Re: [linuxdc-dev] Question about bootstrapping. . .

[Matt G. <mg...@cm...>]

I've got this same problem right now.  I upgraded to the latest
toolchain patches available at ftp.m17n.org, got linux-2.4.18
from a kernel mirror, got the linux-sh and linux-sh-dc trees from
their respective SF CVS servers, used treelink appropriately,
compiled my kernel and tried to boot it using dcload.  As soon as
the file loads and begins to execute, the DC reboots.  To be
clear, no kernel startup messages appear to be printed before the
thing reboots.  Also, I was able to recompile and boot the kernel
source I got from Gatliff's article with my upgraded toolchain
just not 2.4.18-sh-dc.  Any suggestions?  

fyi, I'm 'inflex' on #dclinux.
