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:

failed eclipse plug-in update to System Workbench for STM32 v1.12.1 release

@ bing: Thank You for Your support.
I didn’t understood the whole site location thing, but after looking at URL You gave me, I tried to update eclipse with

Name: System Workbench for STM32 - Bare Machine edition
Location: http://www.openstm32.org/Eclipse-updates/org.openstm32.system-workbench.betaQuestion

In this special case, I have a different error and it is the following:

An error occurred during the org.eclipse.equinox.internal.p2.engine.phases.CheckTrust phase.
session context was:(profile=epp.package.cpp, phase=org.eclipse.equinox.internal.p2.engine.phases.CheckTrust, operand=, action=).
Error reading signed content.
Exception in opening zip file: C:\eclipse\plugins\fr.ac6.mcu.debug_1.11.2.201612060912

After all, I didn’t found a work around.
