I tried to test this patch with sensor_test demo. But it return this error:

** I changed config /mnt/data/sensor_cfg.ini to yours and apply another changes from pull request and recompile image.

i also tried with the same result, may be we use wrong connector?

Maybe, I use RPi Zero Camera (blue textolite) with default ribbon. But I don't check pinout of csi port on board and on camera module. But anyway there are some problems with software.
Lane_id: 0, 1, 2, 3, -1 is incorrect for new RV boards revision, but even I changed them it doesn't affect. Also, I think it is not good idea to use system("devmem <...>") for camera init.

The RPI camera ov5647 has pull-down (to GND) resistors R4,R8 on I2C pins.
After removing this resistors my licheerv-nano can recognize this camera, but now I have another problem:
