Cant upload to my other FARADUINO boards...

Hello, i have been hapily working with a FARADUINO board within the arduino environment, and all is well with the first board. I have 3 others but these will not allow me to upload code to them. I get the following errors

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

note the code will upload to the other faraduino board. The boards do show up as connected in device manager and are showing as com7 and com 8

Thanks in Advance


faraduino is just an arduino uno type board but with a built in motor driver ans servo section..
