BB-XM graphics not working for OpenGL ES, SGX demos - PVRShell: Unable to initialize EGL ? No SGX?

This post sounded like a potential solution:  eglInitialize giving an 'EGL_BAD_ALLOC' error

I edited file: /usr/bin/cputype ( From 2011 Boston ESC Demo Image) and reboot. Now pvr-init start reports:

/etc/init/d/pvr-init start

Starting PVR

Usage: insmod filename [args]

FATAL: Module omaplfb not found.

FATAL: Module bufferclass_ti not found.

mknod" missing operand after 'O'

chmod: cannot acces /dev/pvrsrvkm': No such file or directory

The terminal display the following FATAL boot errors.  Any ideas? Please? 

Since no modules are getting loaded - there is an issue with the filesystem. You can get an updated image from Narcissus (narcissus.angstrom-distribution.org/).

For debug information on SGX, refer to below.

Thank you Prabindh.

I did not consider it to be an issue with the filesystem since I expected the image I used from the 2011 Boston Embedded Systems Conference to work since it was used to demo SGX apps, used in class rooms at the conference and such.  It appeared to be an issue with the /usr/bin/cputype script.  I think my CPU id is a more recent CPU.  When I ran /usr/bin/cputype it returned 0xE00 rather than OMAP35xx.   The script expected to see a CPU id of 0xC00 to be associated with an OMAP3530.  Anyway I could never figure out how to work-around it.  

A new image sounds like a very good suggestion at this point.

Thank you,

After two weeks of trying various images and builds on my new BeagleBoard-xM I have not been able to init the SGX GPU not matter what image I use .  

Is it possible my problem is an issue with more recent CPU that reports cputyp  0xE00 used in the newer BeagleBoard-xM ?

The stock microSD card image that comes with the BB-Xm does not appear to have SGX support.   This puzzles me as I would think you would want to show this capability off.  I feel like I am missing something obvious to all the the other experienced users.

Here is what I am seeing towards the end of the boot process:

I read http://processors.wiki.ti.com/index.php/SGXDbg without seeing anything that sounded similar.  

Any advice or suggestions from the wise is greatly appreciated.

BeagleBoard-xM

As mentioned earlier, you are using an outdated filesystem/ kernel. Please use the SDK from below site:

http://software-dl.ti.com/dsps/dsps_public_sw/am_bu/sdk/BeagleBoardSDK/latest/index_FDS.html

For releases for all TI platforms, check below page:

Hi Prabindh,

Thank you for your patience and pointing me to the new TI SDK for BeagleBoard 05.05.  I can see the new SDK installer  and setup script are great for newbies like me.  It automatically installs missing dependencies and sets up tftp, nfs, and minicom.  That by itself had taken me days to figure out.  

Unfortunately I am having issues mounting root filesystem via NFS. The BB-xM Rev C does not have NAND and I can not use the minicom script that setup.sh creates.  It crashes when it calls saveenv.  I resorted to using a SD card with a uEnv.txt file. 

Please, if you have a moment, please review and tell me what I might be doing wrong?

Are you able to boot and use a rootfs from SD card, as a first step ?

Thank you for your reply.

Yes!  The /bin/create-sdcard.sh script worked great!  Finally I can see SGX demos running on my BB-xm! Thank you!

I guess the problem points to either my uEnv.txt or /etc/exports configuration.  I am puzzled why it can NFS load the '/home/z3/ti-sdk-beagleboard-05.05.01.00/targetNFS/boot/uImage' but not the filesystem at '/home/z3/ti-sdk-beagleboard-05.05.01.00/targetNFS' ?

Thanks again,

-Ed
