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:

System Workbench for STM32

STM32 doesn't built it's own projects


To try to help you we need a bit more information about your setup:
- OS and version
- Installation mean installer or manual)
- Version of System Workbench fo STM32
- Installation path (should not include spaces in th epath)
- Java version (if installed separately)
Just saying: It does not work does not allow anybody to help you...
