I just got a new Jetson Nano P3450 4GB RAM NVIDIA Jetson Nano Developer Kit (945-13450-0000-100), by hindsight I formatted and flashed (balenaEtcher) a 128 SD Card with the jetson-nano-2gb-jp451-sd-card-image.zip which had the sd-blob.img (this was for the 2gb model) and then once plugged in and powered via the micro usb, it started and it went till the ubuntu desktop and after a minute or more it asked to reboot and I did and then it got stuck on the nvidia logo and does not complete loading. I later downloaded the jetson-nano-jp451-sd-card-image.zip which has the sd-blob-b01.img (the one for the 4GB model) and wrote that to the SD card and plugged that in hoping that it would boot and I could get it working , but its stuck on the nvidia logo screen.I cannot see what the loader is doing , it tries and goes black after some time but comes back to nvidia logo screen.
I thought it was something to do with the SD Card I tried three models toshiba 128 v30c3msdxc, lexar 128c1 and sandisk 32 utlra but still stuck on the logo and cant see what’s the issue.
I feel the first successful load and restart has written ??? something ??? to the board ??? and its stuck cause
the first image was for the 2gb one and not for the 4gb one ???
Is there any way to come out of this situation , I am in a windows environment at the moment.
Can I reset the board and if there is something that gets erased and try over again ?
Can someone advice on the steps in this case.
