Hello team. I am using Xavier DRIVE kit, got system no longer display anything from HDMI to the monitor after forced shutdown. Just because I accidental installed nvidia-jetpack using sudo apt-get install nvidia-jetpack the terminal got halted. Is there button for factory reset or how to recover from this situation? Thanks

Are you using DRIVE AGX devkit or Jetson AGX Xavier devkit?
The JetPack is for Jetson devic.
Can you figure out which one you have?

Dear @kaaa1202,
Please connect host <->target debug port using USB - USB cable and then use minicom/putty to connect aurix terminal. Aurix can be open at /dev/ttyUSB3

Please see DRIVE OS Linux for more details on minicom/putty usage

And Step 7 in page 11 of Quick start guide about host and target USB debugging port connection.

Thank you so much. I sucessed connection
sudo minicom -D /dev/ttyUSB3 -b 115200

(sorry in Japanese but yes I am able to access Aurix terminal)

Dear @kaaa1202,
Press ENTER in the above shared console to get access to aurix console. Once you get access, run poweroff and poweron.

In the console terminal, I can’t type poweroff and poweron eventho the cursor is blinking.

I physically turn off and on the power switch, that disconnect aurix terminal and ends up with like following.

Dear @kaaa1202 ,
Could you please check minicom port setting for /dev/ttyUSB3(aurix port).
Press CTRL + A followed by z and o and then select “serial port setup”

I would expect the above settings to work to get access to minicom console.

If you have physical access to board, please check disconnecting power supply(hard reboot) and restart the machine to see if it fixes. Note that, aurix should be accessible if we need to reflash the target if it does not get fixed after hard reboot.

Dear @kaaa1202 ,
Ok. You can access Tegra A with /dev/ttyUSB2 and TegraB with /dev/ttyUSB6. you can also connect LAN wire to target and can ssh to it. Please see https://docs.nvidia.com/drive/drive-os-5.2.6.0L/drive-os/index.html#page/DRIVE_OS_Linux_SDK_NGC_Development_Guide/Board/board_e3550.html#wwpID0E0CB0HA to ethernet connection.

Hello @SivaRamaKrishnaNV Could you assist next step, please. Thanks.

Dear @kaaa1202,
Do you want to reflash the target? If so, please check reflashing the target using sdkmanager and file a new topic in case of any issue with flashing. You can check DRIVE Platform Installation Guide with NVIDIA SDK Manager for flashing

@SivaRamaKrishnaNV
Back to my original question.

The System no longer display anything from HDMI to the monitor after forced shutdown. Just because I accidental installed nvidia-jetpack using sudo apt-get install nvidia-jetpack the terminal got halted.

So should I reflash the target or do you suggest any best way to recover in this situation?
