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:

This release provides the following improvements:

*Update of ARM toolchain to 2017-q2 release (6.3) excepting GDB
*Migration of build tools to MSYS2 for windows OS
*The support of STLinkServer, an application allowing:
  1. to share the debug interface of a single ST-LINK board among several host applications. Typically a debugging tool and a monitoring tool. Of course, two debugging tools can’t control simultaneously the same target, but both may have access to it, if choosing appropriate connection settings.
  2. to have access to several boards with one tool to launch and control several debugs in several boards.

The host application must have the ability to connect to the ST-LINK server instead of connecting directly to the ST-LINK USB.
Installation:
ST-Link Server is delivered and installed by the SW4STM32 installer. There must be only one installation of ST-Link Server per machine, that is why the location of installation folder cannot be edited and depends on the operating system.
If the version 2.2.0 has been installed with the update site procedure, the ST-Link Server will not be installed. In that case, download the last SW4STM32 installer or download the ST-Link Server on the st.com website.
Manual installation:
Windows: Double click on the msi file will launch an installation wizard for the ST-Link Server.
Linux: The file is a rpm or deb package, use command line “sudo dpkg -i st-stlink-server-xxx.deb”.
MacOS: Double click on the pkg file will launch an installation wizard for the ST-Link Server.
Usage:
Once activated, the total number of connected boards is indicated and a table listing these boards is displayed. A board must be selected before launching the debug session.
Debug DebugConfiguration DebuggerTab STLinkClientGroup

Limitation:
Boards with firmware’s version lower than j28 cannot be selected to launch the debug using STLinkServer. In this case, the user must use the classical debug.

This release provides the following fixes:

  • Fix ARM Tools chain decompression issue.
  • Fix float formatting issue with newlib nano : raise an error when %f is used with scanf and printf without corresponding Linker option ‘-u _printf_float’ or ‘-u _scanf_float’

WARNING :

  • Installers need at least 600Mo free space on the installation volume
  • The new CDT Debug Console, that offers a powerful GDB console, is not supported yet.
  • In some Linux environments the Welcome screen rendering could appear messy (empty page, missing icons). This is generally caused by an unresolved WebKit1 library required by SWT for GTK2. To restore this display issue it is advised to install the following package: $ sudo apt-get install libwebkitgtk-1.0-0
  • On Ubuntu, version 14.04 is now required to run System Workbench for STM32
  • For MAC OSX Users : Due to missing path to JRE, some users could not launch the installer. This issue is now fixed. For users who have installed the Oracle Java JDK, the old/new installers are still working.
