reComputer J4012: overlayfs

I try nv_overlayfs_config to enable a overlayfs.
But, My jetson doesn’t work.
Stop booting process before start ubuntu OS.

This is how to enable overlayfs.
https://docs.nvidia.com/jetson/archives/r36.2/DeveloperGuide/SD/RootFileSystem.html

sudo nv_overlayfs_config -e
reboot

I flashed JP6.0 as described below.

Please let me know how to fix this.
Thank you
