Data Abort, Prefetch Abort, PC=???

Question

Hello,

I am trying to find the source for the Data Abort exception, but no module is listed so I don't know where to look for the exception address.

In Bruce's blog http://geekswithblogs.net/BruceEitman/archive/2008/05/19/windows-ce--finding-the-cause-of-a-data-abort.aspx there is a reference to the makeimg output. What is this file?

So I have 3 questions:

Q1) What/Where to find Makeimg output? (is this one per module/dll?)

Q2) if PC does not explicitly show a module name, how can I find the aggresor?

Q3) Is there a compilation switch or command to insert the "module name" into the Data Abort output?

Answer 1

Hi,

How about looking at the Debug CallStack?

Answer 2

Since you have a Prefetch Abort first, you might find Windows CE: Prefetch Aborts, why they are difficult to locate  interesting.
