Re: help with inittab

The init is from Busybox. Since I'm getting output from my serial port
during the kernel boot process, I think it's safe to say that my
/dev/ttyS0 is properly configured. Besides passing the kernel argument
console=ttyS0,57600, is there anything else I need to do to properly
configure the console? I've looked through my kernel configuration to
make sure that any serial device or console related stuff was enabled
and configured.

I'm feeling pretty stumped.

Ok.. so if you are using the init from Busybox, there should be a
softlink and I can't remember where they put it.  I think it is the
root file system.  I think they call in linuxrc or something like
that.  I'd make sure you have that.

**OR** what I did..

Get sysinit from GNU and tell Busybox not to use the init.  I've had
this exact same problem and it was my init.

I've now determined that my kernel seems to stop in the following line
of code, in the function init(void * unused), in init/main.c:
run_init_process("/sbin/init");

Who's init are  you using??

Are you using Busyboxes or sysinit from GNU?

I've determined that it stops at this call by stepping through the code
with a BDI2000.

My boot arguments are:
console=ttyS0,57600n8 ip=off root=/dev/ram0 rw

My current inittab is:
::sysinit:/etc/rc.sh
::ctrlaltdel:/sbin/reboot
::shutdown:/sbin/swapoff -a
::shutdown:/bin/umount -a -r
::restart:/sbin/init
::respawn:/bin/sh

I've tried adding an "echo" command to the /etc/rc.sh script that is
called, but I don't see any output. I've also trying changing the
::sysinit line in inittab to point to some non-existent script, to see
if I'll get some error message, but I still see nothing. Is it possible
that /sbin/init is dying before it gets to the point of reading inittab?
Any ideas?

Regards,
Chris Dumoulin

And  what's  your  console  device?  Are  you  passing  any  console=
