Hi

I have a Arduino Duemilanov "ATmega328P-PU" (2009) and I tryed to connect to it with avrdude.

avrdude -p m328p -P /dev/ttyUSB0 -c stk500v1 -b 19200 -F -u -U flash:w:test.hex

But it always tells:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding

Can someone tell my why it is not working?? I am using Fedora 11 linux. Can someone plz explain me how I can connect to my board plz.

Are you pressing the reset button at the correct time for the bootloader to respond?

The Arduino IDE does this automatically via the auto-reset function before handing off the uploading task to AVRDUDE. If you are using AVRDUDE in command line mode, then you have to force a reset manually, or have some scripe that toggles the DTR signal to the serial port.
