Hi,

I try to compile my own kernel for my Indy.
I got the sources from cvs yesterday and made 

 make config
 make dep
 make clean
 make vmlinux

It compiles fine but it will not boot. I get the following message:

>> boot vmlinux

I used the Indy running Linux 2.1.121 from ftp.linux.sgi.com/pub/test
and egcs-1.0.2 from hardhat and also my i586 with the crosscompiler
from ftp.linux.sgi.com with the same results.
The vmlinux-indy-2.1.121.tar.gz boots fine.

What am I doing wrong?

 Matthias

This is usually because you didn't remove the "-N" in arch/mips/Makefile
or similiar. It's in the FAQ, but I keep forgetting that myself.

My problem is when I build the kernel, I get nothing at all.  I get the
first line, something like:

115360+19600+3136+334528+42744d+4248+6368 entry: 0x89fa8840                                                                           

then a blank line, then a total hang, mouse and keybaord included.

So can we detect the bad versions of binutils and automatically set the
LDFLAGS correctly?  I'm tired of forgetting. =)

Thank you. That helped. I read about this a few weeks ago but since I was
far away from compiling a kernel back then I did not remember it.

Looks like the console output is going to a serial line. Can you connect
over the network.
I do not have a keyboard, mouse and monitor. I get the console output to
the serial line.
Right now I get the output to my terminal but I can't get a login prompt.
However I can connect over the network.

 Matthias
