Jetson nano has four external cameras and uses TCA9546A for I2C expansion. How to modify the four cameras to work normally at the same time, is there any relevant reference materials?
Nano devkit should only support 2 sensors. Did you implement your own carrier board?
Yes, the carrier board designed by myself
The official software supports 4 cameras? Do I need to modify the device tree?
Have a reference to below document to implement the camera drivers.
