Hi etracer, i know what you mean. I tried all you mentioned above, but still failed.
I remove the xbee to try uploading
even remove both jumpers, but still failed uploading..

(unluckily, i lost one jumper when i removed them once and once again.)  :(

BTW,how do you identify your atmega chip? i even didn't see it there.
that's why i said i didn't have the chip on the board.

etracer

Well I was actually replying to crisfuga who seems to be ignoring the advice.

But if you don't have an ATMega chip installed, then I have 100% confidence that you're not going to be able to upload a sketch. Your image post didn't work so I can't tell you for sure what you have (or don't have).

The chip on a standard Arduino is located as indicated by the yellow box:

I'm pretty sure i don't have that part....

etracer:
under this situation, do you know how to control and program the arduino xbee moduel? how to connect arduino with c++?

Well where did it go? When you buy a Duemilanove it comes with an ATmega168 (or more recently a ATmega328).

Without it it's like taking the CPU out of your computer (and about as useful).

Good thing you can always buy another:

The picture you posted shows a XBee module, plugged into a XBee shield which is plugged into the Arduino. So if you want to see if a XTmega chip is installed (and which one), you'll have to remove the XBee shield (by pulling straight up).

of course i did remove the two staff on the arduino.
but no Atmega.

crisfuga

Ok, I solved it!

thanks etracer and diya for your help. It was a stupid thing, part of the problem was that jumpers were not correctly connected, as etracer had said.



diya

yeah, got it.
i use another arduino board with Atmega168 and the blinking works..
Thanks everyone here, specially thanks etracer.
