In order to use file system in a project the following steps should be made:
* Add SPIFFS component in a project Makefile `EXTRA_COMPONENTS = extras/spiffs`
* Specify your flash size in the Makefile `FLASH_SIZE = 32`
* Specify your flash size in the Makefile `FLASH_SIZE = 4`
* Specify the start address of file system region on the flash memory
`SPIFFS_BASE_ADDR = 0x200000`. It still needed even for `SPIFFS_SINGLETON = 0`
in order to flash SPIFFS image to the right location during `make flash`.
