Basic configuration guide for Embedded Linux development using IntelliJ IDEA

Introduction:
IntelliJ IDEA is a powerful integrated development environment (IDE) that can be used when developing embedded Linux projects. Provides convenient coding, debugging and deployment tools. This article will introduce how to perform basic configuration of Embedded Linux development in IntelliJ IDEA.

Step 1: Install IntelliJ IDEA
First, you need to download and install IntelliJ IDEA from the official website (https://www.jetbrains.com/idea/). The installation process is relatively simple, just follow the wizard prompts.

Step 2: Configure JDK
IntelliJ IDEA requires Java Development Kit (JDK). Make sure you have the appropriate version of the JDK installed and configured correctly.

1. In IntelliJ IDEA, click "File"->"Project Structure" in the menu bar to open the project structure window.
2. Select "SDKs" in the left panel and click the " " button in the upper right corner.
3. Select "JDK" in the pop-up window.
4. Browse and select the configured JDK path.
5. Click "OK" to save changes.

Step 3: Create a new project
Next, you need to create a new project and configure it accordingly.

1. In the welcome interface of IntelliJ IDEA, click "Create New Project".
2. Select "Project"->"Empty Project" in the pop-up window and click "Next".
3. Enter the project name and save path, and click "Finish" to create a new project.

Step 4: Import the project source code
If you already have the existing Embedded Linux project source code, you can import it directly. If not, you can skip this step.

1. In IntelliJ IDEA, click "File"->"New"->"Module from Existing Sources" in the menu bar.
2. Browse and select the project source code path in the pop-up window.
3. Click "Next".
4. Follow the wizard prompts to configure and import the project source code.

Step 5: Configure the project SDK and tool chain
In Embedded Linux development, the project's SDK and tool chain (Toolchain) are very important. You need to configure IntelliJ IDEA to recognize and use them correctly.

1. In IntelliJ IDEA, click "File"->"Project Structure" in the menu bar to open the project structure window.
2. Select "Modules" in the left panel and select the project module.
3. Select "Dependencies" in the right panel.
4. Click the " " button in the upper right corner and select "JARs or directories".
5. Browse and select the path to the SDK and tool chain.
6. Click "OK" to save changes.

Step 6: Configure remote debugging
Embedded Linux development often requires remote debugging. IntelliJ IDEA provides powerful remote debugging functions to facilitate your debugging and analysis.

1. In IntelliJ IDEA, click "Run"->"Edit Configurations" in the menu bar to open the configuration window.
2. Click the " " button in the upper left corner and select "Remote".
3. Enter the configuration name and port number, and click "OK".
4. Enter the IP address of the target device in the "Host" field.
5. Enter the debug port number of the target device in the "Port" field.
6. Ensure that the corresponding debugging server has been started on the target device.
7. Click "OK" to save changes.
8. Set breakpoints in the code and click the "Debug" button to start remote debugging.

Code example:

public class HelloWorld {

public static void main(String[] args) {
    System.out.println("Hello, World!");
}

}

Conclusion:
By following the above steps to configure, you now Embedded Linux development is already possible in IntelliJ IDEA.
