First let’s install necessary packages on host platform. Execute as root user:

Code: Select all: apt-get install tftpd-hpa nfs-kernel-server apache2

Let’s make public directory for root file system and kernel.

Code: Select all: mkdir -p /var/www/pub/9302 cd /var/www/pub/9302

Extract root file system

Code: Select all: tar -jxvf /angstrom/build/tmp-angstrom_2008_1/deploy/glibc/images/cs-e9302/Angstrom-minimal-osgi-glibc-ipk-2011.03-cs-e9302.rootfs.tar.bz2

We are going to create virtual host for accessing local binary repository from target platform. So edit file

Code: Select all: nano /etc/apache2/sites-available/default

and add the following in the of file

Code: Select all: <VirtualHost *:8080> ServerAdmin webmaster@localhost DocumentRoot /angstrom/build/tmp-angstrom_2008_1/ <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /angstrom/build/tmp-angstrom_2008_1/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /doc/ "/usr/share/doc/" <Directory "/usr/share/doc/"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order deny,allow Deny from all Allow from 127.0.0.0/255.0.0.0 ::1/128 </Directory> </VirtualHost>

Now restart apache

Code: Select all: /etc/init.d/apache2 restart

We have to make some modifications in target rootfs

Code: Select all: nano /var/www/pub/9302/etc/network/interfaces

and make eth0 with static configuration

Code: Select all: # Wired or wireless interfaces auto eth0 #iface eth0 inet dhcp #iface eth1 inet dhcp iface eth0 inet static address 192.168.1.200 netmask 255.255.255.0 network 192.168.1.0 gateway 192.168.1.1

In this case IP address of target platform will be 192.168.1.200
Also edit /var/www/pub/9302/etc/resolv.conf to point to local DNS.

Next step is to configure feed links in target platform
NOTE:IP address of host platform is 192.168.1.155

Edit file

Code: Select all: nano /var/www/pub/9302/etc/opkg/base-feed.conf

and change feed location from

Code: Select all: src/gz base http://feeds.angstrom-distribution.org/feeds/unstable/ipk/glibc/armv4t/base

to

Code: Select all: src/gz base http://192.168.1.155:8080/deploy/glibc/ipk/armv4t

Edit file

Code: Select all: nano /var/www/pub/9302/etc/opkg/cs-e9302-feed.conf

and change feed location from

Code: Select all: src/gz cs-e9302 http://feeds.angstrom-distribution.org/feeds/unstable/ipk/glibc/armv4t/machine/cs-e9302

to

Code: Select all: src/gz cs-e9302 http://192.168.1.155:8080/deploy/glibc/ipk/cs-e9302

Edit file

Code: Select all: nano /var/www/pub/9302/etc/opkg/noarch-feed.conf

and change feed location from

Code: Select all: src/gz no-arch http://feeds.angstrom-distribution.org/feeds/unstable/ipk/glibc/all

to

Code: Select all: src/gz no-arch http://192.168.1.155:8080/deploy/glibc/ipk/all

For NFS server configuration edit file

Code: Select all: nano /etc/exports

and the following in the end of file

Code: Select all: /var/www/pub 192.168.1.0/24(rw,nohide,no_root_squash,insecure,no_subtree_check,async)

For TFTP server configuration edit file

Code: Select all: nano /etc/default/tftpd-hpa

and the change the line

Code: Select all: TFTP_DIRECTORY="/var/lib/tftpboot"

with this one

Code: Select all: TFTP_DIRECTORY="/var/www/pub"

Restart NFS and TFTP servers

Code: Select all: /etc/init.d/tftpd-hpa restart /etc/init.d/nfs-kernel-server restart

Final step is to run our target platform. Connect RS232_0 serial port of development board to PC with baud rate of 57600. You can use any software for serial communication like PuTTY or SercureCRT(in Windows). Turn on power supply. Press CTRL + C. Use the following Redboot options:

Code: Select all: RedBoot> fconfig -l Run script at boot: true Boot script: .. load -v -r -b 0x80000 -h 192.168.1.155 -m http /pub/9302/boot/zImage .. exec -c "root=/dev/nfs nfsroot=192.168.1.155:/var/www/pub/9302 ip=192.168.1.200:192.168.1.1:255.255.255.0 console=ttyAM0,57600n8" Boot script timeout (1000ms resolution): 5 Use BOOTP for network configuration: false Gateway IP address: 192.168.1.1 Local IP address: 192.168.1.200 Local IP address mask: 255.255.255.0 Default server IP address: 192.168.1.1 DNS server IP address: 192.168.1.1 Set eth0 network hardware address [MAC]: true eth0 network hardware address [MAC]: 0x00:0x00:0x00:0x00:0x54:0x33 GDB connection port: 9000 Force console for special debug messages: false Network debug at boot time: false RedBoot>

In configuration options above linux kernel is loading from host platform through HTTP. In case of using TFTP you should use

Code: Select all: load -v -r -b 0x80000 9302/boot/zImage

Root file system could be loaded from USB flash disk too. Please follow the instructions bellow in order to setup root file system on USB disk.

Code: Select all: mkfs -t ext2 -b 1024 -m 0 /dev/sdb

Let’s turn off checks for problems with file system

Code: Select all: tune2fs -c 0 -i 0 /dev/sdb

Mount the disk

Code: Select all: mount /dev/sdb /mount

Copy file system

Code: Select all: cp -R /var/www/pub/9302/* /mount

Unmount the disk

Code: Select all: umount /dev/sdb

Redboot option to load root file system from USB flash disk is

Code: Select all: exec -c "console=ttyAM0 root=/dev/sda1 rootdelay=6"

Example of successful boot
