Dual Core Debug on STM32H755

I'm developing a project with the dual-core STM32h755zi-q, but when I run the m4 core while debugging, I encounter the error, "Break at address "0xa05f0000" with no debug information available, or outside of program code." I've configured the debugging settings according to the documentation and video shared by ST. I'm currently working on the m4 core, and I'll switch to the m7 core later, but I'm not making any progress due to the error I mentioned above.I would like to express my gratitude to everyone who helped.

I'm seeing the same with an H757 device and IDE V 1.19.1.

The debugger loads the code and stops at main(), as expected. I can single step from there, but I get the message you reported if I run to a breakpoint.

The stack window shows:

[core: 3]( Suspended : Signal : SIGTRAP:Trace/breakpoint trap)

I get the same if I just hit run after loading with no breakpoints set.
