Well, I just installed Wiring and the SFE libraries on my Vista desktop and I still received the same timeout error. Does anyone know what the baud rate the board downloads at? I am using a pair of modified XBee series 1 Pro units to download through (which download fine to my standard Arduino Pro 16 MHz) and they need to be tuned to the download baud rate, right now I have them set at 57600 baud, is that the correct download rate?
Thanks!
The bootloader baud rate is 57600 bps for the mega pro 3.3V.
Does the uploading work through a wire connection?
I’d love to try, I’m wondering the same thing but I do not yet have an FTDI cable because this had worked fine in the past. I may have to purchase one sometime soon for debugging, but I don’t see why this shouldn’t be able to work, it’s really confusing me why even on Windows it refuses to upload code and times out.
Sorry everyone for the delay. I have found a fix for *nix platforms, but you will need to burn a new bootloader. Here are the files if you have a programmer:

If you don’t have a programmer, contact techsupport at sparkfun dot com and we will either get you a new board or have you return your current board to be reflashed.
