Failed to build STM32CubeMX project with error: In function `LoopFillZerobss': (.text.Reset_Handler+0x32): undefined reference to `main'

zy1191231587 · March 1, 2024, 6:02am

Hi,

I bought the P-NUCLEO-IHM03 development kit and wish to use vscode and PlatformIO to build and flash. I followed the official instruction to generate the motor control code by STM32CubeMX (Src, Inc, etc), and tried to build (compile) the project with PlatformIO but failed.

The error is:

Archiving .pio\build\nucleo_g431rb\libFrameworkCMSISDevice.a
Linking .pio\build\nucleo_g431rb\firmware.elf
.pio\build\nucleo_g431rb\libFrameworkCMSISDevice.a(startup_stm32g431xx.o): In function LoopFillZerobss': (.text.Reset_Handler+0x32): undefined reference to main’
collect2.exe: error: ld returned 1 exit status
*** [.pio\build\nucleo_g431rb\firmware.elf] Error 1

Does anyone have a clue on how to solve this issue? Please let me know if you need more info to identify the problem. I appreciate your discussion and help!

More info about the kit:
Control board: STM32 Nucleo G431RB
Power board: X-NUCLEO-IHM16M1

My working environment is windows 11.
Here is the main.c file generated by CubeMX:

You’re not converting the STM32CubeIDE project correctly at all.

include_dir is the name of the folder that you want to set as include directory. Not some build flag. So if you want it to be Inc, it’s include_dir = Inc, not include_dir = -I Inc. Same goes for src_dir. See documentation.

Next I see you still have “Drivers” etc. in the root of the project – if that contains the STM32HAL, CMSIS etc., then setting framework = stm32cube is wrong because then PlatformIO will try to pull in its own version of the STM32HAL, etc. Also only sources in src/ or lib/<subfolder> will be compiled, a folder like Drivers at the root of the project will be completely ignored.

Please use stm32pio as conversion program or see related topics like How to write build_flags in platformio.ini.

shadowthreed · March 22, 2024, 2:07pm

@zy1191231587
Have you resolved this problem?
I got the same error message today, do you know the reason now?
my platformio.ini as below:

[env:genericSTM32F103C8]
platform = ststm32
board = genericSTM32F103C8
framework = stm32cube

build_src_filter =
  +USB_DEVICE/APP/usb_device.c
  
build_flags = 
  -IUSB_DEVICE/APP/
  -IUSB_DEVICE/Target/
  -IC:/Users/Ssd/STM32Cube/Repository/STM32Cube_FW_F1_V1.8.4/Middlewares/ST/STM32_USB_Device_Library/Core/Inc
  -IC:/Users/Ssd/STM32Cube/Repository/STM32Cube_FW_F1_V1.8.4/Middlewares/ST/STM32_USB_Device_Library/Class/CDC/Inc

@maxgerhardt
I have the same question. Is my platformio.ini incorrect also?

maxgerhardt · March 22, 2024, 2:34pm

This isn’t the right syntax for that, it’s missing the <> around the source file at least (docs).

The -I flags also indicate that you’re trying to include sources from a whole other directory outside the project. Something is majorly wrong here. Please try and use https://github.com/ussserrr/stm32pio or use the stm32cube reference examples at https://github.com/platformio/platform-ststm32/tree/develop/examples.
