There are many models in the driver kernel source code of the camera, but this can only ensure that the system recognizes the nodes. For the camera part, it is more important to debug the ISP effect file, which is highly specialized and difficult for those who have not been exposed to it to handle.

@etrin sudo mkfs.ext4 /dev/mmcblk0

@jack_admin The attached log records are all. Even if I reboot again, I only see the log with the same content. Is it possible to control the booting state from serial mode? Other boards can enter control mode using key values. What should I do with cm5?

@george I updated the OS by connecting to the top of the USB3.0 blue connector.

@george Thank you. Have a good day.
