    12 <concept id="GUID-26714A57-B6B4-5E81-B512-FB520718482B" xml:lang="en"><title>Debug Monitor

    13 Tool</title><shortdesc>Describes how to get basic information about the system state when

    14 problems occur on hardware to help you debug your software.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

    15 <p>Device drivers are typically run and debugged on target hardware rather

    16 than on the Emulator. The tool that provides this information is called the <i>debug

    17 monitor</i> or the <i>crash debugger</i>. </p>

    18 <p>The debug monitor is used when the Kernel faults. This can happen because

    19 there is a fault in a kernel-side component, such as a device driver, or because

    20 a thread or process marked as system-critical crashes. </p>

    21 <p>Note that the debug monitor is one of the basic ways of debugging software

    22 problems on target hardware. Full interactive debugging on reference hardware

    23 and some real phones is available through commercial IDEs. </p>
