I am trying to get a BBXM running with the SGX libraries. The requirements of my project are to run an EGL2 application without an X11 server. I’ve followed the steps on http://elinux.org/BeagleBoardUbuntu without success.
Using Ubuntu 13.10 built kernel version 3.13.5-armv7-x11 but I get no video on my Samsung SyncMaster 931c. Only the orange screen from u-boot then no signal.
I’ve tried installing the “Graphics SDK release 5.01.00.01” from TI’s website. Installation appears to go smoothly but the pvr service fails to load. Do we know what version of Linux the SGX libraries will work with?
Does anyone have an idea of what direction I need to go in to achieve this?
I had some success with the 3.7.x kernel and the SGX libraries! However I could not get the kernel to boot fully with Ubuntu 13.10 (ubuntu-13.10-console-armhf-2014-02-16.tar.xz). I ended up using an old Ubuntu 11.10 I found on our file server (ubuntu-11.10-r14-minimal-armel-2012-09-27.tar.xz).
I might be able to continue using 11.10 but if at all possible we would like update. Can you suggest a version that is more likely to work?
I was able to get Ubuntu 13.10 to boot with this kernel.
By changing my uEnv.txt to http://pastebin.com/NWuYSYd8 there appear to be no issues. I’ve not tried to install the SGX libraries but I suspect they will work, that will be my next task if I decide to abandon the 11.10 version.
I have similar issues and achievements. More precisely, I have Beagleboard-XM + 3.7.x stable kernel + Ubuntu 13.10 + Graphics_SDK_setuplinux_4_08_00_02. Both kernel and SGX have been built through the stable-kernel scripts. I do see a
Graphics_SDK_setuplinux_4_08_00_02_hardfp_BinOnly.bin so I guess that it can work. The log below my signature is pretty encouraging.
Nevertheless, I cannot run any demo. I receive the following error:
bash: /opt/sgx/GFX_Linux_SDK/OGLES/SDKPackage/Binaries/X11/Demos/EvilSkull/OGLESEvilSkull: No such file or directory
bash: /opt/sgx/GFX_Linux_SDK/OGLES/SDKPackage/Binaries/Raw/Demos/EvilSkull/OGLESEvilSkull: No such file or directory
The files obviously exist.
Any idea what I’m doing wrong?

------------------ SGX 3D Blit test -----------------
------------------------ End ------------------------
I had not tried the demos besides the ones that reside in the same directory as the blit test. I decided to give EvilSkull a shot on my board. I noticed however that the instructions on http://elinux.org/index.php?title=BeagleBoardUbuntu&oldid=314498#SGX_Video_Acceleration are not 100% correct. Specifically the step after running the blit test. Wiki says:
tar xf GFX_Linux_SDK.tar.gz
cd GFX_Linux_SDK
tar xf OGLES.tar.gz
I had to do:
tar xf GFX_Linux_4.08.00.02_examples.tar.gz
cd GFX_Linux_SDK
tar xf OGLES.tar.gz
From there I was able to run:
/opt/sgx/GFX_Linux_SDK/OGLES/SDKPackage/Binaries/Raw/Demos/EvilSkull/OGLESEvilSkull
Keep in mind that I ran the RAW version. I have no idea what that will do under X11. I don’t have xorg installed so I cannot validate that the X11 version of EvilSkull actually works. I am running Ubuntu 11.10. Might be nothing but my uname is different. Maybe we have different kernels. I changed nothing when building the kernel.
