Jetson TX2 Shutdown during U-boot on Custom Carrier Board

Hello to everyone,

I have a problem with Jetson TX2 and a custom designed carrier board. We planned to use the module lent from the TX2 devkit for prototyping before buy modules for production stage.
We first power up and boot the Devkit, everything went fine as expected, the module comes already flashed, we configure Ubuntu for the first time and we are ready to go.

Then, we place the TX2 on our custom designed board, we receive these message on the serial monitor:

Welcome to Ubuntu 18.04.3 LTS (GNU/Linux 4.9.140-tegra aarch64)

As you can see the Jetson boot up and log us to Ubuntu.

We test Ethernet and it work, same as USB for recovery mode. Other peripherals has still to be configured, we didn’t change the Device Tree yet

After some time, while we didn’t do hardware modification, the jetson stop the boot process ad it autoshotdown
Here’s the log:

At [ 22.344621] the Jetson shutdown and the serial link is interrupted

The same thing happen while we put the TX2 in recovery mode.
boot as recovery mode
SDK Manager reveals the TX2 as adevice
After approx 20 second the jetson goes to reset.

Do you have any clue on how to debug this?

Thank you

Hi Mrco89,

I would suggest first going through the HW and SW bring-up checklists and make sure that attention was paid in bringing up the board.
Hardware Checklist
Software Checklist

During this process, either the root cause will be clear or you will gain more information, which will help up in debugging.

Since the Tx2 works on the Devkit , it is difficult for us to debug if the issue is on the carrier board
