menu "SPIFFS Configuration" config SPIFFS_MAX_PARTITIONS int "Maximum Number of Partitions" default 3 range 1 10 help Define maximum number of partitions that can be mounted. menu "SPIFFS Cache Configuration" config SPIFFS_CACHE bool "Enable SPIFFS Cache" default "y" help Enables/disable memory read caching of nucleus file system operations. config SPIFFS_CACHE_WR bool "Enable SPIFFS Write Caching" default "y" depends on SPIFFS_CACHE help Enables memory write caching for file descriptors in hydrogen. config SPIFFS_CACHE_STATS bool "Enable SPIFFS Cache Statistics" default "n" depends on SPIFFS_CACHE help Enable/disable statistics on caching. Debug/test purpose only. endmenu config SPIFFS_PAGE_CHECK bool "Enable SPIFFS Page Check" default "y" help Always check header of each accessed page to ensure consistent state. If enabled it will increase number of reads from flash, especially if cache is disabled. config SPIFFS_GC_MAX_RUNS int "Set Maximum GC Runs" default 10 range 1 10000 help Define maximum number of GC runs to perform to reach desired free pages. config SPIFFS_GC_STATS bool "Enable SPIFFS GC Statistics" default "n" help Enable/disable statistics on gc. Debug/test purpose only. config SPIFFS_PAGE_SIZE int "SPIFFS logical page size" default 256 range 256 1024 help Logical page size of SPIFFS partition, in bytes. Must be multiple of flash page size (which is usually 256 bytes). Larger page sizes reduce overhead when storing large files, and improve filesystem performance when reading large files. Smaller page sizes reduce overhead when storing small (< page size) files. config SPIFFS_OBJ_NAME_LEN int "Set SPIFFS Maximum Name Length" default 32 range 1 256 help Object name maximum length. Note that this length include the zero-termination character, meaning maximum string of characters can at most be SPIFFS_OBJ_NAME_LEN - 1. SPIFFS_OBJ_NAME_LEN + SPIFFS_META_LENGTH should not exceed SPIFFS_PAGE_SIZE - 64. config SPIFFS_FOLLOW_SYMLINKS bool "Enable symbolic links for image creation" default "n" help If this option is enabled, symbolic links are taken into account during partition image creation. config SPIFFS_USE_MAGIC bool "Enable SPIFFS Filesystem Magic" default "y" help Enable this to have an identifiable spiffs filesystem. This will look for a magic in all sectors to determine if this is a valid spiffs system or not at mount time. config SPIFFS_USE_MAGIC_LENGTH bool "Enable SPIFFS Filesystem Length Magic" default "y" depends on SPIFFS_USE_MAGIC help If this option is enabled, the magic will also be dependent on the length of the filesystem. For example, a filesystem configured and formatted for 4 megabytes will not be accepted for mounting with a configuration defining the filesystem as 2 megabytes. config SPIFFS_META_LENGTH int "Size of per-file metadata field" default 4 help This option sets the number of extra bytes stored in the file header. These bytes can be used in an application-specific manner. Set this to at least 4 bytes to enable support for saving file modification time. SPIFFS_OBJ_NAME_LEN + SPIFFS_META_LENGTH should not exceed SPIFFS_PAGE_SIZE - 64. config SPIFFS_USE_MTIME bool "Save file modification time" default "y" depends on SPIFFS_META_LENGTH >= 4 help If enabled, then the first 4 bytes of per-file metadata will be used to store file modification time (mtime), accessible through stat/fstat functions. Modification time is updated when the file is opened. config SPIFFS_MTIME_WIDE_64_BITS bool "The time field occupies 64 bits in the image instead of 32 bits" default n depends on SPIFFS_META_LENGTH >= 8 help If this option is not set, the time field is 32 bits (up to 2106 year), otherwise it is 64 bits and make sure it matches SPIFFS_META_LENGTH. If the chip already has the spiffs image with the time field = 32 bits then this option cannot be applied in this case. Erase it first before using this option. To resolve the Y2K38 problem for the spiffs, use a toolchain with 64-bit time_t support. menu "Debug Configuration" config SPIFFS_DBG bool "Enable general SPIFFS debug" default "n" help Enabling this option will print general debug messages to the console. config SPIFFS_API_DBG bool "Enable SPIFFS API debug" default "n" help Enabling this option will print API debug messages to the console. config SPIFFS_GC_DBG bool "Enable SPIFFS Garbage Cleaner debug" default "n" help Enabling this option will print GC debug messages to the console. config SPIFFS_CACHE_DBG bool "Enable SPIFFS Cache debug" default "n" depends on SPIFFS_CACHE help Enabling this option will print cache debug messages to the console. config SPIFFS_CHECK_DBG bool "Enable SPIFFS Filesystem Check debug" default "n" help Enabling this option will print Filesystem Check debug messages to the console. config SPIFFS_TEST_VISUALISATION bool "Enable SPIFFS Filesystem Visualization" default "n" help Enable this option to enable SPIFFS_vis function in the API. endmenu endmenu
