| FAT Filesystem Sample Application |
| ################################### |
| |
| Overview |
| ******** |
| |
| This sample app demonstrates use of the filesystem API and uses the FAT file |
| system driver to mount an SDHC card connected over SPI bus. |
| |
| Requirements |
| ************ |
| |
| This project requires a SDHC or microSD card formatted with FAT filesystem. |
| See the :ref:`SDHC_disks` documentation for Zephyr implementation details. |
| |
| Building and Running |
| ******************** |
| |
| This sample can be built for an ``nrf52840_blip`` board. It requires |
| both the ``nrf52840_blip.overlay`` and the ``dts_fixup.h`` for nrf52840_blip |
| to work: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/subsys/fs |
| :board: nrf52840_blip |
| :goals: build |
| :compact: |
| |
| To run this sample, a FAT formatted microSD card should be present in the |
| microSD slot of ``nrf52840_blip`` board. If there are any files or directories |
| present in the card, the sample lists them out on the debug serial output. |
