flashDB 初始化，提示读取扇区信息失败的断言？

1.KV数据库存放在外部SPIflash中。
rt-thread 系统版本V4.1.0  ;
flashDB 版本V1.1.2;
使用rt-thread studio ;

2.flash做了分区。分区表如下：

```c
#define FAL_PART_TABLE                                                               \
{                                                                                    \
    {FAL_PART_MAGIC_WORD,        "app",     "onchip_flash",             0,   512*1024, 0},   \
    {FAL_PART_MAGIC_WORD,   "download", NOR_FLASH_DEV_NAME,             0,   256*4096, 0},   \
    {FAL_PART_MAGIC_WORD,  "kvdbflash", NOR_FLASH_DEV_NAME,      256*4096,   256*4096, 0},   \
    {FAL_PART_MAGIC_WORD,  "tsdbflash", NOR_FLASH_DEV_NAME,      512*4096,  1024*4096, 0},   \
    {FAL_PART_MAGIC_WORD,  "ulogflash", NOR_FLASH_DEV_NAME,     1536*4096,   256*4096, 0},   \
    {FAL_PART_MAGIC_WORD,  "fileflash", NOR_FLASH_DEV_NAME,     1792*4096,  2304*4096, 0},   \
}
```

3.使用官方例程的初始化，初始化kvdb没有问题，但是初始化tsdb的时候就会出现断言；调试信息如下：

```
[32;22m[I/FAL] RT-Thread Flash Abstraction Layer initialize success.[0m
[32;22m[I/FAL] The FAL block device (fileflash) created successfully[0m
onchip elm filesystem mount to '/' success
[FlashDB][kv][env] (../packages/FlashDB-v1.1.2/src/fdb_kvdb.c:1638) KVDB size is 524288 bytes.
[FlashDB] FlashDB V1.1.2 is initialize success.
[FlashDB] You can get the latest version on https://github.com/armink/FlashDB .

><=====================================================><
get the 'boot_count' value is 7
set the 'boot_count' value to 8

[FlashDB][tsl][tsflash] (../packages/FlashDB-v1.1.2/src/fdb_tsdb.c:192) (0) has assert failed at read_sector_info.
```

在fdb_tsdb.c的第192行：

```
//TODO There is no valid end node info on this sector, need impl fast query this sector by fdb_tsl_iter_by_time
        FDB_ASSERT(0);
```

注释说明，扇区上没有有效的结束节点信息，请使用fdb_tsl_iter_by_time函数查询。
这是什么原因呢？？？

初始化函数内容如下：
```c
    {
        fdb_err_t result1;
        fdb_tsdb_control(&tsdb_flash, FDB_TSDB_CTRL_SET_LOCK, lock);
        fdb_tsdb_control(&tsdb_flash, FDB_TSDB_CTRL_SET_UNLOCK, unlock);
        result1 = fdb_tsdb_init(&tsdb_flash,"tsenv","tsdbflash",get_time,128,NULL);
        fdb_tsdb_control(&tsdb_flash, FDB_TSDB_CTRL_GET_LAST_TIME, &counts);
        if (result1 != FDB_NO_ERR) {
            return -1;
        }
        tsdb_sample(&tsdb_flash);
    }
```

以上问题不知有没有人遇到过？？这个要怎么解决呢？
