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 Macronix MT25TL01GHBB(128MB flash) connected to the Quad-SPI interface of the STM32H753XI. 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''.

QSPI Flash Programming Support

Before continuing with this article, please read the generic article about QSPI flash programming support on STM32H7 devices (STM32H7 (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 STM32H753I EVAL board, is given below. This example assumes a Macronix MT25TL01GHBB(128MB flash) connected to the Quad-SPI interface of the STM32H753XI. 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 STM32H753XI EVAL uses the following port pins to interface the (Q)SPI flash or dual (Q)SPI flash.

Alternate function Port / Pin
QSPI_CLK PB2
QSPI_CS PG6
QSPI_BK0_D0 PF8
QSPI_BK0_D1 PF9
QSPI_BK0_D2 PF7
QSPI_BK0_D3 PF6
Additonal pins for dual SPI FLASH Port / Pin
QSPI_BK1_D0 PH2
QSPI_BK1_D1 PH3
QSPI_BK1_D2 PG9
QSPI_BK1_D3 PG14

Flash algorithm (*.elf)

This file contains the program routines used by the J-Link DLL during flash programming for single SPI flash using the above described BK0 pins.

This file contains the program routines used by the J-Link DLL during flash programming for dual SPI flash using the above described BK0 and BK1 pins.
