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:

Enabling Strict ANSI compile?



Currently when you select the dialect there, you can only select ISO standard conformance, which is a lot more strict than the standard gnu settings. You can select gnu-C-90 dialect by letting the dialect unspecified in the “Language Standard” menu, but adding “-std=gnu90” in the “Other dialect flags” box (or any other supported dialect, see the C Compiler documentation in Other Manuals)
