So, I've just been given a Netduino and followed the instructions to get a Visual Basic 'Hello World' flashing LED going. When deploying it to the board I got an error something like 'you're trying to deploy xxx at version 4.2 to the Netduino which is at 4.1'. So I reflashed the Netduinot to 4.2, but now it does nothing except sit there with both the blue and white LEDs on. I think it needs the bootloader updating as well, but the SAM-BA 2.1 program will not run on my windows 7 PC. It no longer shows up in the deployment tool and windows wanted to install a camera driver! I need a bit of help please! Thanks in advance.
