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

Syntax error about "__weak","__attribute__((weak))"

not me, stm32cubemx do that by default,,

I just want to make my IDE support C99


There is two possibilities here:

  1. Either you just want to be able to use C99 features; in this case you don’t have to do anything, as the default selection for GCC is -std=gnu11, that is C11 plus GNU extensions, so it supports C99.
  2. Either you want to be sure you are fully C99 conformant to standard iso9899:1999, with no GNU extensions, then you should effectively select -std=c99, but you should also add -Wpedantic, as otherwise it will still accept some GNU extensions, as well as some c11 features...

BTW, the default for C is -std=gnu11 and for C++ it’s -std=gnu98.

Hope this helps,
