Re: Full example of using spiffs with ESP32

@loboris, My question might be silly, but i'm having trouble in flashing the SPIFFS image in to my ESP32 and i'm getting below error when executing "make copyfs",

Code: Select all

make: *** No rule to make target `copyfs'.  Stop.


I would be grateful if anyone could tell me what i'm missing here.

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 repository

Code: Select all

git clone https://github.com/loboris/ESP32_spiffs_example.git


Execute menuconfig and configure your Serial flash config and other settings. Included sdkconfig.defaults sets some defaults to be used.
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.

Code: Select all

make menuconfig

Make and flash the example.

Code: Select all

make all && make flash


Features

  • 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

When using file related functions which has filename argument, prefix /spiffs/ has to be added to the file name.

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:

Code: Select all

make makefs

to create spiffs image in build directory without flashing to ESP32

Execute:

Code: Select all

make flashfs

to create spiffs image in *build* directory and flash it to ESP32

Execute:

Code: Select all

make copyfs

to flash prepared components/spiffs_image/spiffs_image.img to ESP32

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

INTRODUCTION

Spiffs is a file system intended for SPI NOR flash devices on embedded targets.
Spiffs is designed with following characteristics in mind:

  * Small (embedded) targets, sparse RAM without heap
  * Only big areas of data (blocks) can be erased
  * An erase will reset all bits in block to ones
  * Writing pulls one to zeroes
  * Zeroes can only be pulled to ones by erase
  * Wear leveling

There were some changes in latest esp-idf which prevented make makefs|flashfs|copyfs to be executed.

The repository is updated with necessary fixes and it works now. Please, pull the changes.

Update:

  • SPIFFS LOCK/UNLOCK (mutex) added to make spiffs operations thread safe
  • MultiTask test added to example application

If you are using spiffs in some other projects, please copy spiffs directory from this repository to your project.
Only the files spiffs_vfs.c and spiffs_config.h are changed.

Thank you for your work! As a new to ESP32 your repositories have helped me a lot.

Hi I have some issue compiling this library...
I posted it as issue on the git.. https://github.com/loboris/ESP32_spiffs ... e/issues/5

Can someone tell me whats the problem ?

this is what happens on compiling .

Code: Select all

...

It looks like the problem is with esp-idf version used.

If using the master branch, always update to the latest commit:
cd to your esp-idf directory, then execute:

Code: Select all

git pull
git submodule update --init --recursive
After that the build should finish without error.

Note: After updating esp-idf you must (almost) always run

Code: Select all

make menuconfig
in your project directory first.

If you are using the older esp-idf commit, or release branch (v2.0 or v2.1), here is the solution:

delete (or rename - add .back extension) the files:
components/mkspiffs/component.mk and
components/spiffs_image/component.mk

After that the build should finish without error.

Any difference with your SPIFFS implementation and the one on ESP-IDF ?

The spiffs implementation which is now included in esp-idf is mostly the same as mine, so there is not much reason to use the library which I've proposed.

The only difference of which I'm aware is that my implementation has full support for file's timestamp (atime,mtime,ctime) which is missing from esp-idf/spiffs.
It is important for my applications, so I will continue to use my spiffs implementation for now.
