QSPI Flash Programming Support

Before continuing with this article, please read the generic article about QSPI flash programming support on STM32F7 devices (STM32F7 (Q)SPI support).

Example implementation

As described in the generic article, the reference flash algorithm is based on the SEGGER Open Flashloader and therefore needs to be added manually using a JLinkDevices.xml file. An example JLinkDevices.xml file as well as pinout used on the STM32F769I EVAL board, is given below. This example assumes a Micron N25Q512A (64MB flash) connected to the Quad-SPI interface of the STM32F769. For further information regarding the Open Flashloader and how to use the JLinkDevices.xml file, please refer to the J-Link User Manual (UM08001), chapter 10 Open Flash Loader.

Quad-SPI Interface Pins

The ST STM32F769I EVAL uses the following port pins to interface the (Q)SPI flash.

Alternate function Port / Pin
QSPI_CLK PB2
QSPI_CS PB6
QSPI_D0 PF8
QSPI_D1 PF9
QSPI_D2 PF7
QSPI_D3 PF6
