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:

Hi,

The error with the LIBUSB_ERROR_ACCESS and the “open failed” afterwards means there is an application that uses this STlink.

Are you sure there is not a “STM32 STLINK Utilities” running with the board connected for example ?

Or maybe you have a previous debug session not closed.
Check that there is no openocd.exe thread running in task manager.

For the STM32L152RBT6 mcu, this is important to use the same in your projects.
I mean, debugging a program made for STM32L152RC is not the same as STM32L152RB.
The disco with STM32L152RBT6 is maybe a very old one and is deprecated, that’s maybe why it isn’t supported in CubeL1.

Rgds,
Laurent
