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:

SW4STM32 and std::thread

Russian Federation

Hello,

is it possible to use the c++11 class std::thread for programming STM32 controllers? Can SW4STM32 generate a multithreading code without OS?

Thanks

std::thread is more of a STL thing. That comes from libc++ and boost etc.

But you have two threading options here: CMSIS(osThreadCreate) and FreeRTOS(xTaskCreate)

“Can SW4STM32 generate a multithreading code without OS?” - this will be your CMSIS option

Yes, I’d like to use right standart c++11 class. But when I try to compile the class std::thread it gives an error.

FreeRTOS looks like a kind of some patch: no classes, no methods, only c-functions. I have to write a some wrap for classes. And I’m not sure that this wrap will be enough good.

CMSIS RTOS is a same thing: you may use only c-style code.

Have I understood right: c++11 from SW4STM32 cannot generate code for std
thread, std
mutex etc? Or I can set some option and it will work properly... Is it possible?

You can not use C++ here.

C only.

You have equivalents for mutex and threads from the CMSIS and Freertos library.

Really I can :-)

I have written a wrap to FreeRTOS for classes. It includes tasks, semaphores, mutexes, events. Only timers are not included in it yet.

It’s a pity that SW4STM32 doesn’t support c++11 fully :-(
