xspi problem on stm32h7r7

[totoro]

Hi,

I used cubemx to generate three projects (Boot, Appli and ExtMemLoader) of STM32H7R7, the boot project was responsible for initializing Octol SPI FLASH, but the initialization failed, and I couldn't jump to the app.

I followed this tutorial to configure cubemx:

https://community.st.com/t5/stm32-online-courses/stm32h7rs-and-ospi-in-practice/ba-p/810411 

the hardware:

  board: art-pi2 (art-pi2 )
  mcu: STM32H7R7L8HxH
  Octal Spi Flash: W35T51NW (datasheet )

developt env:  STM32CubeMX 6.15.0
  STM32CubeCLT 1.19.0
  STM32Cube for Visual Studio Code  2.1.1
  STM32CubeProgrammer 2.20.0

the attachment is the project included cubemx project

In stm32_extmem_conf.h file, print debugging is turned on

#define EXTMEM_DRIVER_NOR_SFDP_DEBUG_LEVEL 4
#define EXTMEM_MACRO_DEBUG printf
