I copied the image jetson-nano-sd-r32.2.1.zip and flashed into a MicroSD card using Etcher.
My first boot up was successful, i was able to see the setup page, completed the setup process in the Ubuntu.
After that Jetson Nano rebooted, and i could not boot up anymore.
WayneWWW suggested I use sdkmanager to re-flash the Nano (I used manual mode when prompted). Tentatively this looks to be working (I’m in the middle of it right now). For me it has been a big job because I didn’t have a suitable Ubuntu lying around and ended up building a machine out of parts, and even burning a DVD (!). Still, in the end… The Nano is showing video again when before there was no HDMI output at all. Yay! I’m still learning about sdkmanager but it seems to have re-programmed my Nano from the ground up, including some very low level stuff. My Nano didn’t even have any serial output so I thought it was properly dead.
I have not been able to boot my jetson nano with a similar issue. I followed the steps in the jetsonhacks serial console tutorial (changing the minicom serial port set up etc) but no log is given after powering on the jetson. Does this mean the jetson itself is not functioning?
