Problem about spi test on custom k60d100m with MQX 4.1

jerryzhang1

Hi every,
我在开发中碰到个问题。 平台是K60M100M+MQX 4.1。 用MQX 4.1里面的SPI测试程序，结果只有一部分正确。这个硬件平台在MQX 3.8下工作正确。
以下是测试结果。

-------------- SPI driver example --------------

This example application demonstrates usage of SPI driver.
It transfers data to/from external memory over SPI bus.
The default settings in memory.h apply to TWR-MEM flash memory.
Test channel is spi2:
Current baud rate ... 9600000 Hz
Changing the baud rate to 500000 Hz ... OK

Setting transfer mode to SPI_DEVICE_MASTER_MODE ... OK

Simultaneous write and read - memory read from 0x000000f0 (10):
Write: 0x03 0x00 0x00 0xf0 0x00 0x00 0x00 0x00 0x00 0x00
Read : 0xff 0xff 0xff 0xf0 0xf0 0xf0 0x00 0x51 0x52 0x53
Simultaneous read/write (data == 0xf0) ... ERROR


-------------- End of example --------------
对于长字符串测试，第一次16个字符写在了 0x000002f0, 但是从那个地址读的时候，读出来后面写在 0x00000300的数据。

simultaneous write全部都错了。

大家有啥好建议呀?谢谢。
