On AM69 Starter Kit, this is routed to I2C-1, so enable the instance, TCA9543 I2C switch and the TCA6408 GPIO expander on the bus. AM69 SK has the CSI2RX routed to a MIPI CSI connector and to 22-pin RPi camera connector through an analog mux with GPIO control, model that so that an overlay can control the mux state according to connected cameras.
