DS90UB936-Q1: Recover from unstable connection unable to communicate by i2c

Part Number: DS90UB936-Q1

Dear Sir,

    I suffered an issue on my project which was using DS90UB936 & 935 to receive video frame from camera module.

Currently, it could receive video frame from camera module via DS90UB935 and 936 properly.

The OK case's UB936 register dump as below, and it should be appearing 7 devices on the same i2c channel.

But if the connection unstable then it could broken the video transmitter and unlock temporary then lock again, but from ub936's register dump it seems be reset to default value.

I tried to re-initial ub936 again, but it still unable to communicate with related device where on camera module (as like ub935...etc), so the i2c bus still exist ub936 only.


Is it possible from the 936 register dump to provide me advice what may be possible reason cause fail to communicate with other 935 side device via i2c in this situation?

Thank you,

--Blake
