How to interface Single Mode SPI memory like M9501 or QUAD SPI at OSPI interface?

[VK Verma]

Hi,

I am using STM32L4R7VIT which is having OSPI interface and I have connected M9501 Memory which is the single SPI mode memory. I found no example in cube repository or in any post in community which interacted with this issue.

Hello @VK Verma,

To configure the OCTOSPI interface for Single SPI mode, I suggest you check AN5050 section 5.2 for OCTOSPI/HSPI configuration for Regular-command protocol.

Also, the AN5050 section 6 OCTOSPI application examples can help you to configure the OCTOSPI interface with different modes such as HyperBus, Octo-SPI and Quad-SPI.

I hope this help you!
