Hi Boaz

What version of CodeWarrior are you using? I think it was version 5.0.2 or
5.0.3 that had problems with pragma interrupt, at least if you checked
"deferred inlining" under Language Settings under Target settings. The
absence of an RTI at the end of an ISR would make very strange things
happen.

If I'm right, you should not be using pragma interrupt with the SDK. The
SDK does the saving and restoring, and the RTI. You function is just a user
callback function when you use the SDK.

Could you possibly have more code than really fits in your program RAM?
Does the same thing happen if you cut out most of your app code and just run
interrupts?

I also like to do the following when weird things happen: create a new
project in a new directory. Drag in the code files needed. Don't check
many checkboxes - start with "factory defaults". Don't optimize. Is the
problem still there? If not, check only those checkboxes you really need.
Apparently the project files just "get corrupted" occasionally.

Conceivably you could re-make the libraries like MSL C 56800.lib and
FP56800.lib. That is needed if you upgrade your IDE. There is a project
somewhere that will automate that for you.

You might test whether the strange things only happen while you are
debugging with breakpoints. I occasionally have strange things happen if I
put a breakpoint on a line like "if (fubar == 0)".

I like to remove all object code periodically. I also Purge debug cache
anytime things get strange (Edit | Preferences | Debugger | Purge Cache.

If I have more than one copy of a source file anywhere in a directory tree
that CodeWarrior ever heard about, I check the properties of the source file
in my Project source tree window, to make sure the file I am editing is the
same one the compiler is compiling.

Good luck!

Software is loosing it.... Hello,
Without interrupts, sw is running ok.
When I apply the interrupts (archEnableInt), the sw is doing crazy
stuff - some of the data is overrun, code sections are executed even
though it is not supposed to.
But, the sw is alive, doing other things it is supposed to!!
It behaves as if some code lines are ignored!

I check the stack: STACK IS OK. (I filled end-of stack with known
data, and checked it - it was not overrun -> no stack overflow) -
thanks for the suggestion.

I'll appriciate more ideas and suggestions. :-)
