Hi,

I am using STM32f413zh i build the code in release mode. After that i put break points on inside the code some places, None of the break point is hit. But i flash the binary file the code was running. Please give guidance for hit the code on main() or inside the code.

Thankyou.

So the debugger won't know what code addresses correspond to which source lines - as discussed above.

If you want to be able to do source-level debug, then you need to enable the debug info.

Uncheck "run to main​", and walk in from Reset_Handler.

Instrument Error_Handler () and HardFault_Handler ()

Make sure BOOT0 is pulled LOW.

Press STOP in the Debugger, observe where the MCU is stuck, or whatever.​

Yes, I pause the code while running that was not reach any error handlers, The code was running properly i am also able to see the led indications also perfectly run as per logic.

While i debug the code i am able to see the below screen. I don't know why that was not hit in inside main().

again, If you're in Release mode, is debug information being created?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

One reason for this could be that the release mode uses a different code optimisation, so that the lines with the break points have been optimised away. They are then still in the source code, but no longer play a role for the code execution.
