How can I create R/W type directories in OverlayFS environment configured with nv_overlayfs_config in JetPack 6.1?

Hi.

I am using Jetson Orin NX 16GB with custom carrier board.

I tried nv_overlayfs_config, which was added in Jetpack 6.x. It worked well and made it much easier to set up the overlayfs environment than the traditional method.

But on the other hand, I lost the flexibility to set any directory as R/W type.

So, how can I create any directory of R/W type in the overlayfs environment set up with nv_overlayfs_config?

Note that in my environment, I cannot use any external storage device other than the storage device on which the OS is installed.

Thank you.

Hi,
nv_overlayfs_config is not for the use-case. Please check the document:

Root File System — NVIDIA Jetson Linux Developer Guide 1 documentation

We would suggest develop your rootfs base on minimal rootfs:

Root File System — NVIDIA Jetson Linux Developer Guide 1 documentation

I understood.

I’m not familiar with the linux kernel so Iwant to modify the existing rootfs to resolve this problem. So, I decide to use custom partition and mount that as R/W finally.

I’m using this page as a reference.

But it hasn’t gone very well so far.

Anyway, thank you for your reply.
