结果中能看到如下信息
Linux version 4.4.16 (gcc version 4.9.4 (Linaro GCC 4.9-2017.01) )
### 编译ramdisk(busybox-1.22.0)
修改busybox源码中的xconnect.c解决ping bad addr bug
[参考文章](http://hankjin.blog.163.com/blog/static/337319372009327101324432/)
设置交叉编译工具和安装路径等(参考rk3399_busybox_defconfig)
Build BusyBox as a static binary (no shared libs)
可以在.config中直接设置
CONFIG_PREFIX="/home/zeroway/rk3399/bsp/ramdiskfs"
CONFIG_CROSS_COMPILER_PREFIX="/home/zeroway/rk3399/tool/gcc-linaro-4.9.4-2017.01-i686_aarch64-linux-gnu/bin/aarch64-linux-gnu-"
编译安装
make
make install
经过上一步已经将busybox安装到ramdiskfs文件夹中,有如下内容(linuxrc是指向busybox的链接)
bin linuxrc sbin usr
继续在ramdiskfs目录中创建必要的目录结构
mkdir var tmp sys root proc opt mnt lib home etc dev
再在etc下创建一个init.d的目录用于保存一些初始化的脚本
mkdir etc/init.d
touch etc/init.d/rcS
rcS脚本如下
mount -a
mkdir /dev/pts
mount -t devpts devpts /dev/pts
echo /sbin/mdev > /proc/sys/kernel/hotplug
/sbin/mdev -s
给rcS脚本添加可执行权限
chmod +x etc/init.d/rcS
创建sysconfig
mkdir etc/sysconfig
echo "rk3399" > etc/sysconfig/HOSTNAME
添加/etc/fstab内容如下
proc /proc proc defaults 0 0
tmpfs /tmp tmpfs defaults 0 0
sysfs /sys sysfs defaults 0 0
tmpfs /dev tmpfs defaults 0 0
添加必要的设备节点
sudo mknod dev/console c 5 1
sudo mknod dev/null c 1 3
添加/etc/inittab内容如下
::sysinit:/etc/init.d/rcS
console::askfirst:-/bin/sh
::ctrlaltdel:/sbin/reboot
::shutdown:/bin/umount -a -r
添加/etc/profile内容如下
ulimit -S -c 0 > /dev/null 2>&1
USER="`id -un`"
LOGNAME=$USER
PS1='[\u@\h \W]\# '
PATH=$PATH:/usr/local/bin
HOSTNAME=`/bin/hostname`
export USER LOGNAME PS1 PATH
添加/etc/passwd内容如下
root:x:0:0:root:/:/bin/sh
ftp::14:50:FTP User:/var/ftp:
bin:*:1:1:bin:/bin:
daemon:*:2:2:daemon:/sbin:
nobody:*:99:99:Nobody:/:

修改[cmdline](./cmdline_linux)参数如下(主要修改init=/linuxrc)
CMDLINE: androidboot.baseband=N/A androidboot.selinux=disabled androidboot.hardware=rk30board androidboot.console=ttyFIQ0 init=/linuxrc mtdparts=rk29xxnand:0x00002000@0x00002000(uboot),0x00002000@0x00004000(trust),0x00002000@0x00006000(misc),0x00008000@0x00008000(resource),0x0000A000@0x00010000(kernel),0x00010000@0x0001A000(boot),0x00010000@0x0002A000(recovery),0x00038000@0x0003A000(backup),0x00040000@0x00072000(cache),0x00200000@0x000B2000(system),0x00008000@0x002B2000(metadata),0x00002000@0x002BA000(baseparamer),-@0x002BC000(userdata)
制作一个大小位8M的ext2格式镜像文件,并挂载到/mnt/initrd目录下
拷贝ramdiskfs里所有文件到/mnt/initrd下
dd if=/dev/zero of=initrd.img bs=1k count=8192
sudo mkfs.ext2 -F initrd.img
sudo mkdir /mnt/initrd
sudo mount -t ext2 -o loop initrd.img /mnt/initrd
sudo cp -rfvd ramdiskfs/* /mnt/initrd
sudo umount /mnt/initrd
gzip --best -c initrd.img > ramdisk.img
sudo chmod 777 ramdisk.img
使用RK提供的打包工具将ramdisk打包成boot
rkst/mkkrnlimg ramdisk.img boot.img
烧写ramdisk镜像
rkflashtool w boot < boot.img
上网设置(配置网卡,设置域名服务和默认网关)
ifconfig eth0 192.168.1.234 up
echo "nameserver 192.168.1.1" > /etc/resolv.conf
route add default gw 192.168.1.1
