avrdude done.  Thank you.

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

And? Is this a question or some kind of information?

You cut off the command from top of the log. It can provide useful info an you should also post which board and what are you trying...
Did it ever work?

You should read the forum rules first.

Hi,

are there any connections in the TX and RX pins ???
