 <ssvb> the first fat partition is usually used for the uImage, boot.scr and the other things

00:08 <ssvb> that's why you see something like "fatload mmc 0 0x48000000 uImage" in that guide

00:08 <ssvb> where is your kernel currently?

00:08 <emx> in /boot

00:09 <emx> strange, since the partition mounted to boot, in that guide, is ext2.

00:09 <ssvb> is it being loaded successfully?

00:09 <emx> i can boot into gentoo. so i guess: yes.

00:10 <ssvb> are you sure it is really loaded from /boot?

00:11 <ssvb> what happens if you temporarily remove the kernel from boot, will it stop booting?

00:11 <emx> ssvb, i don't know any alternative. what i still got is android on nand.

00:11 <emx> i try

00:12 <ssvb> the u-boot messages on the serial console can also help to understand what's going on

00:15 <emx> the screen stays quiet and there is no heartbeat.

00:15 Baronawesome has quit [Ping timeout: 240 seconds]

00:15 <ssvb> ok

00:16 <ssvb> except that I don't quite understand how you can have your rootfs on /dev/mmcblk0p1

00:16 <ssvb> do you have two partitions on the sd card?

00:16 <emx> no, just one

00:16 <ssvb> why?

00:17 <emx> i'm used to

00:17 <ssvb> I guess this explains all kind of troubles

00:17 Vanfanel has quit [Quit: Lost terminal]

00:18 <emx> hfmpflbm

00:18 <ssvb> but I'm impressed that u-boot manages to find your kernel in the /boot subdirectory of your only partition

00:18 <emx> except why firefox doesn't compile, maybe.

00:18 <emx> well, there was something with "if .. /boot/"

00:18 <emx> so u-boot is aware of that directory.

00:19 <ssvb> yes, that's why I suggested to check 'printenv'

00:19 <ssvb> what does it say about boot.scr or uEnv.txt?

00:20 <ssvb> does it also look it up in /boot?

00:22 Baronawesome has joined #cubieboard

00:23 <emx> i try to figure it out

00:23 <ssvb> ok

00:23 <emx> how can i update groups in a terminal?

00:23 <ssvb> groups?

00:23 <emx> i added myself to dialout

00:24 <emx> but it only has effect when i choose a console with alt-f2, e.g., and log in.

00:27 <ssvb> afaik you need to re-login for these changes to take effect

00:27 <ssvb> or you can try something like 'su - your_username' in the terminal

00:31 <Thihi> http://cryptome.org/2013/12/turing-pardon.pdf :3

00:31 <emx> ok. i got serial on X now

00:34 rellla has quit [Ping timeout: 260 seconds]

00:37 <emx> ssvb, setenv is accepted but fatload [..] tells me "unrecognised filesystem type". what a surprise.

00:38 <ssvb> lol :)

00:39 <ssvb> but I guess it might have picked the cmdline already and the fatload commands are not necessary

00:41 <ssvb> or read 'help' in u-boot and find a suitable replacement for the 'fatload' command, which would work with ext filesystem instead

00:42 <ssvb> basically, if you are deliberately deviating from the instructions, then it is assumed that you perfectly understand the boot process and how to make various things connect to each other correctly :)

00:48 <emx> ssvb, yes. so far i can tell that substituting fatload by ext4load and using absolute paths for uImage doesn't help :P

00:48 <emx> the system boots but openrc doesn't start. i have to investigate tomorrow.

10:57 <Vanfanel> ssvb: sorry to bother you again, but I really can't fix the "framebuffer stall" error upon exiting my EGL code. As I told you (and you saw in the code) I CAN clear the framebuffer on exit, but it doesn't always work

10:57 <Vanfanel> most of the times, the last EGL/GLES frame stays on top

10:58 <Vanfanel> ssvb: so, if the last EGL/GLES frame stays on top, there's no use in clearing the framebuffer contents on exit

10:58 <Vanfanel> ssvb: any solution to this problem, please?

17:56 <emx> ssvb, hi. magically, i managed to have 1080p output.

17:56 <emx> what i am interested in now is: how can i play 1080p movies?

17:56 <emx> i got a 720p one and it is unviewable.

17:58 <mnemoc> because you are doing it software accelerated

17:58 kivutar has quit [Ping timeout: 240 seconds]

17:59 <emx> mnemoc, so how do i do it the hard way?

17:59 <emx> (got the pun? %))

17:59 <mnemoc> https://github.com/linux-sunxi/libvdpau-sunxi

17:59 <ssvb> emx: congrats, I guess you have learned a lot of new interesting things in the process :)

18:00 <ssvb> emx: setting up the hardware accelerated video decoding is also quite entertaining

18:00 <emx> ssvb, well, it is limited since grub has a cmd line, too (and i used it a lot) :P

18:00 <emx> ssvb, i got time for that ^^

18:01 <emx> mnemoc, i use gentoo and the vdpau useflag is disabled. will that driver work despite that fact?

18:02 <ssvb> emx: you just need to unmask the vdpau use flag

18:02 <emx> i can unmask it? how great is that? never heard of that. i try right away.

18:03 <ssvb> emx: and we should file a bug in gentoo bugtracker, explaining that vdpau is also relevant for arm systems :)

18:04 <emx> ssvb, actually we should convince the gentoo team to develop for arm only from now on :D

18:04 <ssvb> emx: just add "-vdpau" into your /etc/portage/profile/use.mask (or create this file if it does not exist)

18:05 <emx> ssvb, do you mean profile or make.profile?

18:05 <emx> profile you mean

18:05 <ssvb> emx: and also use the ~arm keyworded versions of ffmpeg and mplayer (the stable versions don't have h264 support for vdpau yet)

18:06 <ssvb> emx: I mean the file name exactly as it is written

18:08 <emx> does anyone have the acryl case for cubieboard1/2?

18:09 <ssvb> emx: you can also check "man portage"

18:10 <emx> or use a search engine.

18:11 <emx> i guess the last big challenge will be how to compile firefox :-/

18:20 <wolfy> emx: I have the white/black box that comes with cubie2

18:22 <emx> wolfy, i mean this one: http://www.axiris.eu/en/index.php/enclosures/case-for-cubieboard

18:22 <wolfy> nope, i have a diff. one

18:22 <emx> ok, thanks anyways.

18:22 <ssvb> wolfy: is the top lid of your box also a little bit flakey?

18:23 <wolfy> flakey no, but it has other issues.

18:23 <wolfy> for instance I cannot use livesuit if the cubie is inside the box

18:23 <wolfy> the USB cable does not make a good contact, only the power lines reach the pins

18:24 <ssvb> wolfy: I have this one - http://store.r0ck.me/products/black-white-case-for-cubieboard

18:25 <wolfy> ssvb: that's the one I have, too

18:25 <ssvb> wolfy: and I had to use a duck tape to make sure that the lid stays in place and does not wobble :)

18:25 <wolfy> i am not surprised

18:25 <wolfy> ps: it's duct, not duck :)

18:26 <ssvb> oops :)

18:26 <emx> lol ssvb. with your intelligence that is quite a primitive fix :P

18:26 <emx> but i guess soon you will 3d print your one case.

18:26 <emx> *own

20:15 <Wizzup> maybe just unstable related

20:15 <Wizzup> try with -vo xv

20:15 <Wizzup> if it is still the same, codec problem in unstable
