FOC SDK 4.2使用Eclipse AC6清除拇指模式遇到错误

嗨，

我最近遇到了FOC SDK 4.2基本电机控制项目的问题。
在为Eclipse AC6组装项目（来自Web版本的API源+ EWARM库）之后，我在库中执行初始化函数时遇到了使用错误。
我进一步研究了这一点，发现函数''PWMC_Init''的一个分支（BLX R1）到''R3_4_F30X_Init''清除了EPSR的T-Bit。分支前R1的内容为0x8001f88。所以行为很明确：地址是偶数而不是奇怪，因为它应该保留拇指模式。因此，CPU进入ARM模式并在下一条指令上失败，因为它只支持拇指模式。 （这是STM32F303VCT6）

为了解决这个问题，我刚刚申请了FOC SDK源代码的许可协议。希望我很快就能收到表格。

但是，我也想在这里讨论这个问题。我错了，IAR编译器（EWARM库）的行为应该与GCC相同，并在编译时向分支目标地址添加0x1吗？如果这是真的，那么SDK版本4.2的STM32F303_single_drive库可能是用错误的选项构建的吗？

最好的祝福，
马丁克雷尔曼

编辑：或者我的代码对齐错误了吗？这是偶数地址，正如我所期望的那样。

Hi,


i recently ran into a problem with a FOC SDK 4.2 base motor control project.
After assembling a project for Eclipse AC6 (API sources + EWARM library from web edition) I got usage faults during the execution of a initialization function in the library.
I investigated this further and found out that a branch (BLX R1) to ''R3_4_F30X_Init'' from the function ''PWMC_Init'' cleared the T-Bit of the EPSR. The content of R1 was 0x8001f88 before the branch. So the behaviour is clear: The address is even and not odd as it should for preserving thumb mode. Thus, the CPU enters ARM mode and fails on the next instruction since it only supports thumb mode. (It is a STM32F303VCT6)

To resolve the problem for me I just requested a license agreement for the source code of the FOC SDK. Hopefully I will receive the forms soon.

But, I wanted to discuss this here as well. Am I wrong that the IAR compiler (EWARM library) should behave the same way as GCC and add a 0x1 to the branch target address at compile time? If this is true, then maybe the STM32F303_single_drive library of SDK version 4.2 was build with wrong options?

Best regards,
Martin Krellmann.

Edit: Or did I make a mistake with my code alignment? Which is on even addresses as I would expect it to be.
