How to solve "Break at address "0xnnnnnnnn" with no debug information..."?

[White_Fox]

Hi guys

My software compiles fine. But if I try to run or debug it, it ends up with this message:

Break at address "0xf3af4804" with no debug information available, or outside of program code.

The console output is this:

Does anyone have an idea how to solve this? I'm just out of any ideas.

Ok, I do not know what went wrong, but I could solve it with that way:

The project was generated from CubeMX. I just savecopied my source code and header files, and deleted everthing except the .ioc file from CubeMX.

After this, I just let CubeMX generate the project again. Pasting the source code and header files again and it works now fine again.

It is the big hammer method, but it is fast if you do not need to set up much extra stuff.

It just means the processor faulted at some address outside the scope of your source code.

Say it popped the bytes from an ASCII string in the PC or LR registers, ie 0x454E4E36. Or you're executing in ROM, ie 0x1FFFxxxx

Debug it, look critically at the code it has to execute, starting from Reset_Handler, perhaps disassemble and disect the code if necesary. Turn off "Run to main()" and step your way there from the code that executes first.

Inspect the Stack, try to unpick the call tree.
