Using ESP8266 SPIFFS

Read below what is the error root cause or jump straight to the resolution. This issue is attributed to Arduino IDE Boards Manager not cleaning up previous package installation before a new one is applied. As this is not done, then it is user responsibility to remove previous package before applying a new one. To prevent it from happening, if you are changing between staging and stablefirst press Remove button to delete currently used installation. There is no need to remove the installed package if you are changing it to another version without switching between staging and stable. Depending on selected module the error message is slightly different. If the issue already happens, then uninstalling and re-installing the package with Boards Manager typically will not fix it. Well, OK, fine. You will be able to fix it with Boards Manager. To do so, you need to carefully go step by step through the effort of removing new and then the old package. Once done you can install again the new package. The only difference is folder path. Example below shows the path for Windows. Note: If you are not sure which folder to delete, then remove both of them. Select ESP module and the issue should be resolved. If you are interested in more details, please refer to,, ESP Arduino Core latest. Edit on GitHub. How to Fix it? The folder location is at the very bottom of the Preferences window. Read the Docs v: latest Versions latest stable 2.

Even though file system is stored on the same flash chip as the program, programming new sketch will not modify file system contents. This allows to use file system to store sketch data, configuration files, or content for Web server. File system size depends on the flash chip size. Depending on the board which is selected in IDE, you have the following options for flash size:. Note: to use any of file system functions in the sketch, add the following include to the sketch:. Filesystem overhead on the flash is minimal as well. LittleFS is recently added and focuses on higher performance and directory support, but has higher filesystem and per-file overhead 4K minimum vs. They share a compatible API but have incompatible on-flash implementations, so it is important to choose one or the per project as attempting to mount a SPIFFS volume under LittleFS may result in a format operation and definitely will not preserve any files, and vice-versa. The actual File and Dir objects returned from either filesystem behave in the same manner and documentation is applicable to both. SPIFFS was selected because it is designed for small systems, but that comes at the cost of some simplifications and limitations. Practically speaking, that makes little difference though. Second, there is a limit of 32 chars in total for filenames. Warning : That limit is easily reached and if ignored, problems might go unnoticed because no error message will appear at compilation nor runtime. Opening files in subdirectories requires specifying the complete path to the file i. Subdirectories are automatically created when you attempt to create a file in a subdirectory, and when the last file in a subdirectory is removed the subdirectory itself is automatically deleted. Unlike SPIFFS, the actual file descriptors are allocated as requested by the application, so in low memory conditions you may not be able to open new files. Conversely, this also means that only file descriptors used will actually take space on the heap. It adds a menu item to Tools menu for uploading the contents of sketch data directory into ESP flash file system. Warning : Due to the move from the obsolete esptool-ck. This method allows you to configure the parameters of a filesystem before mounting. This method mounts file system. Returns true if file system was mounted successfully, false otherwise. Note that both methods will automatically format the filesystem if one is not detected. Formats the file system. May be called either before or after calling begin. Returns true if formatting was successful. Opens a file. Meaning of these modes is the same as for fopen C function. Returns File object. To check whether the file was opened successfully, use the boolean operator. Opens a directory given its absolute path.

We are a strong Community of developers, hackers, and visionaries. No, seriously, we are! Spiffs not supported on ESP Your new topic does not fit any of the above??? Check first. Then post here. Spiffs not supported on ESP I have the board defined as NodeMCU 1. Try IDE 1. I can not find the solution on the network for this. In the other hand, I can use other options to get a similar result from my webservers but I would like to resolve this, at least to get the knowhow. Does anyone have an idea of how to solve this issue? Regards Osvaldo.

Post your questions here until you graduate! Don't be shy. It all works apart from 1 thing. But programatically writing the same config file from my sketch results in garbage in the file which crashes the JSON parser leading to a stack dump. My understanding is that all ESP modules can use a reserved piece of Flash memory for a pseudo filesystem based on section 4. Code: Select all WriteConfigFile: contents of config. There is an issue with these chips and spiffs. I don't know if the work around is allready included in 2. For some reason, none of my Google searches brought me to the issues in the Arduino github. Here's a link to the issue and patch for others who might find this thread. The code change does not seem to have been commited to the Arduino codebase.
