Tool to build and unpack SPIFFS images.
mkspiffs {-c <pack_dir>|-u <dest_dir>|-l|-i} [-d <0-5>] [-b <number>]
[-p <number>] [-s <number>] [--] [--version] [-h]
<image_file>
Where:
-c <pack_dir>, --create <pack_dir>
(OR required) create spiffs image from a directory
-- OR --
-u <dest_dir>, --unpack <dest_dir>
(OR required) unpack spiffs image to a directory
-- OR --
-l, --list
(OR required) list files in spiffs image
-- OR --
-i, --visualize
(OR required) visualize spiffs image
-d <0-5>, --debug <0-5>
Debug level. 0 means no debug output.
-b <number>, --block <number>
fs block size, in bytes
-p <number>, --page <number>
fs page size, in bytes
-s <number>, --size <number>
fs image size, in bytes
--, --ignore_rest
Ignores the rest of the labeled arguments following this flag.
--version
Displays version information and exits.
-h, --help
Displays usage information and exits.
<image_file>
(required) spiffs image file
You need gcc (≥4.8) or clang(≥600.0.57), and make. On Windows, use MinGW.
Run:
$ git submodule update --init
$ make distSome SPIFFS options which are set at mkspiffs build time affect the format of the generated filesystem image. Make sure such options are set to the same values when builing mkspiffs and when building the application which uses SPIFFS.
These options include:
- SPIFFS_OBJ_NAME_LEN
- SPIFFS_OBJ_META_LEN
- SPIFFS_USE_MAGIC
- SPIFFS_USE_MAGIC_LENGTH
- SPIFFS_ALIGNED_OBJECT_INDEX_TABLES
- possibly others
To see the default values of these options, check include/spiffs_config.h file in this repository.
To override some options at build time, pass extra CPPFLAGS to make. You can also set BUILD_CONFIG_NAME variable to distinguish the built binary:
$ make clean
$ make dist CPPFLAGS="-DSPIFFS_OBJ_META_LEN=4" BUILD_CONFIG_NAME=-customTo check which options were set when building mkspiffs, use --version command:
$ mkspiffs --version
