S32 Design Studio for ARM S32K144 BLDC

[MrShen]

I am using S32 Design Studio for ARM Version 2.2, with SDK V2.2. Importing the BLDC example from MC_DevKits, the compilation fails.

arm-none-eabi-gcc.exe: error: unrecognized argument in option '-march=armv7e-m+fp'

Is it a GCC problem? How should I configure it?

Hi @MrShen 

I was able to replicate the issue you described.

AMMCLib version 1.1.44 uses GCC version 10.2, which causes compatibility issues with the toolchain version used to develop the MCSPTE1AK144 application software.

As a workaround, you may downgrade AMMCLib to any version within the range 1.1.33 to 1.1.43, as AMMCLib is backward compatible.

Previous versions can be downloaded from Automotive Math and Motor Control Library Set for S32K14x.

Once the download and installation are complete, please follow these steps:

• Remove the AMMCLib 1.1.44 installation from disk.
• Run the MCSPTE1AK144 installer again.
• Delete the examples from your workspace and re-import them.
