Debugging prerequisites
CE debug environment
Debug architecture
Debugging tools available to you
Demonstration
Advanced debugging tools
Visual Studio 2005 +
Platform Builder
Debug transport
Source code
Your device
Visual Studio: the IDE
Platform Builder: a Visual Studio plug-in
Using them, you can:
Build
Download to device
Debug
CE debugger affects
Entire OS
Applications Kernel
While debugger is loaded, the OS is
In run state In halted stateOr
Normal app debugging: separate VS2005 or load over debug transport
Connects device & host debuggers
KITL: Kernel Independent Transport Layer
Software layer connecting device to host
Supports:
Debugger
Command Shell
Remote Tools
Etc.
KITL active even when these tools aren’t!

Debugger extension
Automatically discovers:Stack overflows, thread starvation, deadlocks, orphaned synchronization objects,
heap corruption
Passive KITL
http://msdn.microsoft.com/en-us/library/aa914894.aspx
Don’t load KITL until an exception occurs
Great for beta testing
Hardware-assisted debugging
http://msdn.microsoft.com/en-us/library/aa935824.aspx
Using eXDI (eXtended Debug Interface)
For when KITL is unavailable:Bootloader, early OS boot, ISRs
Postmortem debugging
http://msdn.microsoft.com/en-us/library/aa936043.aspx
Can capture dump file during halted state
Debug later without the device
Visual Studio + Platform Builder
CE debugger = system debugger
Debug transport: KITL
Tons of debugging tools available to you
