Yup, same thing.

I used the above for a while. Obviously -- same startup spinner.
|/-\ :). 

Then decided I wanted this packaged in u-boot-tools.

Rewrote after after playing with various timings, moving to mmap(), 
kwbimage.h, adding term mode, etc.

It works pretty reliably for me. Let me know if not find sth. Especially
if see more than a couple '+' chars popping up during upload (I never
do, unless I deliberately scratch the TX line. Should propbably have
tested with a longer cable.).

Thanks,
Daniel
