Application Note 333

Programming External Flash used with STM32 Devices

This application note explains a universal approach for programming an external flash memory connected to an STM32 microcontroller device.

An example is presented for STM32F769I-Discovery board with STM32F769NIH6 microcontroller and MX25L51245G NOR flash connected over quad-SPI. The demonstrated concepts can be similarly applied to other STM32 devices and flash memories.

The ZIP file associated with the application note contains reference projects implementing flash programming algorithms for some STM32 Discovery boards, as well as Blinky examples showing how to use them in the project.
