1. 启用外部norflash

开启后编译下载，list_device 看到norflash说明成功。

保存编译后会出现很多问题。studio老问题了，ports文件夹不见了，把ports改成port

保留ef_fal_port.c

编译下载，发现没有初始化

在main函数里添加easyflash_init()。main.c可以添加#include "easyflash.h"，避免有警告，不加也可以。

编译下载后会报错。

`el_fal_port.c` 修改`FAL_EF_PART_NAME`的值

```c
//#define FAL_EF_PART_NAME               "ef"
#define FAL_EF_PART_NAME               "easyflash"
```

编译下载，恭喜你，启动成功

添加启动次数函数

```c
static void BootTimes(void) {
    uint32_t i_boot_times = NULL;
    char *c_old_boot_times, c_new_boot_times[11] = {0};

/* get the boot count number from Env */
    c_old_boot_times = ef_get_env("boot_times");
    assert_param(c_old_boot_times);
    i_boot_times = atol(c_old_boot_times);
    /* boot count +1 */
    i_boot_times ++;
    rt_kprintf("The system now boot %d times\n\r", i_boot_times);
    /* interger to string */
    rt_sprintf(c_new_boot_times,"%ld", i_boot_times);
    /* set and store the boot count number to Env */
    ef_set_env("boot_times", c_new_boot_times);
    ef_save_env();
}
```
`ef_fal_port.c` 可以设置默认的环境变量
