avrdude: error: programmer did not respond to command: select device

Hallo,

ich habe Problem mit meinem AT90CAN128. Ich möchte diesen MC mit AVR 
Eclipse programmieren.

Aber während upload habe ich das Problem getroffen:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
avrdude: error: programmer did not respond to command: select device
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Unter "AVR Target Hardware" habe ich schon AT90CAN128 mit 16000000 
ausgewählt.

Kann jm mir sagen, was das heißt???

Vielen Dank im Voraus!
