Hello ! Is somebody may help me ?! I am starting with arduino, and i want to know how lock bootloader and have possibility to update my code with crypte sketch. In my research i found "Dmitry bootloader" but it is difficult for me to use it ! May somebody help me ?
Is anyboby used AVR universal bootloader ? Please :-/
Locking code and secure bootloaders are somewhat contrary to the "open source" philosophy of Arduino, and I haven't seen anyone post information on it. If you must lock your code, it's much easier to use a device programmer and get rid of the bootloader entirely.
