This is with the ATmega328 chip in. is this from the chip? because i also made sure Im setup on the right COM port Im stumped  


Again it's usually about the serial baud rate that the bootloader in your 328 chip is expecting.
Do you know what baud rate your 328 chip is expecting? The default for a 328 in IDE version 13 is 57,600 baud. My 328 purchased from Fundemental was burned in as 19,200 baud. So to work with IDE 13 I had to edit the 328 section of boards.txt and change 57600 to 19200 and then all worked fine.

PS: And of course I assume you have selected the 328 board from the IDE tools/board menu?

I have tried both 57600 & 19200 rates as for the Board selection in the IDE it is set to Arduino decimal or Duemilanove. Still nothing seems to work. :(

Board selection should be set to:  Arduino W/ ATmega328

Try that and see what happens, but you may still have to flip the baud rate around unless you know for sure what you 328 is set to.

I don't think my IDE has that setting "arduino W/ ATmega328, but now i am having trouble starting the IDE. It says Arduino.exe has encountered a problem and has to close. I re-downloaded the Arduino v13 from the site and still nothing happens. I am running windows vista home prem (I hate it just an FYI :) ) What do you think i should do to fix these errors?

Ok i found out what it was. Vista was running windows defender and it would not allow Arduino IDE to launch everything is all set and I can upload to the board now. I Thank you for all your help :D


Thank You

Actually we are working on seeeduino v2.1, with  Atmega 328!
