Linux/AM5728: Weston startup log, failed to choose EGL config for output

Part Number:AM5728

Tool/software: Linux

Hi,

a customer is trying to bring up Weston on their custom HW. with AM5728. We tested the modetest colorbar test and that works.

Currently the difference between the AM5728 IDK with Processor SDK weston.log and the customer weston.log is the following:

Is there a dependency missing or kernel driver not loading properly?

Thanks,
