Fields
Field
Declared as
Description
bool
If FAT partition can not be mounted, and this parameter is true, create partition table and format the filesystem.
size_t
If format_if_mount_failed is set, and mount fails, format the card with given allocation unit size. Must be a power of 2, between sector size and 128 * sector size. For SD cards, sector size is always 512 bytes. For wear_levelling, sector size is determined by CONFIG_WL_SECTOR_SIZE option. Using larger allocation unit size will result in higher read/write performance and higher overhead when storing small files. Setting this field to 0 will result in allocation unit set to the sector size.
bool
Enables real ff_disk_status function implementation for SD cards (ff_sdmmc_status). Possibly slows down IO performance. Try to enable if you need to handle situations when SD cards are not unmounted properly before physical removal or you are experiencing issues with SD cards. Doesn't do anything for other memory storage media.
bool
Use 1 FAT (File Allocation Tables) instead of 2. This decreases reliability, but makes more space available (usually only one sector). Note that this option has effect only when the filesystem is formatted. When mounting an already-formatted partition, the actual number of FATs may be different.

Function
Description
Convenience function to initialize FAT filesystem in SPI flash and register it in VFS This is an all-in-one function which does the following: - finds the partition with defined partition_label. Partition label should be configured in the partition table. - initializes flash wear levelling library on top of the given partition - mounts FAT partition using FATFS library on top of flash wear levelling library - registers FATFS library with VFS, with prefix given by base_prefix variable This function is intended to make example code more compact.
Convenience function to get FAT filesystem on SD card registered in VFS This is an all-in-one function which does the following: - initializes SDMMC driver or SPI driver with configuration in host_config - initializes SD card with configuration in slot_config - mounts FAT partition on SD card using FATFS library, with configuration in mount_config - registers FATFS library with VFS, with prefix given by base_prefix variable This function is intended to make example code more compact. For real world applications, developers should implement the logic of probing SD card, locating and mounting partition, and registering FATFS in VFS, with proper error checking and handling of exceptional conditions.
