# SPIFFS

## Creating an image

This implementation is supposed to be compatible with
images generated by the following tools:

* mkspiffs <https://github.com/igrr/mkspiffs>
* ESP-IDF spiffsgen.py <https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/storage/spiffs.html#spiffsgen-py>

Note: please ensure the following NuttX configs to be compatible with
these tools:

* CONFIG_SPIFFS_COMPAT_OLD_NUTTX is disabled
* CONFIG_SPIFFS_LEADING_SLASH=y

### mkspiffs

* Specify CONFIG_SPIFFS_NAME_MAX + 1 for SPIFFS_OBJ_NAME_LEN.
* Specify 0 for SPIFFS_OBJ_META_LEN.

### ESP-IDF spiffsgen.py

* Specify CONFIG_SPIFFS_NAME_MAX + 1 for the --obj-name-len option.
* Specify 0 for the --meta-len option.
