クロス開発環境†

binutilsとgccを開発マシンにインストールします。

# rpm -i binutils-sh4-2.13.90.0.18-1.i686.rpm 
# rpm -i gcc-sh4-3.2.3-2.i686.rpm

ライブラリはignorearchを忘れずに。

# rpm -i --force --ignorearch glibc-devel-sh4-2.3.1-3u.sh4.rpm

rootfs†

# mkdir /tftpboot/rootfs

rpmの中身を確認

# rpm -qpl /tmp/hoge.rpm

展開

# rpm2cpio /tmp/hoge.rpm | cpio -id

Kernel†

netboot用の設定をパクります。

# cp arch/sh/def-configs/r2d_nfs.config .config

menuconfigでは何もしないで終了。

# make ARCH=sh menuconfig

build。

# make ARCH=sh dep clean zImage

インストール？

cp arch/sh/boot/zImage /tftpboot

シリアルコンソール†

Baud rate115200
Data8bit
Paritynone
Stop1 bit
Flow controlnone

FreeBSDの場合

cu -s 115200 -l cuaa0

とします。

Linuxの場合

# minicom -s

A -    Serial Device      : /dev/ttyS0
B - Lockfile Location     : /var/lock
C -   Callin Program      :
D -  Callout Program      :
E -    Bps/Par/Bits       : 115200 8N1
F - Hardware Flow Control : No
G - Software Flow Control : No

と設定します。

# minicom

r2dの電源を投入するとこうなります。

nで起動するはずです。

とりあえずシリアルコンソールからloginします。

sshのrsaとdsaのhost keyが自動生成されないので手動で生成します。

# /usr/bin/ssh-keygen  -q -t dsa -f /etc/ssh/ssh_host_dsa_key -C '' -N ''
# chmod 600 /etc/ssh/ssh_host_dsa_key
# chmod 644 /etc/ssh/ssh_host_dsa_key.pub

sshdを起動して，適当にuserを追加すると

hasebe@sm501:~% slogin r2d
hasebe@r2d's password:

BusyBox v0.60.5 (2004.01.18-15:25+0000) Built-in shell (ash)
Enter 'help' for a list of built-in commands.

~ $

ぉぉぉ。sloginできます。ただしlogin shellとして/bin/tcshはないのでご注意を。

↑

コンパクトフラッシュ起動†

↑

Kernel†

当然ながらこのままではnetbootしてしまうので修正します。

↑

CF†

Redhat9の場合，USB接続のCF-RWはSCSIデバイスとして認識されます。

# fdisk /dev/sda

とりあえず問答無用でd
次にn, p, 1, Enter, +768M
最後にn, p, 2, Enter, Enter
おっと，スワップだったt, 2, 82

で，こうなりました。

   Device Boot    Start       End    Blocks   Id  System
/dev/sda1             1      1091    750607+  83  Linux
/dev/sda2          1092      1454    249744   82  Linux swap

a, 1してブータブルにします。
wで書き込み。割と時間がかかりますねえ。

newfs，もとい，mkfsします。

# mkfs -t ext2 /dev/sda1

スワップも作ります。

# mkswap /dev/sda2

インストールメディアをマウント

# mount -t ext2 /dev/sda1 /mnt
↑

sh-lilo†

解凍してMakefile

CROSS_COMPILE= sh4-linux-

と修正

なんかprecompiled/boot.bがありますが，気にせずmake。

# cp boot.b /mnt/boot/

クロス用lilo.conf

linear
# Cross LILO
# Actually, it's /dev/hda
boot = /dev/sda
disk = /dev/sda
  bios=0x80
#
delay = 30
vga = normal
image = /boot/zImage
        label = linux
        root = /dev/hda1
        read-only

ちなみに，boot, diskのデバイスは開発マシンから見たCF。

sdaがない場合は

# cp -a /dev/sda /mnt/dev

CFのMBRにloaderを書き込みます。
-rを忘れるとエロいことになります。

# lilo -r /mnt
Added linux *

こうなればOKです。

fstabを修正しなきゃ。 /etc/fstab

#/dev/root /     nfs  defaults 0 0
/dev/hda1 /     ext2 defaults 0 0
proc      /proc proc defaults 0 0
