I've been looking for a few days to find info about this in the net. I downloaded the AVR Studio 5 and bought an AVRISP mkII from the Atmel store to follow the steps they explain on his website to block the security bites. The thing is that when I connect the Arduino Mega with the AVRISP mkII to my computer I can't lock the security bites on AVR Studio 5 cause that option doesnt exist for the ATMEGA2560 as ATMEL show on the tutorials.... So I have no idea how can I do that!!
The idea is to avoid anyone to access the code saved on the flash memory. Anyone knows how this can be done??
That will be much appreciated.
