fal分区没有问题，使用到测试过正常，按照说明设置，使用的是片内flash,代码如下：
拷贝的是ef_fal_port.c的代码测试，而且第一个变量都识别不出来，

修改部分如下，
```c
/* EasyFlash partition name on FAL partition table*/
#define FAL_EF_PART_NAME               "ef"

/* default ENV set for user */
static const ef_env default_env_set[] = {
        {"boot_times1", "0"},
        {"boot_times2", "1"},
};
```
然后在主函数去调用初始化函数 easyflash_init();
为什么会出现以下问题？哪里还要配置吗？
```

fal_cfg.h fal分区如下：
```c

#define FAL_FLASH_DEV_TABLE                                          \

}
#endif /* FAL_PART_HAS_TABLE_CFG */
```

@yc961213911  感谢， 
1、EasyFlash V4.1.0版本的在seting里面的配置基本都是默认的，见图

2、fal_cfg分区很奇怪？app是说分区的起始位置还是说程序，分区我只是随便分了测试的，
芯片是用f4的，分区是分了三个分区，按16k,64k,128k的，进行分区的 fal_cfg的代码基本如下，：

```
#ifndef _FAL_CFG_H_
#define _FAL_CFG_H_

#include <rtconfig.h>
#include <board.h>

#define FLASH_SIZE_GRANULARITY_16K        (4 * 16 * 1024)
#define FLASH_SIZE_GRANULARITY_64K        (64 * 1024)
#define FLASH_SIZE_GRANULARITY_128K        (3 * 128 * 1024)
#define STM32_FLASH_START_ADRESS_16K    ROM_START
#define STM32_FLASH_START_ADRESS_64K    (STM32_FLASH_START_ADRESS_16K + FLASH_SIZE_GRANULARITY_16K)
#define STM32_FLASH_START_ADRESS_128K    (STM32_FLASH_START_ADRESS_64K + FLASH_SIZE_GRANULARITY_64K)

/* ===================== Flash device Configuration ========================= */
extern const struct fal_flash_dev stm32_onchip_flash_16k;
extern const struct fal_flash_dev stm32_onchip_flash_64k;
extern const struct fal_flash_dev stm32_onchip_flash_128k;
/* flash device table */
#define FAL_FLASH_DEV_TABLE                                          \
{                                                                    \
    &stm32_onchip_flash_16k,                                         \
    &stm32_onchip_flash_64k,                                         \
    &stm32_onchip_flash_128k,                                         \
}
/* ====================== Partition Configuration ========================== */
#ifdef FAL_PART_HAS_TABLE_CFG
/* partition table */
#define FAL_PART_TABLE                                                               \
{                                                                                    \
    {FAL_PART_MAGIC_WORD,        "ab",     "onchip_flash_16k",         0,   FLASH_SIZE_GRANULARITY_16K, 0}, \
    {FAL_PART_MAGIC_WORD,        "bc",     "onchip_flash_64k",         0,   FLASH_SIZE_GRANULARITY_64K, 0}, \
    {FAL_PART_MAGIC_WORD,        "ef",     "onchip_flash_128k",         0,   STM32_FLASH_START_ADRESS_128K, 0}, \
}
#endif /* FAL_PART_HAS_TABLE_CFG */
```

程序的起始是默认位置没有修改。
