Power LED will not light up


I recently purchased a Jetson TK1 dev board, and it is not powering on.

The problem started when I accidentally overwrote the libglx.so file (the graphics driver).

After i did that I was trying to fix the problem from this thread: https://devtalk.nvidia.com/default/topic/775070/embedded-systems/notice-on-apt-get-upgrade-libglx-so-corruption/

But while trying to fix that problem the fan quit spinning and the power LED quit lighting up.

So now when I plug it in the fan does not spin and the power LED does not light up.

However, the board does get warm when I leave it plugged in for a few minutes.

Is this definitely a hardware issue that I need to investigate with a multi-meter to determine if an electronic component is fried, or is this possibly a software issue I could fix without soldering?


Probably if serial console shows nothing it is a guaranteed failure. I’d say the odds are failure, but you really don’t know without serial test. If you have no way to test serial port output I’d call for RMA.

Well, if it is still getting warm without actually being on/etc, id try powering the fan with 5-12v externally (or even try using the onboard sata power plug, which doesnt have power until a few seconds after boot)

heres the pinout for that sata/molex power plug: http://i.imgur.com/TXBhhXD.png
and heres the one for the fan: http://i.imgur.com/Zks2u0P.png

So now that we know its not over heating…
Does anything show up on HDMI?
Do you have a serial cable so you can monitor that?
Is there any critical data on it or can you just re-flash it?

        • (i believe there are instructions here, or on nvidia’s website on how to clone/backup a jetson’s image so that you can restore it, IFF you have critical data/etc)

If the power led doesn’t turn on when you press the power button (and there is power coming from the power cable) then it sounds like a HW issue.

Even without any SW running on the Jetson you can check if the SOC starts up:

  1. Connect the micro USB cable
  2. Connect the power cable
  3. Press and release the power button
  4. Press and hold the Force Recovery button
  5. Press and release the Reset button
  6. Wait >2 seconds
  7. Release the Force Recovery button

Now if you run “lsusb” on your PC you should see the Jetson in the forced recovery mode:

Bus 002 Device 050: ID 0955:7140 NVidia Corp.

If you see that, then the SOC is running.
