</propre> Where <code>/temphome/root/Test </code> is the path in which your application will be dowloaded downloaded inside the device . [[File:QtCreator-4.4.1_project-Test-MainWindow-TestPro.png|1200px|border|center]] Build the project in order to complete the configuration and set the overall vars: [[File:QtCreator-4.4.1_project-Test-MainWindow-Build.png|1200px|border|center]] The last step before running the application inside the device is to configure Qt backend into application command line arguments: open the <code>Project</code> window and select the <code>Run</code> configuration, then type <code>-platform eglfs</code> into <code>Arguments</code> [[File:QtCreator-4.4.1_project-Test-MainWindow-eglfs.png|1200px|border|center]] After these changes you are ready to debug your application inside your board with the <code>Run/Debug</code> command [[File:QtCreator XELK 3 0 0 1935.png|30px]] [[File:QtCreator-4.4.1_project-Test-MainWindow-debug.png|1200px|border|center]] The debugger (via <code>gdb server</code>) will be activated and the debug window will be ready: [[File:QtCreator-4.4.1_project-Test-MainWindow-debug-running.png|200px1200px|leftborder|alt textcenter]]
