Hello Ole,

nice to hear from you again!

In the meantime, I revived and fixed some issues in
 http://openocd.zylin.com/#/c/3881/

It works soemhow with on a nucle_l053 and I can see the threads. However
the hand does not happen on L053. On f3 discovery, where th thread hang
happens, OpenOcd has the old problems with halting the target and the thread
list does not make sense. I have to dig deeper. 

And maybe I have to activate and understand SWO...

Bye
