Just got my board and was trying to bring it up. It took me a while to find instructions on bringing it up. I used the “mindb_dd.tar.gz” image and put that image on an SD Card. I powered it up and windows registered a new usb com port. I attached to this com port but didn’t see any output. Should I use a different image or am I doing something wrong? It does look like it is booting up as I see a serial port enumerating and showing up as a serial port on windows.
