My nvidia jetson nano 2gb developer board is stuck in a bootloop. I flashed the latest image intented for the 2gb developer board and I went through the settings. After I somehow couldn’t log in, I turned off the power and flashed the image again. From there it has been stuck in a bootloop and sdk manager can’t find the device because it doesn’t provide a ttyACM0 anymore (it did before).
The log starts with:
