For those who do not know - "Microchip pic32" - is a mips m4K core micro
controller.
If I remember correctly, PIC32 has limited very RAM (64K) and no external
memory interface.
I wish ! 32kb RAM. But it does have up to 512kb ROM.
You sure you want C++?
Absolutely. Used carefully C++ will help keep the app small and tight, and
I've got a pile of existing C++ code it needs to run.
You might look "upstream" from them and figure out where they got it from
(ie: From MIPS) perhaps they have subset of the Mips package?
Done...
Second, you'll need to look at your DEBUG options - they are not using GDB
- and there is *some* *limited* support for ejtag in OpenOCD.
I expect (hope ?) to use GDB via JTAG. Proof of concept here is using the
ICD programmer but the MPLAB stuff will never support C++...
Third, if I remember correctly gcc-pic32 has many #pragma hacks- that get
picked up by the linker later on - and handles the bare metal chip
initialization stuff.
Exactly; this is one of the reasons I'd like to rebuild their version
rather than move to a 3rd party version (the 3rd parties don't support the
Microchip extensions, leading to a different set of problems).

Thanks Duane !
