make: *** No rule to make target `copyfs'. Stop.Let alone making a new image, i'm even unable to flash the one given by you in the example repository. Also i'm running this on Mac OS X.

How to build
Configure your esp32 build environment as for other esp-idf examples
Clone the repositoryExecute menuconfig and configure your Serial flash config and other settings. Included sdkconfig.defaults sets some defaults to be used.Code: Select all
git clone https://github.com/loboris/ESP32_spiffs_example.git
Navigate to SPIffs Example Configuration and set SPIFFS options.
Select if you want to use wifi (recommended) to get the time from NTP server and set your WiFi SSID and password.Make and flash the example.Code: Select all
make menuconfigFeaturesCode: Select all
make all && make flash
When using file related functions which has filename argument, prefix /spiffs/ has to be added to the file name.
- full implementation of spiffs with VFS
- directories are supported
- file timestamp is added to standard spiffs
- example of list directory functions
- example of file copy functions
Prepare SPIFFS image
It is not required to prepare the image, as the spiffs will be automatically formated on first use, but it might be convenient.
SFPIFFS image can be prepared on host and flashed to ESP32.
New: Tested and works under Linux, Windows and Mac OS.
Copy the files to be included on spiffs into components/spiffs_image/image/ directory. Subdirectories can also be added.

Execute:to create spiffs image in *build* directory and flash it to ESP32Code: Select all

Execute:to flash prepared components/spiffs_image/spiffs_image.img to ESP32Code: Select all
make copyfs
Example functions
- get the time from NTP server and set the system time (if WiFi is enabled)
- register spiffs as VFS file system; if the fs is not formated (1st start) it will be formated and mounted
- perform some file system tests
- write text to file
- read the file back
- make directory
- copy file
- remove file
- remove directory
- list files in root directory and subdirectories
