Re: backup installed firmware?

Reviving this very old subject...

I'm trying to backup the firmware currently on my MakerFarm Prusa i3. I'm using the following command:

avrdude.exe -C ..\etc\avrdude.conf -p m1280 -c avrisp -i 10 -P com6 -U flash:r:original-firmware.hex:i

Note: There's a colon followed by o in the command above, don't know how stop it from turning into a smiley...


I'm getting the following error:

avrdude.exe: stk500_getsync(): not in sync: resp=0x00

There's a tip here about pressing the reset button, but can I actually access it? It's burried below the RAMPS.
Note: I also tried without the '-i', with the '-F', and higher baud rates (I'm using 250000 on Pronterface, so tried that too).

Please advise ;-)
