+debugging</title>       <p>Device Driver debugging is similar to kernel-mode
+debugging, as drivers run as part of the Kernel. Debug versions of the drivers
+can be debugged using debug tools such as Lauterbach through a JTAG interface
+or an IDE. Other debug tools such as Metro TRK can also be used. </p> <p>Most
+of the hardware platforms supported by Symbian platform are ICE-enabled. Kernel
+developers and those porting the operating system to new hardware often have
+access to development boards exposing the JTAG interface, which allows the
+use of CPU-level debuggers. Using a host PC debugger, such as Carbide.c++
+or CodeWarrior configured for remote debugging, a debug ROM image (including
+drivers) can be downloaded to the target and debugged over a JTAG interface. </p> <p>For
+debugging, debug versions drivers are built, and the ROM image is built to
+include the kernel debug DLL, which enables kernel-side (stop mode) debugging.
+This is done by using the <codeph>STOP_MODE_DEBUGGING</codeph> flag while
+building the ROM image. For example: </p> <p><userinput>rom –v=h4hrp –I=armv5
+–define=STOP_MODE_DEBUGGING</userinput> </p> <p>This includes the kernel extension <filepath>kdebug.dll</filepath> in
+the ROM image, which provides a stop mode debugger API. </p> <p>When the ROM
+image is downloaded to the target, the system boots up and the Kernel or driver
+can be debugged using the host based IDE interface. Code can be stepped through
+and halted, and memory on the target can be viewed. </p> <p>Symbian also provide
+a debug monitor (sometimes called the crash debugger) to provide information
+on Kernel crashes. See <xref href="GUID-26714A57-B6B4-5E81-B512-FB520718482B.dita">Debug
+Monitor Tool</xref> for more details. </p>     </section>
