Hard to tell from your description.  Can you provide more infomation:  What is your flash and DRAM capacity?  Do you have license to upgrade from IP Base to, say, IP Services?

I have 32k bytes of config memory and 16

k of flash memory.

I also have a smartnet contract which should provide for IOS upgrade I think
