where *files* is the directory with files that should go into SPIFFS image.
Or you can build mkspiffs manually with:
mkspiffs can be built separately. Simply run `make` in the mkspiffs directory.
To manually generate SPIFFS image from a directory SPIFFS configuration must be
provided as command line arguments.
Arguments:
* -D Directory with files that will be put in SPIFFS image.
* -f SPIFFS image file name.
* -s SPIFFS size.
* -p Logical page size.
* -b Logical block size.
All arguments are mandatory.
For example:
```
make SPIFFS_SIZE=0x100000
```
mkspiffs cannot be built without specifying SPIFFS size because it uses the
same SPIFFS sources as the firmware. And for the firmware SPIFFS size is
compile time defined.
Please note that if you change SPIFFS_SIZE you need to rebuild mkspiffs.
The easiest way is to run `make clean` for you project.
To manually generate SPIFFS image from directory, run:
```
mkspiffs DIRECTORY IMAGE_NAME
mkspiffs -D ./my_files -f spiffs.img -s 0x10000 -p 256 -b 8192
```
