I would like the use the SGX graphics accelerator on the PocketBeagle to do some rendering to a frame buffer using OpenGL ES.
I have followed the steps for the BBB to get the graphics driver working, but I am hitting a dead end here:
root@beaglebone:/opt# /etc/init.d/rc.pvr start
PVR:(Error): PVRSRVBridgeCall: Failed to access device. Function ID:3223086861 (strerror returns no value.). [0, ]
PVR:(Error): OpenServices: PVRSRVBridgeCall failed. [0, ]
PVR:(Error): PVRSRVInitSrvConnect: PVRSRVConnect failed [0, ]
PVR:(Error): SrvInit: PVRSRVInitSrvConnect failed (4) [0, ]
/usr/bin/pvrsrvctl: SrvInit failed (already initialized?) (err=PVRSRV_ERROR_INIT_FAILURE)
When I do a lsmod, I can see the pvrsrvkm module is loaded, but other than that I don’t have much of an idea of what’s going on.
I’m using Debian 10 with the 4.19 kernel, which I downloaded from Robert’s website.
Any pointers would be much appreciated.
Yeah, just use the stretch iot image (with v4.14.x-ti kernel)

On first bootup, the sgx modules and libraries get setup..
Sorry, I haven't spent any time on Buster/4.19.x-ti with sgx yet..
Regards,
Ok, just gave it a try and works great.
Thanks Robert, all your work is soooo much appreciated.
Hi Robert, I’m having trouble creating an OpenGL context using egl. My programs are compiling, but I can’t get a valid context to work with. I was wondering if you had a test suite that you use to check you can talk with the SGX? Any pointers would be gratefully appreciated.
You can use glxgears to see if you are able to get a OpenGL-ES window to open.
Also, you can use glmark2-es2 to run tests on the graphics to get performance data

This works on that fruit board, so it should work with a BB.
Cheers,
Jon
