hello jack31,
may I know which JetPack release you’re working with?
please refer to the position property description in Sensor Software Driver Programming, you cannot remix the camera position values with a two-camera plus a six-camera system.
if you’re using r32.6.1,
please refer to Multi-camera Jetson Xavier NX configuration, more than 6 cameras - #10 by JerryChang and apply the patch to fix “Invalid sensor placement is set” failure, and also the reference for the property values to configure more than six camera system.
thanks
