Hello Support, 

 

I am not able to find the QSPI config in the STMCube 1.18.1version. I have attached the snapshot. According to the EvalBord it supports QSPI. 

CAN you guide me here for the setup. 

 

Best Reagrds,

Manikanta

QSPI is a subset of OCTOSPI1 here. Configure the OCTOSPI1 peripheral and ensure it uses the pins you expect.

Hello @mani9989;

 

The OCTOSPI interface is fully configurable and supports two, four or eight data lines: Single-SPI (traditional SPI), Dual-SPI, Quad-SPI and Octo-SPI.

You can configure the OCTOSPI on QUAD-SPI mode.

I recommend you to look at AN5050 precisely "Table 7. STM32CubeMX - Configuration of OCTOSPI signals and mode" , "Table 8. STM32CubeMX - Configuration of OCTOSPI parameters"  and "7.2 OCTOSPI configuration with STM32CubeMX" section and get inspired to configure the OCTOSPI on QUAD-SPI mode.

These tables can help you on how to configure the OCTOSPI with QUAD-SPI memory.

 

Thank you.
