Before you can debug your application, you must install the required software:

1. Install the cross-platform gdb with the following command:

   sudo apt-get install gdb-arm-none-eabi

   If there is a conflict with the previous gdb, remove the old gdb first using the sudo apt-get remove gdb command, and only install gdb-arm-none-eabi.

2. Install the dependable modules with the following command:

   sudo apt-get install gperf libncurses5-dev flex bison

To debug the application:

1. Set the needed break points by clicking the left side of the Code Editor:

   

2. In the Project Explorer view, select the project.
3. To debug the project, use one of the following:
   • In the Tizen Studio for RT menu, select Run > Debug As > Run to TizenRT Debugger.
   • In the Tizen Studio for RT toolbar, click the Debug icon () drop-down list, and select Debug As > Run to TizenRT Debugger.
   • Right-click the project in the Project Explorer view, and select Debug As > Run to TizenRT Debugger.

   

4. In the Select GDB Client Binary dialog box select the path where arm gdb is installed, and click OK:
   
   Note gdb installation path can be found using the command which arm-none-eabi -gdb in terminal.

   

5. Before the debugging starts, the Confirm Perspective Switch dialog box is shown. Click No, and add Source Mapping before proceeding to debug perspective:
   

   

6. To add Source Mapping, click Debug Configurations in the debug drop-down list:
   

   

7. Expand the GDB OpenOCD Debugging from the list in the left, and select the available configuration. Select the Source tab, and click Add:
   

   

8. Select Path Mapping option from the Add Source dialog box:
   

   

9. In the Path Mapping dialog click Add, and enter the name for new path mapping:
   • In the Configuration Path, add /root/tizenrt as path.
   • In the Local file system path, select the path where the TizenRT platform code is present.

   

   

   

10. Click OK after the TizenRT platform code has been selected:
    

    

    After, you have added the path mapping, you can see the new path mapping entry in source tab:

    

    After path mapping has been added, click Debug to start debugging.

    Confirm Perspective dialog box is shown, to switch to the Debug perspective, click Yes:

    

    The Debug perspective shows the views useful for debugging activities, organized in the optimal fashion within the Tizen Studio window:

    

    When an action is executed on the board and it passes through a break point, the line is in the suspended state (see the figure above):

    You can perform various debugging functions (such as resume, step into, and step over) by using the toolbar in the Debug perspective:
