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.

Hth,

English usage hint:

It's usual to use "Dear" along with a name as a saluation in a
formal letter.  For example:

   Dear Mr. Edwards
  
   Thank you for your interest in our product line.  Blah,
   blah, blah...

However, using "dear" alone when addressing a person is used to
express intimacy or affection (you call your husband or wife
wife or very close friend/relative "dear").

> I got ur message..

Oh, and the words you were looking for were "Thanks" and
"your".  ;)

	By the way, I'm not native english, but a lot of people here says "Oh!
Dear..." when u got in a bad situation like, for example,  Redboot not
working... :-)

Good point.  I hadn't thought about that third usage, where
you're not addressing or saluting[1] anybody.

[1] "Saluting" sounds very odd in this context, but isn't that
     what you're doing when you're using a salutation?
