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.

How do I compile a .h file?


Hi again,

BTW the fact that Eclipse shows the macro expanding as 0 (which is seen also as the code itself is grayed out) may be an artifact due to indexing problems. To check you may rebuild th eindex, or go in th efile where the #if shows the value as 0 and

  1. add a syntax error in the conditionnaly compiled zone to check if it is compiled or not
  2. search which “main.h” file Eclipse think you are including by double clicking on “main.h” in the file outline (right column in your workspace): this will open the main.h file and you can check if your macro is defined as 1 or 0 (you can get the full pathname by hovering on the editor tab title).

Hope this helps
