Looking for USB MSC + nRF52840 internal flash + FATFS sample

[bluemountain]

Hi, DEVZONE, 

nRF52840DK

nRF connect SDK,  v3.0.1

sample :    ~~\ncs\v3.0.1\zephyr\samples\subsys\usb\mass

it has    internal ram-based FAT,  external-Flash FAT configuration, but it doesn't have internal-Flash + FAT configuration.

Can someone suggest any sample for it ?

Or can someone teach me how to update the sample code to use internal flash ?

Regards,

[Kenneth]

This seems relevant:
Is it supported to configure one LittleFS partition on external SPI flash and another in internal FLASH?
