2010-04-23 21:28:19     booting uclinux on BF561 problem

Hi all, recently I have succeeded booting uclinux on BF561-EXKIT, however, evert time I shut down the power I have to that process again. Is there any way that I can do it once and for all?

 

(I tried Nboot but BF561 seems does not support Nboot command)

 

Here is my process:

 

======================

 

bfin>loadb

 

******sending uImage******

 

bfin>bootm.

 

======================

 

If I let u-boot boot automatically, it would display "bad magic number" information.

 

Thanks for your patience.

SDRAM will not retain its contents by design.  if you want to keep it on the board, use parallel flash.
