Jetson Xavier AGX Dev Kit (32GB) won’t power on correctly: power led turns on and then immediately off

Hi, we are a formula student team from Rome and we have got a Jetson Xavier AGX Dev Kit (32GB), we use it to run the autonomous system of our driverless car.

Unfortunately, our board doesn’t boot anymore: the power led turns on for about 1 or 2 secs and then immediately off (slightly similar to this topic). We tried to check also the serial console logs when powered up but no logs are shown. We can’t understand where is the problem.

In addition, the SDK Manager doesn’t recognize the board, so we can’t try to “reflash” it…

Do you have any ideas?

Hi SapienzaFastCharge,

Please check the dmesg output after plugging the device into the host PC to monitor any changes.
Additionally, could you verify if the device is in recovery mode by using the lsusb command? For more information, please refer to the documentation.

Thanks.

Thanks for your advice, we are going to check it on this saturday.

In the meantime, we can tell you that we tried to put the board in recovery mode yesterday with the buttons combination described in the user guide, but it didn’t work, it doesn’t power on.

Hi, unfortunately the dmesg output does not show anything…

In addition, we used the lsusb command, but the device is not detected so we are not able to verify if it is in recovery mode.

On the contrary, if we plug the board into the host pc using its micro usb port this is the output.

Hi SapienzaFastCharge,

Please try using the provided Type-C to Type-A cable from the dev kit, connecting the Type-C end to the AGX Xavier and the Type-A end to the host PC.
Then, run lsusb again.

Thanks

Hi, actually that’s what we did.

Perhaps we are not making ourselves clear, but here when we first tried dmesg and lsusb we connected the board as you said.

On the other hand, we also tried to use the micro usb port, just to do all the necessary checks.

Hi,

Thanks for the information.
Have you tried capturing the serial console log using /ttyUSB0, /ttyUSB1, /ttyUSB2, or /ttyUSB3 when the issue occurred? The default is likely ttyUSB0, but you should try the others to see if any information appears. Please capture the log from boot up until the issue occurs.

Thanks.

Hi, we have already tried it as well.

The fact that the board immediately turns off doesn’t allow us to capture the log from boot up until the issue occurs.

Hi,
have you tried long pressing the power button to see if anything changes?
If nothing happens, try replacing the power supply.

Thanks

Hi, we tried long pressing the power button, nothing changes.

The power supply doesn’t seem to be the problem: its led lights up green as expected.

Hi,
One more question: Did the AGX Xavier boot successfully before?
Let me summarize the steps you have taken so far:

  1. Connected a Type-C to Type-A cable to access /dev/ttyACM0 and set the device to recovery mode.
  2. Connected to micro USB port to dump the UART log from the Xavier during boot. Some logs might still appear even if the board’s power light is off, so please try again and share the results.

Thanks

Hi,

yes obviously, we have never had any problem with it, it has been something unexpected.

We have already tried it, literally no logs appear even if the board’s power light is off.

Hi,

In this case, we recommend proceeding with an RMA.
You can refer to this link for more information.

Thanks.
