Installing ppc64 Fedora Core 8 on PASemi "Electra" Board
Abstract
This Application Note describes how to install the ppc64 version of
Fedora Core 8 (Werewolf) Linux distribution on the PASemi
"Electra"
Board.
The installation process is a two stage operation. First stage involves booting
target board with the
ELDK root file system mounted over the NFS and installing
a copy of the
ELDK root file system to the local hard disk.
Second stage starts from booting installed
ELDK root file system from the local
hard disk and installing from there Fedora Core 8 on another partition of the
same local hard disk.

Installation Requirements
In order to install Fedora Core 8 on the Electra board you need the following
hardware and software components:
- a target PASemi Electra board with a S-ATA hard disk attached and a network connection.
- a ELDK (4.2, ppc64) root file system mountable over NFS.
Step 1 - Build linux kernel and boot with the ELDK root fs over NFS
CFE> setenv -p nfs-eldk "ifconfig eth1 -auto; setenv bootargs 'debug root=nfs rw
nfsroot=192.168.1.3:/opt/eldk-ppc64/ppc64 ip=192.168.230.2:192.168.1.1::255.255.0.0:electra:eth1:';
boot -elf 192.168.1.1:/tftpboot/electra/vmlinux"
CFE> nfs-eldk
Note 1: If no RTC support is present, set correct date manually
Step 2 - Install the ELDK copy on the local hard disk
For detailed instructions see:
http://www.denx.de/wiki/view/DULG/ELDKInstallationOnLocalHarddisk
Harddisk partition layout used in this howto:
# fdisk -l /dev/sda
Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 250 2008093+ 83 Linux
/dev/sda2 251 3986 30009420 83 Linux
/dev/sda3 3987 7722 30009420 83 Linux
/dev/sda4 7723 14593 55191307+ 5 Extended
/dev/sda5 7723 7972 2008093+ 82 Linux swap / Solaris
/dev/sda6 7973 10405 19543041 83 Linux
/dev/sda7 10406 14593 33640078+ 83 Linux
Partition use in both install stages:
- Auxiliary ELDK hard disk install:
/ ext3 /dev/sda2
swap /dev/sda5
- Final Fedora Core hard disk install:
/ ext3 /dev/sda3
/boot ext2 /dev/sda1
swap /dev/sda5
Note 2: If necessary create required hard disk
/dev/* entries, e.g.:
# mknod /dev/sda b 8 0
# mknod /dev/sda1 b 8 1
# mknod /dev/sda2 b 8 2
etc.
Step 3 - Reboot to CFE firmware and start system with ELDK root fs from hard drive
CFE> setenv -p hd-eldk "ifconfig eth1 -auto; setenv bootargs 'debug root=/dev/sda2 ro ip=192.168.230.2:192.168.1.1:192.168.1.254:255.255.0.0:electra:eth1:off';
boot -elf 192.168.1.1:/tftpboot/electra/vmlinux"
CFE> hd-eldk
Note 3: Create /etc/resolv.conf
# cat /etc/resolv.conf
nameserver 192.168.1.254
domain denx.de
See also Note 1 and Note 2.
Step 4 - Install Fedora yum on top of a ELDK installation
Select Fedora mirror
Choose the nearest mirror from
http://mirrors.fedoraproject.org/publiclist/Fedora/8/
Install wget package
Select .ppc64.rpm version of wget package as it will work on top of
ELDK
without any further dependency resolution:
# ftp ftp.stw-bonn.de
ftp> cd /pub/fedora/linux/releases/8/Everything/ppc64/os/Packages/
ftp> bin
ftp> get wget-1.10.2-16.fc8.ppc64.rpm
ftp> bye
# rpm -ivh --nodeps --ignorearch wget-1.10.2-16.fc8.ppc64.rpm
Install yum and its dependencies:
To avoid conflicts with the ELKD package set (ppc64), yum and its dependencies
are installed in the form of the
ppc binaries:
MIRROR=ftp://ftp.stw-bonn.de/pub/fedora/linux/releases/8/Everything/ppc/os/Packages
- use
wget ${MIRROR}/package_name command to download a package
- and
rpm command to install it
rpm -ivh libgcc-4.1.2-33.ppc.rpm
rpm -ivh --nodeps glibc-2.7-2.ppc.rpm
rpm -ivh elfutils-libelf-0.130-3.fc8.ppc.rpm

