In the following, a short step-by-step tutorial how to get up and running with CoIDE and J-Link in general is given. For this tutorial, the sample project generator that is integrated into CoIDE was used.

• Start CoIDE and click New Project button from the status bar.
• Enter a Project Name and click Finish
  
• Select the manufacturer of the eval board, the project shall be created for.
  We used ST in this example.
  
• Select the appropriate core, for example STM32F103ZG.
• Select the components which should be used. In this example we used GPIO.
• Click GPIO in the Components tab / window.
• A new tab with example projects appears. Click on add in order to add a sample project, for example GPIO_Blink.
• In order to add the selected example to the project click Yes.
  
• Click on the Build button.
  
• In order to modify J-Link specific settings click the Debug Configuration button.
  A new dialog will show up. (See sample configuration for J-Link below)
• Click Apply in order to confirm settings.
• Click Close.

Now you are ready to go
