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:

Motor control by gestures (image processing on Cortex-A7/Linux, real-time on bare metal Cortex-M4).
Simultaneous debug of Linux and bare-metal applications.
You can also view the recording of the System Workbench for Linux on the STM32MP1 SoC webinar.

Printf support for semihosting/ITM debugging for float variables.

I cannot get sprintf to work with floats either.

I checked the linker script and the _estack is fine

_estack = 0x20020000; /* end of RAM */

I am using an M4 and have the Hard FPU selected.

How do I enable printf with float?
