Hi All!

I have a task to connect external flash with SPI interface to stm32f4xx. After that, I have to make fatfs on this flash.

Could anybody help me to find an example for doing this?

Thanks in advance for your help!!!!

Well there are SPI Flash and FatFs examples in the firmware libraries. You'll still have to own the integration, and deal with whatever flash erase block size issues there may be.

\STM32F4xx_DSP_StdPeriph_Lib_V1.4.0\Project\STM32F4xx_StdPeriph_Examples\SPI\SPI_FLASH
