How to mount sdcard on non GUI AGX Xavier?

[Arzak]

I’ve removed GUI on my AGX Xavier since need more space. When my Jetson has GUI, I can find my sd card mounted on /media/nvidia/xxxx after I clicked sd card icon on the left panel. After I removed the GUI I can’t find my sd card on /media/nvidia/xxxx, I think I need to run some command to mount it.
I want to run sudo mount /dev/sdXXX /media/nvidia/,but my jetson can’t seem to detect it.

There is no 32 GB sd card.

sdcard should be /dev/mmcblk1p1 if it is really on the devkit’s sdcard slot.

Related to this: The content mounted in “/media” needs to be owned by the logged in user. That’s why it mounts after you log in to the GUI. You can add rules to “/etc/fstab” naming the partition @WayneWWW mentions, “/dev/mmcblk1p1”. Before you do though, understand there are consequences if you say the partition “must” be present, e.g., if it is not there, then boot will lock and you will have difficult rescue options.

Let’s say you’ve created directory “/mmcblk1p1” via:
sudo mkdir /mmcblk1p1
(you could use any name, this just makes it easy to remember what you mounted)

Then you could add this line which will cause the partition to be mounted here on boot if it is present, but to not fail if it is missing (assumes ext4 filesystem):

/dev/mmcblk1p1   /mmcblk1p1    ext4    rw,suid,dev,exec,auto,nouser,async,nofail      0       2

Note that " rw,suid,dev,exec,auto,nouser,async" is the same as the key word “defaults”. I’ve added:
,nofail
(it would be equivalent to use “defaults,nofail”)

There are also other options, such as mounting by specific partition ID…then you could have a separate mount point for specific SD cards, and it would mount to the correct (different) location by naming different mount points via different IDs.

Also, the last “number” field is about order of repair if something went wrong. I incremented this to be later on (rootfs is what you’d want to be first to repair in case of errors).
