FYI:

If you use IDE project in S32DS v1.2 - there is an automatic way to fix the linker differences.

You basically right click on a linker script warning in Problems View and select  "Quick Fix" option.

This will add the additional linker sections that are required by the updated GCC compiler/linker:

This feature is documented in FAQ manual:

<S32DS_Power_v1.2>\S32DS\help\pdf\s32ds.pwr.win.faq.pdf

section "3.3 Open a project made in previous version of S32DS Power"

Stanislav

Hi Erwan, 

you need to update linker files for 4.9.4 version. In attachment are default linker files for MPC56xx. If you have no special configuration in you linker files - you can use them in your project otherwise you need to update your existing linker files.
