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

Unable to install Cube HAL in firmware configuration.


1) Removed all ST related software and all Eclipse versions except 2019-12.

2) Downloaded ST Workbench directly and did not install it as a plugin. It is in /Applications/Ac6.

3) Eclipse works and I installed STM software as directed in Eclipse.

4) When I make a new project, the firmware never downloads. I waited over three hours. Procedure:

a) Create a new C or C++ project

b) Click C Managed Build template

c) Under C Project, give it the name “03.blink” and choose Ac6 STM32 MCU project with toolchain Ac6 STM32 MCU GCC

d) Under Select Configurations, I uncheck “Release” and leave “Debug” checked.

e) Under Target Configuration, I choose board NUCLEO-F030R8

f) Under Firmware Configuration, I choose Hardware Abstraction Layer (Cube HAL).

i) I click Firmware Installation

ii) On the next page, there is only one repository: /Users/tom/.ac6/SW4STM32/firmwares. This is likely wrong. I need the link that should be used.

I also notice that when I just go to Cube HAL and click Download Target Firmware, it initiates a download. This is very slow. It shows a 256 MB limit. The counter slowly increases but never gets to 256 MB. Then it changes to a lower number. I guess it’s opening several connections. None ever finish.
