Hi!

I was updating my Jetson and after rebooting, it stopped giving a signal from the display port. After waiting for 15 minutes, I reset it, but it didn’t improve anything. I took a laptop, installed Ubuntu 22.04 and the SDKManager, but the board is not detected. When I use lsusb and dmesg, it does not detect anything. The connection is done through a USB-A to USB-C cable, with the USB-C end of the cable connected to the USB-C port near the 40-pin header. Here are the results of lsusb:

jaumegtd@jaumegtd-HP-ProBook-650-G3:~/Documents$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 04f2:b595 Chicony Electronics Co., Ltd HP HD Camera
Bus 001 Device 002: ID 8087:0a2a Intel Corp. Bluetooth wireless interface
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Then I tried using a USB-A to micro USB cable, and it worked. I used minicom and screen to see what is happening during boot. Here are the log files for a normal startup and for when using recovery mode.

recoveryLog.txt (65.3 KB)
normalLog.txt (80.5 KB)

In normal mode, I can see that pressing ESC enters the setup mode, but unfortunately, the text becomes too garbled and I cannot see where the cursor is or what I am selecting. I tried changing the configurations of minicom, including disabling flow control, changing the speed, data bits, stop bits, etc., but it’s always garbled or showing unknown characters. What can I do?

EDIT: After trying again now I can navigate the setup mode, but I can’t see how to flash the SD
EDIT: I tried to stick a USB and try to boot it but it didn’t do anything

Is this a DevKit or a custom board?
We don’t have HDMI ports on DevKits.
Do you know how to put the device in force recovery mode?

This is a devkit.
I meant a displayport instead of HDMI.
I know how to put it in recovery mode with the buttons, also with the debug UART I can use reboot --recovery.

So you are sure it’s in force recovery mode, but still not detected by lsusb?
Have you tried with other USB cables?
Take a picture of your hardware setup.

After trying for the 1000th time, it worked and the sdk manager now detects it. How could I flash a new os, I would like to install ubuntu 22.04 from scratch
