Programmers from our team have reported similar observations.

I have not yet had a chance to help them investigate.

This is a real shot from the hip, but here goes anyway.

Default code does not turn on interrupt handling for serial communications to/from the camera.

What about an interrupt processing issue?
Does the UART have a funny state on power up (only some of the time)?
Does the power up of the camera enter into the problem?
Camera first then RC. RC first then Camera. Does this change the situation?

How does data get from the master microprocessor to the user microprocessor? DMA, Dual ported ram, serial ????

How can the camera code affect this?
