Thanks Windell.

You’re right of course about the chip – the Peggy 2.1 uses the ATmega168-20PU chip.  But we have the same problem whether we’re trying to upload to a Mega168, mega2560 or Duemilanova.  And we have the same problem when we use the Arduino IDE on a Mac or PC.

In every case, we’re using a USB cable to transfer the code from the PC/Mac to the Arduino board.  In every case, we can transfer the code successfully to an Uno or Nano board.  In every case, we get the “avrdude: stk500v2_getsync(): timeout communicating with programmer” error message when we try to upload to a 2560, 168, or Duemilanova Arduino.
