Upgrade to JP5.1.1 failure

[ethan.frantz]

I tried to upgrade my Jetson AGX Xavier dev kit from JP4.4 to JP5.1.1. To upgrade I’m using SDK Manger on an Ubuntu 20.04 machine.

The first time I tried the kernel install seemed to work but SDKM got stuck when trying to install the SDK. It couldn’t create a ssh connection to the Xavier. I could ping 192.168.55.1 but if I manually tried to ssh, the connection was refused. At the same time the HDMI monitor plugged into the Xavier would show the boot splash screen, but went black after that and wouldn’t show any image.

After reading some of the post on the forum, I deleted all the downloads (~/Downloads/nvidia and ~/nivida/nvidia_sdk) from my host machine, put the Xavier in recovery mode and reflashed. This time the install appeared to complete (include the SDK) but the screen was still black.

Now I can ssh into the Xaiver. But in the /home/nvidia directory, I only have the ‘Desktop’ directory. I don’t have Documents, Downloads, Music, Pictures, Public… When I type on a keyboard or move the mouse connected to the Xavier, the screen wakes up but never produces an image and goes back to power saving mode.

Attached are the output of dmesg, Xorg.0.log, and the serial console.

Any ideas?

Hi ethan.frantz,

@ethan.frantz

I’m using SDK Manger on an Ubuntu 20.04 machine.

Are you using x86 based Ubuntu as your host PC?

From your log, it seems you can boot the AGX Xavier devkit successfully.

[   40.309365] tegradc 15200000.display: hdmi: plugged
[   40.334984] tegradc 15200000.display: blank - powerdown

There are some error logs in your dmesg.
Could you try using another HDMI cable or display to verify?

Could you also check if the following command help for your case?

$ export DISPLAY=:0
or
$ export DISPLAY=:1

A different monitor did the trick. Swapping cables on the original monitor didn’t help. This is kind of weird. I’ve been using the original monitor with Jetson Xavier for years.

I plugged back in the original monitor and again was unable to get an image. Based on this page, I used xrandr to change (reduce) the resolution of the original monitor and was able to get an image. (Original monitor is bigger, sharper and higher resolution). After playing around, full resolution is flaky but one step down seems to work.

Thanks
