CCFLAGS not applied to project source files

I’m trying to use FreeRTOS on a Nucleo-F303K8 board. The steps I’ve taken so far:

Create empty project in STM32CubeIDE using Freertos
Copy the FreeRTOS files to PIO project
Reorganize files so it compiles without altering src-flags
Update build-flags, so headers are correctly included

Source code available on github:https://github.com/MarkMan0/STM32-Serial-Parser/tree/freertos

At this point the compilation fails with the error:

C:\Users\Mark\AppData\Local\Temp\ccezaArj.s: Assembler messages:
C:\Users\Mark\AppData\Local\Temp\ccezaArj.s:330: Error: selected processor does not support `vstmdbeq r0!,{s16-s31}' in Thumb mode
C:\Users\Mark\AppData\Local\Temp\ccezaArj.s:332: Error: instruction not allowed in IT block -- `stmdb r0!,{r4-r11,r14}'
C:\Users\Mark\AppData\Local\Temp\ccezaArj.s:352: Error: selected processor does not support `vldmiaeq r0!,{s16-s31}' in Thumb mode
C:\Users\Mark\AppData\Local\Temp\ccezaArj.s:354: Error: instruction not allowed in IT block -- `msr psp,r0'
*** [.pio\build\nucleo_f303k8\src\port.o] Error 1

I’ve read that this can be due to incorrect FPU configuration, so I’ve looked at the build command of STM32Cube(it compiles over there), and they use hardware FPU, with the following flags:
--specs=nano.specs -mfpu=fpv4-sp-d16 -mfloat-abi=hard -mthumb

So after further research and trial-error I created an extra_script in platformio.ini, with the following content:

Import("env")
env.Append(
  LINKFLAGS=[
    "--specs=nano.specs",
    "-mfpu=fpv4-sp-d16",
    "-mfloat-abi=hard",
    "-mthumb"
  ]
)
env.Append(
  CCFLAGS=[
    "--specs=nano.specs",
    "-mfpu=fpv4-sp-d16",
    "-mfloat-abi=hard",
    "-mthumb"
  ]
)
print(env.Dump())

The script runs ?correctly?, but the error still persists. The verbose output is the following:
pio run -v >out.txt

The flags --specs=nano.specs -mfpu=fpv4-sp-d16 -mfloat-abi=hard -mthumb are not used for the files below ..., and I can’t tell why.

I don’t know if the flags would fix the compilation error for the FreeRTOS, but I believe they should be used during compilation.
Did I miss something, do I need to specify to use these flags for my files too?

Instead of

github.com

MarkMan0/STM32-Serial-Parser/blob/940723e0b9e94a99ce29c397d99e67bff6ea9fb0/platformio.ini#L26-L26


      
          extra_scripts = extra.py

Try

extra_scripts = pre:extra.py

Also, it is not necessary to add all the -m flags in there. That can be done with

build_flags = 
   -mfpu=fpv4-sp-d16
   -mfloat-abi=hard
   -mthumb

too. Only

Import("env")
env.Append(
  LINKFLAGS=[
    "--specs=nano.specs"
  ]
)

is needed.

This fixed it:
extra_scripts = pre:extra.py

I also had to delete the "--specs=nano.specs" line, and had to keep the rest of the extra.py file as was, because when I specified the rest of the parameters in the .ini file only, it still produced some weird error messages.

Anyway, it’s working now

Thanks for the help!
