STM32F746xx (Q)SPI support

The ST STM32F746xx device series comes with a QUADSPI controller which allows memory mapped read accesses to any (Q)SPI flash, connected to the Quad-SPI interface of the MCU. This allows the J-Link DLL to support flash programming through the Quad-SPI interface. Unfortunately, there is no generic way how to implement flash programming because the used pins to connect the SPI flash is not defined. Different pins can be used for the same QUADSPI alternate function and therefore, for each configuration, a slightly different RAMCode (different pin initialization / flash size) is required. We have developed a flash algorithm based on the ST STM32F746-DISCO evaluation board. This flash algorithm can be used to to program any common (Q)SPI flash, connected to the Quad-SPI interface of the ST STM32F746 device. The flash algorithm is based on the SEGGER Open Flashloader concept so it can easily be exchanged if a pin configuration, different from the one used in the example flash algorithm, is required. In such cases, please get in touch with SEGGER directly (support@segger.com).
