文件目录

拷贝E:\Function_LIB\RTT_WORK\rt-thread\bsp\stm32\libraries\templates
下的stm32f10x文件夹（通用模板）
至E:\Function_LIB\RTT_WORK\rt-thread\bsp\stm32
与libraries同一级
修改stm32f10x文件夹名，自定义开发板命名stm32f103_Fire_MINI

注：路径rt-thread之前的可自定义，rt-thread之后的路径保持原有

Cube

E:\Function_LIB\RTT_WORK\rt-thread\bsp\stm32\stm32f103_Fire_MINI\board\CubeMX_Config
下运行cube程序CubeMX_Config.ioc，
修改芯片型号，配置系统时钟，配置外设引脚（仅串口外设）

生成代码后，E:\Function_LIB\RTT_WORK\rt-thread\bsp\stm32\stm32f103_Fire_MINI\board\CubeMX_Config路径下可仅保留这四个文件

SystemClock

将E:\Function_LIB\RTT_WORK\rt-thread\bsp\stm32\stm32f103_Fire_MINI\board\CubeMX_Config\Src中的main.c的时钟函数

  1. void SystemClock_Config(void)
  2. {
  3.     ...
  4. }

拷贝到E:\Function_LIB\RTT_WORK\rt-thread\bsp\stm32\stm32f103_Fire_MINI\board中的board.c中

board

在board.h中修改芯片flash和ram大小（256k和48k）

  1. #define STM32_FLASH_START_ADRESS     ((uint32_t)0x08000000)
  2. #define STM32_FLASH_SIZE             (256 * 1024)
  3. #define STM32_FLASH_END_ADDRESS      ((uint32_t)(STM32_FLASH_START_ADRESS + STM32_FLASH_SIZE))
  5. /* Internal SRAM memory size[Kbytes] <8-64>, Default: 64*/
  6. #define STM32_SRAM_SIZE      48
  7. #define STM32_SRAM_END       (0x20000000 + STM32_SRAM_SIZE * 1024)

注意：STM32F4芯片虽然RAM有192但是只有128可以用户使用，所以设置的内存大小必须是128，另外64是CCM仅CPU可以使用

Kconfig

修改E:\Function_LIB\RTT_WORK\rt-thread\bsp\stm32\stm32f103_Fire_MINI\board中的Kconfig

修改对应芯片型号

  1. config SOC_STM32F103RC
  2.     bool
  3.     select SOC_SERIES_STM32F1
  4.     select RT_USING_COMPONENTS_INIT
  5.     select RT_USING_USER_MAIN
  6.     default y

添加板载外设USB转串口选项

  1. menu "Onboard Peripheral Drivers"
  3.     config BSP_USING_USB_TO_USART
  4.         bool "Enable USB TO USART (uart1)"
  5.         select BSP_USING_UART1
  6.         default y
  8. endmenu

添加片上GPIO和串口驱动选项

  1. menu "On-chip Peripheral Drivers"
  3.     config BSP_USING_GPIO
  4.         bool "Enable GPIO"
  5.         select RT_USING_PIN
  6.         default y
  8.     config BSP_USING_UART1
  9.         bool "Enable UART1"
  10.         select RT_USING_SERIAL
  11.         default y
  13. endmenu

link

修改E:\Function_LIB\RTT_WORK\rt-thread\bsp\stm32\stm32f103_Fire_MINI\board\linker_scripts下的link文件

link.sct

  12.    .ANY (+RW +ZI)
  13.   }
  14. }

LR_IROM1和ER_IROM1后的第二个数字（0x00040000）为flash内存位数的16进制（2561024）
RW_IRAM1后的第二个数字（0x0000C000）为RAM内存位数的16进制（481024）

flash内存 = 0x08000000~0x0803FFFF = 256k
RAM内存 = 0x20000000~0x2000BFFF = 48k

SConscript

修改E:\Function_LIB\RTT_WORK\rt-thread\bsp\stm32\stm32f103_Fire_MINI\board中的SConscript文件

修改启动文件和芯片型号（根据cube生成的mdk工程修改）

  1. if rtconfig.CROSS_TOOL == 'gcc':
  2.     src += [startup_path_prefix + '/STM32F1xx_HAL/CMSIS/Device/ST/STM32F1xx/Source/Templates/gcc/startup_stm32f103xe.s']
