В тырнете нашел вот такой bootloader : скачать......

 Для того, чтобы скомпилировать исходник под ваш контроллер, нужно изменить 2 файла:

 processor 18F2480

 #define OSCF 20000000

 #define BAUDRATE 115200

и меняем конфиг , который нам нужен, MCLRE должен быть включен и припаян резистор между первой ножкой контроллера и +5В

Чтобы контроллер "уходил в boot" в своем софте для контроллера нужно делать команду сброса. Например :

Во вкладке "Reset" в приложении "ds30LoaderGui.exe" в поле "Command" нужно ввести ff;ff;ff;ff;ff;ff;ff;ff;ff;ff;ff;ff
