First I would like to point out (like many times before) that  U-Boot
related  questions  are  off-topic  on  a  linuxppc-dev mailing list.
Please post such questions to the u-boot-users list.

One of my teachers used to say that some people only  learn  when  it
hurts really bad.

I hope you understand that you should have  investigates  _why_  yuou
could  not  copy your image to flash. Thi is supposed to work, and if
it fails it usually means that you made  something  wrong.  Analyzing
the  error  and  understanding _what_ you did wrong is very important
for you to avoid the same error in the future.

Well, and "erasing a few sectors randomly" is such a bad idea that  I
better keep my mouth shut.

Probably you overwrote more than you think.

Restart from scratch: erase the _whole_  flash  memory,  and  install
_only_ U-Boot. Then power-cycle the board. Then check again.


And never ever erase "random sectors" again.
