Problem with auto reset
Arduinos with auto reset capabilities(i.e. Diecimila, Duemilanove) will likely need to have the auto-reset functionality disabled. When a program(i.e. avrdude) connects to a serial port the DTR line is set and unset, which triggers a reset. Avrdude (as of v5.6) connects to the Arduino before it has booted. The problem may manifest itself with the error message "avrdude: stk500_getsync(): not in sync: resp=0x15". The problem may also manifest itself withe the error message "avrdude: verification error, first mismatch at byte 0x0000 0x3F != 0x00". This happens when Avrdude connects to the Arduino bootloader on the host. The Arduino bootloader supports a subset of the same STK500 protocol that Mega ISP uses but always returns 0x00 when reading the lock bits.
