Stm32 + cmsis + spl

Hello! I try to build example ported rom Kail project for STM32F407ZGT6 devboard.

my ini file is:
platform = ststm32
board = black_f407zg
framework = cmsis
board_build.mcu = stm32f407zgt6
board_build.f_cpu = 168000000L
debug_tool = stlink
upload_port = stlink
build_flags =
build_type = debug

I have given from example files:
startup_stm32f407xx.s system_stm32f4xx.c stm32f4xx.h e.t.c

I found how to force PlatformIO use my stm32f4xx.h but files startup_stm32f407xx.s system_stm32f4xx.c always takes from framework folders .platformio\packages\framework-cmsis-stm32f4 and I got not functional project.

How I can force PlatformIO use my startup files?

I see in the latest version system_stm32f4xx.c in framefork missnig core clock init routine.
I try use self routine but it take wrong clocking freq…


if you want to avoid PlatformIO to compile the builtin files, you can let these point to invalid files so that the inclusion filters don’t “hit” any files. In the platformio.ini:

board_build.cmsis.system_file = invalid
board_build.cmsis.startup_file = invalid 

Of course you are then expected to have the sytem.c and startup.S file in your src/ folder.

Thanks a lot! It works! Clockings setup starts well.
