What initialization does your BDM debugger do that your start up code 
does not do?

I don't know what BDM you are using and am not very familiar with the 
4xx family, but Best Practices is to create a minimal BDM config and use 
that, especially when things work with the BDM plugged in but not when 
running bare.

If that doesn't help, git bisect.
