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:

FPU going too slow

Hi, really can’t tell until you show the whole “offending” disassembly code.

General advices:

1. turn on the optimizations (-O2 or -O3) so that GCC can optimize the loops and.. the other things :-)
2. use e.g. 1.0f instead of 1.0 (in C standard the latter is double while the former is float, STM32F4 hardware supports only float)
