I’ve been trying to get my Jetson Orin Nano to boot up so I can provide step by step instructions to replicate the issue reported in Overcurrent warning & reboot on 25W mode - #5 by DaneLLL . However, I am currently facing another problem where the displayport output is glitchy. I can see the screen clearly for a few seconds, but then the screen goes black. This problem did not exist last week.
This happens even when there are no programs happening.
It is a bit difficult to use the Jetson Orin Nano in this condition. I have tested the exact same DP cable & monitor on different power modes (25W/15W and 7W) and this issue has persisted. To rule out issues with the cable & monitor themselves, I connected the output of the Jetson Nano via DP and there are no glitches in the output.
To rule out any issues from interference on the displayport data I moved other cables away from it. Additionally, reduced the resolution to the lowest point possible (720x576 @ 50Hz). Flicker still persists.
So, I’ve obtained a delayCON 1m displayport-HDMI adapter. While the display is now limited to 1080p @ 50 Hz at least the display does not flicker and is usable. 👍
Considering this an interim solution: I really want the displayport to function. It is not possible to see the virtual console (CTRL + ALT + F3) with the adapter (display just goes blank with “No HDMI signal from device” on the monitor). 🥲
I’ve tried two different monitors, and two different displayport (dp→dp) cables. All combinations lead to no video output on the screen from the Jetson Orin Nano.
The delayCON cable (dp→HDMI) works, with stable repeatable output. I have already spent four work days trying to resolve the original issue, so I will consider this a good enough solution for me to continue. ✅
