S32K312 IAR EW Integrate Problem

Hello NXP Community,

I encountered the following issues when integrating the S32K312 MCAL into IAR EW:

After enabling the MCAL_ENABLE_USER_MODE_SUPPORT predefined macro, the following error occurred: the definitions of the functions "startup_getControlRegisterValue" and "startup_getAipsRegisterValue" could not be found. According to the IM manual, this macro needs to be enabled. What are the impacts if this macro is not enabled?
The following compilation error occurred: Error[Lp004]: actual size (0x448) exceeds maximum size (0x410) for block "interrupt_vector_init". How can this be resolved?

RTD: SW32K3_S32M27x_RTD_R21-11_6.0.0

EB: 29.0

MCU: S32K312

IDE: IAR EW 9.40.1

We don't support IAR EW 9.40.1, please contact IAR Systems https://www.iar.com/support

But I can reproduce the same error In S32DS if the macro is defined in the C compiler preprocessor only.

You need to define the macro in both the C compiler preprocesor and the Assembler preprocessor.
