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
