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 )

development 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

  Boot print log:

Hello @totoro ,

 

Could you please enable the EXTMEM SALXSPI logging by adding the line #define EXTMEM_SAL_XSPI_DEBUG_LEVEL 2 to the stm32_extmem_conf.h file ?

Additionally, please dump the XSPI configuration registers between steps 9, 10, and 11 for further investigation.

 

Kind regards,

Thanks for the reply.

I have added the EXTMEMSALXSPIDEBUGLEVEL macro and printed the registers for XSPI2 in steps 9, 10 and 11

The location of the print is shown below.

Hello @totoro ,

Thanks for the dump of registers!

On the second reading of the SFDP signature (step 11), we can see that the memory has been configured in 1S8S8S mode.

By checking the XSPI register, we found the following:

  • IR => 0x5A (Read SFDP command)
  • AR => 0x0 (Address)
  • CCR => 0x04003401
    • DMODE = 1 => Data on one line
    • ADSIZE = 3 => 32-bit address
    • ADMODE = 4 => Address on eight lines
    • ISIZE = 0 => 8-bit instruction
    • IMODE = 1 => Instruction on one line
  • DTR is disabled for Instruction, Address, and Data
  • TCR = 8 => 8 dummy cycles

According to the memory datasheet, the READ SFDP command is only described for standard SPI and octal DDR modes.

Could you try modifying the following line in the function

SAL_XSPI_GetSFDP(SAL_XSPI_ObjectTypeDef *SalXspi, uint32_t Address, uint8_t *Data, uint32_t DataSize) 

if (s_command.AddressMode == HAL_XSPI_ADDRESS_1_LINE)

to

  if ((s_command.AddressMode == HAL_XSPI_ADDRESS_1_LINE) || (s_command.AddressMode == HAL_XSPI_ADDRESS_8_LINES))

Kind regards,

Hi,

It has been modified to what you said, and there are errors.

Hello @totoro 

 

Could you please comment out the second reading of the SFDP signature in the EMM driver, as well as the second reading of the ID ?

 

Kind regards

I transplanted this flash program from somewhere else, into mapping mode.

There are several modifications.
