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:

Redirecting printf() does not work

Hi Moha1993, if you are using floats there is a way to enable float support in printf :
By default “nano” version of the standard input-output (stdio) library is selected.
This helps to keep code size low but does not allow use float numbers in printf
In order to change it, disable “nano” library option within project settings :
Remove this option : -spec=nano.specs in C/C++ Build -> Settings -> MCU GCC Linker -> Miscellaneous
