Jetson Nano triggers over-current in Recovery mode

Hello everyone,

Sorry in advance I may say stupid things as I am still a newbie.

I am trying to connect my Jetson Nano board to my host (Ubuntu 20.04). I have put the Jetson in recovery mode (I suppose, the LED is green, nothing is displayed on my monitor). Also, my board has plugged the power jack. I think I should also specify that jumpers are plugged on both pins of the J48 and pins 7 and 8 of the J40 header buttons. When I connect the board to the host with the microC/USB, if I look at the dmesg, I can observe the following error message:

[ 6111.020532] usb usb1-port1: over-current condition
[ 6111.048288] usb usb2-port1: over-current condition

I also provide you the result of my lsusb return:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 1bcf:2c88 Sunplus Innovation Technology Inc. Integrated_Webcam_HD
Bus 001 Device 003: ID 8087:0a2b Intel Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I read on another topic that using a HUB may solve the problem, unfortunately, I do not have one. Is the jack power not supposed to prevent the current use of the USB connection?

Best regards,
Hector

Sorry for the late response.

Is this still an issue to support? Any result can be shared?

Hi hectorfadat,

Are you using the devkit or custom board for Jetson Nano?
What’s your Jetpack version in use?

There would not be the serial console log output in force recovery state.
From the lsusb result on your host, it seems you are not in force recovery state.

Please short REC/GND and power up the board to enter into force recovery mode.
You will see nvidia device showed with lsusb command on your host PC.
