02:18 <ajayr_> hello I am playing with hste's images for ubuntu and have a few problems, can anyone here help?

02:23 <ajayr> basically it never loads and runs ubootcmd

02:23 <ajayr> I am using kernel_reverted and am trying to set the screen resolution in bootcmd

02:24 <ajayr> after that next I want to make the OS run from mmc1 so that I can debug when kernel fails

02:25 <ajayr> for that I stuck a old 128MB microsd containing only the u-boot.imx in the internal and

02:25 <ajayr> all the os kernel and stuff in the external sd

02:25 <abrasive> how are you assembling your bootcmd?

02:25 <ajayr> 1 u-boot does not know how to look in external mmc1:1 for ubootcmd

02:26 <ajayr> edit with vi and mkimage on host

02:26 <ajayr> stick sd into 802

02:26 <abrasive> it only looks for ext2 partitions.

02:26 <ajayr> ahh abrasive ... i have something for you hang on let me pastebin it

02:27 <ajayr> http://paste.fedoraproject.org/6396/64783251

02:28 <abrasive> thanks.

02:28 <ajayr> the last line ext2load mmc ${mmcdev} needs a partition spec right?

02:28 <abrasive> source doesn't need ${loadaddr}

02:28 <abrasive> it defaults to CONFIG_SYS_LOAD_ADDR

02:28 <abrasive> which is loadaddr

02:29 <ajayr> just look at cubox I am coming from that ...

02:29 <ajayr> http://www.solid-run.com/phpbb/viewtopic.php?f=7&t=1109

02:30 <ajayr> we do load from usb mmc ide in order on the cubox let me find the exact snippet on github

02:31 <ajayr> https://github.com/rabeeh/u-boot/blob/master/board/marvell/mv_dove/mv_main.c

02:32 <ajayr> line 700 onwards

02:33 <ajayr> then does the kernel overwrite the same mem addr when it loads? shouldnt the script load somewhere else?

02:33 <ajayr> I have finally instrumented the gk802 with serial I will keep banging at it today till i work it out

02:36 <abrasive> my understanding is that the current arrangement does work/

02:37 <ajayr> ok I will upload a serial log and we can look at that ..

02:43 <ajayr> the bootargs in env set 1280 and in bootcmd 1920 video res

02:47 <abrasive> video has to be set from env

02:47 <abrasive> can't be reconfigured after init.

02:49 wumpus has quit [*.net *.split]

02:49 <ajayr> ok the really big thing for me is .. boot and run from ext sd, since I will try fedora-18 headless on this

02:50 <ajayr> once the video stuff is woked ou I can get around to that

02:52 <ajayr> i just rebooted and the damn thing did not look at bootcmd!!! does a warm reboot and power on reboot work differently?

02:55 <ajayr> http://paste.fedoraproject.org/6399/47849111 with reboot at console ...

02:55 <ajayr> and http://paste.fedoraproject.org/6400/78491713 with power on reset ...

02:58 <ajayr> any pointers for a 3.8 kernel for fedora? will mainline just work? like the cubox or is there any other tree to try? afaik fedora uses systemd and that will not boot on 3.0.35 must use 3.6+ for that

03:00 <abrasive> systemd works fine on 3.0.35.

03:00 <abrasive> at least my arch install uses it, from memory.

03:02 <ajayr> is that hard or soft float?

03:04 <ajayr> fedora is pretty aggressive in its requirements the kernel needs a whole bunch of stuff and then you must use a initrd to load so its a lot of work to get it workiing on a unsupported platform ...

03:05 <ajayr> from the top of my head stuff like selinux, audit, devtmpfs, ipv6 and then there must be more ...

03:06 <ajayr> but what the hell I have a gk802 to hack and the kids have the other hooked to the tv running android!

03:06 <ajayr> unfortunately the ambient temp is 34deg C and the gk802 hits upto 90deg very very fast

03:07 <ajayr> cat /sys/devices/virtual/thermal/thermal_zone0/temp

03:07 <ajayr> 50

03:08 <ajayr> cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

03:08 <ajayr> 396000

03:09 <abrasive> does it? that's no good.

