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:

Can't flash STM32L476

Hello Håkan, Romain,

Håkan,
>> NRST seem to be connected correctly
OK, to confirm that using ST-Link Utilty > Menu (Target > Settings) : select Mode = Connect Under Reset & Reset Mode = Hardware Reset
and check if that ST-Link Utility cann connect to your board.

>> and I guess that pin is used by the “STM32 ST-LINK Utility” too witch successfully can flash the MCU.
No, ST-Link Utility can connect to your device using different reset modes (selectable from Target > Settings):

Connection ModePossible Reset Modes
Connect Under ResetHardware Reset
Normal(Software System / Core / Hardware) Reset
HotplugNo Reset


Romain
>> I already had the same error because of a debug session not stopped...
When a debug session is not stopped a different message appears saying that openOCD cannot connect to MCU, but in this case there is a reset timeout.

Best Regards,
Tarek
