Protect Flash memory on ATMEGA2560 (SOLVED)

-

hi,

i've been looking few days find info in net. downloaded avr studio 5 , bought avrisp mkii atmel store follow steps explain on website block security bites. thing when connect arduino mega avrisp mkii computer can't lock security bites on avr studio 5 cause option doesnt exist atmega2560 atmel show on tutorials.... have no idea how can that!!

the idea avoid access code saved on flash memory. knows how can done??

that appreciated.

thanks!

afaik, atmega2560 has same security features atmega328; bytes/bits trying set (or pages of tutorials looking at)?
note "protected" settings won't protect against bootloader being able read code.

as5 has bad reputation; should upgrade 6.1.

you want delete bootloader , set non-bootloader lock bits (lb1, lb2) 0: "further programming , verification of flash , eeprom disabled in parallel , serial programming mode. boot lock bits , fuse bits locked in both serial , parallel programming mode."
