I assume that you're trying to load an eCos application, correct? Are you using a different configuration than what you used to build RedBoot? The most common error that can cause this type of behaviour is using GDB to actually load code onto memory that GDB &/or RedBoot use. If you provide a little more [detailed] information about your setup we may be able to help.
