I can see the serial data light blink once when I issue the
Nothing else happens and shortly I get a NoResponseError.
Now, I know that I'm compiling an edge_test and trying to run it on the Nano. It doesn't have anything connected to GPIO14, whereas it looks like the Edge has a pushbutton. The instructions for flashing the Edge say to press the A14 button. I tried shorting GPIO14 to ground on my Nano, but it doesn't help.
Is there something special I need to do on the Nano to get it to flash new code?
