make debug how to break into the debugger?

[TorstenRobitzki]

Hi,
on MacOs 13.6, I can start a debug session, using make debug. Once GDB started, I can use the usual commands to inspect things. After starting the CPU using c, I want to break into the debugger, to inspect the value of some peripherals, so I'm pressing ctrl-c and I see the prompt of GDB. But now, no matter what key I'm pressing, I always get the question whether I want to end the debug session or not, when pressing a second key:

Program received signal SIGTRAP, Trace/breakpoint trap.
0x00003888 in _skip_0 () at /Users/todi/bloomlife/zephyr-workspace/zephyr/arch/arm/core/aarch32/cpu_idle.S:137
137     _sleep_if_allowed wfi
(gdb) s
quit
A debugging session is active.

    Inferior 1 [Remote target] will be killed.

Quit anyway? (y or n) EOF [assumed Y]
ss

In the example session above, I've pressed the s-key two times.

Is it possible to use make debug under Mac OS or do I have to setup the debugger on my own?

best regards
Torsten
