Camera Driver working on JP 5.1.1 but not on JP 5.1.2

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!

please see-also Topic 266812. you may avoid this by setting min_gain_val param in DT to be greater than 1 in linear scale.

@JerryChang Thank you, it`s working now!
