Nv-l4t-bootloader-config systemd service fails

I just installed and updated the latest Jetson Nano release and if I run systemctl --failed I see that the nv-l4t-bootloader-config.servie is failing.

I tried to dig into the script and I managed to find that is caused by

dpkg-reconfigure nvidia-l4t-bootloader

Anyone an idea what is going wrong here?

Hi goertz,

Could you share the detailed step you’ve done to hit this error? also tell us the purpose of these steps if possible.



Ok, I’ll give a summary of what I have done.

I don’t need the graphical stuff so I just boot to text mode

systemctl set-default multi-user.target

Just to be sure that I’m on high power mode

nvpmodel -m 0

Disable swap for kubernetes setup (read that this is sometimes neccessary)

swapoff -a

I set nvidia as my default docker runtime to have GPU enabled kubernetes

vim /etc/docker/daemon.json

“default-runtime”: “nvidia”,

Update the system to the latest and greates

apt update && apt upgrade -y && apt dist-upgrade -y && apt autoclean -y && apt autoremove -y

Add myself to the docker group

sudo usermod -aG docker $USER
sudo newgrp docker

That was all after the reboot I did my obligatory

systemctl --failed

and found the issue above.

For Debugging I also set the default target back to graphical. This lead to exact the same result.

Sorry for late reply. I think setting docker here is the cause of your issue.

Could you check?

Hi, I’m not sure what you mean by setting docker. Do you mean adding myself to the docker group oder setting nvidia as default runtime for docker?


Sorry that I am not very familiar with docker.
What I wanted to point out is I guess you are trying to run docker on jetson nano but you hit the error, right?

Then my problem is it necessary to run nvidia-l4t-bootloader deb file in your usecase? This service is used for OTA update for jetson nano bootloader.

I’m not sure if it is necessary to have the nv-l4t-bootloader-config.service not failing. Everything seems to work fine even with this service failing, but on my systems I normally don’t like failing services, so I wanted to report it to be investigated.

I am wondering such tool may conflict with docker environment. Such tool needs to access the partition on system directly. If this is not needed in your case, I would say you could disable this service by systemctl first.

I did not really configure anything docker related, ist mostly what comes out of the box from the latest image. But I will disable the service for now (which I already have).

Oh, do you mean you didn’t enable any docker container yet but just run the steps from above comments?

Actually, I think the one that might cause problem is either the docker or the

apt update && apt upgrade -y && apt dist-upgrade -y && apt autoclean -y && apt autoremove -y

If this does not cause by docker, then probably the apt commands are the cause. I don’t think disable graphical mode or nvpmodel would be the cause.

I will check it with my device. Thanks for report.

And one more thing to check… which release do you see this error?

I installed the JetPack 4.3 SD card image from the download page.

Oh, do you mean you didn’t enable any docker container yet but just run the steps from above comments?

Yes, the commands above where all that was necessary on a vanilla cloned sd card. No other command ran before.

Hi goertz,

We can’t reproduce this issue by following your comment #3 steps on r32.3.1/Nano B01.
Is this still an issue at your side? Any result can be shared?

Hi @kayccc,

I’ve just seen I have the same problem on AGX Xavier after a problematic OTA upgrade where it ran out of disk space. This might give a way for reproducing this.

I had not really noticed till now, but this might be related to several problems i have been facing with Argus since then.
I get:

sudo systemctl --failed
  UNIT                             LOAD   ACTIVE SUB    DESCRIPTION                      
● nv-l4t-bootloader-config.service loaded failed failed Configure QSPI bootloader service
● systemd-modules-load.service     loaded failed failed Load Kernel Modules              

Seems reasonable to me to first try fixing the former one.

I have tried @WayneWWW’s command without improvement.

How can I debug this ?
Is it possible to fix it without flashing ?
Or download only the required partition/image for flashing (preferably from Xavier itself) ? Sadly, I have low internet BW so far and a new SDK manager and SW takes almost one day to download…Flashing previous version and OTA upgrade is almost the same :-(

Hi Honey_Patouceul,

Actually we didn’t provide any solution yet. The command you pasted is just a step from another user and I was trying to figure out why he could reproduce this issue.

So do you mean this issue could happen if the disk space is running out? Also, what is the exact error you will hit when running the OTA? It must have some error that makes you to check the systemctl, right?

Hi @WayneWWW,

Yes, it happened when I upgraded OTA from R32.3.1 to R32.4.2 with about 3.5 GB of free space in eMMC.
The upgrade first downloaded about 2.5G of packages and then started the upgrade without any warning about space requirement.

After it had installed a few packages, I have been warned by Ubuntu that the system was running out of space. I thought I could reboot in order to clean cache from already installed packages. When I tried to reboot, I got a popup window about nv-l4t-bootloader install asking me to confirm. I did.
Upon reboot, my rootfs was full, and I’ve had to use serial console for deleting folders and make some room for install to terminate. I had noticed that the apt cache was full of both and new verions of packages. I did fix that with the commands from the above mentioned post and I was thinking it was cleared.
Only one month later I’ve seen that this system unit was failing. It is globally working, only had some problems with Argus, not sure if it is related or if it was because I had low disk space.

[EDIT: dpkg-reconfigure shows no error:

dpkg-reconfigure nvidia-l4t-bootloader
Starting bootloader post-install procedure.
Update bootloader completed.
Reboot the target system for changes to take effect.

But it keeps failing after reboot.]

Do you mean you cannot tell if this OTA is successful or not but just notice there are some problem running Argus?

I guess the disk space is the reason we didn’t reproduce this issue since we always re-flash the board before doing any test. Let me try this on our device first.

Yes, I didn’t notice other problem except some locks or crashs with argus, but I was able to workaround these.
I have just noticed a few days ago after an aborted install of some software leading to modules failing to be found…I just noticed an error and found the bootloader package status.

I cannot tell if tho OTA had been successful, but I doubt it was. Furthermore, I notice the following:
