Even with a running OpenOCD, you need support files for your board, your CPU
and your debugger. Every time I tried for my problems, some of this support
was missing (or may be only obsure to me).

I use Blackmagic http://www.blacksphere.co.nz/main/blackmagic for STM32
debugging and put some effort in it to support more CPUs and boards and
documentation http://embdev.net/articles/STM_Discovery_as_Black_Magic_Probe.
It shows up as a USB serial device and and after "target extended
/dev/ttyACM0", "monitor jtag (or swd)" and "attach 1" I have connection to
the target cpu. No Host OS dependancy beside having USB CDCACM support. And
if needed, the CDCACM support can easyly be exchanged against normal serial

I just tried to start a discussion on the blackmagic mailing
list about thread support. Hopefully there is some outcome or helpfull hints
for that discussion.
