    I re-examined the Platform Design and I found the error. I had assumed the new modules were hooked up to System Console's Avalon port. They were not. "deadc0de" is the output from the default slave. I attempted a search of the code to find it originally, but it was hidden and I did not find it. Thank you for the direction.

Definitely need more information here, like what the system design looks like, maybe code of your custom component, etc. If you are addressing a non-existent address space in a Platform Designer system, there is a "default agent" set to respond, so it could be that. You don't mention what address you are trying to access.

Really just need more details.
