.. zephyr:code-sample:: fs-format
:name: Format filesystem
:relevant-api: file_system_api
Format different storage devices for different file systems.
Overview
***********
This sample shows how to format different storage
devices for different file systems. There are 2 scenarios prepared for this
sample:
* littleFS on flash device
* FAT file system on RAM disk
Building and running
********************
To run this sample, build it for the desired board and scenario and flash it.
The Flash scenario is supported on the nrf52dk/nrf52832 board.
The RAM disk scenario is supported on the mimxrt1064_evk board.
To build the RAM disk sample, the configuration :file:`prj_ram.conf` needs to be used by setting
``CONF_FILE=prj_ram.conf``.
The Flash sample for the nrf 52DK board can be built as follow:
.. zephyr-app-commands::
:zephyr-app: samples/subsys/fs/format
:board: nrf52dk/nrf52832
:goals: build flash
:compact:
The RAM disk sample for the MIMXRT1064-EVK board can be built as follow:
.. zephyr-app-commands::
:zephyr-app: samples/subsys/fs/format
:board: mimxrt1064_evk
:conf: "prj_ram.conf"
:goals: build flash
:compact:
Sample Output
=============
When the sample runs successfully you should see following message on the screen:
.. code-block:: console
I: LittleFS version 2.4, disk version 2.0
I: FS at flash-controller@4001e000:0x7a000 is 6 0x1000-byte blocks with 512 cycle
I: sizes: rd 16 ; pr 16 ; ca 64 ; la 32
I: Format successful
