Jetson nano boot up screen shows several [ OK ] messages and nothing happens afterwards

[user137452]

Hello, I am working with a robot called “LIMO”. This robot was developed by AgileX which is a Chinese robotics company. It runs on jetson nano. The OS was Ubuntu 18.04 LTS. You can look at details here. Since I am working on a project with it, I decided to backup the micro SD card the robot had. After I had done backing up, jetson nano boots up but it shows some warning messages and the screen blacks out. After a while, screen suddenly shows several messages containing [ OK ] in the front. Then nothing happens and I’m stuck. I have no idea what is causing it.

Please, take a look at them and suggest solutions if possible.

I wanted to provide 2 pics, but this forums limits a new user post only 1 pic.
This is how the 2nd pic would look like:
[ OK ] Started Network Manager Script Dispatcher Service.
[ OK ] Created slice User Slice of gdm.
[ OK ] Started User Manager for UID 120…
…
[ OK ] Update UTMP about System Runlevel Changes. System Runlevel Changes…[ OK ] Started NVIDIA Late Init Script. [ OK ] Start…

Some of the messages before this will help greatly. Is there any way you can get a full serial console boot log?

Also, how did you perform the backup? It is looking like the SD card content may have been corrupted, but without the full boot log we can’t be certain. More information how the exact method of backup would help, including information on the host PC.

Hey, I realized I was running low on storage. Getting stuck in boot up screen, in my case, meant there wasn’t enough space for GUI applications to start. The solution was to press Ctl+ Alt+F3. This shifted me to a working CLI and I manually deleted some bulky files. After that sudo reboot was successful.