03:10 <abrasive> is it properly heatsunk to the case?

03:12 <ajayr> mgyver does it ... its open and a P4 Nehalem style cpu heatsink is just kept on it ...

03:13 <ajayr> serial consol is wired up and i keep fiddling with the internal sd since until now i did not have it reliably booting from exernal sd

03:14 <abrasive> fair enough.

03:14 <abrasive> i put mine back together with the serial wires out the side and no internal card.

03:14 <abrasive> since one can boot u-boot over USB

09:53 <jorgegeorge> sorry for the mistype by "up arrow"

10:07 <wumpus> btw has anyone yet managed to get rid of the 'need to press a key at boot' thing?

10:08 <abrasive> wumpus: i haven't observed that recently on my system

10:08 <wumpus> I'm using my gk802 as network device, so it's pretty annoying

10:08 <wumpus> I suppose it's something with either the kernel or the userspace

10:08 <wumpus> maybe some new image solved it?

10:08 <abrasive> halting when it shouldn't / waiting for an interrupt

10:09 <abrasive> i've been using the same Arch armhf userland since i started.

10:09 <wumpus> okay

10:09 <wumpus> I'll try building a new kernel then

10:10 <wumpus> thanks

10:37 <wumpus> which branch should I take for gk802, imx_3.0.35_1.1.0-hdmidongle or imx_3.0.35_1.1.0-hdmidongle-jas?

10:40 <wumpus> seems the former is more recent

10:43 <wumpus> ah I was still using the wrong repo

10:44 <hste> imx_3.0.35_1.1.0-hdmidongle and imx6_hdmidongle_defconfig works for me

10:46 <wumpus> shouldnt that be imx6_gk802_defconfig ?

10:46 <hste> thats jas version. both should work

10:47 <wumpus> okay

15:30 <jorgegeorge> I played a bit with the GK802 std Android. Looks like it's using Bluez as well. I can scan (sees devices) but pair is not working for any of the scanned devices.

15:30 <jorgegeorge> Looking to the serial console, looks like Android does come tricks on coexistence as in the lines "BT Coexistance = disable" , "rtw_android_priv_cmd: Android private cmd "BTCOEXSCAN-STOP" on wlan0", "rtw_android_priv_cmd: Android private cmd "BTCOEXMODE 1" on wlan", "rtw_android_priv_cmd: Android private cmd "BTCOEXMODE 2" on wlan0"

15:30 <jorgegeorge> So I think will not be easy to have BT working at the same time as WiFi on Linux

15:48 <hste> rz2k: how is it going with your wandboard?

15:49 <rz2k> going to get more modules from technexion

15:49 <rz2k> my boss decided to go CoM with EDM1 standard

15:49 <rz2k> technexion is menufacturer of wandboard

15:50 <hste> cnxsoft had some info on his page, and a link to http://repo.or.cz/w/wandboard.git

16:32 <otavio> Hello

16:34 <otavio> I am waiting for the dongles to arrive for me but I found the information about the group and I'd like to offer help in adding support for it in Yocto

16:34 <otavio> Anyone interested?

16:38 DieMumie1 has joined #imx6-dongle

16:40 <hste> otavio: yes yocto seems nice. I know someone have tried it

16:40 DieMumiee has quit [Ping timeout: 256 seconds]

17:20 <otavio> hste: Right; I can be of help. I am the maintainer of meta-fsl-arm so I think I can deal with it

17:20 <otavio> hste: the dongles did not yet arrive for me

17:20 <otavio> hste: but should soon

17:26 <hste> otavio: would it be possible to build hardfp with yocto?

17:26 <otavio> hste: sure; quite easy

17:26 <otavio> hste: the main problem now is vivante binaries in hardfp

17:27 <hste> hste: or softfp....

17:28 jorgegeorge has quit [Remote host closed the connection]

17:28 <hste> otavio: how is it to set up new packages into a yocto system. Like lxde and firefox?

