Part Number:AM5718
Tool/software: Linux
Hi,
I tested the dual LCD output on the am5718 platform. I have tested DPI-0 and DPI-1. It is normal to use DPI-0 or DPI-1 alone, but only DPI-1 works when both are used at the same time.
Weston will report a timeout when it starts
[ 702.540911] omapdrm omapdrm.0: atomic complete timeout (pipe 0)!
Weston stops causing the Linux kernel to crash
