I found the interface to open ocd to be very slow for flashing, basically useless. It might have improved since my last test. Check it on a regular basis.

I did communicate with Microchip about the debugger and they provided me with documentation on programming using the PE. As for debugging I didn't get a straight answer but will look into adding mips debugging to my debugger. JTAG MIPS debugging should be
simple.

Take note that this is work in progress, it could be a while as right now I spend my spare time on the AVR32 Pascal Compiler and getting my funtoo and Ubuntu lazarus up and running on the Odroid U2. PIC32 is my next target. I will use the Raspberry Pi,
Odroid U2 or Odroid X2 as the debugger platform. Rasphberry pi might need a command line debugger, graphic is a bit slow. Odroid U2 doesn't have GPIO access, perhaps the USB port might work fine.
