I am referring these docs to make startup script but since my *launch.sh file is on SD card.
so the mavros.service starts before the mounting service. to counter this I added
but still, the same problem is happening.
please refer to
/etc/systemd/system/ for default initial services.
could you please modify your script to make it runs after
okay, ill add nvpmodel.service in After = media-agx-navigation.mount nvpmodel.service
Still the problem is persisting
could you please share the content for reference, thanks
the contents of mavros.service are
could you please confirm this is actually executed?
could you please briefly describe the use-case, what’s the scenario for running this script.
are you able to run the script file,
Hi, yes I can run the script file manually. and if I manually start the service, it works in that case as well. the use case is to start the mavros service
systemctl status media-agx-navigation.mount shows me that it is working
will this works? please have a try, thanks
I tried, same problem is persisting
since you can run the script file manually, please try google it around for related system level configurations.
Hi, the problem is, the service is called before SD card is mounted, since other SBC’s are booted from SD card self (Raspberry Pi) less info is available for this problem
help is appreciated
I’ve not worked on this, but here is a command you’ll be interested in looking at:
systemctl list-units | egrep -i 'mount'
On a TX2 (might differ from AGX, but likely is the same) I see:
# systemctl list-units | egrep -i mount
proc-sys-fs-binfmt_misc.automount loaded active running Arbitrary Executable File Formats File System Automount Point

The ones you will be interested in for an SD card might be run one of two ways:
- As an individual user (the service mounts under “
/run/user/<user ID>”), or
- As the system (no “
/run” file, part of
Note that mounting as an individual user occurs later than regular mount, and is typical of an SD card which is not the root filesystem. Probably this is what happens in your case.
If this runs as an individual user, then the mount point is the user’s ID number (
UID) as the subdirectory of “
/run/user”. So if a mount shows up under “
/run/user/0”, then this is a late mount by user
root; if this is showing up as a numeric ID other than
0, then this is running as that user. On the system I am looking at the Gnome Display manager has UID 120:
# grep 120 /etc/passwd
gdm:x:120:124:Gnome Display Manager:/var/lib/gdm3:/bin/false
(and thus exists “
Did you add an
fstab entry (in “
/etc”) for the partition to mount? Or is this being auto-mounted as a user?
It is being auto mounted under /media/agx/myfolder
Thus this is an automount based on the user logging in to the desktop. This needs to instead be mounted via “
fstab” so that it can mount earlier. One problem is that sometimes automount needs to be disabled if you are mounting via
fstab (sometimes automount will incorrectly mount the SD card twice). When the SD is mounted automatically, what do you see from:
df -H -T /media/agx/myfolder
Also, what do you see from:
From the above we can find out the best way to add an entry to
