The not enough memory build error for the ME18 Bootloader example has returned, but this time, it's on the ME18APARD board.

Looks good, thanks!

I corrected the Bootloader example's memory configurations to their actual length - which should be enough room to prevent oversize build errors in the future.

For future reference, thee ME18 Bootloader example previously assumed the two flash instances had the same flash page sizes and lengths which is incorrect.

Flash 0: 3MB total, 16KB per page
Flash 1: 256KB total, 8KB per page

I'm not sure why Eddie decided the Bootloader program size is two pages long... But expanding the bootloader program shouldn't be an issue as there's more than enough memory in the ME18 to accommodate for larger programs.
