Hi, Attached you\\\'ve a GSTreamer package with DSP Support. What\\\'s included in the package: * GST TI plugin. * CMEMK, LPM, DSPlink, SDMAK, configured and compiled for Linux 2.6.33-rc6 * Codec Server compiled and configured for Linux 2.6.33-rc6 * Configuration scripts. Prerequisites: * IGEPv2 board Revision B (600 or 720 Mhz) * Linux Kernel 2.6.33-rc6 (you can download from [url]http://git.myigep.com[/url]) * Gstreamer executable and also others plugins included in gstreamer such avidemux, qtdemux ... How to use: 1) Download the package and untar inside the IGEPv2 rootfs 2) Configure the uboot, MEM linux = 442M (mem=442) 3) Execute loadmodules.sh script included in the package. 4) Execute settings.sh script included in the package. 5) Execute gstreamer for play your favorite film or song or both ;) Example: gst-launch -v filesrc location=../video/big-buck-bunny.mp4 ! qtdemux name=demux demux.audio_00 ! queue max-size-buffers=8000 max-size-time=0 max-size-bytes=0 ! TIAuddec1 ! alsasink demux.video_00 ! queue ! TIViddec2 codecName=mpeg4dec engineName=codecServer ! TIDmaiVideoSink videoStd=720P_60 videoOutput=dvi sync=false displayDevice=/dev/fb1 Codecs avaliable: aac, mp3, h264, mpg4, mpg2 Kind Regards Manel

    What config file did you use for compiling the kernel. The igep one inside arch/arm/configs doesn\\\'t contain support for things like framebuffer and doesn\\\'t have PREEMPT enabled to use with your compiled modules, and the one supplied with the 2.6.28 kernel isn\\\'t compatible. Also anyone using this note that the kernel git is now at rc7 and so you will have to look through the commit logs if you want the correct one. mcaro, I\\\'ve also tried to compile those cmemk etc. modules myself. Did you just use the framework provided by igep, or did you use the TI ones directly?

    Hi, Thanks you for providing this demo, I was really looking forward to see it run... However, I ran into a few problems: Your tgz is for the -rc8 kernel, but your git-tree still is at -rc7. So I tried to simply change the version of my kernel to -rc8, recompile, and the modules did indeed load. Next problem was the video memory, the settings.sh tries to allocate 16MB of video memory for framebuffer1, the kernel default was at 14MB IIRC (option \"CONFIG_OMAP2_VRAM_SIZE\"), which I had to change, too. Then, when both load-modules.sh and settings.sh finished without problems, I tried to run the gstreamer chain (With gstreamer 0.10.24, I hope that was the correct version). But all I got was a kernel oops in the lpm_omap3530 module. Do you think it is a problem with the kernel? Should I wait for the \"real rc8\" to appear in your git repo and retry? And related: cmemk.ko is under GPL, dsplinkk.ko is under GPL V2, lpm_omap3530.ko is under GPL, and sdmak.ko is under GPL, too. Could you simply add those modules to the git.myigep.com \"linux-omap-2.6.git\"- Tree? So we could simply re-compile them ourselves as needed, and wouldn\\\'t have problems with binary-incompatible kernel options, like \"PREEMPT\"... Also the Kconfig for them could verify all required options (Framebuffer settings and the like) are setup correct. Cheers, Ernst

    Hi entropy, Now our git it\\\'s updated to RC8. [quote=""entropy":1jj0u5te":1vcexze6]Your tgz is for the -rc8 kernel, but your git-tree still is at -rc7. So I tried to simply change the version of my kernel to -rc8, recompile, and the modules did indeed load.[/quote] RC6 Modules in special CMEMK and LPM don\\\'t work with RC7 or RC8 kernel versions, due a important changes in ARM Cache ... [quote=""entropy":1jj0u5te":1vcexze6]Next problem was the video memory, the settings.sh tries to allocate 16MB of video memory for framebuffer1, the kernel default was at 14MB IIRC (option "CONFIG_OMAP2_VRAM_SIZE"), which I had to change, too.[/quote] Yes, but it\\\'s only a suggestion you can test with your own configuration ... [quote=""entropy":1jj0u5te":1vcexze6]Do you think it is a problem with the kernel? Should I wait for the "real rc8" to appear in your git repo and retry?[/quote] Yes it\\\'s is ... Now you can download from our git repository. [quote=""entropy":1jj0u5te":1vcexze6]And related: cmemk.ko is under GPL, dsplinkk.ko is under GPL V2, lpm_omap3530.ko is under GPL, and sdmak.ko is under GPL, too. Could you simply add those modules to the git.myigep.com "linux-omap-2.6.git"- Tree?[/quote] It\\\'s not possible :( But I suggest see the source code from these modules for look why ... [quote=""entropy":1jj0u5te":1vcexze6]Also the Kconfig for them could verify all required options (Framebuffer settings and the like) are setup correct.[/quote] In the last version provided we used the default configuration in RC8, but using the default configuration you must change the "disable unused clocks" this option is activated by default and with this option we encounter some problems ...

