SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download two short videos (registration required) highlighting:

Conditional Linker script


as far as I know gcc linker cannot read defines made in header, but you can add symbol definition to you linker using defsym

example :

in you project properties > C/C++ Build > Settings > Tools Sttings (tab) > MCU GCC Linker > Miscellaneous > Linker flags add


and in my linker I add this

stack_size = DEFINED(stack_size) ? stack_size : 0x400 ;
