I was recently working with my Jetson Nano 4GB developer kit with the latest jetpack installed in it and I was using it to make an object detection bot. On 1st May 2021, I was trying to run my semi-finalized code and tested it running on my bot. It was working when I ran the code for the first time with TightVNC. I tried to run it again and the code started for few seconds and I lost connection to TightVNC. I thought there was some disconnectivity issue but I found that TightVNC was not getting connected. I tried to connect jetson to the Monitor screen and I was getting long bootup messages instead of the Nvidia logo and normal ubuntu GUI. I tried to use a different SD card with a new jetpack but when I did that I was only able to see the first page of the license agreement because the mouse and keyboard plugged in were not working (my mouse and keyboard works well with my laptop). I also tried to use a serial cable to run it with PuTTY but it is not working as well.
