How to introduce a new version of stm32cube:
|
||
|
|
============================================
|
||
|
|
|
||
|
|
Original STM32Cube tree structure has been modified to a minimum
|
||
|
|
structure for a better fit into Zephyr.
|
||
|
|
STM32Cube is divided into drivers and soc section, with:
|
||
|
|
|
||
|
|
drivers/
|
||
|
|
include/ contains Cube HAL/LL files from:
|
||
|
|
STM32Cube_FW_F1_VX.X.X/Drivers/STM32YYxx_HAL_Driver/Inc/*
|
||
|
|
src/ contains:
|
||
|
|
STM32Cube_FW_F1_VX.X.X/Drivers/STM32YYxx_HAL_Driver/Src/*
|
||
|
|
soc/ contains STM32 CMSIS files from
|
||
|
|
*STM32Cube_FW_F1_VX.X.X/Drivers/CMSIS/Device/ST/STM32F1xx/Include/*
|
||
|
|
*STM32Cube_FW_F1_VX.X.X/Drivers/CMSIS/Device/ST/STM32F1xx/Source/Templates/system_stm32f1xx.c
|
||
|
|
|
||
|
|
One file needs to be renamed:
|
||
|
|
driver/include/stm32f1xx_hal_conf_template.h
|
||
|
|
into:
|
||
|
|
driver/include/stm32f1xx_hal_conf.h
|
||
|
|
|
||
|
|
|
||
|
|
In order to enjoy ST CMSIS definitions:
|
||
|
|
*CONFIG_HAS_STM32CUBE should be defined
|
||
|
|
*stm32yyxx.h should be included in soc.h
|
||
|
|
**E.g.: #include <stm32f1xx.h>
|
||
|
|
|
||
|
|
In order to use STM32Cube HAL, these files should be compiled:
|
||
|
|
In /ext/hal/st/stm32cube/Kbuild :
|
||
|
|
obj-y += stm32yyxx/drivers/src/stm32yyxx_hal.o
|
||
|
|
obj-y += stm32yyxx/drivers/src/stm32yyxx_hal_rcc.o
|
||
|
|
obj-y += stm32yyxx/soc/system_stm32yyxx.o
|
||
|
|
Plus add HAL driver file (when needed):
|
||
|
|
obj-$(CONFIG_SERIAL_HAS_DRIVER) += stm32yyxx/drivers/src/stm32yyxx_hal_uart.o
|
||
|
|
|
||
|
|
|
||
|
|
Additionally, in order to use STM32Cube LL (when needed):
|
||
|
|
*include stm32yyxx_ll_usart.h in soc.h
|
||
|
|
**E.g.: #include <stm32f1xx_ll_usart.h>
|
||
|
|
