hello b3204sunil,
are you working with rel-35 or rel-36?
for instance, may I double confirm which Jetpack release version you’re working with?
please examine release tag, such as $ cat /etc/nv_tegra_release for confirmation.
you may refer to Jetson Compatibility,
please aware that Orin Nano module is not pin-compatible with Xavier NX carrier board.
anyways,
during kernel initialization stage, it’s step for camera device registration to setup a video device node to linux kernel. sensor probing only run once during kernel initialization stage of system boot-up.
for a typical camera application running cycle, the driver will Power On the sensor, Start Sensor Streaming, sending relevant v4l2 controls, and finally power off the sensor.
so… if there’s a error returns, it’ll not register a video node, (i.e. /dev/video0).
please see-also Topic 293662 and Topic 290610 to examine camera device registration process.
