STM32F4使用MDK5更新最新版的ARM::CMSIS编译遇到问题 [复制链接]

新建一个工程，在Options for Target中的C/C++的Define中加入ARM_MATH_CM4 __FPU_PRESENT=1启用FPU
然后使用arm_math.h库中的任何一个有关浮点运算的方法都会报下边的错误

1. arm_max_f32.o attributes are not compatible with the provided cpu and fpu attributes .
   
2. Object arm_max_f32.o contains Build Attributes that are incompatible with the CPU attributes.

我使用了一条求浮点数最大值的函数然后就报了下边的错误

1. arm_max_f32(buf, 50, &maxValue, &maxIndex);

复制代码

最后没有办法了，在Select Software Packs for Target中把ARM::CMSIS的版本从4.5.0改成4.4.0后解决，不知道为什么会出这个问题。

虾哥，可以对比下4.4和4.5的arm_math.h的这个文件有啥不同，看看能不能看出些端倪。
我是5.13的版本，现在是4.4和4.3的CMSIS的版本。我用文本比较器，对比了一下，arm_max_f32这个函数好像没什么区别呢。您再看下参数啦。

谢谢
我今天又查了一下资料，看到有一个贴子，确定是我的MDK版本5.14不支持CMSIS 4.5.0

The pack ARM:CMSIS version 4.5.0 is not compatible with the version 5.16a of uVision. You must still continue to use version ARM:CMSIS v4.4.0 till version 5.17 of uVision.

哦哦，明白了。我说呢。这个您在选择device的时候就可以看得出的。如果没有您的型号，就需要升级库或者软件升级了。
