Mkdir doesn't work

Hi. I’m having trouble creating a directory as root on one of the Xavier cores. I’m connected to it via ssh.

# echo $USER
# pwd
# mkdir test
mkdir: test: No such file or directory

What steps can I take to see what is wrong here?

Dear @DjordjeTTTech,
By default, root partition is read-only. Please see if it helps

I cannot access this link. ( Sorry, this page may have moved, doesn’t exist or is private.)

Also, how can I check/verify/modify these partitions and their permissions?
df and mount give me this:

# df
/dev/vblk_mnand0         8388576   5050008   3338568      61%  /               
/dev/vmtd_qspi0                0         0         0     100%  (~C)

/dev/vblk_mnand1        16777216  16777216         0     100%                  
# mount
/dev/vblk_mnand0 on / type qnx6 

I don’ t see any partition named root.

Also, I don’t have problems making a dir in the / directory.

# mkdir /test

I have already performed this modification prior to flashing:

Change drive-t186ref-foundation/virtualization/pct/e3550b03-t194 a /qnx/boot_chain_storage_qspi.cfg file to +virtual_storage_ivc_ch=0x8<GID_VSC_SERVER>800623 from -virtual_storage_ivc_ch=0x8<GID_VSC_SERVER>810623

also I removed read-only statements from:

Dear @DjordjeTTTech,
Please mount the partition and use like below. Does that serve purpose?

mkqnx6fs /dev/vblk_mnand1
mount /dev/vblk_mnand1 /mnt
# mkqnx6fs /dev/vblk_mnand1 
All files on /dev/vblk_mnand1 will be lost!
Confirm filesystem re-format (y) or (n): y
Format fs-qnx6: 2097148 blocks, 65536 inodes, 8 groups
# mount /dev/vblk_mnand1 /mnt
mount: Can't mount /mnt (type qnx6) 
mount: Possible reason: Permission denied
