Example FATFS + QSPI + USB MSC (eg Adafruit nRF52840 Feather)

[douglas.malnati]

Hi,

I have looked at the "mass" example showing how to expose a fatfs via USB MSC, that looks good.

I want to do this, but using the QSPI flash storage.

Is there an example I can see where to do that?

The 'mass' example shows using flash, but seemingly the flash of the nRF52840 itself, not external flash as I want.

For reference I'm starting on the ADafruit nRF52840 Feather, but will transfer later to a custom board with my own QSPI flash.

Side question, I've read on this forum compatibility issues using QSPI for NAND storage, which is different than the Feather, are there any concerns I should know about for Flash storage chips?

Thanks!

Hi,

Looks like the sample with this board support that already out-of-the-box. Just need to set this config:

CONFIG_APP_MSC_STORAGE_FLASH_FATFS=y
