IAR toochain

I configured a demoCAN communication using the IAR toolchain, but the program got stuck in the CAN initialization process. However, with the original GCC toolchain, this phenomenon does not occur. So, is there any configuration needed for this?

NXP:S32DS for platform 3.5

IAR:9.30.1

Please provide the following information:
S32K1 or S32K3?
Are you using an SDK or RTD?
What is the version of SDK or RTD?

Please allow me to use S32SDK_for_S32K1xx_RTM_4.0.1_ReleaseNotes.pdf as an example:
I recommend using the version mentioned in section 6.3 Compiler and IDE versions.
I recommend using the configuration in section 8.1 IAR Compiler/Linker/Assembler Options.

Best Regards,
Robin

Thank you for your reply. The problem was found to be with the aligner. After correcting the issue, the function has been successfully implemented.
