在STM32F401_CCU6/Src/tim.c中，添加以下代码

#include "sys_init.h"

#include "los_hwi.h"

VOID TimInit(VOID)

{

    MX_TIM3_Init();

}

VOID TimerHwiCreate(VOID)

{

    UINT32 ret;



    ret = LOS_HwiCreate(TIM_IRQ, 0, 0, TIM3_IRQHandler, 0); // 16: cortex-m irq num shift

    if (ret != 0) {

        printf("ret of TIM3 LOS_HwiCreate = %#x\n", ret);

        return;

    }

    HAL_TIM_Base_Start_IT(&htim3);

}

UINT64 GetTimerCycles(VOID)

{

    static UINT64 bacCycle;

    if (swCycles < bacCycle) {

        cycleTimes++;

    }



    bacCycle = swCycles;

    cycles = swCycles + cycleTimes * TIMER3_RELOAD;



    return cycles;

}

TimControllerOps g_cpupTimerOps = {

在STM32F401_CCU6/Src/usart.c中，添加以下代码

复制

VOID UsartInit(VOID)

{

    MX_USART1_UART_Init();

修改链接脚本，注意要先改完裸板程序中的.ld文件才能用裸板程序中的.ld文件替代LiteOS文件，在裸板程序的.ld文件中添加以下字段

/* used by the startup to initialize liteos vector */
_si_liteos_vector_data = LOADADDR(.vector_ram);

/* Initialized liteos vector sections goes into RAM, load LMA copy after code */
.vector_ram :
{
. = ORIGIN(RAM);
_s_liteos_vector = .;
*(.data.vector) /* liteos vector in ram */
_e_liteos_vector = .;
} > RAM AT> FLASH

注意要对着原来的liteos.ld文件将字段放在合适的位置。

修改配置文件
修改STM32F401_CCU6/Makefile文件，找到USER_SRC字段，在字段中添加跟其他语句一样的一句

$(LITEOSTOPDIR)/targets/$(LITEOS_PLATFORM)/Src/gpio.c
1
注意换行要用“\”符号添加在末尾，如果gpio.c已经添加，也可以将自己写的.c文件放进去，编译时会一同编译，USER_INC字段同理，为引入的头文件。

找到targets/bsp目录下的Makefile文件中

else ifeq ($(LOSCFG_PLATFORM_STM32F407_ATK_EXPLORER), y)
1
复制一份放置在下一个else ifeq前面，将其中的LOSCFG_PLATFORM_STM32F407_ATK_EXPLORER改成LOSCFG_PLATFORM_STM32F401_CCU6，STM32F407ZGTX_HAL_SRC改成

STM32F401_CCU6_HAL_SRC，修改完成的代码如下

else ifeq ($(LOSCFG_PLATFORM_STM32F401_CCU6), y)

保存后退出。
修改targets/bsp.mk文件，找到STM32F407_ATK_Explorer Options这个字段的代码，拷贝一份粘贴在下方另一个Opitons上面，修改其中的STM32F407_ATK_EXPLORER为STM32F401_CCU6，STM32F407xx为STM32F401xC，修改后代码如下

######################### STM32F401_CCU6 Options #######################
else ifeq ($(LOSCFG_PLATFORM_STM32F401_CCU6), y)
LITEOS_CMACRO_TEST += -DSTM32F401xc
HAL_DRIVER_TYPE := STM32F4xx_HAL_Driver

发表于 2022-11-28 23:59

修改targets/Kconfig.stm32文件，在config LOSCFG_PLATFORM字段下添加

default "STM32F401_CCU6" if LOSCFG_PLATFORM_STM32F401_CCU6
1
STM32F401_CCU6是文件夹的名字，LOSCFG_PLATFORM_STM32F401_CCU6字段是前面步骤中填写的字段。在下面的choice中的help字段中添加

STM32F401_CCU6
1
在往下的字段中添加代码

config LOSCFG_PLATFORM_STM32F401_CCU6
bool "STM32F401_CCU6"
select LOSCFG_USING_BOARD_LD
select LOSCFG_ARCH_CORTEX_M4
select LOSCFG_CORTEX_M_NVIC
select LOSCFG_CORTEX_M_SYSTICK
select LOSCFG_DRIVER_HAL_LIB

在tool/build/config中复制一份STM32F407_ATK_Explorer.config并重命名为STM32F401_CCU6.config，将STM32F401_CCU6.config中的STM32F407_ATK_EXPLORER替换为STM32F401_CCU6字段。将STM32F401_CCU6.config拷贝到LiteOS主目录下，并修改成.config名字。