17:29 DieMumiee has joined #imx6-dongle

17:37 <otavio> hste: easy; we have chromium and firefox ready for use

17:37 <otavio> hste: lxde I don't recall if it is packaged but it is not hard

17:37 <otavio> hste: much easier then LTIB

17:37 <otavio> ;)

17:43 <hste> otavio: I saw freescale was going to support it soon too.

17:47 jas-hacks_ has joined #imx6-dongle

17:47 <otavio> hste: we hope so

17:47 <otavio> hste: some information I cannot disclose as I am under NDA

17:47 <otavio> hste: but I can help

17:49 <hste> otavio: :)

17:52 <jas-hacks_> octavio: Is it possible to build the vivante driver against xorg 10.4 but using the 1.1.0 binaries?

17:54 allanmac has quit [Remote host closed the connection]

17:57 <jas-hacks_> otavio: Can I change the xorg-xserver receipe to pull down 1.10.4?

17:58 <otavio> jas-hacks_: I have it ready for sending later today; with 1.11.4 Xorg

17:58 <otavio> jas-hacks_: which works just fine

17:58 <otavio> Have someone worked in adding the dongle in U-Boot mainline?

17:59 <jas-hacks_> We have our own git repo for our changes

18:02 <jas-hacks_> otavio: Is there a receipe for building dri-xorg-graphic-imx-viv-12.09.01?

18:06 <hste> otavio: we have not got support from the hw-vendor of the dongle..... abrasive, jas and rz2k did a great job on getting uboot and kernel working. Putting together pieces from sources found around on gits etc

18:06 <otavio> jas-hacks_: yes

18:07 <otavio> hste: yes so we may try to get in touch with those guys

18:07 <jas-hacks_> otavio: Can't find it, where is it in the source tree?

18:07 <otavio> jas-hacks_: I will try to find something

18:08 <otavio> jas-hacks_: ahh

18:08 <otavio> jas-hacks_: what you're looking for?

18:08 <jas-hacks_> otavio: dri-xorg-graphic-imx-viv

18:09 <otavio> jas-hacks_: ah

18:09 <otavio> jas-hacks_: http://git.yoctoproject.org/cgit/cgit.cgi/meta-fsl-arm/tree/recipes-graphics/xorg-driver/xf86-dri-vivante_12.09.01.bb

18:12 <jas-hacks_> otavio: Thanks , couldn't see it even though it was staring me in the face ;).

18:12 <rz2k> <otavio> Have someone worked in adding the dongle in U-Boot mainline? - that is overkill for some chinese device that small group of users have

18:12 <rz2k> but if you feel like it - you can grab our changes

18:13 <otavio> rz2k: once I get the dongle, I will

18:13 <rz2k> thanks

18:13 <otavio> rz2k: I hate to use FSL U-Boot

18:13 <otavio> rz2k: too old and broken ;-)

18:14 <rz2k> somewhare up the logs I posted a link to freescale's git where they collect patches for u-boot mainline

18:16 <otavio> rz2k: In github?

18:16 <otavio> rz2k: I am the admin of it ;-)

18:16 <rz2k> yes, freescale github

18:16 <rz2k> lol, sorry then.

18:16 <otavio> rz2k: Fabio and I been working at maintaining a branch supporting mainline

18:16 <otavio> rz2k: lol no problem

18:17 <jas-hacks_> otavio: Is gpu-viv-bin-mx6q_1.1.0.bb backward compatible with older xserver, say 1.10.4?

18:17 <otavio> rz2k: We're now adding support to SoloLite and Dual board

18:17 <otavio> jas-hacks_: yes

18:17 <otavio> jas-hacks_: but not compatible with > 1.13

18:17 <otavio> rz2k: you guys have add a usb loader in GIT for U-Boot

18:18 <otavio> rz2k: but Boundary has a tool which is generic

18:18 <rz2k> yes, it was written by abrasive with use of datasheets

18:18 <rz2k> its basic as hell :p

18:18 <otavio> rz2k: not need to duplicate it as it has a generic one done by Bondary which should work just fine

18:20 <rz2k> otavio: also just in case if you are working with freescale more than u-boot level, this month I will try to make use of VPU, I need decode and encode of VP8 at same time, we are building telepresense system

18:20 <rz2k> right now it is working on exynos4412

18:20 <rz2k> in software decode ://

18:20 <otavio> rz2k: you can use the gst plugins for it I think

18:20 <rz2k> so, does imx6 have common pitfails there?

