Jetson nano is stuck at the login page on the serial debug console

[abdosalm555]

I was using jetson nano that had a small accident (it was being used on a drone that crashed). on trying to boot up the jetson nano, the logo screen shows then a black screen is shown. I grabbed a USB to UART converter to get the log message and it shows that it waits for entering the login credentials. I enabled the local echo mode in minicom and send a new line character using the shortcut “Ctrl+j”. however, the jetson doesn’t respond and doesn’t show anything. Is there anything I am doing wrong?

I have changed the USB to UART converter, and the TX line is connected successfully to the jetson nano board. the following image shows that the jetson nano is working successfully. However, the monitor connected by the HDMI cable from the jetson nano doesn’t show but only black screen.

Hi abdosalm555,

It seems you are using custom carrier board for Jetson Nano on your drone.
What’s the Jetpack version in use?

From the screenshot of your serial console log, it can be booted successfully.
Please share the full dmesg as file here to check if there’s any error relating to display.
