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:

hi

Seems like i get the failure here :

/*##-4- Create and Open a new text file object with write access #####*/
if(f_open(&MyFile, “STM32.TXT”, FA_CREATE_ALWAYS | FA_WRITE) != FR_OK)
{
/* ‘STM32.TXT’ file Open for write Error */
Error_Handler();
}

and it do works in the imported exsample ....everything compile so i really do not understand

the main differences are the generated linker script (LinkerScript.ld) vs the original one (STM32F746NGHx_FLASH.ld)
and project settings (especially linker miscellaneous flags)

THANKS TAREK BOUCHKATI...

The linker files was the same but the solution was the missing linker instrulction as you can see in the attached images

I did try to google to learn was happend when setting -specs=nosys.specs -specs=nano.specs but can not see how it can influence on FATFS ..

But you are my hero today ;o)
