I applied the OV10640 quad camera after changing the graph according to the demo of the OV10635 four cameras.
After the compilation is executed, I2C0 reads 0x30 failed message.

Press Ctrl+C to terminate the demo.

Then I found cam_ioctl.c

I2C reads 0x30 error, is it related to this configuration?
If so, where should I find a reference for this configuration?
