Re: PIC32MZ Bootloader Panels Memory Size?
The 16K is at the top of the second boot panel, and it would be hard to access it with one space. With the combined linker script, there would be (80K * 2) - 0x100*2 (Config Space) -16K = 146944.
The extra was probably because of the space between the boot flash panels.
If you're willing to go through a little headache, you could set up the 16K space as a separate section in the linker, and put specific files there.
All told, keeping out of the config spaces, there should be 163328 bytes of usable boot space.