rpm -ivh --nodeps libxml2-2.6.30-1.ppc.rpm
rpm -ivh popt-1.12-3.fc8.ppc.rpm

rpm -ivh --nodeps e2fsprogs-devel-1.40.2-10.fc8.ppc.rpm
rpm -ivh --nodeps krb5-devel-1.6.2-9.fc8.ppc.rpm
rpm -ivh --nodeps python-libs-2.5.1-15.fc8.ppc.rpm python-2.5.1-15.fc8.ppc.rpm
rpm -ivh python-iniparse-0.2.2-1.fc8.noarch.rpm
rpm -ivh python-urlgrabber-3.0.0-3.fc8.noarch.rpm
rpm -ivh libselinux-python-2.0.37-1.fc8.ppc.rpm
rpm -ivh rpm-libs-4.4.2.2-3.fc8.ppc.rpm rpm-4.4.2.2-3.fc8.ppc.rpm
rpm -ivh rpm-python-4.4.2.2-3.fc8.ppc.rpm
rpm -ivh yum-metadata-parser-1.1.2-1.fc8.ppc.rpm
rpm -ivh yum-3.2.7-1.fc8.noarch.rpm
At this point
yum should be correctly installed:
# yum --version
3.2.7
Step 5 - Preparations for the proper Fedora Core installation:
Mount install partitions
# mkdir /mnt/fc
# mkefs -j /dev/sda3
# mount /dev/sda3 /mnt/fc
# mkdir /mnt/fc/boot
# mkefs /dev/sda1
# mount /dev/sda1 /mnt/fc/boot
Initialize RPM database on your target file system
# cd /mnt/fc
# mkdir -p var/log var/lib/rpm
# mkdir -p var/lib/yum
# rpm --root=/mnt/fc --initdb
Install the "fedora-release-*" RPMs
wget ${MIRROR}/fedora-release-*.noarch.rpm
rpm --root=/mnt/fc -ivh --nodeps fedora-release-*.noarch.rpm
Edit yum repository configurations
# cd /mnt/fc/etc/yum.repos.d
Edit all
.repo files, replace
$basearch with
ppc64 string to force
installation for ppc64 architecture (otherwise
$basearch would select
tools (yum, etc.) architecture, which is
ppc).
Copy kernel image from nfs location to the hard disk
on electra, enable password ftp login
# cd /etc/pam.d
# cp ftp ftp.orig
# cp passwd ftp
on nfs server:
$ cd /path/to/the/kenrel/image/dir/
$ ftp electra
ftp> cd /
ftp> bin
ftp> put vmlinux
Other setup
# mount -t proc none /mnt/fc/proc/
# ln -s /mnt/fc/etc/pki/rpm-gpg/ /etc/pki/
Step 6 - Fedora Core installation
Use the
yum tool to perform a full installation of the "Base" system
# yum --installroot=/mnt/fc -y groupinstall Base
Make sure
yum selects ppc64 packages:
=============================================================================
Package Arch Version Repository Size
=============================================================================
Installing:
anacron ppc64 2.3-57.fc8 updates 42 k
attr ppc64 2.4.38-2.fc8 updates 63 k
authconfig ppc64 5.3.18-1.fc8 fedora 408 k
autofs ppc64 1:5.0.2-24 updates 1.0 M
bind-utils ppc64 32:9.5.0-22.b1.fc8 updates 212 k
...
Step 7 - Minimal post install configuration
The following additional actions are necessary to get a booting system:
Create /dev/* entries
Populate
/dev directory in new file system with the minimum of entries
(for example, copy
/dev from running system; this is a overkill, but
simple enough).
# rm -rf /mnt/fc/dev
# cp -a /dev /mnt/fc/
Create /etc/fstab
# cp /etc/fstab /mnt/fc/etc
# vi /mnt/fc/etc/fstab
# cat /mnt/fc/etc/fstab
/dev/sda3 / ext3 defaults 1 1
/dev/sda1 /boot ext2 defaults 1 2
/dev/sda5 swap swap defaults 0 0
none /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
Network setup
# cp /etc/resolv.conf /mnt/fc/etc/
# cp /etc/sysconfig/network /mnt/fc/etc/sysconfig/
Copy kernel image
# cp /vmlinux /mnt/fc/boot/vmlinux
Set root password on a new system
# chroot /mnt '/usr/bin/passwd'
Step 8 - Boot newly installed Fedora Core
CFE> setenv -p hd-fc "setenv bootargs 'debug root=/dev/sda3 ro ip=192.168.230.2:192.168.1.1:192.168.1.254:255.255.0.0:electra:eth1:off'; boot -fs=ext2 sata0.0:/vmlinux
CFE> hd-fc
