基于HAL库用STM32CubeMx生成FATFs+sd+flash
用stm32cubemx生成初始化代码
这里用的是正点原子的f429开发板
- 初始化串口
- 初始化SPI5
- 初始化SDIO
- 上面初始化都使用默认配置
- 初始化PF6(FLASH的片选引脚)-》上拉，初始化高电平
配置FATFS
不用管,继续生成
刚忘记配置两个LED用来指示单片机状态有没有死机，
好了，继续生成
接下来移植正点原子的SYSTEM+MALLOC+W25QXX
下面我把修改过的代码贴出来
所用的头文件放到main.h里面去，方便使用
/* Private includes ----------------------------------------------------------*/
/* USER CODE BEGIN Includes */
#include "w25qxx.h"
#include "delay.h"
#include "sys.h"
#include "malloc.h"
/* USER CODE END Includes */
串口初始化代码里面先添加PRINTF的支持代码 别忘记了头文件的支持
#include "stdio.h"
/* USER CODE BEGIN 1 */
#if 1
#pragma import(__use_no_semihosting)
//标准库需要的支持函数
struct __FILE
{
int handle;
};
FILE __stdout;
//定义_sys_exit()以避免使用半主机模式
void _sys_exit(int x)
{
x = x;
}
//重定义fputc函数
int fputc(int ch, FILE *f)
{
while((USART1->SR&0X40)==0);//循环发送,直到发送完毕
USART1->DR = (uint8_t) ch;
return ch;
}
#endif
/* USER CODE END 1 */
这里是W25QXX的驱动代码。里面包括了spi的读写函数

上面的都是一些准备工作，其实到现在SD卡的文件系统已经移植完成了，因为生成的默认配置好了读写函数还有文件系统的配置，只需要挂载就能使用
下面我们来移植FLASH的文件系统的底层驱动
user_diskio.c添加flash的驱动代码

移植过程中遇到的问题，
- SDIO开启dma传输不知道为什么会卡住一回，挂载，和打开文件都正常，但是写入就会卡住，注意不是卡死，然后过一会写入失败，忘记返回的错误代号是什么了，
- 后续添加，突然忘记了
