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
