I’ve been developing a custom mipi camera. I’m connecting the camera to the Jetson Xavier NX. Everything is working correctly in JetPack 4.5: I have video and my video devices powered by v4l2 and a custom driver is working correctly. The gpu gets properly loaded and I’m able to see the module with lsmod.
I want to update to JetPack 4.6, but the gpu drivers does not get loaded properly (no module loaded when using lsmod). The device tree is the same as the one I use in JetPack 4.5. I made sure that the kernel is also the latest one (4.9.253-tegra).
In dmesg I get the following errors:
nvgpu: Unknown symbol l1ss_deregister_client (err 0)
nvgpu: Unknown symbol l1ss_submit_rq (err 0)
nvgpu: Unknown symbol l1ss_register_client (err 0)
