I would like to program an arduino leonardo board with atmega32u4 on win8.1 x64. I have the latest AVRdude. I installed the necessary drivers, after reset it can be enter programming mode, and I can program with arduino studio. But now, the avrude gives this:
C:\>avrdude -carduino -P COM5 -n -p m32u4 -b19200 -v
avrdude: Version 6.1-svn-20131205, compiled on Dec 5 2013 at 17:34:22

avrdude done. Thank you.
I tried also with 57600 baud. Any idea? Thanks.
