Hi HarryLe,

I assume you are referning to S32 Design Studio for S32 Platform

NXP GCC for Arm Release based on gcc 6.3/9.2.0/10.2 supports:

#pragma GCC section (text|data|bss|rodata) ".name" pragma.

This pragma allows to redefine standard sections by user defined section

#pragma GCC section (text|data|bss|rodata) "default"

This pragma restores standard section

All the declaraions/code or data/const inbetween the pragmas will be placed to ".name" section.

For more information please see the NXP GCC compiler e.g. releasenotes.pdf (attched) ("C:\NXP\S32DS.3.5\S32DS\build_tools\gcc_v9.2\gcc-9.2-arm32-eabi\releasenotes.pdf")

Hope it helps.

Stan
