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). 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 STM32F723E Discovery board, is given below. This example assumes a Micron MX25L512 (64MB flash) connected to the Quad-SPI interface of the STM32F723IE. 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 STM32F723E Discovery uses the following port pins to interface the (Q)SPI flash.

Alternate function Port / Pin
QSPI_CLK PB2
QSPI_CS PB6
QSPI_D0 PC9
QSPI_D1 PC10
QSPI_D2 PE2
QSPI_D3 PD13
