We are currently having issues trying to connect one FRAMOS FSM:GO IMX662 Camera Sensor to the second CSI2 channel on our custom carrier board with the Verdin IMX8M P SoM.
Connecting it to CSI2 channel one/zero is working but we can not get it to work on the other CSI channel. It seems that the i2c connection is working and we can set configurations but after docker run…gst example and gst launch.. but the stream crashes after that. We have adapted the device tree overlay; it would be great if you could check if there is anything wrong with it:
