Dear Wolfgang Denk,
I tried the uboot version 2010.12 also with the eldk but I didn't get it
running.
Here is my patch. It seems there is a problem in the lolevel_init. But I
didn't flound it. At the moment I have no debugger.
So I have two problems the version 2010.12 didn't work with eldk and the
version 2010.09 works with eldk but not with gcc 4.5.2.
How can I found these problems?
Best regards / Mit freundlichen Grüßen
Maik Hänig

In message<4d4fc86c.2080...@hrz.tu-chemnitz.de> you wrote:
should I better use gcc 4.4?
No, you should go forward, i. e. rather use current U-Boot code that
is supposed to fix these problems (at last the most obvious ones - and
if there are any left, you'd help to detec and eventually fix these,
too).
And yes I'm working on ARM.
Thought so from the symptoms you reported...
Best regards,
Wolfgang Denk
