Loading to Main Board

I am attempting to load the code to a Sparkfun main board, no shield (we have one but are in the middle of trouble shooting some issues).  The load time took several minutes and at the end I received the following error:

 

avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x64
avrdude: failed to write flash memory, rc=-4

 

Any ideas on what to do?  Already checked the main list of error problems and we are following them all.  Any help is appreciated.

    Try pushing the reset button on the APM just after the message, "Uploading X bytes of Y maximum" appears at the bottom of the arduino IDE.

     

    Also make sure your board is set to the 1280...I think this is in the tools menu of the arduino IDE.

    You went through ALL of these troubleshooting steps? How, for example, are you powering the board?
