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 (registration required) various documents highlighting:

Cannot debug projects after SW4STM32 upgrade to Version 2.3



The reason it does not work is you do not create a SW4STM32 project: by creating a “Makefile Project with Existing Code”, you create a plain Eclipse project. This is meant for cases where you have created your project totally manually and only want Eclipse to edit the code and start the build.

The proper way to create a project is creating a “C Project” or “C++ Project” instead of a “Makefile Project with Existing Code”; then on the next screen, you must choose the project kind (usually Executable or Static Library, if you want SW4STM32 to generate your Makefiles automatically) and the AC6 STM32 MCU GCC toolchain.

You should not choose “GNU Autotools” nor “Shared Library” project kinds as these are not supported if you don’t have an OS like Linux or Windows; you may choose “Makefile Project” here but you will have to create and update your Makefile manually, so this is probably not what you want.
