Hi,

We are using orin nx som with custom board used of L4t 36.4.

We need to port the working version 36.4 to 36.5, so in this case what are key things to take care.
expecting support from your end to resolve the issue.

It tried my self facing below issues

The error messages indicate that there are duplicate entries in /etc/fstab. This file is used by the system to mount file systems. To resolve this issue, you can try the following:

  • Check the /etc/fstab file for any duplicate entries and remove them.

  • Run the command sudo systemd-fstab-generator to regenerate the /etc/fstab file.

  • If the issue persists, try running sudo systemd-fstab-generator --force to force the regeneration of the /etc/fstab file.

2. Overlayfs idmapped layers are currently not supported

This error message indicates that the overlayfs idmapped layers are not supported in the current version of L4T. To resolve this issue, you can try the following:

  • Check if the overlayfs idmapped layers are required for your use case. If not, you can disable them by adding the following line to the /etc/fstab file: overlayfs /overlay overlay noatime,lowerdir=/lower,upperdir=/upper,workdir=/work 0 0

  • If the overlayfs idmapped layers are required, you may need to wait for a future version of L4T that supports them.
