I was surprised at how easy the project went together. I compiled the boot
loader with the low block default.
I moved my application to start at 0x0400. It required changing some org
statements. The 3 vectors instead of 0, 8 and 18 are now 400 408 and 418.
Nothing else was touched. I set the pc boot load program baud rate to equal my
normal com1 baud rate of 57,600.
It came up running. Really slick.
I may look into doing something with the RX break detect to trigger a jump to
start. The app note has suggestion on that.
Good luck with it! Start by downloading AN1301 from Microchip. It provides the
folders for both PIC16 and PIC18 and all the needed files. The PC program is
setup to get the job done. I used my ICD3 from Microchip.

I plan to file post it after I confirm operation.
See my other file post (extended math for PIC18).

A project that I'm working on may need a bootloader. I hope you let
the list know how it goes and what not to do as you work on this.

I plan to implement an assembly language bootloader for the PIC18F8722
microcomputer using AN1310 as a guide.
It seems straight forward. Anyone gone down this path before with comments or
