STM32H7A3VIH6 Access QSPI

[amitpramanik]

Hello ,

I want to Access QSPI drivers in STM32H7A3VIH6. However in Cubemx there is only option of OCTOSPI1 and OCTASPI.

My question is there way to use QSPI api directly like HAL_QSPI_Init instead of OSPi init?
Or we have use OSPI only?

Secondly i am using 2 external flash to be used in each QUAD SPI.

Hello @amitpramanik and welcome to the community;

The STM32H7A3VIH6 device have an OCTOSPI interface. And the OCTOSPI supports the QuadSPI memories as mentioned in Overall FAQs for QUADSPI/OCTOSPI/HSPI/XSPI - STMicroelectronics Community. 

You can used the OSPI drivers to configure QuadSPI memories.

According to the Datasheet - STM32H7A3xI/G - 32-bit Arm® Cortex®-M7 280 MHz MCUs, up to 2-Mbyte Flash memory, 1.4-Mbyte RAM, 46 com. and analog interfaces, SMPS Table 1. STM32H7A3xI/G features and peripheral counts, the STM32H7A3VIH support only OCTOSPI interface.

 

If you need to use two QuadSPIs memories you can choose a device that supports two quad from those listed in table1. 

Thank you.
