Other Parts Discussed in Thread: AM3358, AM3354, AM3359
Tool/software: Linux
Hello,
Does anyone know of a software work-around on Linux for the lack of an SGX graphic accelerator on the am335x processors that are missing it, specifically the am3352?
My current situation is that I'm trying to build a boo2qt image with the Yocto project for a custom board, where the designers chose to use the am3352 instead of the am3354, am3358, or am3359. I built my image using ti-sgx-ddk-um for virtual/egl, virtual/libgles1, and virtual/libgles2 knowing that it probably wasn't going to work and got the drm and pvr errors below:
[ 14.015412] [drm] Initialized

[ 17.338093] PVR_K:(Error): SysInitialise: Failed to Enable system clocks (175)
To state my previous question with more of a context to my situation, what are the alternatives to ti-sgx-ddk-um that would be used for virtual/egl, virtual/libgles1, and virtual/libgles2? Mesa?
A few weeks ago I was able to get core-image-sato working on my board with the linux-yocto-4.9 kernel and no sgx, so I know this is possible. I'm really looking for suggestions that others have found to work best for the am3352.
For anyone who is curious, here' my build configuration (bei7 is my board and it's associated meta layer):
