Firstly, I know that there are several very similar topics in the forum, and it’s very possible that this topic is redundant, if so - apologies.
That being said, it seemed to me that none of the existing MicroSD topics exactly suited my situation, and I didn’t find a solution which solved my problem.
I am using the AAEON-8250AI Jetson Xavier Nx , which came flashed from the provider.

jtop application says Jetpack version is:
4.4.1 [L4T 32.4.4]
As of last Tursday, I was using a 64GB Micro SD card in the Jetson, which was being auto-mounted via
This is the
fstab entry that was successfully mounting the SD card:
UUID=2ef05944-2e9d-4053-bd7f-4bde7c326886 /mnt/NxSD64GB/ ext4 errors=remount-ro,auto,rw,user,exec 0 0
Last Thursday I rebooted the device, and all of a sudden the MicroSD device disappeared (and, obviously, the auto-mount fails - I had to remove the line from
df -h - none of these commands show the MicroSD device.
Following a suggestion in another topic I ran the command:
dtc -I fs -O dts -o /tmp/extracted.dts /proc/device-tree
Here is the output:
extracted.dts (246.5 KB)
Indeed sdmmc3 has
status = "disabled", but I’m unclear how I can change that.
There is no
flash.sh script on my Jetson.
There doesn’t seem to be any
Linux_for_Tegra directory anywhere on my Jetson.
There is an additional problem, which has started at the same time, but I don’t know if it’s related.
Since the same reboot which disappeared the MicroSD device, I am unable to start a GUI session (see image below). I am only able to connect via a virtual console (i.e:
ctrl + alt + f2)
