Debugging the Project

Note

Tizen RT IDE has been deprecated since Tizen Studio 4.1. This document is obsolete.

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:

    Setting break points

  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 (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:

    Debug perspectiveno

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

    Debug configurations

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

    Debug sourceadd

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

    Debug sourcepath

  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.

    Debug sourcepath

    Debug filepath

    Debug rtcodepath

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

    Debug filepathok

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

    Debug pathmapadded

    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:

    Perspective switch

    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:

Note

OpenOCD (or other remote debuggers) can only create as many debugger instances as there are connected devices. So, if you connect only one device, you cannot create two debugger instances.

When working with only one debugger instance, you must stop the previously running debugging operation to start a new debugging operation.

If you run more than one debugger at the same time, you get an error.