18:20 <otavio> rz2k: all packaged in Yocto ;-)

18:21 <rz2k> never worked with gst, I fear that scaling the frame to window will be a problem (it was on allwinner a10, it was dumped away and changed to exynos)

18:22 <jas-hacks_> otavio: How can I force a rebuild of a recipe and then all its dependencies?

18:24 <otavio> jas-hacks_: what do you mean?

18:25 <otavio> rz2k: so how do you plan to do that?

18:26 <jas-hacks_> otavio: After a full build, if I change a recipe file, yocto is reporting no changes hence no build.

18:26 <otavio> jas-hacks_: danny or master?

18:26 <jas-hacks_> otavio: master

18:26 <otavio> jas-hacks_: you may use the PRServer

18:26 <otavio> jas-hacks_: check local.conf.sample.extended

18:29 <rz2k> otavio: will check if vpu/ipu/vdoa can scale frames, if they can, it will be done software, but atleast encoding/decoding should work without hardcore cpu burn

18:41 eebrah has joined #imx6-dongle

18:42 <rz2k> otavio: he means the composite extensions and etc. which should be built on xorg build

18:42 <otavio> rz2k: separated things

18:42 <otavio> jas-hacks_: Xorg build some

18:43 <otavio> jas-hacks_: dri builds dri only

18:43 <otavio> jas-hacks_: video-fbdev-vivante builds vivante driver

18:44 <jas-hacks_> otavio: I'm trying to work out the vivante components (libs) needed to deploy against a ubuntu rootfs. There seems to the 2 pieces which are xf86-dri-vivante and xf86-video-imxfb-vivante. I assume both are need?

18:49 <otavio> jas-hacks_: yes both

20:20 <otavio> jas-hacks_: but you can rename it as you wish

20:20 <otavio> jas-hacks_: but change the code to load this name

20:21 <jas-hacks_> otavio: I tried Yocto, worked on GK082.

20:21 <otavio> jas-hacks_: so please prepare the patches and send them :-)

20:23 <jas-hacks_> otavio: Mine the was the quick and dirty solution ;(, build Yocto for sabresd then replace uboot + kernel.

20:25 <otavio> jas-hacks_: I will do it clean when I get the dongles here

20:26 <jas-hacks_> otavio: Are freescale using yocto?

20:27 <otavio> jas-hacks_: NDA :)

20:27 <otavio> jas-hacks_: some people are; this is the more I can tell

20:29 allanmac has joined #imx6-dongle

20:29 <hste> I guess they will support in not to far future :)

20:32 <hste> the old system is hard to maintain and build. Yocto looks more up to date

20:34 drachensun has joined #imx6-dongle

20:36 <hste> jas-hacks_: do u know what x version precise is using?

20:38 <otavio> hste: :-)

20:38 <jas-hacks_> hste: its 1.11.3.

20:38 <otavio> hste: your feeling seems to be in the right direction ;-)

20:39 <jas-hacks_> hste: I've compiled the vivante driver(s) and Xorg log reports it loading ok.

20:41 <jas-hacks_> hste: Problem is that gl/egl is causing 100% cpu.

20:43 <hste> jas-hacks_: and it looks like its using the right libs?

20:46 <jas-hacks_> hste: ... I think so

20:48 <hste> jas-hacks_: tried -logverbose 3 in xorg.conf?

20:49 <hste> jas-hacks_: tried -logverbose or higher 3 is default

20:57 <jas-hacks_> hste: doesn't like -logverbose option

21:13 <hste> jas-hacks_: strace -p on the pid for X
