Hi,
we are using a Jetson Orin NX, sitting on a Seeed Studio J401 Carrier-Board. We got our Camera working on l4t 5.1.1, but on l4t 5.1.2 the same driver and dtb won’t work. We get the following error:
timo@testsetup:~$ sudo dmesg | grep imx

Is this caused by the failed module verification?
Is the driver signing enabled by default in the default kernel Image?
Any help would be greatly appreciated!
