Uno boatloader and Avrdude

Hi all I am trying to get Avrdude to talk to the boatloader on the Uno with these lines in my makefile

DEVICE = atmega328p PROGRAMMER = -c stk500 -P com38 AVRDUDE = avrdude $(PROGRAMMER) -p $(DEVICE) -B 10 -F

I get a continues timeout. What am I doing wrong or is this not possible?

Are you using a JTAG ICE/STK500 device? Can you leave out the -b baudrate setting in this case? If you are not using some ICE, and just trying to talk to the bootloader on the Uno, set the baudrate and use the "arduino" programmer ID.

Yeah, I discovered the Arduino tag. It seems to be working ok now, thanks. Now I need to call Avrdude from my C# application :astonished:
