下載 Busybox
 

$ wget https://busybox.net/downloads/busybox-1.24.1.tar.bz2
...
$ tar jxvf busybox-1.24.1.tar.bz2
...

Busybox defconfig
 

首先你會需要一個 rk3066 專屬的 busybox defconfig 如下: 請將它拷貝至 busybox-1.24.1/configs/rk3066_defconfig .

Cross 編譯 Busybox
 

$ make ARCH=arm V=1 CROSS_COMPILE=arm-linux-gnueabihf- -C busybox-1.24.1 rk3066_defconfig

$ sudo make ARCH=arm V=1 CROSS_COMPILE=arm-linux-gnueabihf- -C busybox-1.24.1 clean

$ sudo make ARCH=arm V=1 CROSS_COMPILE=arm-linux-gnueabihf- -C busybox-1.24.1 install

現在在 _install 底下已經有了 bin, sbin, usr 資料夾了.

製作 Boot.img
 

在這兒我使用 unpacked-boot 做為 boot filesystem 的工作資料夾. 我們還需要幾個資料夾: 

etc/ , var/run/ , sys/ , usr/share/udhcpc/

jasonc@bebop:~/rk30-linux$ ls -l unpacked-boot/etc/
total 16
-rw-r--r-- 1 root root  26 11月 22 13:03 host.conf
-rw-r--r-- 1 root root  17 11月 22 13:03 hostname
-rw-r--r-- 1 root root 237 11月 22 13:03 hosts
-rw-r--r-- 1 root root   0 11月 21 17:40 mtab
-rw-r--r-- 1 root root 265 11月 21 19:19 resolv.conf
jasonc@bebop:~/rk30-linux$
jasonc@bebop:~/rk30-linux$ ls -l unpacked-boot/usr/share/udhcpc/
total 4
-rwxrwxrwx 1 root root 1293 11月 22 10:40 default.script
jasonc@bebop:~/rk30-linux$

etc/hostname 我們用 echo 產生: 

echo marsboard-rk3066 > unpacked-boot/etc/hostname

etc/host.conf , etc/hosts 以及 etc/resolv.conf 拷貝自 Host-Linux

#!/bin/bash -e

ROOTFSDEV=\`cat /proc/cmdline | busybox awk -F "root=" '{print \$2}' | busybox awk '{print \$1}'\`
mount \$ROOTFSDEV /mnt

cd unpacked-boot
sudo find . | cpio -o -H newc | gzip > ../boot-new.img
cd $TOP
sudo rkcrc -k boot-new.img boot.img
sudo /bin/rm -rf boot-new.img

執行上述這個 shell, 就可以產生 boot.img 了. 

Nfs 掛載 Rootfs
 

現在我嘗試著修改 unpacked-boot/init 這個檔案 . 增加了 NFS 掛載 ROOTFS 如下: 

#!/bin/sh

/bin/mount proc /proc -t proc
/bin/mount sysfs /sys -t sysfs
/bin/mount none /debug -t debugfs

mdev -s
if [ -f /usr/share/udhcpc/default.script ]; then
        sleep 1
        #udhcpc -i eth0 -t 1 -T 3 -s /usr/share/udhcpc/default.script
        udhcpc -i eth0 &
        sleep 6 && killall udhcpc
fi
mount -t nfs -o nolock,tcp 192.168.3.35:/home/jasonc/rk30-linux/unpacked-rootfs /mnt
if [ $? -ne 0 ]; then
        ROOTFSDEV=`cat /proc/cmdline | busybox awk -F "root=" '{print $2}' | busybox awk '{print $1}'`
        mount $ROOTFSDEV /mnt
fi
exec switch_root /mnt /sbin/init

Host-Linux Nfs 伺服器端 之設定 `/etc/exports` 內容如下: 

jasonc@bebop:~/rk30-linux$ cat /etc/exports
/home/jasonc/rk30-linux/unpacked-rootfs  *(rw,sync,no_root_squash,no_subtree_check)
jasonc@bebop:~/rk30-linux$

jasonc@bebop:~/rk30-linux$ sudo /etc/init.d/nfs-kernel-server restart
 * Stopping NFS kernel daemon                            [ OK ]
 * Unexporting directories for NFS kernel daemon...      [ OK ]
 * Exporting directories for NFS kernel daemon...        [ OK ]
 * Starting NFS kernel daemon                            [ OK ]
jasonc@bebop:~/rk30-linux$

現在 rootfs 掛載至 192.168.3.35:/home/jasonc/rk30-linux/unpacked-rootfs .

執行結果如下:

Kernel panic: Failed to execute /init (error -2)

在執行 busybox 過程中, 如果你遇到 kernel panic: Failed to execute /init (error -2) .... 這樣的訊息, error -2 是 no such file 的意思, 請 enable `Build BusyBox as a static binary`  這個選項. 我已經在前述的 defconfig 已經幫您 enable 了.
