How do I create a section in QSPI and put the array for the DAC there?

Greetings.

I have a microcontroller and QSPI flash. Everything works fine with TouchGFX. The pictures are stored in ExtFlashSection on the flash.

I need to store 3 large arrays for DAC. Tried adding to "STM32F746BGTX_FLASH.ld" except

ExtFlashSection :
	{
		*(ExtFlashSection ExtFlashSection.*)
		*(.gnu.linkonce.r.*)
        . = ALIGN(0x4);
	} >QUADSPI

section like this

MusicFlashSection :
	{
		*(MusicFlashSection MusicFlashSection.*)
		*(.gnu.linkonce.r.*)
        . = ALIGN(0x4);
	} >QUADSPI

also added in "Middlewares\ST\touchgfx\framework\include\touchgfx\hal\Config.hpp"

#define LOCATION_MUSICFLASH_PRAGMA LOCATION_PRAGMA("MusicFlashSection")

#define LOCATION_MUSICFLASH_ATTRIBUTE LOCATION_ATTRIBUTE("MusicFlashSection")

Build Analyzer did not show a new section.

Then I found an example C:\Users\User\STM32Cube\Repository\STM32Cube_FW_F7_V1.8.0\Projects\STM32746G-Discovery\Applications\QSPI\QSPI_perfs

and copied in my "STM32F746BGTX_FLASH.ld" 

.textqspi :
  {
    . = ALIGN(4);
    _qspi_start = .;        /* create a global symbol at qspi start */
    *(.textqspi)         /* .textqspi sections */
    *(.textqspi*)        /* .textqspi* sections */
    . = ALIGN(4);
    _qspi_end = .;         /* define a global symbols at end of textqspi */
    
  } >QSPI AT> FLASH

and

.textqspi : { *(.textqspi) } >QSPI

Added my arrays similar to the example, but Build Analyzer still didn't show a new section.

Can someone please tell me what I've missed? The analogy just didn't work and I don't know where or how to look for a solution.

 I programmed in CubeIDE.

 __attribute__((section(".textqspi")))

Yes of course I did it in a similar way to the example.

#ifndef _WAVE1_H
#define _WAVE1_H
 
#define NUM_ELEMENTS_1 13223
 
#ifndef IMG_NO_DATA
#if defined ( __ICCARM__ )
#pragma location = ".voiceqspi"
#else
__attribute__((section(".voiceqspi")))
#endif
 
const unsigned short Wave_1[13223] = {
2035, 2034, 2033, 2032, 2030, 2030, 2029, 2028, 2028, 2026,

2053, 2035, 2060};
#else
extern const unsigned char Wave_1[];
 
#endif
 
#endif

I found out what was wrong. Opened the UM2609(https://www.st.com/resource/en/user_manual/dm00629856-stm32cubeide-user-guide-stmicroelectronics.pdf) and read about the linker. I was just declaring my arrays, but I didn't refer to them anywhere in the code. I wanted to figure out how to store them first and then do the rest. Anyway, I unchecked the box and the linker did what I needed to do.
