Xavier NX no longer boots

Autonomous Machines Jetson & Embedded Systems Jetson Xavier NX

I was trying different SD cards and JetPacks and managed to cause my Xavier NX to no longer boot. I did not see any reset buttons on the device. When I apply power, the HDMI sends a “no signal” to my flat panel monitor. I also noticed the heatsink gets a bit warm but the fan is not running. The green LED near the USB port is lit.

Is there a recommended procedure to get boot messages or perform a hard reset?

Thanks,

do you have any working SD card? the best bet is to attach a serial port dongle onto your NX and use a terminal program to look at the console output on the low level boot. this was a trick i used to discover that my system wasn’t booting because the bootloader wanted a signed kernel.

to hook up the nx, here is a video, but ignore the arduio:

use something like this for the dongle:

anyhow, the boot console might give you a better idea of what is really happening.

This is helpful. The ADAFRUIT USB-to-TTL breakout cable looks like a good option to see if any boot messages are being logged. I just ordered one and should receive it in a day or so.

I’m still waiting on the breakout cable but was able to re-flash the Jetson and got it back to life using the SKD Manager running Ubuntu 18.04 on a PC via USB.

If you can connect the debug port and then he can see all the boot message from the console /dev/ttyUSB*

Yes, I received the ADAFRUIT adapter and can see the console messages. Like I mentioned, re-flashing the Xavier NX with the SDK manager fixed my issue so I am all set.
