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



The compiler and debugger are provided by Linaro as 32-bit programs; you should then install the 32-bit versions of the required libraries.

I know this is inconvenient, but we prefer to stick to the Linaro-provided compiler distribution as it is validated before release by Linaro, with an extensive test suite, something we could not do if we recompile it for 64-bit. So, as long as Linaro is only providing 332-bit Linux executables, you must install the needed 32-bit libraries.
