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:

System Workbench for STM32


C99

When selecting the dialect of C as C99 (to have more recent C features) the default project (based on STM32F407) is not compiling, the first error is on this line of syscalls.c:

register char * stack_ptr asm(“sp”);

I guess the same thing will happen when selecting C11.

Also, not connected to C dialect (I’m writing here to not create another thread) there are many warnings that “STM32F40_41xxx” is redefined.

That is perfectly normal behavior: you ask to use C99 strict compatibility, without Gnu extension, that is without the asm mechanisms...

If you want to use C99 or C11 eatures, you should select gnu99 or gnu11; see C standards supported by GCCQuestion

There were no gnu99 or gnu11 in the MCU GCC Compiler -> Dialect -> Language Standard combo-box, so I had to write -std=gnu99 in the Other dialect flags field which did the job.

Thanks for clarification.
