1、测试环境
硬件：I.MX 1052
rtthread版本：4.0.3
IDE版本：keil 5.27
Flash芯片：W25Q128
SPI:4线spi，非qspi

2、初始化打印如下
```

3、msh 指令测试如下，测试正常
```
msh >sf read 0 32
Read the sf_cmd flash 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] FF FF FF FF FF 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 ................

msh >sf write 0 0 1 2 3 4 5 6 7
Too many args ! We only Use:
sf write 0 0 1 2 3 4 5 6 
Write the sf_cmd flash data success. Start from 0x00000000, size is 7.
Write data: 0 1 2 3 4 5 6 .
msh >sf write 7 7 8 9 10 11 12 13 14
Too many args ! We only Use:
sf write 7 7 8 9 10 11 12 13 
Write the sf_cmd flash data success. Start from 0x00000007, size is 7.
Write data: 7 8 9 10 11 12 13 .
msh >sf read 0 32
Read the sf_cmd flash 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] 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D FF FF ................
[00000010] FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF ................

```

4、sf bench 测试，读失败
```
msh >sf bench yes
Erasing the sf_cmd 16777216 bytes data, waiting...
Erase benchmark success, total time: 35.413S.
Writing the sf_cmd 16777216 bytes data, waiting...
Write benchmark success, total time: 131.036S.
Reading the sf_cmd 16777216 bytes data, waiting...
Data check ERROR! Please check you flash by other command.
Read sf_cmd failed, already rd for 0 bytes, read 256 each time
Read benchmark has an error. Error code: 3.
This flash operate has an error. Error code: 3.
```
比较奇怪的一个点是，bench测试失败，在通过sf read/write 测试，读写不正常。
但是在程序启动后测试都正常， easyflash也能正常启动，但是bench测试通不过
```
