QSPI Flash Programming Support
Before continuing with this article, please read the generic article about QSPI flash programming support on STM32U5 devices ( STM32U5 (Octa)SPI support).
In contrast to the other QSPI flash programming implementations for STM32, support has been added internally through the JLinkARM.dll and not through an open flash loader. So in case you need an open flash loader with another pin config, please get in contact with Segger directly via our support system: https://www.segger.com/ticket/
For further information how to include a open flash loader into your J-Link software, please refer to:
Quad-SPI Interface Pins
The ST STM32U585I-Discovery kit uses the following port pins to interface the (Octa)SPI flash.
