Having trouble with uploading the program to my seeed studio board, is because of the bootloader not programmed in the atmega2560. Having tried several times, finally worked it out.
follow the step according to arduino official website .
http://arduino.cc/en/Tutorial/ArduinoISP
here is my step to used arduino uno to burn the bootloader onto ADK：
1. download the arduino1.0 IDE
2. connect the uno to PC with USB wire, tools->board->arduino uno
3. open->arduino ISP ,upload to arduino uno.
4. connect the ADK to uno , add a 10 uF capacitor between reset and ground on uno , according to the picture . ( uno ISP<-> ADK ISP ,uno D10<->ADK ICSP reset)
5. tools->board->arduino mega 2560 or AKD
6. tools->Programer->arduino as ISP
7. tools->Burn Bootloader
Howl 
in step4. uno ISP ADK ISP ,uno D10ADK ICSP reset ?
or
uno ICSP ADK ICSP but uno D10ADK ICSP reset ?
thanks
uno D10ADK ICSP reset, means the RST on ADK must connect to the P10 on UNO. I am not sure what kind of ADK board you are using.
but if you leave your email, I will send you some pictures , you will be clear if you see the picture
請教一下,在第四步
uno ISP ADK ISP ,uno D10ADK ICSP reset 是否有筆誤?
是否是uno ICSP ADK ICSP
但uno D10ADK ICSP reset 是何意?
