non-stop mode in GDB on linux.

Hello,

My question regards debugging with GDB on linux.

I have a system with a real-time control thread and a secondary non real-time thread that I use to check system status.

During debugging I'd like for my debugger to stop the control thread in which I have a breakpoint, but keep my other thread running so that I can see the machine status.

Now in GDB this is possible using the non-stop mode, however I cannot seem to set the non-stop mode. WHen I go to the gdb console, set non-stop on, gives me an error that it does not work.

My question is, how can I enable non-stop mode in my debug session.

Any help would be appreciated.

Regards,

Jan Jaap
