【RT-Thread Studio】nor flash配置Fal分区

添加 FAL软件包

配置SFUD驱动程序，使用FAL的设备为W25Q128

将fal_cfg.h和fal_flash_sfud_port.c提取出来，放到自己创建的fal_porting目录。

修改
fal_flash_sfud_port.c

c 复制代码

struct fal_flash_dev nor_flash0 =
{
    .name       = FAL_USING_NOR_FLASH_DEV_NAME,
    .addr       = 0,
    .len        = 16 * 1024 * 1024,
    .blk_size   = 4096,
    .ops        = {init, read, write, erase},
    .write_gran = 1
};

fal_cfg.h

c 复制代码

#define NOR_FLASH_DEV_NAME             FAL_USING_NOR_FLASH_DEV_NAME

/* ===================== Flash device Configuration ========================= */

测试应用

c 复制代码

#include <app_fs/w25qxx.h>
#include <fal.h>

static void app_fs_init(void)
{
    dev_spi_flash_init();
    fal_init();
}

static int component_app_fs_init(void)
{
    app_fs_init();
    return RT_EOK;
}
