This is a devkit I picked up at GTC. The sd image is from your getting started page and is dated April 19th.
When I set it up the first time I plugged in a camera, but it didn’t boot. So I unplugged it and it booted. Then it rebooted midway through boot, so I got a better power supply. It booted up all the way, and I was in the middle of installing numpy when it froze. It wouldn’t boot after that. I checked the SD card and it was fried.
I bought a new card and a new power supply.
I was able to setup the first computer vision demo from jetpack. Then I tried setting up mxnet. The build was taking well over an hour on Friday, so I just left it. I came back Monday to the nano being “off”. After waking it up by wiggling the mouse and tapping the keyboard, it booted up and gave me the desktop and I was able to open terminal. I tested Python and to see if MXNet was working. It was not. So maybe it crashed mid-build. It stayed alive for about 2 minutes total, then rebooted. A lot. I flashed it again (this is a 128GB card). It rebooted after going through the setup process (new account, keyboard setting etc.) I didn’t even get to clone a repo. I switched to a 16gb card, flashed it and the same thing happened.
At one point I did some some “ubuntu recovered from a serious error” message, but it didn’t let me investigate before it rebooted.
I don’t know what you’re asking for with “dump below node after your reboot”…
