problem with arduino on breadboard atmega 328 avrdude: stk500_getsync(): not in

I want to upload a sketch on a breadboard like this: http://arduino.cc/en/Tutorial/ArduinoToBreadboard

Everytime i want to upload iget this Error :. :

Binäre Sketchgröße: 2.648 Bytes (von einem Maximum von 30.720 Bytes) avrdude: stk500_getsync(): not in sync: resp=0x00

I searched forums for help but install the driver and look for TX/RX bringing no help =(

Sorry for my bad English :blush:

What chip are you using to handle the serial communications to the bread board? Ex: Ft232R...

Can you see the USB connection (or the appropriate connection) under 'tools' and then 'serial' port? You should see something like "dev/tty/cu-usbmodem" etc...

If not, confirm that you can see the serial communications chip. On a Mac, go under system profiler and look at the USB connections (Command+R refreshes the list). Otherwise, on a PC there should be a device manager that you can look at.

If you can see the device there but not in the Arduino IDE, then you may need to install the correct driver.
