---+ Installing ppc64 Fedora Core 8 on PASemi "Electra" Board

%TOC%

---++ 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

<verbatim>
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
</verbatim>

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:
<verbatim>
# 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
</verbatim>


Partition use in both install stages:

   * Auxiliary ELDK hard disk install:
<verbatim>
/       ext3    /dev/sda2
        swap    /dev/sda5
</verbatim>

   * Final Fedora Core hard disk install:
<verbatim>
/       ext3    /dev/sda3
/boot   ext2    /dev/sda1
        swap    /dev/sda5
</verbatim>


Note 2: If necessary create required hard disk =/dev/*= entries, e.g.:
<verbatim>
# mknod /dev/sda b 8 0
# mknod /dev/sda1 b 8 1
# mknod /dev/sda2 b 8 2
etc.
</verbatim>

---++ Step 3 - Reboot to CFE firmware and start system with ELDK root fs from hard drive

<verbatim>
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
</verbatim>

Note 3: Create /etc/resolv.conf
<verbatim>
# cat /etc/resolv.conf
nameserver 192.168.1.254
domain denx.de
</verbatim>

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:

<verbatim>
# 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
</verbatim>

---+++ 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:

<verbatim>
MIRROR=ftp://ftp.stw-bonn.de/pub/fedora/linux/releases/8/Everything/ppc/os/Packages
</verbatim>

   * use =wget ${MIRROR}/package_name= command to download a package
   * and =rpm= command to install it

<verbatim>
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 gdbm-1.8.0-27.fc7.ppc.rpm
rpm -ivh keyutils-libs-1.2-2.fc6.ppc.rpm
rpm -ivh glib2-2.14.2-1.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 openssl-0.9.8b-17.fc8.ppc.rpm
rpm -ivh --nodeps krb5-libs-1.6.2-9.fc8.ppc.rpm
rpm -ivh keyutils-libs-devel-1.2-2.fc6.ppc.rpm 
rpm -ivh libsepol-devel-2.0.11-1.fc8.ppc.rpm 
rpm -ivh libselinux-devel-2.0.37-1.fc8.ppc.rpm 
rpm -ivh --nodeps e2fsprogs-libs-1.40.2-10.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
</verbatim>


At this point =yum= should be correctly installed:

<verbatim>
# yum --version
3.2.7
</verbatim>


---++ Step 5 - Preparations for the proper Fedora Core installation:


---+++ Mount install partitions

<verbatim>
# 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
</verbatim>


---+++ Initialize RPM database on your target file system

<verbatim>
# cd /mnt/fc
# mkdir -p var/log var/lib/rpm
# mkdir -p var/lib/yum
# rpm --root=/mnt/fc --initdb
</verbatim>


---+++ Install the "fedora-release-*" RPMs

<verbatim>
wget ${MIRROR}/fedora-release-*.noarch.rpm
rpm --root=/mnt/fc -ivh --nodeps fedora-release-*.noarch.rpm
</verbatim>


---+++ Edit =yum= repository configurations

<verbatim>
# cd /mnt/fc/etc/yum.repos.d
</verbatim>

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
<verbatim>
# cd /etc/pam.d
# cp ftp ftp.orig
# cp passwd ftp
</verbatim>
on nfs server:
<verbatim>
$ cd /path/to/the/kenrel/image/dir/
$ ftp electra
ftp> cd /
ftp> bin
ftp> put vmlinux
</verbatim>


---+++ Other setup

<verbatim>
# mount -t proc none /mnt/fc/proc/
# ln -s /mnt/fc/etc/pki/rpm-gpg/ /etc/pki/
</verbatim>


---++ Step 6 - Fedora Core installation


Use the =yum= tool to perform a full installation of the "Base" system

<verbatim>
# yum --installroot=/mnt/fc -y groupinstall Base
</verbatim>

Make sure =yum= selects ppc64 packages:

<verbatim>
=============================================================================
 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
...
</verbatim>



---++ 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).

<verbatim>
# rm -rf /mnt/fc/dev
# cp -a /dev /mnt/fc/
</verbatim>

---+++ Create =/etc/fstab=

<verbatim>
# 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
</verbatim>


---+++ Network setup

<verbatim>
# cp /etc/resolv.conf /mnt/fc/etc/
# cp /etc/sysconfig/network /mnt/fc/etc/sysconfig/
</verbatim>

---+++ Copy kernel image

<verbatim>
# cp /vmlinux /mnt/fc/boot/vmlinux
</verbatim>


---+++ Set root password on a new system

<verbatim>
# chroot /mnt '/usr/bin/passwd'
</verbatim>



---++ Step 8 - Boot newly installed Fedora Core

<verbatim>
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
</verbatim>
