Because I needed to bootload over Ethernet, I didn't want to try to fit
Ethernet code in the boot section. Microchip does have an Ethernet
bootloader for the 18 series, but not the 24. I think they are using tftp
and putting it in the boot section. With my Ethernet approach, no special
application is required to bootload. Just run a browser. So, the
bootloader uses the application, which the bootloader is going to
overwrite. So, that's why I need the external flash. Some place to store
the new code before I overwrite my application. The external flash is an 8
pin SPI part, not too expensive (M25P16) that I use in various other
projects.
