I've been trying to sort my uncommunicative puck without any joy. There has been a slight change. Now when I try to program with the tiny bootloader I get an error back immediately "Could not connect to COM5".
Just to be sure am I trying to do this correctly. Load up tiny bootloader and get it ready to go. Switch on epuck. Click "Write" in tiny app and try to hit reset button as soon as possible ? A possibly related question. On the main board there is a second button that looks like the reset button. It's hidden under the board with the speaker on. The button is almost directly under the bluetooth. What does this button do ? It wouldn't be so bad if I could blame myself for writing a dodgy controller but its one I downloaded from the e-puck site. I'm a bit confused as to which one it is, it is one of sercom, advanced sercom, or swiss_demo. I'd guess at one of the sercoms because none of the other program selections start up any of the demo programs.
