RESOLVED 13 December:
After a couple of days of frustration, this is the best advice for Windows 11 users not experienced with Linux other than running containers in WSL2. It is best to get two USB or external drives with size at least 64 GB, or even buy a small PC to install Linux on it. The small PC will avoid you might kill/ format your Windows installation as I did.
If you have 2 USB’s you install first ISO on USB 1 and then boot from that USB to install on USB 2 your final image. This is because the ISO comes with only 8GB and lacks storage for the 30 GB on packages you need to flash the Jetson.
Then boot with the USB 2 or your dedicated laptop (better), and download with firefox the SDK manager and say you want to install it, or double click after downloading. You need credentials for NVIDIA dev site to get the download.
If your Jetson is never installed you need to force it into installation mode with a jumper.
Click on the the ‘linux’ look alike of the Windows Start button and start SDK Manager. You need to sign in again. The SDKManager will see your Jetson. Now run through the wizard and finally your flash. This flashing can takes hours (maybe depending on the speed of the USB HDD drive I used). Half way before 50% it want to install components through the network. So make sure your SDK Manager and Jetson are on the same network.
Connect a HDMI monitor to the Jetson and start a terminal from the ‘start’ button or ALT-F2 to open commands in Linux. Then type ifconfig to look up your ip number. Enter that ip number in the SDKManager and check the options based on your carrier board supplier. Mine is Seeedo and for that manual and preconfig without anything else, as it is already in forced mode and first installation.
Latest step is how to get the software on the Jetson. I guess additional SD is needed as the Jetson complained about low storage. I will update when I know this. I want to run dotnet (C#) as inherence with ONNX. So that is the next challenge.
Hope this helps.
I miss clear guidance for Windows users. Easiest way would just be an .msi to run SDKManager :-) natively under Windows…all those command line commands :-(.
To my understanding you cannot run WSL to install SDKManager. I got tons of errors, but seems file system and flash will not work. So I run on Docker Desktop an Ubuntu 20.0x ? version. No idea how to download the files on such image without a GUI.
I bought a production module with 16 GB internal memory and SD card. But I read somewhere that booting from SD will not work for this type of PCB.
So a lot fuzzy information instead of a clear manual -(.
