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:

STM32L476G-EVAL and ST-LINK/V2 Connection Problem

Hi,

I don’t know, maybe use the internal STlink v2-1 for this.
Also, can you try to change the switch of Boot0 pin to 1 and reset.


Another idea, maybe the PCrop R/W protection is set too ?

Check that you have the “connect under reset” and “debug in low power modes” options activated.
Reset mode should be “Hardware Reset”.
And i have SWD at 1.8MHz.

Can you upgrade the STLink firmware ?
