  • I've just updated my perfectly working board to this because the IDE advised it, and then used save() to flash the code I wrote to the board, and now the board is no longer showing up in the USB list on the IDE and when I use various cables to get into bootloader mode I get a blue solid and red light which occasionally pulses blue then goes red and blue solid and bright...
