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:

System Workbench for STM32

Connect to custom board STM32L053 - STLINK-V2 - SWD


I updated AC6 framework to the last compiler + openOCD.
I can’t connect anymore to my stm32l476 based board. (Modifying stm32l4.cfg reset configuration is no longer working)

It seems the reset configuration is forced elsewhere:
srst_only separate srst_nogate srst_open_drain connect_assert_srst

here is the complete openocd log.

Please help, I’m stuck in a rut !!
Thanks for your help,
