DTB or kernel issue with Jetpack 6.1 on Jetson Orin NX, ReComputer J40?

[J-Anderrueti]

I was able to flash the ReComputer J40 with Jetpack 6.1 according to the seeed studio instructions, but I don't manage to get 2 Arducams with IMX477 working on it. Somewhere I read that there might be an issue with the dtb file? Something that "...p3767-0005..." would be needed but only others are available? At the moment, after flashing, its kernel_tegra234-j401-p3768-0000+p3767-0001-recomputer.dtb
Can you help me?
Have a nice day!
