[Kernel compile]

1: Download orignal linux2.6.32.2 tarball

2: enable uda1341, cs8900 driver, with following patches:

- in resource link

3: kernel config file

- in resouce link or:

- ARCH=arm make s3c2410_defconfig, be sure to enable ARM_EMBI config

[busybox compile]

with default configuration

[Creating ramdisk]

1:  dd if=/dev/zero of=./ramdisk bs=1k count=16384  //creating a 16MB ramdisk

2: sudo mke2fs -F -v -m0  ./ramdisk

3: sudo mount -o loop ./ramdisk  ramdisk_mnt/

4: copy busybox file to ramdisk

busybox$ sudo cp -ar _install/*  ramdisk_mnt/

5: copy necessary lib files to ramdisk

for file in libc libcrypt libdl libm libpthread libresolv libutil 
do 
cp $file-*.so /home/eric/temp/ 
cp -d $file.so.[*0-9] /home/eric/temp/ 
done 

cp -d ld*.so* /home/eric/temp/ 
  
cp libgcc_s.so* /home/eric/temp/ 

6: create fstab file

cat > etc/fstab << "EOF" 
# Begin /etc/fstab 
# file system  mount-point  type     options             dump  fsck 
#                                                              order 
 
#/dev/<xxx>     /            <fff>    defaults            1     1 
#/dev/<yyy>     swap         swap     pri=1               0     0 
proc           /proc        proc     nosuid,noexec,nodev 0     0 
sysfs          /sys         sysfs    nosuid,noexec,nodev 0     0 
devpts         /dev/pts     devpts   gid=4,mode=620      0     0 
tmpfs          /run         tmpfs    defaults            0     0 
devtmpfs       /dev         devtmpfs mode=0755,nosuid    0     0 
 
# End /etc/fstab 
EOF 

7: create rclocal file:

cat etc/init.d/rcS
#!/bin/sh

mount -t proc /proc

mount -t sys /sys

8: creat dev node:

mknod full c 1 7 
mknod kmem c 1 2 
mknod mem c 1 1 
mknod null c 1 3 
mknod port c 1 4 
mknod random c 1 8 
mknod urandom c 1 9 
mknod zero c 1 5 
for i in `seq 0 7`; do  
mknod loop$i b 7 $i 
done 
for i in `seq 0 9`; do 
mknod ram$i b 1 $i 
done 
ln -s ram1 ram 
mknod tty c 5 0 
for i in `seq 0 9`; do 
mknod tty$i c 4 $i 
done 
for i in `seq 0 9`; do 
mknod vcs$i c 7 $i 
mknod vcsa$i c 7 $[$i+128] 
done 
ln -s vcs0 vcs 
ln -s vcsa0 vcsa 
mknod -m 666 ttySAC0 c 204 64 
ln -s ttySAC0 console

9: umount ramdisk_mnt, and gzip ramdisk to generate the ramdisk.gz
