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();
}

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)
