Driver loaded, but cameras not detected

[jchillerup]

I've followed the guide on the wiki to apply the kernel patches and build the kernel for the Raspberry Pi IMX477 module. In the flashing step the authors have used the -r option to flash.sh to reuse a previously built system.img which I didn't have. So I built one using this command:

sudo ./flash.sh --no-flash -d kernel/dtb/tegra194-p3668-all-p3509-0000.dtb jetson-xavier-nx-devkit mmcblk0p1

That creates the system.img as I needed, and I verified that I was able to flash it to my NX devevelopment board. I could then proceed to flashing the DTB, and it booted. dmesg mentions imx477 so I guess I'm in the clear. (Intermission: then I apt upgraded, overwrote the kernel and had a bitch of a fight to get it booting the proper kernel and proper DTB again, but now I'm back.)

I have the problem that the Argus camera driver does not detect the camera. This is the output from gstreamer...

How would I proceed to debug this? I have removed the R8 as directed by the guide, so this should not be a power problem.

Thanks!

Here's the dmesg

I installed the ISP settings, which didn't help either :(

Following this link it seems something is coming out of the camera after all...

export SENSOR_ID=0 ?

Do you have the kernel modules properly loaded? What is the output of lsmod ?

[jchillerup]

Well, no. In fact there were no modules loaded. It seems the kernel was looking for modules in /lib/modules/4.9.140 but there was no such directory, rather /lib/modules/4.9.140-tegra. I made a symlink, and now it works! Thanks @rrcarlosrodriguez
