Jetson AGX orin 64G， After following the official tutorial to flash JetPack 7.2 version, the machine went black and could not boot up properly.
The reference flashing link is as follows：
Could you set up the UART serial and dump the log?
Want to check what is wrong there.
I have never set up UART serial debugging before and I’m not familiar with the operation steps. Could you provide me with a detailed guide on how to do it?
If you are using NV devkit, connect a micro USB cable to the micro USB port on your Jetson.
Connect the type A side to a Linux PC.
Check if /dev/ttyACM0~4 got appeared on your host side when Jetson is connected or not.
If there is, then use tools like minicom or picocom to open it. Then boot up your Jetson and copy all the logs to us.
(if you are not using NV devkit, then it could be different)
If I don’t connect the monitor, the error message can be found in the attachment: ttyACM0_no_display.txt
ttyACM0_no_display.txt (138.9 KB)
dpkg -S /lib/firmware/display-t234-dce.bin
nvidia-l4t-firmware: /lib/firmware/display-t234-dce.bin
You could try reinstall firmware that is error-ing in ttyACM0.txt.
sudo apt update
sudo apt install --reinstall nvidia-l4t-firmware
sudo sync
sudo reboot
After executing the following command, the screen still goes black:
‘’’
sudo apt update
sudo apt install --reinstall nvidia-l4t-firmware
sudo sync
sudo reboot
‘’’
The log is as follows

Simplest and perhaps best would be to flash your board again. It looks like Capsule update did not run.
This should be 39.2.0. Your log has UEFI firmware: version 36.4.4-gcid-41062509 built on 2025-06-16
sudo nvbootctrl dump-slots-info
Current version: 39.2.0
Capsule update status: 1
Current bootloader slot: A
Active bootloader slot: A
num_slots: 2
slot: 0, status: normal
slot: 1, status: normal
This might work. Put Orin in recovery mode
cd pathto/Linux_for_Tegra
sudo ./flash.sh --qspi-only
But to be safer do full flash again.
I have solved this problem using your method. Thank you very much.
