How to Debug a Windows CE 5.0 Debug Image

  • In progress

    • This application note will guide you through the steps needed, to create a debug image for Windows CE 5. This is demonstrated with a BSP for Trizeps IV, but the steps will almost also apply for Trizeps5, Trizeps2 and Trizeps3.

    Preparation

    Take a look at Building a Windows CE 5.0 Image for Trizeps4 from Scratch. This project will be used as starting point.

    Selecting Debug Configuration

    Every Platform-Builder-Workspace has two different configurations. The Release-configuration which you have used in the Building a Windows CE 5.0 Image for Trizeps4 from Scratch-application note and the Debug-configuration. In the Debug-configuration all modules are build with debugging-information. This and the fact that some optimizations are disabled increases the size of the output files.

    Select TR4CONXS_Debug.

    Building the Debug Image

    Run Build OS –> Sysgen.

    After several minutes you will see:

    Unlike the CoreMax-project, which can be easily built for Release and Debug, the Demo-project is far too big.
    To be able to build a debug-image, we can use a trick:

    1. Build OS –> Open Build Release Directory will show you where the _FLATRELEASEDIRECTORY resides.

    2. Change the name of this directory from TR4CONXS_ARMV4I_Debug to TR4CONXS_ARMV4I_FullDebug.

    3. Make a copy of the TR4CONXS_ARMV4I_Release directory and name it TR4CONXS_ARMV4I_Debug.

    4. Build OS –> Build Sysgen Current BSP.

    5. Copy desired debug-DLL's and EXE to the debug directory.

    6. Build OS –> Make Run-Time Image

    This time Make Run-Time Image will finish with success.

    Prepare SD-Card

    The easiest way to load a debug-image, is to use a SD-card. Put nk_ram.nb0 and a autoboot.bat with following contents onto the card:

    display boot mmc nk_ram.nb0 kitl

    display will show a boot-bitmap if one is stored on the Trizeps-module.
    boot mmc nk_ram.nb0 kitl will boot the image from SD-card and the command-line-argument kitl will tell the image to start the kitl-transport.

    Insert SD-card into the card-socket of your board.

    Start Debugging

    Now that you have a Windows CE5.0-Debug-Image, you can start to debug.
    Select Target –> Connectivity Options.

    Now set:

    1. Download to None.

    2. Transport to Ethernet.

    3. Debugger to KdStub.

     

    Press Settings-button next to the Transport-box and power-up your device.

    After some seconds a name will appear in the Active Devices-window. Select it and press OK. Close the Target Device Connectivity Options-dialog with Apply.
    If you have a serial-link connected to COM1 with 38K4 Baud 8N1, than you will see, that the device first tries to obtain an IP-address from a BOOTP-server and if that fails, it will get it's IP through DHCP.

    Press Target –> Attach Device.

    Now the kitl-debug-connection will be established and you may set breakpoints, use the Windows CE Shell-extension or other powerful debug tools of the Windows CE Platform Builder.
