Hi,
I am working on G.729 in BF535 EZ-KIT. I have written the assembly code for convolution
function. I enabled optimization in Project Option. If i run the code, i got Unknown exception
occured and code is exit.  If optimization is disabled, code working without error. Can anybody
tell me where is the problem.
Also i am running the code with default .ldf file. I am not familiar in writing ldf.  I am also
used example ldf which was given by ADI. If i run with example ldf file i got error. So if
anybody having ldf please send it to me.

Usually that's an initialization problem.  Go thru your code and set all
variables to zero (or some constant) with explicit lines of code.  Most
likely it's an uninitialized pointer.

Definitly read the manual on that.  It takes a little while, but it is
worth it in the long run.

As an initial step on getting familiar with .ldf files take a look at the ADI online
training modules located at:

http://www.analog.com/processors/blackfin/onlineTrainingModules.html

Particularly the  "Basics of Building a Blackfin® Application" module gives a nice
overview about .ldf files.
