Hello, I'm using an STM32H750 MCU where I'm integrating the Crypto lib v4.0.1 I would like to execute this library (.text) from a specifc section. But I can manage to do what I want.

[DFell.1]

You can found below a extract of my linker script:

MEMORY
{
  D1_CODE_RAM (xrx) : ORIGIN = 0x24070000,   LENGTH = 64K
  FLASH       (rx) : ORIGIN = 0x8000000,    LENGTH = 128K
  NVRAM       (rx) : ORIGIN = 0x8020000,    LENGTH = 64K
}
 
.ram_code_load () :
{
    . = ALIGN(4);
    _sdata = .;        /* create a global symbol at data start */
    *(.ram_code_load)
    *(.ram_code_load*)
    *RestApiServer.o (.text .text*)
    *Cryptographic_CM7.a:*(.text .text*)
            
    KEEP(*(.ram_code_load))
    . = ALIGN(4);
    _edata = .;        /* define a global symbol at data end */
} >D1_CODE_RAM AT> NVRAM

What I expect is to found into my .map file the Cryptographic_CM7 .text code placed at 0x8020000 as it's done with RestApiServer.o code.

What I get is the Cryptographic_CM7 library .text code placed at 0x8000000...

Until now I had follow this PDF as ressources whitout any sucess. https://www.st.com/resource/en/application_note/an4296-use-stm32f3stm32g4-ccm-sram-with-iar-embedded-workbench-keil-mdkarm-stmicroelectronics-stm32cubeide-and-other-gnubased-toolchains-stmicroelectronics.pdf

Could someone provide me some help ?

Finally I manage to understand what was happening,

The code as shared is working properly, but in the full file I do have between line 6 and 8 (in the example above) the following line:

  .text :
  {
    . = ALIGN(4);
    *(.text)           /* .text sections (code) */
    *(.text*)          /* .text* sections (code) */
    . = ALIGN(4);
  } >FLASH

Since this line has been defined before the definition of the .ram_load_code section all the .text has been located into the FLASH region and not the NVRAM as wanted.
