I was referred to this forum by the Nvidia Customer Care group after asking for help with my Jetson Nano SDK. I am just learning about robots and Linux and my software/computer skill are ancient. I am an old retired electrical engineer so I have a technical background. I built the Nano Jetbot and ran the basic-motion jupyter notebook successfully and then a day later when I sat down to run another notebook exercise, the Jetson Nano module would no longer boot up. I removed the nano from the jetbot to see if I could boot up with a JetPack4.3 image SD instead of the jetbot SD. It didn’t start. I do have a green power light and that’s it - no wireless WiFi or HDMI monitor video.
I have had a second Jetson Nano 4GB SDK in operation for a few months that is running nominally. So I swapped my power supplies/cable, SD image cards, monitor hook-up that I know works with other unit to eliminate the external hardware. The result was no change - same as before. So I think the problem is with the boot-up configuration or an internal hardware failure.
I did a lot of reading on the forum but frankly I cannot follow the in-depth technical documentation and processes.
So, I would greatly appreciate the help anyone is willing to provide. What would be most helpful for me would be a simple step by step process that I could use to get started.
