 {{:dev:nab:v2:jtag:bbv3.jpg?200 |}}I think you can use any JTAG probe that's 3.3v compatible, if you have one. If you don't, I recommend the [BusBlaster v3](http://dangerousprototypes.com/docs/Bus_Blaster_v3_design_overview). It's a great board, versatile and cheap; oh ! and it's also open hardware and open source ! :-)  {{:dev:nab:v2:jtag:bbv3.jpg?200 |}}I think you can use any JTAG probe that's 3.3v compatible, if you have one.

-On of the best features of the BusBlaster is you can reconfigure the CPLD to emulate any FT2232 JTAG probe. I think it comes pre-programmed with a JTAGkey buffer logic, which should work fine for this application.+One of the best features of the BusBlaster is you can reconfigure the CPLD to emulate any FT2232 JTAG probe.

 _Note_: My BusBlaster (a v4 !) uses a KT-link buffer logic, because I needed the SWD capabilities for another application. If the following steps don't work, try to reprogram the CPLD with a KT-link buffer and try again ! _Note_: My BusBlaster (a v4 !) uses a KT-link buffer logic, because I needed the SWD capabilities for another application.
