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 two short videos (registration required) highlighting:

Sorry but I have misunderstood your question, thought you are talking about ITCM FLASH confused. It is not the case ?

Anyway, In my previous post I was talking about ITCM-FLASH.

If you want to load a specific function into a specific RAM region (in this case ITCM-RAM) you have to use the section feature:

example :

main.c
void routine_name __attribute__((section(".section_name"))) (void)
{
  // code
}

linker.ld
/*...................*/
/* Specify the memory areas */
MEMORY
{
ITCM_RAM (rx)      : ORIGIN = 0x00000000, LENGTH = 16K
FLASH (rx)             : ORIGIN = 0x00200000, LENGTH = 1024K
RAM (xrw)              : ORIGIN = 0x20000000, LENGTH = 320K
QSPI (xrw)              : ORIGIN = 0x90000000, LENGTH = 16M
}

/* Define output sections */
SECTIONS
{
/*........*/
 .section_name :
  {
    . = ALIGN(4);
    *(.section_name)         /* .section_name section */
    *(.section_name*)        /* .section_name* sub-sections if any */
    . = ALIGN(4);
  } >ITCM_RAM AT> FLASH
/*........*/
}



I hope that this can help you smile
