Board: EFR32MG12 (BRD4161A Rev A02)
Toolchain: IAR ARM v8.30
How to deal with this information?
I tried it and changed the IAR version to v7.80, but it still happens.
My Micrium OS is the same version.
I tracked the symbols that showed the error and found that they ended up pointing to the iar.h file. This may be a compiler feature of the CDT index that is not compatible with IAR.
You can try to rebuild this example. After the compilation is complete, you may find some warnings in the Problems tab, then you click these warnings with your mouse, and then the problems I have described will appear.
You can try to click on these warnings one by one, and then you will find that it will show me the wrong symbolic symbols.
I think this is a CDT issue, because I used the IAR IDE to compile the project and found that there are no such errors.
