Kernel woes for versions > 2.2.5

Kernel woes for versions > 2.2.5

[Grant Carter]

Hi all

I have successfully compiled the 2.2.5 kernel which is found on the ftp
site for my BSE-IP board. Now that that seems to work, I would like to
get a newer version of the kernel working. I have tried unsucessfully
with both the 2.3.18 kernel on the CVS server and the tarball of it that
Dan put up for ftp. The problem is that after the kernel has been loaded
into RAM at address 200000 and told to execute from address 210000, the
processor just hangs with no output on the console. It doesn't even get
to the "Linux/PPC load:" prompt. The process I just described was what I
was told to do for 2.2.5 and it works just great. Is there a different
method for the other kernel versions? Any ideas on where to go from
here?

Many thanks in advance,
Grant

Take a look at arch/ppc/mbxboot/embed_config.c.  At the end
of this is the function for initializing the board information
structure.  Make sure you use the same information from the
kernel that is booting correctly, in particular assigning the
proper processor speed.  I have discussed this with Stuart of
BrightStar Engineering, and I haven't yet included a processor
speed variable in the environment variables.  The default
configuration is not correct for this processor, so you have
to assign the proper values here.  I am likely to have missed
this when making the last kernel update.
