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 two short videos (registration required) highlighting:

System Workbench for STM32


System Workbench for STM32 program license

Hello, I am Ryan.

I have one question.

Is the SW4STM32 program available for free in our company?

Plese, answer me.

Hi Ryan,

Yes, System Workbench for STM32, as avilable on this site, is totally free for both personal and commercial use, to develop code running on STM32 processors.

Hello Bernard,

what about the code the System Workbench for STM32 produces? Can it also be used for commercial products (sell device, closed source)? I see that SW4STM32 uses GNU ARM Embedded Toolchain. And there must be one careful about libraries it uses, because for example libc is the “newlib” licensed under a set of different licences. Does SW4STM32 changes the license of used GNU ARM Embedded Toolchain somehow?

Hi Jan,

No, we do not change the licenses in any way and the code produced by SW4STM32 is totally free to be used in commercial, closed source, products.

The ST-provided STM32 firmwares are protected by the ST Liberty license whose text is available in the firmwares and allow you to use them for commercial products running on any STM32 chip. A few third party softwares (like STemWin and PolarSSL) have the same kind of license.

Apart if you import by yourself some external library that has a more constrained license, any program created by SW4STM32 can be distributed under the license of uour choice, commercial or opensource.

Hi Bernard,

When I create a project using IDE for a perticular STM32 chip it auto-generates linker script. In this script you have the following copyright claim. If we had to share this file with a customer to proceed with development would that be an issue?
