Tool/software:
I have a custom system-on-module based on the BeagleBone Black. We are running the Processor SDK 9.01 built with the Yocto Project. Our u-boot and kernel versions are the versions shipped with the Processor SDK Linux 9.01.00.001 release.
I have been attempting to get the graphics demos running on our system, but I am having some trouble getting the graphics coprocessor drivers to load.
Some Yocto-related background:
- I have gpu in my machine features (machine .conf)
- opencv, x11 have been removed from the distro features (distro .conf)
- I have libegl, libgbm, ti-sgx-ddk-km, and ti-sgx-ddk-um added to IMAGE_INSTALL
- I have tried two packagegroups in an attempt to get something running:
- packagegroup-arago-tisdk-matrix
- packagegroup-arago-tisdk-graphics
- My image inherits "arago-image-inc"
- My machine inherits ti33x.inc
Attached to this post is a text file containing:
- PVR-related Kernel Messages
- The outputs of the "gfx_check.sh" script
I would like to know:
- What packages need to be included to
- Run the graphics coprocessor
- Load the graphics demos
- Run an opengl/SDL2 application utilizing the SGX Coprocessor
- What changes need to be made to get the SGX drivers to load successfully
Thank you,
Jeff
