Try loading your data at a higher address.  At the moment you're loading
your data only 4Kb beyond the default program start address (80090000).  An
alternative is to change the porgram address and load it beyond the data,
which will make sure you wont have to move your data as your program grows.
(Check out the linker settings for your CW project).

Strange.  Sounds like you're not setting up your OTs and packet areas
correctly.  Post us your source code and I'll take a look.  ( either here or
to my email: aherbert@ndirect.co.uk )
