Jetson Nano Development kit is not working

[pugazhazhagan8]

I’m using the Jetson Nano development kit. I had a monitor connected via HDMI, one sensor connected to a USB port, and another sensor connected to the GPIO pins. While working, the power suddenly went off. It came back after about an hour, but I’m not sure if the Jetson Nano is functioning properly. The sensor connected via USB is no longer working, and there’s no display on the monitor. However, the sensor connected to the GPIO pins is still working.

Hi,

Please record the serial console log

Thanks

Thanks for the response. I followed all the steps mentioned in the video. I’m using a Jetson Nano B01 connected via a TTL converter, and I’ve also set the correct baud rate. However, after running the command ‘sudo minicom’ and then powering on the Jetson Nano, I’m not seeing any kernel logs in the minicom terminal. Also I checked with multimeter, I’m getting 3.3V in the jetson.

Hi,

How do you set up your device?
Do you connect TTL to RXD, TXD, GND pins?

Some commands you could refer:

# find the ttyACM
ls /dev/ttyACM*  
# If ttyACM0 
sudo minicom -D /dev/ttyACM0 -8 -b 115200

Thanks

Herewith I have attached the reference images.
After giving power to the jetson It will be like this.

I have connected TTL to RXD, TXD and GND of Jetson J50 header

Hi,

Do ls /dev/ttyACM* show other Serial Device.

Thanks

[pugazhazhagan8]

Yes, I did this. But I can’t able to find any serial device.

[pugazhazhagan8]

These are the only serial device it shows

Hi,

It’s right to connect with /dev/ttyUSB0to get the serial log.
Could you make the device in recovery mode and flash again?

Thanks

[pugazhazhagan8]

Hello,
Could you please share any reference video for this (to make device in recovery mode).

Hi,

We have official doc for how to put jetson nano in recovery mode:
