I don't see that LED flash at all. Is that connected to the serial line for the atmel processor? Yes update fails, can't find serial /dev

Also I assume you mean for the start button that the contact was shorted together. If so it is not nor is any other button. Is there a schematic somewhere?

Not sure which row but here is a pic

hi kite, i seem to have a similar problem, it says no controller when the pi boots up in retropi and when in the console I only have /dev/ttyAMA0. Is there any fix that you've found?

Thanks
