I don't undestand why I can program my 328P of my arduino board with de arduino IDE, but I can't do this with avrdude at cmd.
avrdude -p m328P -P com3 -c arduino -b 19200 -U flash:w:LedBlink.hex
The response is:
avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude done. Thank you
I read a lot of threads and tutorials and I think I'm writing correctly the commands.
What's the problem?
Arduino duemilanove, IDE: arduino alpha 0021
