修改配置文件fal_cfg.h

#endif /* FAL_PART_HAS_TABLE_CFG */#endif /* _FAL_CFG_H_ */复制demo中文件修改内部flash驱动接口
更名为：fal_flash_gd32f2_port.c(这个操作依据自己芯片平台非必须)
主要完善以下接口：
- 内部FLASH的读取，写入，擦除操作
- 内部FLASH的属性配置
GD32的FLASH操作接口已改为HAL方式，HAL的移植方式参考我的博客https://blog.csdn.net/weixin_42892101/article/details/106135522

};外部SPI Flash的接口配置
由于操作flash的接口是由sfud万能驱动接口做的，所以参考sfud的移植，当然不移植就需要自己实现外部SPI Flash的读取/写入/擦除驱动。
fal_flash_sfud_port.c修改如下：
#include <fal.h>
#include <sfud.h>#define FAL_USING_SFUD_PORT
#ifdef FAL_USING_SFUD_PORT
#ifdef RT_USING_SFUD
#include <spi_flash_sfud.h>
#endif#ifndef FAL_USING_NOR_FLASH_DEV_NAME
#define FAL_USING_NOR_FLASH_DEV_NAME "norflash0"
#endifstatic int init(void);
static int read(long offset, uint8_t *buf, size_t size);
static int write(long offset, const uint8_t *buf, size_t size);
static int erase(long offset, size_t size);static sfud_flash_t sfud_dev = NULL;
struct fal_flash_dev nor_flash0 =
{.name = FAL_USING_NOR_FLASH_DEV_NAME,.addr = 0,.len = 8 * 1024 * 1024,.blk_size = 4096,.ops = {init, read, write, erase},.write_gran = 1
};static int init(void)
{#ifdef RT_USING_SFUD/* RT-Thread RTOS platform */sfud_dev = rt_sfud_flash_find_by_dev_name(FAL_USING_NOR_FLASH_DEV_NAME);
#else/* bare metal platform */sfud_dev = sfud_get_device(SFUD_GD25Q16B_DEVICE_INDEX);
#endifif (NULL == sfud_dev){return -1;}/* update the flash chip information */nor_flash0.blk_size = sfud_dev->chip.erase_gran;nor_flash0.len = sfud_dev->chip.capacity;return 0;
}static int read(long offset, uint8_t *buf, size_t size)
{assert(sfud_dev);assert(sfud_dev->init_ok);sfud_read(sfud_dev, nor_flash0.addr + offset, size, buf);return size;
}static int write(long offset, const uint8_t *buf, size_t size)
{assert(sfud_dev);assert(sfud_dev->init_ok);if (sfud_write(sfud_dev, nor_flash0.addr + offset, size, buf) != SFUD_SUCCESS){return -1;}return size;
}static int erase(long offset, size_t size)
{assert(sfud_dev);assert(sfud_dev->init_ok);if (sfud_erase(sfud_dev, nor_flash0.addr + offset, size) != SFUD_SUCCESS){return -1;}return size;
}
#endif /* FAL_USING_SFUD_PORT */测试代码
建议调试打开打印功能
在文件fal_def.h中，#define FAL_DEBUG 1
必须的初始化
#include "fal.h"
int main(void)
{fal_init();
}
读写擦除
接口都在fal.h中
懒得写了。。。。。。
Easyflash的移植
目前最新版本的Easyflash V5.X或者最新更名的FlashDB 底层调用接口都是FAL，所以实现了FAL移植，Easyflash和FlashDB都无需较大更改，直接加入源码到工程目录即可使用。
需要注意的是：easyflash首先执行初始化sfud，之后是fal初始化，否则flash容量大小会被篡改为0！
当使用操作系统时，注意线程分配的堆栈大小，应>512Byte否则易出现Hardfault错误，坑已踩过！
修改fdb的cfg文件
主要增加宏定义：#define FDB_USING_KVDB与设置FDB_WRITE_GRAN大小
