--- Comment #12 from Chernov Sergey aka Klen <klen_s at mail dot ru> ---
Despite the fact that I am also a little in kurma how it all works, I can n=
ot
say anything definitively.
Due to the fact that microcontrollers sometimes began to have more than one
core, a situation arose that the infrastructure for remote debugging should=
 be
fundamentally expanded ( cpu cores, multithreading etc ), probably not done
with just skewers and patches. Judging by the code 11.1 - it works correctly
but "in the old way". In 11.2, they started trying to fix it and broke
everything :) It will probably take a lot of work to make it elegant and
reliable again on different targets
I tried your changes on trunk code - it also fixes the problem... but
unfortunately gdb now crashes when communicating via MI protocol with eclip=
se
IDE. in the console everything is fine and correctly debugged.
