Hello,
First off I am using the 3.2 kernel from SDK 6.00.00.00 as well as the toolchain from this version and this is a custom board.
Everything is working pretty smoothly so far and i can see the Penguin on the display when i boot so i know the display stuff is working. Where I am having issues is with the Graphics SDK stuff. I am using the Graphics SDK version 4.10.00.01 and i installed only version es8.x and the SDK. I then built it with the following:
1. Modify Rules.mk to point correctly to the SDK Path, the linux toolchain directory, and the linux kernel directory.
2. Make the SDK: make BUILD=release OMAPES=8.x all
3. Install it: make BUILD=release OMAPES=8.x install
The install was set to the root file system for my target and there were no errors on the build. Then on the target i started it up and ran /etc/init.d/335x-demo. Everything installs fine but once pvrsrvctl is called it crashes out.
So basically it fails when running rc.pvr. I broke this script out and ran it in pieces to find the issue:
modprobe pvrsrvkm -> runs fine and loads the module; however, the module is tainted(G)
rm, mknod, chmod -> all run fine to remove and recreate the pvrsrvkm device
pvrsrvctl --start --no-module -> This is where it bombs out on me.
Any idea what the problem could be? I have found other issues searching online but most occur after everything is loaded and running. I am bombing out before i can even load in omaplfb. I will probably try some of the other things i see even though the issues are different, but figured I'd post here first to see if anyone has any ideas.
Here is the output from gfx_script.sh AFTER loading pvrsrvkm but BEFORE running pvrsrvctl:

I haven't made any big changes to the kernel, I obviously had to change my config file to properly init my custom hardware but didn't change the display stuff and the sgx_init function is still called. Any suggestions or advice would be greatly appreciated!
Thanks,
Jarrod
