MCAL接口写完FLS后，偶发性出现一直不空闲问题
-
houjun_xiao 经过我们的测试，发现有部分MCU在执行完Fls_Erase、Fls_Write、Fls_Read后，就是特别容易出现Fls_GetStatus返回一直为BUSY，实际上，通过读取memory看到，擦写操作是已经完成的了。即使增加很多的延时等待，重复读Fls_GetStatus也一直没法解决。现在我们的操作是，增加一个Fls_Cancel操作，异常情况暂时是没再复现，但是不知道是不是已经根本性解决问题。

你们出现问题的频次大概是多久一次呢，我用你们测试的代码和配置测了一下，没有复现现象。我测试的时候删除了一部分无效调用Fls_MainFunction的代码，你可以对比一下。测试的MCU PLL为200MHz. 另外需要注意，测试写入和读取的时候，长度都是1M, 你需要确认一下这两个测试里面用到的指针的有效范围。/* USER CODE BEGIN Header */ /* you can remove the copyright */ /* * Copyright 2020-2023 Yuntu Microelectronics co.,ltd * All rights reserved. * * YUNTU Confidential.

houjun_xiao 部分板子的复现概率还是挺高的，刚试了一下你这份改动的代码，也会出现错误：
查看了一下memory，写操作返回了成功，但是实际上没有写入数据 -
houjun_xiao 这个理解的。我们设计代码时，参考了Fls_Demo以及FLS-FEE MCAL应用介绍_20241127.pptx的指导。发现写完之后读不出来或者就没写进去，但是底层写/读接口返回值都是正常，Fls_GetStatus接口返回为Busy，才加上了先Fls_Cancel，再进行重新读写的方案
-
Fee的操作跟Fls是一样的，他的操作函数都是异步函数，需要调用Fee_MainFunction来进行调度和状态管理，同时由于Fee需要调用Fls的操作才能实现数据存储与读取，因此调用Fee_MainFunction的同时，也需要调用Fls_MainFunction
