Jetson Orin AGX: unable to see Orin from a Linux host through connected USB port

Hello,

I was able to see the Orin through a connected USB port from the host (/dev/ttyACM0 or something like that) and I could log in as a console (minicom -D /dev/ttyACM0).

However, after someone flashed the orin, I am unable to see it anymore.

$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

If I put the Orin in forced recover mode, I could see this :

$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 0955:7023 NVIDIA Corp. APX
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Letting the Orin boot to multi-user mode, I could not see it again.

$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Reflash the Orin with jetsam 35.1 package still could not fix this problem.
Except this USB console issue, I don’t see any other issues.

Could someone kindly point out how to reset the Orin to the manufacture default setting ?

Thanks!

You may need to explain specifically what you need a USB connection to do with Orin.
Force recovery mode is fine, and you can flash L4T. In general, you should use Orin next with a monitor and keyboard, or with serial console.

In case the graphic monitor is not able to display due to kernel and module update, we need the console to debug which is pretty reliable. Hope this plains it.

Hi,
Do you connect to the micro-B port on Orin developer kit? The port is for UART debug logs.

Yes, one end of the USB cable connects to the micro-B port on the Orin. This is confirmed. Thanks!

I used the USB Type-C port next to the 40-pin connector to connect to my computer and log in with MobaXterm in windows. It works very well.
The Micro-B port is only used by me to view prints.
Hopefully someone else can help you out.

Hi,
Please re-flash system image through SDKManager by selecting Manual Setup in step 1 and Runtime in step 5. And then do initial setup in first booting. See if this works.

And please ensure only one Jetson device is connected to the host PC.
