I know nothing about this processor or your architecture, or how it interacts with gdb, but sometimes this type of problem occurs when gdb and gdbserver disagree on the number of registers or their size of registers at the target. There can be many different sources of the problem, from mismatched gdb versions to poorly written gdb stubs, to miscompiled programs. Don't know if that will help, but that is where I would look.
