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:

Video: Simultaneous debug of Linux and bare-metal applications.
Video: Motor control by gestures (image processing on Cortex-A7/Linux, real-time on bare metal Cortex-M4).
White paper: Asymmetric Multi-Programming with System Workbench for Linux.
White paper: Creating an STM32MP1 Linux platform with System Workbench for Linux.

Hi Joan,

It looks like there is a conflict with the ST-Link/V2-1 driver.

You can try this solution : http://www.openstm32.org/tiki-view_faq.php?faqId=1#q3
Or reinstall the driver providen by ST.

Here the link to download the latest ST-Link/V2-1 driver (Vista, Win7, Win8) : http://www.st.com/web/catalog/tools/FM147/SC1887/PF260218

Hope it will solve the problem,
Kevin.
