Debug Arduino stuck in delay routine

[MystikReasons]

I created a simple Arduino UNO project with the Built-in GDB simulator.

I followed your tutorial: https://visualgdb.com/tutorials/arduino/ and everything worked fine.

But if I want to debug the project and I jump across the delay(1000) routine, the debugger gets stuck.

If I remove the delays, it works fine.

Is this a limitation of the built-in GDB simulator?

PS: If I set the breakpoint under the delay routines, the debugger will never trigger the breakpoint (see attached screenshot).

Hi,

Sorry, the built-in gdb simulator doesn’t work well for ARM targets and cannot be recommended for any practical scenarios. It is only usable for basic low-level tests (e.g. quickly checking that the ELF file can load into gdb and has the necessary debugging symbols).
