QSPI on STM32H750B-DK & NUCLEO-H743ZI2

[StanCosgrove]

Hi I m contemplating QSPI communication between the aforementioned 2 EVK to a FPGA board, anyone can advise any step by step tutorial using QSPI master & slave? Or any tutorial on QSPI with external flash ?? TQ.

Hello @StanCosgrove and welcome to the Community 🙂

For the QSPI with external flash, I recommend you to check the following resources:

• AN4760 Quad-SPI interface on STM32 microcontrollers and microprocessors
• MOOC - External QSPI loader how to

I see this is from a few months ago, but a similar slave question came up again.

No you can't be a QSPI,OSPI,XSPI slave with any of the STM32 currently available, much better done with a CPLD/FPGA.

Want two boards to communicate, perhaps implement a FIFO memory slave, or some thing supporting Dual Port RAM

Examples, perhaps check BSP or QSPI/OSPI examples

The schematic for the NUCLEO-H743ZI2 board (see under CAD Resources tab) should identify the QSPI signal positions on the connector header. CLK, NCS, IO0, IO1, IO2 and IO3
