| :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 `prj_ram.conf` needs to be used by setting `CONF_FILE=prj_ram.conf`. |
| |
| The Flash sample for the nrf 52DK board can be build 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 build 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 |
