移植完了FAL，用命令行，把easyflash的分区读写擦都试过了，没有问题。fal bench也是正常的。
增加上easyflash后，并增加初始化代码，显示env分配空间不足。

msh >user_easy_flash
[Flash] (../packages/EasyFlash-v4.1.0/src/ef_env.c:1818) ENV start address is 0x00000000, size is 8192 bytes.
[Flash] Warning: Sector header check failed. Format this sector (0x00000000).
[D/fal_flash_port] erase done: addr (0x08100000), size 4096

然后我命令行挂载easyflash的分区，读一下flash，全是ff.
自己用命令行写，再读出来是没问题的。

```
msh >fal write 0 1 2 3 4 5
Write data success. Start from 0x00000000, size is 5.
Write data: 1 2 3 4 5 .
msh >fal read 32
Usage: fal read addr size               - read 'size' bytes starting at 'addr'.
msh >fal read 0 32
Read data success. Start from 0x00000000, size is 32. The data is:
Offset (h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
[00000000] 01 02 03 04 05 FF FF FF FF FF FF FF FF FF FF FF ................
[00000010] FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF ................
```
