@Ons KOOLI​ 

Thanks for reply.

​

As you mentioned that there are USB Disk and uSD of Fatfs.

I 'm looking for an example of FATFS running on external flash memory(N25Q128A) connected to the STM32F413 Discovery board.

​

Thanks.

Hi JLEE.6,

Unfortunately, There is no example provided by ST in the Firmware package.

But you can refer to these :

interface external flash to stm32 by fatfs

FATfs on STM32F767 and external Flash

FatFS on QSPI Flash

Fatfs on external flash

Best Regards,

Ons.

If you have working BSP code to erase, read, and write, then integrate that into the DISKIO layer.

Use 4KB sectors unless you're keen on managing the deblocking.

The NOR Flash erase/write will be SLOW
