CubeIDE not loading source code for makefile project while debugging

[gkowshik]

Hi All,

I have a Makefile based project that I imported to CubeIDE. I am able to build it smooth, however when i am trying to launch a debug window I am not able to see the source code and it only shows 2 buttons saying "View Disassembly" and Preferences tab.

Unlike the one's shown online I am not getting an option to load the source file by browsing my file system. What am I doing wrong and how to load this??

The below is my debugger view (I put a breakpoint at Reset_Handler hence the halt)

Please help me with the problem as it's very hard to debug with the assembly view. please note the view is not loading when the function is entering C files too, i.e., from Reset Handler the PC jumps to SystemInit which here is a C file but even for that I am not able to see the load.

Thanks

What version of GCC do you use to build?

Did you build with debug info?

What version of CubeIDE do you use to debug?

Show how you do the launch

What version of GCC do you use to build? - gcc version 10.3.1 20210621 (release) (15:10.3-2021.07-4)

Did you build with debug info? - Do you mean my optimization level? Yes, I had -O0 and added 

What version of CubeIDE do you use to debug? - I am using the latest version i.e., 1.16.1

Show how you do the launch

I created a new debug configuration by going to Run -> Debug Configurations

And to launch I simply clicked Debug As -> STM32 C/C++ Application and it was able to launch it.

No. You need a -g to include debug info in the ELF file:

https://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html#:~:text=Level%203%20includes%20extra%20information%2C%20such%20as%20all%20the%20macro%20definitions%20present%20in%20the%20program 

Default for CubeIDE is -g3:

Hi,

Thanks for pointing it out. I have now included it in my makefile. Here's my makefile for your reference, however I am still not being able to reference the source code while loading the elf in the IDE.

I have somehow solved this issue by selecting the MCU name in the Build settings, then when I put a breakpoint to a function that's in a C file, it didn't load the source code directly however it has now brought the button to search and load the source file.

@elif77 Thanks for the reply. There seems to be a mismatch in the cross referencing of the file path as my PC has WSL enabled and I need to add the mapping translations for the file path in the debug configuration. 

After giving the file paths and the mainly enabling "-g3" to the makefile I am able to get the debug views correctly. 

Thanks alot for your help, I will close this.
