我正在为 stm32f4-discovery 板制作 DFU。
我的 DFU 使用的是由 STM32CubeMX 生成的项目。
但当我使用由 STM32CubeIDE 生成的项目时,主程序无法运行。
我采取了以下步骤:
首先,在 system_stm32f4xx.c 中
#define USER_VECT_TAB_ADDRESS
#if defined(USER_VECT_TAB_ADDRESS)
/*!< Uncomment the following line if you need to relocate your vector Table
in Sram else user remap will be done in Flash. */
/* #define VECT_TAB_SRAM */
#if defined(VECT_TAB_SRAM)
#define VECT_TAB_BASE_ADDRESS SRAM_BASE /*!< Vector Table base address field.
This value must be a multiple of 0x200. */
#define VECT_TAB_OFFSET 0x00000000U /*!< Vector Table base offset field.
This value must be a multiple of 0x200. */
#else
#define VECT_TAB_BASE_ADDRESS FLASH_BASE /*!< Vector Table base address field.
This value must be a multiple of 0x200. */
#define VECT_TAB_OFFSET 0x8000 /*!< Vector Table base offset field.
This value must be a multiple of 0x200. */
#endif /* VECT_TAB_SRAM */
#endif /* USER_VECT_TAB_ADDRESS */
在STM32F407VGTX_FLASH.ld中
/* Memories definition */
MEMORY
{
CCMRAM (xrw) : ORIGIN = 0x10000000, LENGTH = 64K
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K
FLASH (rx) : ORIGIN = 0x8008000, LENGTH = 992K
}
在STM32F407VGTX_RAM.ld中
/* Memories definition */
MEMORY
{
CCMRAM (xrw) : ORIGIN = 0x10000000, LENGTH = 64K
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K
FLASH (rx) : ORIGIN = 0x8008000, LENGTH = 992K
}
