Compile kernel Image Get the file Patch Compile zImage

File you need go and downloadwww.intel.com  ipl_ixp400accesslibrarywithcrypto-1_5.zip  ipl_ixp400npelibrarywithcrypto-1_5.zip  ixp400linuxethernetdriverpatch-1_2.zip  ixp400linuxintegrationpatch-1_2.zip Unzip them to /root/nplab (work dir)

Patch the file Copy the file /opt/montavista/pro/devkit/lsp/adi- coyote-arm_xscale_be/linux _mvl31 linux Here has the source code of the kernel we need and then create a soft link “linux” point to the copy directory

Patch the file Fix ixp400_xscale_sw/buildUtils/environment.linux.sh  linuxbe_KERNEL_DIR=/root/nplab/linux  IX_XSCALE_SW=/root/nplab/ixp400_xscale_sw execute. environment.linux.sh

Patch the file Go to /root/nplab/linux  patch -p1 <../ixp400LinuxKernel-BE-1_2.patch  patch -p1 <../ixp400LinuxEthernetDriver-1_2.patch Go to /root/nplab  Use ixp425_eth_update_nf_bridge- 1_2.patch to fix ixp425_eth.c

Start to compile zImage Go to /root/nplab/linux “make menuconfig”  System Type ->IXP425 Implementation Options  Network device support->Ethernet (10 or 100Mbit)  Intel IXP425 Ethernet Device support

Start to compile zImage After “make menuconfig”,edit “.config” ， patch Accesslibary CONFIG_IXP425_LIB=m make dep make zImage

Complete the compile We will have the “zImage” at /root/nplab/linux/arch/arm/boot Copy zImage to /tftpboot

Set up Target Configure moinicom Edit Script

Configure minicom Logon Linux by root “Minicom –s” to configure minicom

Configure minicom configure serial port by below

Configure minicom Exit Serial port setup and enter Modem and dialing

Configure minicom Clean A 、 B 、 K fields

Configure minicom Save setup as df1 Select “exit” to exit and connect to target Or select “exit from minicom” to exit

Edit Script Restart target. Press Ctrl+C to redboot

Edit Script At RedBoot Command line ， enter “fconfig” to edit Script and network

Edit Script zImage 檔名

Edit Script Set Script waiting time before execute （ for example, wait 3 seconds ）

Edit Script Set up your network

Edit Script Save and restart

Set up Server TFTP server DHCP server NFS server

Set up TFTP server Edit /etc/xinetd.d/tftp Change the “disable” field from “yes” to “no”

Set up TFTP server After save the file, execute etc/init.d/xinetd reload zImage will be copied to /tftpboot

Set up DHCP server Check dhcp.leases If not, use “touch”

Set up DHCP server Edit /etc/dhcp.conf

Set up DHCP server Restart DHCP server Run DHCP server when boot

Set up NFS server Edit /etc/exports Add “/opt/montavista/pro/devkit/arm/xscale_be/target *(rw,no_root_squash,no_all_squash)” Restart NFS

Set up NFS server Run NFS server when boot /sbin/chkconfig nfs on Sync NFS daemon ： /usr/sbin/exportfs -ra

Hello world Set up executable search path Compile a program

The executable search path of Target 提供 Host 端使用 MontaVista™ Linux® 工具 Application ： /opt/montavista/host/bin Man Pages ： /opt/montavista/host/man Info Pages ： /opt/montavista/host/info

The executable search path of host 提供 Host 端開發並可以在 Target 端執行的程 式 Application ： /opt/montavista/devkit/arm/xscale_be/bin Man Pages ： /opt/montavista/devkit/arm/xscale_be/ma n Info Pages ： /opt/montavista/devkit/arm/xscale_be/inf o

The executable search path of Cross-development Application ： /montavista/devkit/arm/xscale_be/target/bin  Target ： /bin /opt/montavista/devkit/arm/xscale_be/target/usr/bin  Target ： /usr/bin /opt/montavista/devkit/arm/xscale_be/target/sbin  Target ： /sbin /opt/montavista/devkit/arm/xscale_be/target/usr/sbin  Target ： /sbin /opt/montavista/devkit/arm/xscale_be/target/usr/share  Target ： /usr/share Man Pages ： /opt/montavista/devkit/arm/xscale_be/target/usr/share/man Info Pages ： /opt/montavista/devkit/arm/xscale_be/target/usr/share/info

Set up executable search path of Target 、 Host and Cross-development Set up Host Application path ： /opt/montavista/pro/host/bin PATH=$PATH:/opt/montavista/pro/host/bin Then we can use the tool MontaVista™ Linux® provide （ ex. mvl-rpm ） montavista

Set up executable search path of Target 、 Host and Cross-development Set up Application path of Cross development ： /opt/montavista/pro/devkit/arm/xscale_be/bin PATH=$PATH:/opt/montavista/pro/devkit/arm /xscale_be/bin Cross development Application perfix ： xscale_be- （ ex. xscale_be-gcc ） montavista

Set up executable search path of Target 、 Host and Cross-development Edit /etc/profile Add Host Application path: /opt/montavista/pro/host/bin Add Cross development application path ： /opt/montavista/pro/devkit/arm/xscale_be/bin

Hello world Create a directory “myapplication” Edit a progream : hellow.c

Hello world Use xscale_be-gcc to compile your c file Copy it to the directory where target mount /opt/montavista/pro/devkit/arm/xscale_be /target/root/

Execute the binary on target Logon on target and execute

Kernel module Create kernel module Install NPE-Ethernet driver

Create kernel module First, check the environment Go to /root/nplab and then use ”make module” to create kernel module

Create kernel module Execute make modules_install INSTALL_MOD_PATH=/~~~~ Install modules to the directory where target mount

Install NPE-Ethernet driver module Logon on target and use “lsmod” to show what modules have been loaded use “rmmod” to remove the module

Install NPE-Ethernet driver module Go to /lib/modules/2.4.20_mvl31- coyote/kernel/drivers/ixp400/

Install NPE-Ethernet driver module Ismod ixp400.o Go to /lib/modules/2.4.18_mvl30-ixdp425/kernel/drivers/net Ismod ixp425_eth.o
