It is not garbage data, it is GDB-stubs. Most probably, something goes wrong during startup, before reaching the redboot prompt, a processor exception is raised and caught by GDB-stubs which are now waiting for input from GDB.
If you get this far, a whole lot of things are already working: your serial communication seems ok, interrupts / exceptions are dealt with properly, your memory map most probably is ok.
