I’m using jetson orin nano super, dev version is R36.4.3. I modified the tegra_camera source code. After build it on my pc, i copy the tegra_camera.ko to the orin board /lib/modules dir.
But It seems load failed. Blew is the error info:

The compile method is from : https://docs.nvidia.com/jetson/archives/r36.4.3/DeveloperGuide/SD/Kernel/KernelCustomization.html

How can i make it work?

Thanks!

Should the file path should be "
/lib/modules/5.15.148-tegra/updates/drivers/media/platform/tegra/camera/tegra-camera.ko" ?

i already copy file to /lib/modules/5.15.148-tegra/updates/drivers/media/platform/tegra/camera/tegra-camera.ko".
/home/wheeltec/serdes/code/tegra-camera.ko just the same file.

We don’t see the problem by follow the document to build the .ko

How do you get the source code. Could you try download from the DLC to try again.

Thanks
