CONFIG_APP_MSC_STORAGE_RAM VS FLASH_FATFS

[Sergnrf]

Hi Team,
NCS v2.3.0
nrf52840

my project works as expected with CONFIG_APP_MSC_STORAGE_RAM=y

but I need storage FLASH_FATFS

I set CONFIG_APP_MSC_STORAGE_FLASH_FATFS=y
and the disk does not open in Windows, it gives an error window when connecting nrf USB.

Thank you.

Hi,

Have you tried using the sample 275880_mass_v2.2.0.zip provided here? I have tested it and it is working in NCS v2.2.0.

Please find below the log from my nRF52840-DK.

I use NCS v2.3.0, Mass example works, but I need this functionality to work in the Сhat example, I added the archive with the project, look at the errors it gives, this is an urgent problem, thanks.
