Jetson TX1 HDMI problem

Technical Programming
1

Our team has an Nvidia Jetson TX1 that i am trying to learn how to use for auto. I am having a problem though. Every time i try to boot it up with the HDMI cord plugged in, the monitor turns on, but the command line says “hdmi: No EDID change. No userspace active. Using cached mode to initialize dc!” and freezes. After about 1-2 minutes it reboots. The Jetson has been flashed and has worked on other hdmi devices. The monitor im using for it is a Dell sp2208wfp monitor. It only works when i unplug the HDMI cord and let it boot, and then plug it in. Has anyone else had this problem? Any help would be much appreciated.

I encountered a similar issue on my Jetson TX2, but the problem I faced was that the HDMI to VGA adapter was drawing too much power, so all I had to do was plug a separate power source to adapter.

If you are going directly from HDMI to HDMI, many people have discussed the issue as seen here: https://devtalk.nvidia.com/default/topic/1003956/jetson-tx2/tx2-not-booting-up-with-hdmi-connected

There are quite a few posts on the NVIDIA forums regarding similar cases.

I hope this helps

My team has a Jetson TX1 and we never encountered this issue before. We used JetPack 3.1 and 3.2 on it.

From doing a google search on the error, it appears that your problem could be due to a bad HDMI connection, either due to the cable or monitor. Our monitor is an Acer and it appears to be from the last year or two, if not new. The monitor you are using was made 10 years ago. Have you tried connecting your TX1 to another monitor?

Haven’t seen this particular issue but HDMI can be finnicky and picky about monitors and adapters. Not all HDMI is the same and sometimes we are talking about a connector and other times about a specification and other times about an encryption scheme and other times about a port.

You’ll have better luck on the Nvidia Developer forums than you will on CD with this kind of issue. I’d look at a different monitor first and see if you can replicate it there.

Are you using the power supply that came with the TX1? If not try it, I had some weird issues with HDMI when I had a subpar power supply.

There are different protocols for HDMI, some don’t autodetect properly, particularly prior to version 1.3a where termination requirements changed.

I’ll echo other’s remarks by saying you will get better advice from NVIDIA’s forums.

I had the same issue today. Here’s a brief of what I did.

  1. Connect the Jetson TK1 to a router via ethernet.
  2. Find the IP of the Jetson and SSH into it. (I did it with an android phone, use Putty on windows if you want to.)
  3. Hit “ls” and you should see a folder named “NVIDIA-INSTALLER.”
  4. “cd NVIDIA-INSTALLER” then “sudo ./installer.sh”
  5. Restart jetson 2 times after giving an interval of 1 minute atleast each time.
  6. ???
  7. Profit

This is what I did, although not logical, it worked. Hope it does for you too!