    I did try again, with the rc8-kernel from your git. I used mostly the igep0020_defconfig, with a few changes (ext4-filesystem, RTC, USB-HID devices, ...) However I still get a NULL-Pointer dereference Kernel-OOPs every time I try to run gstreamer. After using strace on gst-launch, I found I can also reproduce the kernel-OOPs with a simple \"cat /dev/lpm0\" Could you maybe post a working kernel .config, so I can diff against my version? Or could it be a problem with my GCC? I\\\'m running 4.3.4 on gentoo, and am compiling my kernel directly on the IGEP.

    Hi I have some problems with this, When I use TIDmaiVideoSink with videoStd=720P_50 or more, gst-launch exits and I get the following message on the serial debug port: \\\'[ 739.917816] omapfb omapfb: setup_plane failed\\\' When I use the TIVidResize element I get the following error: \\\'ERROR: from element /GstPipeline:pipeline0/GstTIVidResize:tividresize0: failed to create resize handle\\\' It seems /dev/omap-resizer is missing, how do I get it? I have been using the -rc8 version with the .config posted in the Kernel compilation thread, I only increased CONFIG_OMAP2_VRAM_SIZE.

If I use exactly the same kernel command line as worked for -rc8 then I can\\\'t even boot to a gui using Ubuntu 9.10 (it boots fine until the Xserver tries to start and then it just reboots with no warning, and no useful message over the serial console). Sometimes it does have a gui for a bit before breaking. I did get it to work relatively stably with Lucid as long as I didn\\\'t use omapfb. I don\\\'t know how or where to start debugging this - do I need to change something in my config to get it to tell me more information over the serial port when it reboots? When working on 10.04, I tried to load the modules but it didn\\\'t work: I downloaded from this forum and used the defconfig. [code]armuser@arm:~/gst_demo_2.6.33$ sudo ./load-modules.sh insmod: error inserting \\\'cmemk.ko\\\': -1 Invalid module format insmod: error inserting \\\'dsplinkk.ko\\\': -1 Invalid module format mknod: missing operand after `0\\\' Try `mknod --help\\\' for more information. insmod: error inserting \\\'lpm_omap3530.ko\\\': -1 Invalid module format insmod: error inserting \\\'sdmak.ko\\\': -1 Invalid module format[/code] [code]armuser@arm:~/gst_demo_2.6.33$ uname -a Linux arm 2.6.33.1 #1 Tue Mar 23 14:18:08 CET 2010 armv7l GNU/Linux[/code] My kernel boot parameters [code]setenv bootargs-base \\\'mem=442M console=ttyS2,115200n8 vram=32M omapfb.vram=0:8M,1:16M,2:8M console=tty0 omapfb.mode=dvi:1280x720MR-16@60\\\' setenv mmc-bootargs \\\'setenv bootargs ${bootargs-base} root=/dev/mmcblk0p2 rw rootwait \\\'[/code]

    [quote=""jaustin":2b0mc3jt":22hc72kx] I\\\'ve just tried using that kernel, but it gives me _major_ stability issues. [/quote] I second that. I\\\'ve tried the same a couple of days ago, and have also gotten a lot of problems. I suspect some of them will be solved by reinstalling/reconfiguring some parts of the system since it was halfway fucked up before though ;) (I\\\'m using Ubuntu 9.10 with previous kernel 2.6.28.10-3) [code]armuser@arm:~/gst_demo_2.6.33$ sudo ./load-modules.sh insmod: error inserting \\\'cmemk.ko\\\': -1 Invalid module format insmod: error inserting \\\'dsplinkk.ko\\\': -1 Invalid module format mknod: missing operand after `0\\\' Try `mknod --help\\\' for more information. insmod: error inserting \\\'lpm_omap3530.ko\\\': -1 Invalid module format insmod: error inserting \\\'sdmak.ko\\\': -1 Invalid module format[/code] Look at your dmesg output. The kernel - when build directly from the git source mentioned above - has version 2.6.33.1. The modules expect version 2.6.33, thus insmod refuses to insert them. One possible solution (the one I\\\'ve used) is to remove the .1 from your kernel Makefile and recompile it. Best regards Ole
