Mecanique's bootloaders have always served me well in the past, no problem with them. I haven't the 4685 one, but I'm pretty sure if you purchased MCSP in the past, Dave will be able to build you a custom one in a snap.


Mecanique bootloader will work only with MicroCode Studio plus AND/OR using the MCLoader application. There's still a .DLL available in case you want to build your own custom pc software.


There's also the Tiny PIC bootloader route
