Hi Elvis, For Debian, the hardware can be configured thru /boot/config.txt file. Regarding CSI cameras, CSI0 is enabled with OV5647 and CSI1 is enabled with IMX219 by default. 1. If you would like to enable CSI0 with IMX219, you can add the overlay CSI-IMX219 as the following and reboot the device. overlay=CSI0-IMX219 2. If you would like to enable CSI1 with OV5647, you can add the overlay CSI1-OV5647 as the following and reboot the device. overlay=CSI1-OV5647 You could find more details from the file. For Android, it seems not easy to be achieved, has to modify from the source code.
