The dmesg log of jetpack6 is the same as jetson5, but the dev directory no longer has a video device.
hello bobliu1,
please share the kernel init messages, is there error reported when device registration?
besides, please refer to Port Binding section to examine port binding results.
I will provide the log file later. There is an obvious problem at present: after initialization, there is no video device under the /dev/ directory, and there is no error log.
hello bobliu1,
the issue should be on sensor side, 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, (/dev/video0).
please see-also Topic 293662 and Topic 290610 to examine camera device registration process.
