本人在ubuntu 32位机上下载了Android4.0.1的源码，并make完成；
我使用2.3.1源码中的genrootfs.sh生成rootfs_dir文件夹；命令如下：
?#!/bin/sh
PRODUCT=generic
echo -n "Generating rootfs for Android..."
rm -fr rootfs_dir
cp -a out/target/product/${PRODUCT}/root/ rootfs_dir
cp -a out/target/product/${PRODUCT}/system/* rootfs_dir/system
cp -a out/target/product/${PRODUCT}/data/* rootfs_dir/data
chown root:root rootfs_dir -R
chmod 755 rootfs_dir/system/etc/dhcpcd/dhcpcd-run-hooks
chown 1014:2000 rootfs_dir/system/etc/dhcpcd/dhcpcd-hooks -R
chown 1000:1000 rootfs_dir/data -R
echo "...done"
#function mvapk()
#{
#mv $1 rootfs_dir/mnt/apps
#echo " $1"
#}
if [ "${PRODUCT}" = "generic" ]; then
echo -n "Create device file..."
mkdir rootfs_dir/dev/input
mknod rootfs_dir/dev/tty c 5 0
mknod rootfs_dir/dev/console c 5 1
mknod rootfs_dir/dev/fb0 c 29 0
mknod rootfs_dir/dev/pointercal c 10 119
mknod rootfs_dir/dev/input/event1 c 13 65
mknod rootfs_dir/dev/ts-if c 10 185
mknod rootfs_dir/dev/touchscreen c 10 180
mknod rootfs_dir/dev/touchscreen-1wire c 10 181
mknod rootfs_dir/dev/s3c2410_serial0 c 204 64
mknod rootfs_dir/dev/s3c2410_serial3 c 204 67
echo "...done"
echo -n "Install prebuilt packages..."
if [ -f vendor/samsung/common/busybox-bin.tgz ]; then
tar xf vendor/samsung/common/busybox-bin.tgz -C rootfs_dir/system
ln -sf /system/busybox/bin/busybox rootfs_dir/system/bin/sh
mkdir -p rootfs_dir/bin && ln -sf /system/busybox/bin/sh rootfs_dir/bin/sh
fi
if [ -f vendor/samsung/common/iwtools-bin.tgz ]; then
tar xf vendor/samsung/common/iwtools-bin.tgz -C rootfs_dir/system/bin
fi
echo "...done"
echo -n "Install kernel modules and firmware..."
if [ -f vendor/samsung/smdkv210/firmware.tgz ]; then
tar xf vendor/samsung/smdkv210/firmware.tgz -C rootfs_dir/system/etc
fi
if [ -f vendor/samsung/smdkv210/kernel-modules.tgz ]; then
tar xf vendor/samsung/smdkv210/kernel-modules.tgz -C rootfs_dir/system/lib
find rootfs_dir/system/lib/modules/ -name modules.* \
-o -name source -o -name build | xargs rm -rf
fi
echo "...done"
echo -n "Install proprietary-open files..."
[ -f FriendlyARMData.tgz ] && tar xf FriendlyARMData.tgz -C rootfs_dir
echo "...done"
#cp vendor/friendly-arm/mini210/rootdir/* rootfs_dir/ -af
# chown 1000:1000 rootfs_dir/data/app -R
# chmod 775 rootfs_dir/data/app
# chmod 664 rootfs_dir/data/app/*.apk
# chown 1000:1000 rootfs_dir/data/system -R
# chmod 775 rootfs_dir/data/system
find rootfs_dir/ -name CVS -type d | xargs rm -rf
fi
再用mkyaffs2image rootfs_dir rootfs_android4.0.1.img
将rootfs_android.4.0.1.img替换光盘Android内的rootfs_android-mlc2.img
修改FriendlyARM.ini文件
#This line cannot be removed. by FriendlyARM(

CheckOneButton=No
Action = Install
OS = Android
LowFormat = Yes
VerifyNandWrite = No
CheckCRC32=No
StatusType = Beeper | LED

使用SD模式启动Tiny210V2 开发板；
在烧写过程中出现：
Bad Yaffs Image file
通过超级终端输出的结果是：
