Mike,
I was attempting to build the 16-bit FF for a dsPIC33EP256GP502-I/SP
because I was keen to have more SRAM than the dsPIC33FJ128GP802
offered. I think that I've got the correct header files included by
adding an entry to ff30.inc but have just copied the p33f_config.inc as
a starting point for a new p33e_config file. Presently I have the
following errors from the assembler.

BUILD FAILED (exit value 2, total time: 158ms)
It seems that the interrupt vector tables are a bit different. Any
suggestions?
Also, this MCU has more static RAM than will fit within the first 32k
address range.
I guess that I need to set appropriate boundaries.
Of course, these might also be just the start of many changes that might
be needed. Could you hazard a guess as to how many? I will accept an
answer of "too many", but I thought that I would just try my luck and
see if it was easy to get FF running on this chip.
Regards,
Peter Jacobs
