You're right about it being hard to find! It's in a file called
At91LibV214_light.exe, but you can't find that file with a search at
Atmel's site. You have to drill down into a lot of pages to find it.
It comes with a lot of other programs so a lot of people don't even
know its there.

To recapfrom my earlier message, Angel is a serial monitor that gives
you access to RDI style commands through the Angel Debug Protocol
(ADP). Angel is not an ideal way to debug because of the serial port
connection, but there's a lot of interesting code in Angel for people
who want to write their own debugger.

For convenience of people who want the Angel monitor source code, I
pulled it out of that big file and posted it on my site:

http://www.ericengler.com/AngelMonitorSrc.zip

To go along with this, you need to get these documents. The first 2
are easy to find at the ARM website:
ADP_ARM_DUI0052C.pdf
ADP_ARM_DUI0053D.pdf

This page is good and it has links to the PDF files:
http://www.arm.com/products/DevTools/AngelDebugMonitor.html

One of the best references on Angel is a chapter in the ARM Software
Development Toolkit, version 2.11. The version is important because
the newest versions of this document do NOT have the Angel material!
The document code for this is ARM DUI 0041B. A slightly older version
of the same document has the same info. (I think its the same): ARM
DUI 0040C. If anyone can find a good download link for this document
please post it here! I'd put it on my site, but it's almost 10
megabytes and it could cost me a lot if many people download it (I pay
for the amount of bytes people download).

Lastly, the Angel Porting Guide:
