Other Parts Discussed in Thread: TPS65987
I'm having problems with my setup, that the bridge says dsi underrun while de Screen remains dark, but the whole linux side doesn't know about that. Restarting the graphic chain by executing chvt 1/7 allowd me to get it running again. My setup is as follows:
iMX8MM with MIPI-DSI -> sn65dsi86 -> tps65987 -> USB-C -> Panel
The iMX8MM is running Linux, where the DTS is describes the chain from iMX to Panel exclusing the TPS. I tried to handle the bridge interrupt but failed so far. Even if I manage to handle the error interrupt from within the bridge driver, i still don't know what to do to re-enable the chain. Anyone experiencing something similar or havong an idea, where i could start looking for the root cause?
