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 two short videos (registration required) highlighting:

Converting to C++

In fact, not only you should correct the linker script specification (use a relative path, like ..\STM32F746NGHx_FLASH.ld rather than an absolute one), but you also must add linker flags -specs=nosys.specs -specs=nano.specs in C/C++ Build >> Settings >> MCU G++ Linker >> Miscellaneous

Then the project should compile correctly.

These are glitches in C to C++ conversion that will be corrected in a future release.
