TX2 HDMI display not working at boot

I have an HDMI display issue on Jetson TX2 with Linux Tegra 4.9.299-l4t-r32.7.3+gff65a92ec55e.

HDMI display shows boot log right after reset, but for some reason, HDMI is powered down before Linux is started.

Then dmesg keeps repeating “blank - powerdown” messages, similar to issue Jetson Nano continuously prints tegradc tegradc.0: blank - powerdown

If HDMI display is connected after Linux has started then it works, similar to issue TX2 not booting up with HDMI connected - #50 by WaaallEEE

Is this issue able to be reproduced on devkit? Also, have you tried other kind of monitors?

3

I can reproduce this on Jetson TX2 Developer Kit with three different HDMI displays. My distro is Boot to Qt 6.4.3.

4

sorry that I have no experience with Qt6.4.3. Please flash your devkit with jetpack and see if monitors can work fine at this setup first.

5

I tried to reproduce this also with Jetpack version but then found out that NVIDIA SDK Manager support is only for Ubuntu 18.04. Do you know if it’s possible to flash Jetson based SW to TX2 from command line?

6

Hi,

What host are you using?

7

I have Ubuntu 20.04 and 22.04 and also Windows 10 and 11.

8

sorry that only ubuntu 18.04 can flash tx2.
