CONFIG_SPIFFS_PAGE_SIZE
SPIFFS logical page size
Found in: Component config
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.
Range:
• from 256 to 1024
Default value:
• 256
CONFIG_SPIFFS_OBJ_NAME_LEN
Set SPIFFS Maximum Name Length
Found in: Component config
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.
Range:
• from 1 to 256
Default value:
• 32
CONFIG_SPIFFS_FOLLOW_SYMLINKS
Enable symbolic links for image creation
Found in: Component config
If this option is enabled, symbolic links are taken into account during partition image creation.
Default value:
• No (disabled)
CONFIG_SPIFFS_USE_MAGIC
Enable SPIFFS Filesystem Magic
Found in: Component config
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.
Default value:
• Yes (enabled)
CONFIG_SPIFFS_USE_MAGIC_LENGTH
Enable SPIFFS Filesystem Length Magic
Found in: Component config
If this option is enabled, the magic will also be dependent on the length of the filesystem. For exam-
ple, a filesystem configured and formatted for 4 megabytes will not be accepted for mounting with a
configuration defining the filesystem as 2 megabytes.
