hello Mr.Elephant,
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.
It seems like probe driver successfully and no error returns. Or is there any other details that I need to notice?
I’ve already browsed these two topics before, and couldn’t solve it and come to here to issue.
hello Mr.Elephant,
just double confirm, was this driver worked with r35.4.1 release version?
It works well on r35.1, r35.2.1 ,r35.3.1 and r35.4.1.
Now i want to port to jp6.0.
please also check Camera Driver Porting since you’re moving to kernel-5.15
