Drivers for L4T 32.7.2 - Xavier NX

Nvidia Jetson Nano/NX Cameras
1

Hi,

I tried to install the Arducam drivers for the NX Kernel version 32.7.2 using the install_full.sh script. It seems that there is no corresponding release yet.

Kernel version: 4.9.253-tegra-32.7.2-2022041724839
Jetson type: Xavier NX (Developer Kit Version)

Will the drivers for this kernel version be released in a near future ?

Thanks for your help.

hi, @andre

The L4T32.7.2 Jetson nx driver has been adapted. We will release today.

Hi,

Thanks for the release. I see you’ve made it available for the kernel version: 4.9.253-tegra-32.7.2-20220525063328
My kernel version is actually: 4.9.253-tegra-32.7.2-2022041724839

I still tried using the release you made available but after reboot I still have the tegracam sensor driver imx219_v2.0.6 installed instead of the arducam one.

Should I wait for a release for my kernel version or may the problem be due to something else ?

Thanks for your help.

hi, @andre

4.9.253-tegra-32.7.2-20220525063328 The timestamp here is the time when the deb package was packaged, not the kernel time. If you can install successfully, it means that the kernel version is correct.

You can execute the following command to see and provide me with the execution result:

dmesg | head

cat /boot/extlinux/extlinux.conf

ls /boot/arducam/dts/tegra194-p3668-0000-p3509-0000-user-custom.dtb

Hi @yang,

Thanks for your answer. Here are the results of the commands:

# When testing a custom kernel, it is recommended that you create a backup of

# fallback to the original kernel. To do this:
#
# 1, Make a backup of the original kernel

# 2, Copy your custom kernel into /boot/Image

# 3, Uncomment below menu setting lines for the original kernel

I understand what the problem is. This is a bug in L4T32.7.2.

You can refer to the link below to fix it:

Thanks for the link.
I’m still not sure of what the problem actually is. I’m booting from an external NVMe. Should I change the root path in the extlinux.conf file ? Or is it the cboot that should be rebuilt and reflashed ? Sorry the nvidia thread is quite confusing. I understand this is no longer an issue from your side.

If using SDKManager software.

You need to recompile cboot and use it to replace the original cboot. Re-burn into the system.

Below is the download link of the cboot source code.

Thanks for your help. I’ll look into that then.
