nRF Connect Breakpoint -> FATAL ERROR: Platform external interrupt

[Ingfu]

Hi,

I'm developing with nRF Connect SDK v2.9.0 in VS Code. I followed the exercise l1_e1 from the intermediate course. When I debug with breakpoints and the first breakpoint is hit, everything is fine. When I continue execution, the application crashes and the TF-M terminal shows

FATAL ERROR: Platform external interrupt (IRQn): 0x00000041
Platform Exception:

I use the nrf54L15 DK with cpuapp/ns target. What's the problem?

Hi,

Does the sample work fine when you just flash it?
Aka: Is the issue only seen when debugging?

Yes, the example works otherwise

Is this a breakpoint you set manually? If yes, where?

Also, can you try the same with the Zephyr/hello_world sample?
