another plus is that BDI speaks gdb.
For ARM openocd plus a jtag dongle (cheap FTDI based) is a really good
solution, unfortunately other arches are not so well supported. But I
had problematic cases where openocd did not work correctly in the past
(especially working with armv7 somewhere between 0.4 and 0.5). I think
these cases are sorted out but you may get other problems. Openocd
however is open source, so you just can fix it ;)
