I have a board with an ATmega328P connected to an FT232HQ.
I use an Arduino Uno for Arduino as ISP to program the boot loader into the target board.
I tel the IDE that I have an "Arduino Nano" with ATmega328, connect to the target board and select the new port.
I can upload a sketch just fine and it runs fine but if I try to upload again it fails with:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
But if I re-download the boot loader it will again let me download a sketch once...
Anyone have any ideas?
