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 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|
<Database> <Device> <ChipInfo Vendor="ST" Name="STM32F769NI" Core="JLINK_CORE_CORTEX_M7" /> <FlashBankInfo Name="QSPI Flash" BaseAddr="0x90000000" MaxSize="0x04000000" Loader="ST_STM32F769I_EVAL_QSPI.elf" LoaderType="FLASH_ALGO_TYPE_OPEN" /> </Device> </Database>
