[linuxsh-dev] test5 kernel image problem

[Sathish V. <sv...@so...>]

Hello,

I seem to have a serious problem with the kernel I image
built...This is all I get and then silence.
---------------
Linux version 2.4.0-test5 (satish@posix) (gcc version 2.95.2 
19991024 (release)) #1 Wed Sep 6 15:05:45 IST 2000
On node 0 totalpages: 8192
zone(0): 8192 pages.
zone(1): 0 pages.
zone(2): 0 pages.
Kernel command line: mem=32M sh_mv=SolutionEngine console=ttySC1,115200
CPU clock: 80.00MHz
Bus clock: 20.00MHz
Module clock: 20.00MHz
Interval = 50000
------------------

It is true that my ramdisk does not include a 'linuxrc'
or 'init' but atleast I expected the ramdisk to load.

Is this a serial console problem ? Should I apply the
sci patches mentioned in the linuxsh-dev mailing list ?

Or is it due to the fact that cpu is 7709 and not 7709A ?

Thank you for any pointers

My environment:
    MS7709SE01 target board (note : cpu is SH7709, not 7709A )

This is how I built the ram disk:

mkdir rootfs
mkdir rootfs/dev
mknod rootfs/dev/ttySC0 c 204 8
mknod rootfs/dev/ttySC1 c 204 9
ln -s rootfs/dev/ttySC1 rootfs/dev/console
mkdir rootfs/lib
(cd $SH_INSTALL/sh-linux-gnu/lib ; tar cf - *.so*) | \
                          (cd rootfs/lib ; tar xf -)
mkdir rootfs/{proc,sbin,bin,usr,etc} rootfs/usr/{bin,sbin}
dd if=/dev/zero of=/dev/ram0 bs=1k count=4096
/sbin/mke2fs -F -vm0  /dev/ram0 4096
mkdir /tmp/fs
mount  /dev/ram0 /tmp/fs
(cd rootfs ; tar cf - .) | (cd /tmp/fs ; tar xvf -)
umount /tmp/fs
dd if=/dev/ram0 of=/var/tmp/initrd.img
cat /var/tmp/initrd.img | gzip -c > initrd.img
sh-linux-gnu-objcopy -I binary -O elf32-shl initrd.img \
          initrd.elf --adjust-vma=0x8c360000
