Yes, This issue occurred on the Arducam 22-pin IMX577 module.
I have tried changing the sequence of regulator, reset, and clock, and 
found that this module must wait a sufficient amount of time after reset 
before registers can be written (10 ms is a safe duration). This issue 
did not occur when using other IMX577 modules.
