IntroducingPVRUtilsGLES on Beagleboard X15

Hi,

I’m having issues with running the SDK example IntroducingPVRUtilsGLES on my Beagleboard X15 that I’m not quite sure how to debug.

My setup:
Processor: AM572x General Purpose EVM (aka Beagleboard X15), with SGX544
OS: TI’s AM57xx EVM Linux image (6.03.00.106)
PowerVR SDK Version: 5.6@3f88b0f
Window System: Wayland

I have been able to compile and execute HelloAPI and IntroducingPVRShell examples successfully. All of the framework libraries necessary (PVRAssets, PVRCore, PVRSHell, and PVRUtilsGLES) have been built and deployed.

Here’s my console output, with the errors I’m encountering in bold. The application errors in a segmentation fault.

I have also built the SDK for Windows, and am not getting these errors.

Are there any recommendations as to how to debug this issue? I believe these errors happen after the call to MakeCurrent in EglPlatformContext.cpp (line 1107) but that’s as much visibility as I have.

Please let me know if more information is required.

Thank you,
Josh

Hi, Please disregard this post. I had forgotten to compile PVRAssets with the Wayland preprocessor definition, so EGL was returning an EGL_BAD_MATCH error. I quickly debugged it and now I’m passed this error. I will leave it here in case anyone else encounters this issue.

Happy New Year!
Josh
