I'm currently developing a (simple) kernel using Qemu for i368. I was using a normal makefile and had debugging via GDB into Qemu working perfeclty The I moved to CMake and for some reason I can only hit breakpoints when my code is already in a breakpoint.
I also can't pause, the feedback I get from the debug window is the pause was succesful When setting a breakpoint it tells me Attempting to bind the breakpoint
A hint may be that when I stop the debug session, I get a popup from vscode saying timeout

Pause response
<-- C (pause-67): {"command":"pause","arguments":{"threadId":1},"type":"request","seq":67}
--> R (pause-67): {"type":"response","request_seq":67,"success":true,"command":"pause","body":{},"seq":1321}
Response when setting a breakpoint:
--> E (output): {"type":"event","event":"output","body":{"category":"console","output":"1: (340258) Send Event AD7BreakpointErrorEvent\n"},"seq":1327}
1: (340258) Send Event AD7BreakpointErrorEvent
--> R (setBreakpoints-69): {"type":"response","request_seq":69,"success":true,"command":"setBreakpoints","body":{"breakpoints":[{"id":4,"verified":true,"line":73}]},"seq":1329}
--> E (breakpoint): {"type":"event","event":"breakpoint","body":{"reason":"changed","breakpoint":{"id":4,"verified":false,"message":"Attempting to bind the breakpoint....","line":73}},"seq":1331}
If I type stop in Qemu terminal then vscode stops and I can set breakpoints again.
