Just a couple hints that may be useful for your next

If you didn't already know, you can type halt in the
BDI console when you are in a running state and get
whatever is running (e.g., U-Boot) suspended. This 
is handy when you are looking
at lots of debug output in the U-Boot console (you'll
get there ;-)

Also, you can attach gdb through the BDI if you don't
have an extra serial port (you can set up kgdb through
U-Boot via a second serial interface). This has been
real handy for me.

Glad to see you've gotten this far! Continued good
