It's simple to rig up the required electrical interface and attach it - say - to the parallel port of a standard PC. However, to make any use of it, you have to understand which data to send and how to interpret the results. This requires signing a NDA with IBM / AMCC / Freescale. Assuming you get the required information, it then means quite a lot of hacking to get some working code that interfaces with a standard debugger like GDB. And you will not be able to share your code with others, as the NDA explicitely prevents you from implementing it in any form of open source software. You will completely on your own there. In the meantime the BDI user has completed 5 more real projects. Go for a BDI.
