PIC32 development under Linux and Mac OS X

Maybe this is interesting.

With the US$40 UBW32, you can use the toolchain (C32) and the
USB bootloader to try out PIC32 under Windows/Linux/Mac OS X.

Microchip actually created a new SourceForge site to host their
open source projects.
http://sourceforge.net/projects/microchipopen/

The first project is ccompiler4pic32, Community version of Microchip
Technology's GCC (GNU Compiler Collection) based MPLAB® C
Compiler for PIC32 MCUs. Hopefully they will make a community
version of GCC compiler for PIC24/dsPIC30/dsPIC33.

For programmer, PICkit 2 can be used with pk2cmd.

Now the main missing piece is the debugger. There is some
work on OpenOCD side to use common JTAG debuggers
with PIC32.

Some status updates on this front.

According to the OpenOCD mailing list, support of PIC32
debugging and programming is now kind of in place.
All basic functions within gdb should be working, including
software/hardware breakpoints. Some works are still needed to
get it fully working.  For example, it is said that all flash can be
erased and/or programmed. Still no chip_erase command.
And data transfers to/from the target are still slow.

When this is done, you can use cheap parallel port based
Wiggler or those USB JTAG tools for ARM (FTDI2232 based,
R-Link, J-Link, etc) for PIC32 debugging/programming.
