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:

OpenOCD where to set SWD speed?

Posted by admin@micro-nova.com on 2016-02-03 23:41

Hello All,
I have a custom board with a STM32F030R8T6 processor, I am debugging using a ST-Link V2-1 on a nucleo board. For some reason I am only able to connec to my board at speeds up to 480 KHz using the ST-Link app. OpenOCD appears to always attempt to connect at 950 KHz and therefore always fails to connect. How do I go about requesting it connect at a lower speed?
Thanks!
Jason

Hello Jason,

You can use nucleo_f030r8.cfg placed in C:\Ac6\SystemWorkbench\plugins\fr.ac6.mcu.debug_1.6.0.xxxxxx\resources\openocd\scripts\st_board

and add the following command
adapter_khz 480
after this line
source [find target/stm32f0x_stlink.cfg]

Regards,
