外部SPI Flash问题

你好呀，

我使用Winbond W25X10（2-Mbit）SPI闪存模块（USON8占地面积）进行了定制板。我的SPI引脚引脚与基本开发套件（SCLK = P0.0，CS = P0.3，MISO = P0.5，MOSI = P0.6）相同。当我用SPI _FLASH示例项目读取Flash模块（在SDK5.0.2.1文件夹中提供）时，我可以读取闪光灯唯一ID和制造商ID，并且SPI Flash模块通过测试，以便无保护和受保护的W / R。但是，当我尝试用智能赛段v3.9阅读它时，我得到的只是垃圾（我有正确的spi设置），我无法删除扇区（err：验证在地址0x00时失败）。任何想法可能导致这个问题是什么？谢谢！

The test result from the SPI_flash project.

W25X20 SPI memory protection features demo.

1) Unprotecting the whole memory array and doing a full erase

2) Retrieving the two bytes at addresses 0x00000 and 0x20000

读取[0x00000] = 0xFF和[0x20000] = 0xFF

（必须是[0x00000] = 0xFF和[0x20000] = 0xFF，因为内存已被清除）

3）将[0x00000] < - 0xe0和[0x20000] < - 0x0E写入未受保护的内存

Reading [0x00000] = 0xE0 and [0x20000] = 0x0E

(must be [0x00000] = 0xE0 and [0x20000] = 0x0E)

4) Enabling memory protection for the whole memory array.

5) Writing [0x00000]<- 0xD0 and [0x20000]<- 0x0D to the fully protected memory

Reading [0x00000] = 0xE0 and [0x10000] = 0x0E

(must be [0x00000] = 0xE0 and [0x20000] = 0x0E), the old values)

6) Enabling memory protection ONLY for the lower half (0..0x1FFFF) of the memory array

7) Writing [0x00000]<- 0xB0 and [0x20000]<- 0x0B to the 'lower-half only protected' memory

读取[0x00000] = 0xe0和[0x10000] = 0x0a

(must be [0x00000] = 0xE0 and [0x20000] = 0x0A (= 0x0E AND 0x0B), as only the upper half is writable)

8) Enabling memory protection ONLY for the upper half (0x20000..0x3FFFF) of the memory array

9）写入[0x00000] < - 0x70和[0x20000] < - 0x07至“仅限仅受保护”的内存

Reading [0x00000] = 0x60 and [0x20000] = 0x0A

（必须是[0x00000] = 0x60和[0x20000] = 0x0a，只有下半部分是可写的）

IMPORTANT NOTE: The API supports the protection also in quarters of the memory array for this device.
