External SPI Flash issue

Hi there,

I have made a custom board with the Winbond W25X10 (2-MBit) SPI flash module (USON8 footprint). My SPI pinout is the same as the Basic Dev kit (SCLK = P0.0, CS = P0.3, MISO = P0.5, MOSI = P0.6). When I read the flash module with the SPI _flash example project (provided within the SDK5.0.2.1 folder), I can read the flash unique ID and manufacturer ID, and the SPI flash module pass the test for unprotected and protected w/r. However, when I try to read it with the smart snippet v3.9, all I get is rubbish (I have the correct SPI setting) and I can't erase the sector (err: Verification failed at address 0x00). Any idea what could be causing this problem? Thank you!

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

Reading [0x00000] = 0xFF and [0x20000] = 0xFF

(must be [0x00000] = 0xFF and [0x20000] = 0xFF, as the memory has been cleared)

3) Writing [0x00000]<- 0xE0 and [0x20000]<- 0x0E to the unprotected memory

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

Reading [0x00000] = 0xE0 and [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) Writing [0x00000]<- 0x70 and [0x20000]<- 0x07 to the 'upper-half only protected' memory

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

(必须是[0 x00000] = 0 x60和[0 x20000] =0x0A, as only the lower half is writable)

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

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