During Release build code not hit main()

[AFaya.1]

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.

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.​

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.

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

[AFaya.1]

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?

[AFaya.1]

NO.

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.
