How to fix "No source available for main() at ..." encountered while debugging ?

[Simon151]

Hi everyone,

I’m currently trying to debug my project. However, as soon as I start the debugger, I always get the following error message: "No source available for main() at 0x80048bc". I’m using a custom board with an STM32L4P5ZGT6.

Read and followed these threads: https://community.st.com/t5/stm32cubeide-mcus/how-to-solve-the-error-quot-no-source-available-for-main-at-quot/td-p/228420

and https://community.st.com/t5/stm32cubeide-mcus/debug-quot-no-source-available-for-main-quot/m-p/385835

I ensured I’m using the Debug build configuration and set Debug Level to -g3.

Any Ideas how to fix this?

Thanks in advance.

Simon
