Optiboot?

Okay.. So I received my new, spare Sanguinololu board today from Botronicz. It cam with a ATMega1284P pre-programmed with Sprinter and Optiboot bootloader. From a hardware point of view it's identical to the Sanguinololu w/ATmega1284p I've been using. However, the bottloader is different. I want/need to program my own version of Marlin RC2 on this but I'm getting this error from Arduino when I attempt to upload the firmware: "avrdude: serial_baud_lookup(): unknown baud rate: 250000".

The Botronicz board came with a page of instructions for changing the boards.txt file to allow "upload in any version of Arduimo IDE" and I did the specified steps. I suspect this has something to do with the Optiboot bootloader in the Botronicz board which is different then the ATmega bootloader I've been running in my current board.

Does anyone know how to fix this so I can upload my firmware?

Thanks.

Apparently, the problem has to do with changing the upload protocol. If I leave it a STK500v1, I get the above baud rate message. If I change the upload protocol to "arduino" as instructed by Botronicz, I get a new message: avrdude: Can't find programmer id "arduino".

This makes sense because there is no programmer defined for "arduino"...

How can I fix this? Is this a problem because of optiboot and a non-standard baud rate???

Solved (I think)...

I replaced the hardware/tools folder in Arduino 0023 with the hardware tools/folder from Arduino 1.0 and that lets me program with the "Arduino" protocol.
