I bought the Jetson Nano Developer Kit 16G eMMC, and it was working great right away. However, one day I plugged it in and it wouldn’t boot up. The light and fan would come on, but nothing would be seen on the monitor. I was told to re-flash the eMMC with the commands in this link. However, the flashing process kept failing. See the log below
