Hi expert,

customer use OV9284 + FH8310 +933 in their project, the FH8310 is ISP.

we have below problem:

1. they build 20 pcs board, found the frame rate is not stable. Normally it is 30fps, but some board only 26fps.

2. they use FH8310 to upgrade 933 sofeware by I2C, it found some boards are failed to upgrade.

I attached the customer schematic, could you help check and give some suggestions? thanks in advance.
