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.

Alternate function Port / Pin
OCTASPI_CLK PF4
OCTASPI_CS PI5
OCTASPI_BK0_D0 PF0
OCTASPI_BK0_D1 PF1
OCTASPI_BK0_D2 PF2
OCTASPI_BK0_D3 PF3
OCTASPI_BK1_D0 PH9
OCTASPI_BK1_D1 PH10
OCTASPI_BK1_D2 PH11
OCTASPI_BK1_D3 PH12
