**1.背景：**
主控芯片：LPC54606
Flash芯片：W25Q256
SPI总线：SPIFI

**2.初始化打印信息如下:**

**3.sf 命令测试结果如下：**
msh />sf bench yes
Erasing the sf_cmd 33554432 bytes data, waiting...
Erase benchmark success, total time: 45.389S.
Writing the sf_cmd 33554432 bytes data, waiting...
Write benchmark success, total time: 131.072S.
Reading the sf_cmd 33554432 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.

msh />sf write 0 1 2 3 4 5
Write the sf_cmd flash data success. Start from 0x00000000, size is 5.
Write data: 1 2 3 4 5 .
msh />sf read 0 16
Read the sf_cmd flash data success. Start from 0x00000000, size is 16. The data is:
Offset (h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
[00000000] 00 00 00 01 00 01 04 05 55 55 55 55 55 55 55 55 ........UUUUUUUU

4.问题
从sf测试的情况来看，对flash的操作还是有问题的。
1)写入读入数据不一致；
2)sf bench 最后的read出错了；
还想请问一下，各位有没有遇到类似的问题，如何解决的？
