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 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:
west build -b nrf52840_blip samples/subsys/fs/fat_fs
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.
