Platformio in Vs Code Failed to Upload Code to Stm32f103c8t6

Acquire how to upload files to the ESP32 lath filesystem (SPIFFS) using VS Code with the PlatformIO IDE extension (quick and easy). Using the filesystem with the ESP32 can be useful to save HTML, CSS and JavaScript files to build a web server instead of having to write everything within the Arduino sketch.

If you're using Arduino IDE follow this tutorial instead: Install ESP32 Filesystem Uploader in Arduino IDE.

Introducing SPIFFS

The ESP32 contains a Serial Peripheral Interface Wink File Organization (SPIFFS). SPIFFS is a lightweight filesystem created for microcontrollers with a wink chip, which are connected by SPI bus, similar the ESP32 wink memory.

SPIFFS lets you lot access the flash memory similar you lot would practise in a normal filesystem in your computer, just simpler and more limited. Y'all tin can read, write, close, and delete files. SPIFFS doesn't support directories, so everything is saved on a apartment structure.

Using SPIFFS with the ESP32 board is specially useful to:

• Create configuration files with settings;
• Save information permanently;
• Create files to relieve small amounts of data instead of using a microSD carte;
• Salve HTML, CSS and JavaScript files to build a web server;
• Salve images, figures and icons;
• And much more.

Upload Files to ESP32 SPIFFS

The files you want to upload to the ESP32 filesystem should exist placed in a folder chosen information under the project folder. For y'all to understand how everything works, we'll upload a .txt file with some random text. You can upload whatsoever other file blazon.

If you're not familiar with VS Code + PlatformIO, follow the next tutorial first:

• Getting Started with VS Lawmaking and PlatformIO IDE for ESP32 and ESP8266

Creating a data Folder

Create a folder called data inside your project folder. This tin exist done on VS Code.
With your mouse, select the projection binder you're working on. Click on the New Binder icon to create a new folder.

This new folder must exist called data, otherwise, information technology won't work.

So, select the newly created data binder and create the files you desire to upload by clicking on the New File icon. In this instance, we'll create a file chosen text.txt. Yous can create and upload any other file types like .html, .css or .js files, for example.

Write some random text inside that .txt file.

The information binder should be under the project folder and the files you want to upload should be within the information folder. Otherwise, information technology won't work.

Uploading Filesystem Prototype

After creating and saving the file or files you want to upload under the data folder, follow the adjacent steps:

1. Click the PIO icon at the left side bar. The project tasks should open.
2. Select env:esp32doit-devkit-v1 (it may be slightly different depending on the board you're using).
3. Aggrandize the Platform carte du jour.
4. Select Build Filesystem Image.
5. Finally, click Upload Filesystem Image.

Important: to upload the filesystem image successfully y'all must close all series
connections (Serial Monitor) with your lath.

Later a while, you should get a success bulletin.

Troubleshooting

Here's some mutual mistakes:

Could non open port "COMX" Access is denied.

This error means that yous have a series connexion opened with your board in VS Code or in any other program. Close any program that might be using the board serial port, and make sure you close all serial connections in VS Code (click on the recycle bin icon on the terminal console).

Timed out waiting for packet header error

If you starting time seeing a lot of dots on the debugging window and the filesystem paradigm fails to upload, yous demand to printing the on-board boot button once y'all start seeing the dots.

To solve this result permanently, read the following article:

• [SOLVED] Failed to connect to ESP32: Timed out waiting for packet header

Testing

Now, permit'southward just check if the file was really saved into the ESP32 filesystem. Copy the following code to the main.cpp file and upload information technology to your board.

          /*********   Rui Santos   Complete project details at https://RandomNerdTutorials.com/esp32-vs-lawmaking-platformio-spiffs/   *********/  #include <Arduino.h> #include "SPIFFS.h"   void setup() {   Serial.brainstorm(9600);      if(!SPIFFS.brainstorm(true)){     Series.println("An Error has occurred while mounting SPIFFS");     render;   }      File file = SPIFFS.open up("/text.txt");   if(!file){     Serial.println("Failed to open file for reading");     render;   }      Serial.println("File Content:");   while(file.available()){     Serial.write(file.read());   }   file.shut(); }   void loop() {  }                  

View raw code

You may need to change the following line depending on the name of your file.

          File file = SPIFFS.open("/text.txt");        

Open the Serial Monitor and it should print the content of your file.

Y'all've successfully uploaded files to the ESP32 filesystem (SPIFFS) using VS Code + PlatformIO.

Wrapping Up

With this tutorial yous've learned how to upload files to the ESP32 filesystem (SPIFFS) using VS Code + PlatformIO. It is quick and like shooting fish in a barrel.

This can be specially useful to upload HTML, CSS and JavaScript files to build web server projects with the ESP32 boards.
