It seems due to the less time for AWB operation. Please try to start the camera and wait a few time such as 500ms to wait the AWB Algorithm normal.
Feel free to let me know if you need more help.

Hi @lvbin
Thank you kindly! This works perfectly - Is there register for checking completion of AWB operation?
Looking to make driver robust

Hi,
There is no dedicated register to read AWB status.
