Hi
I have a Jetson AGX orin
but there is no console output from microB usb， my PC did detect usb devices
in Device Manager(show 4 devices)，and I set baud rate to 115200
type C usb port(flashing port) works fine BTW

Can anyone help with this issue?

Best Regards
Kevin

Hi kevintseng83,

Are you using the devkit or custom board for AGX Orin?
What’s the Jetpack version in use?

Could you get the serial console log before?

Serial console should be available on the first ACM node. (i.e. /dev/ttyACM0).
You can refer to NVIDIA Jetson Orin AGX - In Board - Getting in Board - Serial Console for details.

Hi,

I’ve two Jetson AGX orin both devkit

One of them works fine, One shows nothing
all using JetPack 6.2, with same FW
the SOM from the left side could be modified，we didn’t get it direcly from NV.
Maybe it could related to some default setting?

Thanks,
Kevin

What do you mean about “the SOM from the left side could be modified”?

Please confirm you use the exact same power, USB-Cable for both devices to do cross-check to confirm if it may be caused from HW defect?

Have you tried using SDK manager to reflash the AGX Orin devkit to check if it could help for current issue?

not all of them can show console log
first Jetson AGX orin COM16 works on my laptop
But for second Jetson AGX orin,COM22 works
Is this the normal behavior?
and how can I now which one can print out console log including early booting log
(Before boodloader)?

Thanks

Yes, it is expected that only one console will show the log.

But we expect it will always be the same order of device that will print log. For example, /dev/ttyACM0 to print log on Ubuntu.

We don’t know how Windows decide the COM order here so cannot comment.
