Can someone direct me to where the pin mapping takes place in the core libraries. To clarify: The pin numbers referenced by the ChipKIT bootloader are different to the pin numbers on the PIC32 itself, for obvious reasons. But I wish to alter some of the mappings and I cannot find where this takes place. Thanks.

It's done in the variants files, the Board_Data.c and Board_Defs.h files. This is on a per-board basis (thus the naming of the variants folder) because it's different for each board.
What board are you using, and what type of remapping are you interested in?

Thanks for the info. I am using a Max32 and have built a number of add on pcb's with extra functionality eg RTC, ethernet, RS485, GPS, GSM, infra red, RS232 and am now busy laying it all out onto one single, 4 layer, board that incorporates the PIC32. I'm coming across some clashes that I will be able to resolve by changing some of that mapping. I am also busy with some code in mplabX that I plan to load onto the same board and there I can only reference by pic32 pin number so having the mapping table available will help. Thanks again.
