Hi there,

I was modifying the bootloader to implement a blinking light when in bootloader mode so to signal the user that he/she can upload code, and I noticed a strange behavior:

the double tap on reset function does not yet work reliably, although I found out that trying to program a sketch using the virtual serial port of the HACK in sketch mode results in resetting the board, and unplugging and replugging it back shows that the board has fallen back to bootloader mode.

So, although I cannot yet get the double-tap-on-reset function to work reliably, this method works and is repeatable with no fuss. Which is a win after all.

Cheers,

Mick
