Hi, I'm currently facing a challenge with the VD55G1 driver. I've designed my own minimal system board for the N6 and VD55G1, using MIPI CSI for communication. When attempting to drive the VD55G1, I can enter the stream mode but no data is being transmitted (the N6 interrupt is not triggered). Upon reading the stream_fsm register of the VD55G1, I noticed it remains stuck in the dark task, with the REPEAT_COUNT, CURRENT_CONTEXT, and NEXT_CONTEXT values consistently showing 0 0 1.
Here is my code
testfsm means getting the value of the stream_fsm register.
I would greatly appreciate your prompt assistance in resolving this issue. Thank you.
