Before my board is working ok, and accepts upload from Arduino1.0. However once I had a try on an ISP programmer with the board, and maybe I erased flash at that time (cannot remember what I did exactly…). After that, I cannot program the board any more
When I choose “Burn Bootloader” from Arduino, it responses: “avrdude: stk500_getsync(): not in sync: resp=0x00”.
What shall I do to recover the board to the original condition? Thanks in advance!
