Hi all, I am installing csi2 driver for my Jetson TX2 (Jetpack 4.6.1, l4t-32.7.1) with release 4.0.0~beta1, and I am facing an error when copy, extract tarball to target device and run command: sudo ./install.sh:

Please help me out, thanks in advance.

Faceing exactly the same issue on new setted device (jetson nx)

[nikitamankovskii]

Some more information: The error mentioned before can be fixed with:

sudo apt update
sudo apt upgrade

BUT here next problem appears - wrong dependances version:

The following packages have unmet dependencies:
 avt-nvidia-l4t-bootloader : Depends: nvidia-l4t-tools (= 32.7.1-20220219090344) but 32.7.2-20220417024839 is to be installed

Looks like its regardiung the update the Jetpack Version: 4.6.2, which you are getting with installation on 4.6.1

Have you solved your problem? If not yet, you can follow installation instruction in (https://github.com/alliedvision/linux_nvidia_jetson/tree/l4t-32.7.1/avt_build/jetson_build/installer)/install.sh. In my case, I just install nvidia-l4t-tools with specified version (= 32.7.1-20220219090344) and install manually ONE BY ONE these packages: avt-nvidia-l4t-bootloader avt-nvidia-l4t-kernel avt-nvidia-l4t-kernel-dtbs avt-nvidia-l4t-kernel-headers (these packages can be found in line 70 of install.sh file. And it works after I reboot my jetson. Hope this may help you.

I installed jetpack version 4.6.1, I have no idea why my jetson have both jetpack version 4.6.1 and 4.6.2

I'm having the same issue. After a fresh flash of JetPack 4.6.1 using the NVidia SDK Manager, I get:

The following packages have unmet dependencies:
 avt-nvidia-l4t-kernel : Conflicts: nvidia-l4t-kernel but 4.9.253-tegra-32.7.1-20220219090432 is to be installed  

After upgrading with sudo apt update and sudo apt upgrade, it seems like apt sources the newest debian packages for JetPack 4.6, which upgrades the packages from L4T 32.7.1 to L4T 32.7.2, which causes the same bootloader mismatch that @nikitamankovskii had.

In my case, I just install nvidia-l4t-tools with specified version (= 32.7.1-20220219090344) and install manually ONE BY ONE these packages: avt-nvidia-l4t-bootloader avt-nvidia-l4t-kernel avt-nvidia-l4t-kernel-dtbs avt-nvidia-l4t-kernel-headers (these packages can be found in line 70 of install.sh file.

@tanvubc I'm encouraged to hear you found a solution, and I'm eager to understand more about how you did it. Could you explain the steps you took to do these specific installations? How did you set the specific version of nvidia-l4t-tools?

Hi @aidanwhelan, after re-install this driver once again, I realized that the only problem is my jetson has mismatch version of nvidia-l4t-tools. So you can try manually install nvidia-l4t-tools with right version and run command sudo ./install.sh again.

I ran command sudo apt-get install nvidia-l4t-tools=32.7.1-20220219090344
