QSPI Flash Programming Support

Before continuing with this article, please read the generic article about QSPI flash programming support on STM32L4 devices (STM32L446xx (Q)SPI support).

Example implementation

In contrast to the describtion in the generic article, the reference flash algorithm is included in the JLinkARM.dll and therefore needs not to be added manually using a JLinkDevices.xml file. The pinout used on the STM32L496 Discovery board, is given below. If you need another pin config please get in contact with SEGGER. So we can provide you an Open Flash Loader that is adapted for your pin config. For further information how to include a open flash loader into your J-Link software, please refer to: (Using a precompiled Flash Loader).

Quad-SPI Interface Pins

The ST STM32L476 Discovery uses the following port pins to interface the (Q)SPI flash.

Alternate function Port / Pin
QSPI_CLK PA3
QSPI_CS PB11
QSPI_D0 PB1
QSPI_D1 PB0
QSPI_D2 PA7
QSPI_D3 PA6
