Serial.println('An Error has occurred while mounting SPIFFS')

Copy the following code to the main.cpp file and upload it to your board. Now, let’s just check if the file was actually saved into the ESP32 filesystem. Failed to connect to ESP32: Timed out waiting for packet header.

To solve this issue permanently, read the following article: If you start seeing a lot of dots on the debugging window and the filesystem image fails to upload, you need to press the on-board boot button once you start seeing the dots. This new folder must be called data, otherwise, it won’t work. Click on the New Folder icon to create a new folder. With your mouse, select the project folder you’re working on.

Getting Started with VS Code and PlatformIO IDE for ESP32 and ESP8266Ĭreate a folder called data inside your project folder.

If you’re not familiar with VS Code + PlatformIO, follow the next tutorial first: For you to understand how everything works, we’ll upload a. The files you want to upload to the ESP32 filesystem should be placed in a folder called data under the project folder.

Save HTML, CSS and JavaScript files to build a web server.

Create files to save small amounts of data instead of using a microSD card.

Create configuration files with settings.Using SPIFFS with the ESP32 board is specially useful to: SPIFFS doesn’t support directories, so everything is saved on a flat structure. You can read, write, close, and delete files. SPIFFS lets you access the flash memory like you would do in a normal filesystem in your computer, but simpler and more limited. SPIFFS is a lightweight filesystem created for microcontrollers with a flash chip, which are connected by SPI bus, like the ESP32 flash memory. The ESP32 contains a Serial Peripheral Interface Flash File System (SPIFFS). If you’re using Arduino IDE follow this tutorial instead: Install ESP32 Filesystem Uploader in Arduino IDE.
