是否可以将STM32 FOC SDK与IAR EWARM或Keil MDK-ARM之外的编译器一起使用

我已经尝试过，现在设法用gcc编译FOC代码。
 
 
了解FOC代码，同时将其移植到不受支持的编译器是很棘手的。最后，在我能够使用gcc之前，我必须“（几乎）与KEIL一起工作”。
 
一些FOC代码是“仅二进制”。这是作为其中一个受支持的编译器的库提供的。事实证明，gcc支持IAR库格式。
 
但是，IAR通过消除从未调用过的函数来优化代码。此功能也存在于gnu工具链中，但实现方式不同，因此它不适用于提供的IAR库。 。因此，您需要重新编译库（但是您没有获得源代码），或者是因为它将大约20k的死代码编译到二进制文件中。
 
此外，gnu链接器还有一个尚未在主流分布式二进制文件中修复的错误：PC对拇指函数的相对引用未正确链接。

也就是说，我已经成功移植到海湾合作委员会....所以这是可能的。但没有ST的支持，因为他们说“不支持”......



以下为原文





I've tried and by now managed to compile the FOC code with gcc.


Getting to know the FOC code while at the same time porting it to an unsupported compiler is tricky. In the end I had to ''get it (almost) working with KEIL'' before I was able to get it to work with gcc.  

Some of the FOC code is ''binary only''. This is provided as a library for one of the supported compilers. It turns out that gcc supports the IAR library format.  

However, IAR apparenlty optimizes the code by eliminating functions that are never called. This functionality also exists in the gnu toolchain, but is implemented differently so it doesn't work with the supplied IAR library. . Therefore you'd need to recompile the library (but you don't get the source), or live with the fact that it compiles some 20k of dead code into your binary.  

Also the gnu linker has a bug that isn't yet fixed in the mainstream distributed binaries: The PC relative references to thumb functions are not linked correctly.

That said, I've manged to port to GCC.... So it is possible. But there is no support from ST, as they say ''not supported''....

你好Wolff.roger，
 
 
 你能否就如何使用gcc进行编译提供一些指导？
 
 目前我被困在链接预编译的目标文件。即链接STO_SpeednPosFdbkClass.o等，使程序在MCBoot函数上抛出硬故障。



以下为原文





Hello Wolff.roger,


Could you give some pointers on how you were able to compile with gcc?

Currently I'm stuck linking pre-compiled object files. i.e. linking STO_SpeednPosFdbkClass.o and such, makes the program throw a Hard Fault on MCBoot function.

您需要先修复链接器错误。它通过指针调用非拇指函数，然后CPU抛出异常，因为它不支持非拇指。



以下为原文







You need to fix the linker bug first. It is calling a non-thumb function through a pointer, and the CPU then throws an exception because it doesn't support non-thumb.
