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:

Problems with OpenOCD

Found the default OpenOCD config file for the STM32L0xx processor in the AC6 directory and changed the debug configuration from Manual ‘ST-LinkV2-1’ / ‘SWD’ to ‘Use local script’.

Now I get a different error:

Error in final launch sequence
Failed to execute MI command:
-target-select remote localhost:3333

Error message from debugger back end:
localhost:3333: The system tried to join a drive to a directory on a joined drive.
localhost:3333: The system tried to join a drive to a directory on a joined drive.


From the OpenOCD console:

Open On-Chip Debugger 0.10.0-dev-00270-g7ec9836 (2016-05-18-14:26)

Error: Debug adapter does not support any transports? Check config file order.
Error: unable to select a session transport. Can’t continue.
shutdown command invoked


So it looks like it can’t find the transports file.
