hello shaorui,
I don’t think this is default supported camera driver.
please review your device tree settings, you should also modify the kernel layer for your use-case.
thanks
hello JerryChang,
I has not development board,please Please try rmmod cmaera driver,Thanks
hello shaorui,
what’s the platform you’re using, is it a customize board instead of Xavier NX DevKit?
the default supported camera drivers for Xavier NX are… imx219, and imx477. however, it’s another story if you’re using a customize board.
Dear JerryChang,
I using a customize board,but the camera do work,only donot rmmod camera driver, why the problem is ?
hello shaorui,
this command, rmmod
remove the kernel module, did you compile the driver as module, such as *.ko
?
Dear JerryChang,
I compile the driver as module,(nvp6188.ko).
hello shaorui,
you should review the driver implementation, did you shutdown the camera device completely before remove the kernel module? what’s the kernel messages reported while running rmmod
?
please also check developer guide for reference, Loadable Kernel Module (LKM).
thanks
Dear JerryChang,
I check developer guide for reference,Thanks
