Hello everyone.
I am attempting to install the Graphics SDK drivers onto my SDK 6.00 target board, which is an am335x starter kit.
I followed the guide over at http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide , but after deploying the modified rootfx and kernal uImage I get the following stack trace:

Any suggestions? I noticed this snippet:
SGX driver information
cat: can't open '/proc/pvr/version': No such file or directory
Not sure why it wouldn't be able to find that.
Thanks.
