The raphberry pi could be made into a nice device for programming and debugging. The graphic sucks so a headless device would be more usefull. OpenOcd is too generic, cannot be fast. My approach is a dedicated programmer for the PIC32 using the PE from Microchip. For debugging I would use openocd until I get my gdbproxy working. Rasphberry pi is only $35 which is cheaper than JTAG programmers. Rasphberry Pi is actually very fast if you don't have the X environment to slow it down. Once I manage to get setedit to work on the command line I will no longer need the X interface. The latest development on turbo vision seems to have locked it into using X. I am digging into this to uncripple it. What I would like to have is something just like we use to have on Dos. My more interesting project is to have a full development system on an Odroid U2 or Odroid X2. The odroid is actually so fast that it rivals with some computers. It costs a little more, an Odroid U2 is $85, still cheaper than most JTAG programmers.
