How to Interface and configure the STM32H563ZI with W25Q256 external memory

[Shubham08]

I was trying to interface W25Q256 with STM32H563ZI in QuadSPI mode as i have done with normal SPI it was working fine as i need to operate at higher frequency than normal spi for continous read and write operation. I tried to read Device information first but i was unable to read the device information mode. 

This is the parameter that i have set.

Also i have attached the programming file.

I need help in debugging the code and configuring the parameter in stm32cube ide if needed.

Hello @Shubham08,

Is the Quad mode enabled on both sides in order to communicate properly

- QUADSPI side

- Quad-spi memory side.

I recommend you to look at AN5050 Table 8 and check your OCTOSPI configuration.

 

Thank you.

Hello @Shubham08,

 

The W25Q256JV memory is a QUAD SPI memory and it’s configured in Quad-SPI mode. 

So, according to AN5050, the memory type has no impact in Quad-SPI mode.

 

Thank you.

Hello @Shubham08,

 

Thank you for updating post.

I noted some a wrong OCTOSPI configuration in your screenshot.

Sample shifting recommended to be enabled in STR mode and disabled in DTR mode.

Delay hold quarter cycle enabled in DTR mode and disabled in STR mode.

Chip select boundary (CSBOUND):The chip select must go high when crossing the page boundary (2^CSBOUND bytes defines the page size).

 

Thank you.
