Hello Yocto Community,
I am trying to get an IMX8 board from TechNexion to boot using the netboot command from within uboot. (IE mounting the filesystem remotely)
I have configured tftp and the NFS server and initially things seem to be working: the board boots, starts the kernel that was grabbed using tftp, and then starts using the remote filesystem.
Then the following kernel error messages are produced:
...
.....
[ OK ] Started udev Wait for Complete Device Initialization.

systemctl status sys-kernel-debug.mount gives:

The mount error seems prevalent across all the errors. somehow UID is 1000 when it should be 0 during boot?
On the Host side, here are the /etc/exports options for NFS:
*(rw,sync,insecure,no_subtree_check,no_root_squash)
Any help would be greatly appreciated,
