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.

Delays not working STM32F446RE

What do you mean by “not working”?

Looking at your code, anyway, even if you run the core at only 16MHz (the default at reset), a 50000 loop, if correctly optimized by the compiler, may run for only 5 to 10 ms, meaning the blinking will be totally invisible.

Try first by increasing a lot the loop delay (from 50,000 to 5,000,000 for example, or even more if you run at 480MHz) and see what happens.
