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:

System Workbench for STM32

timer3 counter period. have to be a variable

when i configurate in MX timer3, i have to fill in for counter period a number, let say 1000.
but i need in my code a variable named: stepper_speed
so in time.c i changed 1000 for stepper_speed.
but every time when i go to MX, and after a change i go back, the code will build op again and change stepper_speed back to 1000.
do anyone nows ho i can avoid this ?
thanks in advanced.
