STM32F746G-DISCO+TOUCHGFX+QSPI - Problem

EEuge

Hello! Sorry for my bad English...

I have board STM32F746-DISCO.

I generated project with CUBEMX and TouchGFX Designer. It works very well - I can see background picture and buttons. Pictures are located in "ExtFlashSection".

But today, while uploading firmware to DISCO by Keil, I look to left bottom corner, there programmed adresses are displayed. And I saw, that programmed adresses are 0x8xxxxxxx only. Adresses of qspi (0x9xxxxxxx) are not programmed.

I looked at configuration of automatically generated project. I opened .SCT file

LR_IROM1 0x08000000 0x00200000  {    ; load region size_region
  intflash.bin 0x08000000 0x00200000  {  ; load address = execution address
   *.o (RESET, +First)
   *(InRoot$$Sections)
   .ANY (+RO)
  }
  RW_IRAM1 0x20000000 0x00030000  {  ; RW data
   .ANY (+RW +ZI)
  }
}
 

I added next code

LR_EROM1 0x90000000 0x01000000  {    ; load region size_region
  extflash.bin 0x90000000 0x01000000  {  ; load address = execution address
   *.o (ExtFlashSection)
  }
}
 

I added flash algoritm STM32F746G-DISCO_N25Q128

Good! while firmware loading I see addresses 0x9xxxxxxx. Good, pictures are in qspiflash,

But then code started, pictures are not loaded.

Program halt at

 static portTASK_FUNCTION( prvIdleTask, pvParameters ) 

on strings

    if( listCURRENT_LIST_LENGTH( &( pxReadyTasksLists[ tskIDLE_PRIORITY ] ) ) > ( UBaseType_t ) 1 )
            {
                taskYIELD();
            }

Help me to create project, which use qspi correctly.

This is my project https://cloud.mail.ru/public/3kwT/49vbFpq5i.

Вот по�?ледний вариант https://cloud.mail.ru/public/3kwT/49vbFpq5i

Он при прошивке шьет по адре�?ам 0x90000000, но при запу�?ке ви�?нет на указанных выше �?троках.

По�?мотрите на sct файл и на на�?тройки дебаггера, подозреваю проблемы там.

И еще - когда запу�?каю дизайнер - у мен�? нет кнопки дл�? прошивки платы дизайнером. Когда �? открываю в �?амом дизайнере проект под ди�?кавери, така�? кнопка е�?ть. Е�?ли �? генерирую проект �? помощью куба и из куба жму "execute" - такйо кнопки нет.
