* Hi :-) What is your typical debugging (SWD/JTAG) workflow? I tried debugging my stm32wb55 board with probe-rs and a JLink right now, and I get weird results. Basically, it complains about a missing core configuration. Using the ST-LInk it somehow works, however there is no clear yellow line marker when I want to stop at a breakpoint, so I am not sure if it actually stops: [discussion](https://github.com/probe-rs/probe-rs/discussions/3145) I don't know probably I configured probe-rs the wrong way, maybe you could give me a hint. In my other C firmware projects I am always using openocd and the cortex-debug extension for debugging. There are also some efforts to support defmt: [PR](https://github.com/Marus/cortex-debug/pull/880) Do you have experiences using openocd or maybe even probe-rs (with gdb) with the cortex-debug extension? Greetings, Christian
