希望大家在此帖把在学习2410过程中关于ARM Linux的一些笔记写/贴出来，也希望有兴趣的朋友积极参与。
作为开贴，我转几篇我在chinaunix的关于2410入门的blog

QT2410入门实践02 --- PC（宿主机）环境安装及配置
2007/10/21
===================================================================================================
Host OS install and environment build
===================================================================================================
1. Linux host OS: Ubuntu-7.10
2. On linux host, execute command after installed
$sudo apt-get upgrade
$sudo apt-get update
3. Install build-essential - this will install a complete devlopement environment for linux
$sudo apt-get install build-essential libncurses5-dev bison flex texinfo zlib1g-dev gettext autoconf
4. Install nfs
$sudo apt-get install nfs-kernel-server
$edit /etc/exports, add /opt/nfs *(sync,rw)
$sudo /etc/init.d/nfs-kernel-server restart
5. Install tftp
1) Install tftpd and related packages.
$sudo apt-get install xinetd tftpd tftp
2) Create /etc/xinetd.d/tftp and put this entry:
service tftp
{
protocol = udp
port = 69
socket_type = dgram
wait = yes
user = nobody
server = /usr/sbin/in.tftpd
server_args = /tftpboot
disable = no
}
3) Make /tftpboot directory
$sudo mkdir /tftpboot
$sudo chmod -R 777 /tftpboot
$sudo chown -R nobody /tftpboot
4) Start tftpd through xinetd
$sudo /etc/init.d/xinetd start

QT2410入门实践03 ---交叉编译工具（for ARM）及rootfs（for NFS）的制作
===================================================================================================
Building buildroot-20071126.tar.bz2
===================================================================================================
1. Untar buildroot package
$cd /opt
$sudo tar -jxvf buildroot-20071126.tar.bz2 -C ./
$cd /opt/buildroot
2. Modify configure files
1)inittab
$cd /opt/buildroot/target/generic/target_skeleton/etc/ //this inittab using udev
$modify initab and uncomment ttyS0 as following:
# Put a getty on the serial port
ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100
$cd /opt/buildroot/target/generic/target_skeleton/etc/init.d
$Add "/bin/sh" to rcS script at the end of file as following:
......
#add /bin/sh start
echo "QT2410 shell"
/bin/sh
#add /bin/sh end
$cd /opt/buildroot/target/generic/target_busybox_skeleton/etc //this inittab using mdev buildin busybox
$modify inittab and uncomment ttySo as following:
# Put a getty on the serial port
ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100
$cd /opt/buildroot/target/generic/target_busybox_skeleton/etc/init.d
$Add "/bin/sh" to rcS script at the end of file as following:
......
#add /bin/sh start
echo "QT2410 shell"
/bin/sh
#add /bin/sh end
3. Make menuconfig & make
$cd /opt/buildroot
$sudo make menuconfig (according to package versions as following list)
binutils-2.18.tar.bz2
busybox-1.7.2.tar.bz2
cramfs-1.1.tar.gz
fakeroot_1.8.2.tar.gz
gcc-4.2.1.tar.bz2
genext2fs-1.4.tar.gz
gmp-4.2.2.tar.bz2
jpegsrc.v6b.tar.gz
libpng-1.2.16.tar.bz2
linux-2.6.23.tar.bz2
lzo_1.08.orig.tar.gz
module-init-tools-3.2.2.tar.bz2
mpfr-2.3.0.patch
mpfr-2.3.0.tar.bz2
mtd_20061007.orig.tar.gz
ncurses-5.5.tar.gz
pkg-config-0.21.tar.gz
tslib-1.0.tar.bz2
uClibc-0.9.29.tar.bz2
udev-114.tar.bz2
zlib-1.2.3.tar.bz2
Note:1)MTD/JFFS2 utilities must use mtd_20061007.orig.tar.gz version
$sudo make WITHOUT_XATTR=1
4. Customizing busybox and uclibc for support NFS boot
$cd /opt/buildroot
$sudo make busybox-menuconfig
$Busybox Settings -> General configuration --> RPC support
$Busybox Settings -> Build Options -> Build BusBox as an static binary
$Linux System Utilities ->mount ->Support mounting NFS file system
$sudo cp project_build_arm/uclibc/busybox-1.7.2/.config package/busybox/busybox-1.6.0.config
$cd /opt/buildroot
$sudo make uclibc-menuconfig
$Networking support -> Remote Procedure Call (RPC) support
$cd /opt/buildroot
$sudo make WITHOUT_XATTR=1
5. Make device node for console
$cd /opt/buildroot/project_build_arm/uclibc/root/dev
$rm console -Rf
$sudo mknod -m 660 console c 5 1
# Need not make device node of null(Note!!!)
# $rm null -Rf
# $sudo mknod -m 660 null c 1 3
6. Modify init scipt （Note：Need not this modification if you have done step 2。1）
$cd /opt/buildroot/project_build_arm/uclibc/root/etc
$modify inittab and uncomment ttyS0 as following:
# Put a getty on the serial port
ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100
$cd buildroot/project_build_arm/uclibc/root/etc/init.d
$Add "/bin/sh" to rcS script at the end of file as following:
......
#add /bin/sh start
echo "QT2410 shell"
/bin/sh
#add /bin/sh end
7. Add cross toolchain to PATH environement（Host PC）
$Modify /etc/profile to add follow content at the end of file:
PATH=$PATH:/opt/buildroot/build_arm/staging_dir/usr/bin
export PATH
8. Done! That's all. ARM Linux cross toolchain and rootfs is completed until now!
9。/opt/buildroot/project_build_arm/uclibc/root/ is a completed rootfs for NFS。
