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.
