STM32F103VET6的板子，使用easyflash V2.12.08版本的时候一保存就卡死了
           easyflash 选择STM32F103的Flash的最后20K，使用擦写平衡，掉电保护模式。

直接出问题的地方是擦flash函数给的地址不是擦写的合法地址：
(..\..\components\easyflash\port\ef_port.c:104) (addr % EF_ERASE_MIN_SIZE == 0) has assert failed at ef_port_erase.

修改代码：
```    if (area0_is_valid) {
        /* current using data section address is area0 current using data section address */
        set_cur_using_data_addr(area0_cur_using_addr);
        /* next save ENV area address is area1 current using address value */
        next_save_area_addr = area1_cur_using_addr;
        /* read all ENV from area0 */
        ef_port_read(area0_cur_using_addr, env_cache, area0_end_addr - area0_cur_using_addr);
    } else if (area1_is_valid) {```
        
        修改为：
```    if (area0_is_valid) {
        /* current using data section address is area0 current using data section address */
        set_cur_using_data_addr(area0_cur_using_addr);
        /* next save ENV area address is area1 current using address value */
        if (area1_is_valid)
            next_save_area_addr = area1_cur_using_addr;
        else
            next_save_area_addr = area1_default_cur_using_addr;```

 *
 * @note all area size must be aligned with EF_ERASE_MIN_SIZE
 * @note EasyFlash will use ram to buffered the ENV.At some time some flash's EF_ERASE_MIN_SIZE is so big,
 *       and you want use ENV size is less than it. So you must defined ENV_USER_SETTING_SIZE for ENV.
 * @note ENV area size has some limitations in different modes.
 *       1.Normal mode: no more limitations
 *       2.Wear leveling mode: system section will used an flash section and the data section will used at least 2 flash sections
 *       3.Power fail safeguard mode: ENV area will has an backup. It is twice as normal mode.
 *       4.wear leveling and power fail safeguard mode: The required capacity will be 2 times the total capacity in wear leveling mode.
 *       For example:
 *       The EF_ERASE_MIN_SIZE is 128K and the ENV_USER_SETTING_SIZE: 2K. The ENV_AREA_SIZE in different mode you can define
 *       1.Normal mode: 1*EF_ERASE_MIN_SIZE
 *       2.Wear leveling mode: 6*EF_ERASE_MIN_SIZE (It has 2 data section to store ENV. So ENV can erase at least 200,000 times)
 *       3.Power fail safeguard mode: 2*EF_ERASE_MIN_SIZE
 *       4.Wear leveling and power fail safeguard mode: 6*EF_ERASE_MIN_SIZE
 * @note the log area size must be more than twice of EF_ERASE_MIN_SIZE
