flexspi flash读写失败

[1150666288]

硬件：mcu：rt1010       flash：w25q32fvzpig

          我的板子外接了一个nor flash w25q32 ，但是我通过flexspi操作flash读写，运行FLEXSPI_SoftwareReset时，会进入硬件错误。可能的原因是什么？

          我的程序在rt1010中已经可以正常运行。附件是用配置工具生成的.mex文件。

参考例程：SDK_2.6.0_EVK-MIMXRT10\boards\evkmimxrt1010\driver_examples\flexspi

Hi 志成 项 ,

非常感谢使用NXP产品，很高兴为你提供技术支持！
查看过mt.mex 文件发现，连接w25q32的引脚与MIMXRT1010开发板是一样的，可以排除硬件方面的问题。
而根据你的描述，‘’运行FLEXSPI_SoftwareReset时，会进入硬件错误。‘’，我想知道的是在运行例程哪一个flash操作函数时出错呢？
同时，我建议你使用逻辑分析仪抓取信号分析一下，这样会给我们很多的信息来分析问题所在。

Have a great day,

hi zhou：

         我任然没有解决这个问题。同时我发现在我的板子上直接运行SDK_2.6.0_EVK-MIMXRT10\boards\evkmimxrt1010\driver_examples\flexspi此工程，也会有类似的问题。是哪里出了问题？

        具体的函数和调试信息可以见下图。

Hi 志成 项 ,

感谢回复，我并没有你所说的具体函数和调试信息图。

        在单步调试时，运行到flexspi-clock-init,之后立即会退出调试。以上是出问题的具体信息。有任何需要，可以随时联系我。

Hi 志成 项 ,

这个测试是在你自己的板子上运行的，QSPI Flash是w25q32吗？

根据截图，代码其实已经可以在QSPI运行了，只是运行flexspi_nor_polling_transfer工程代码时出错了，你有尝试将工程代码运行在RAM中执行吗，如果有的话，也会碰到类似错误吗？

   我尝试将相关函数放在ram中执行，但也会有同样的问题。

Hi 志成 项 ,

感谢回复。

1) 这个测试是在你自己的板子上运行的，QSPI Flash是w25q32吗？

2) 请问上面的函数放在RAM中执行，只是将上述函数进行转移呢，还是整个工程都是在RAM中呢？

hi！

     1.是的，在我自己的板子上运行的，qspi flash是w25q32.

     2.只是将上面的函数放在ram中执行。

Hi ,

从现象来判断，现象可能与硬件连接有关，但是从你的回复来看，代码可以在w25q32执行，又与前面的结论矛盾了。

你有在尝试过将整个代码运行在RAM中去读写w25q32吗？

hi

      我在程序中去除flexspi_nor_flash_init（），并关闭所有的中断。此时flash的读写都正常。我想知道，如果我要操作flash，关闭中断是必须的吗?

这对我的程序逻辑有较大的影响。

Hi 志成 项,

感谢回复。

1）如果我要操作flash，关闭中断是必须的吗?

-- 不是必须，但是建议关闭全局中断，以排除干扰。
