Then the answer to your question is simple: you made some  errors  in
your  port  of U-Boot to your hardware. I know, this is just an anwer
to your question, not a solution to your problem.

You are wrong. A LOT of the  configuration  parameters  are  hardware

Basicly anything. Bad clock configuration for example.

GUIs  are  virtually  useless.  Learn  tools.  They're  configurable,
scriptable, automatable, cron-able, interoperable, etc. We don't need
no brain-dead winslurping monolithic claptrap.
