开发要求
- radxa rock (全版或者简版)
- 64bit Linux (e.g. Ubuntu) 开发环境
- micro USB 数据线
- 5V/2A的电源
Install the toolchain
下载交叉编译工具链
64bit 主机
git clone -b kitkat-release --depth 1 https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6
或者从这里下载
http://dl.radxa.com/rock/source/x86_64_arm-eabi-4.6.zip
32bit主机
git clone -b jb-release --depth 1 https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6
或者在这里下载
http://dl.radxa.com/rock/source/x86_32_arm-eabi-4.6.zip
设置环境变量
export ARCH=arm export CROSS_COMPILE=`pwd`/arm-eabi-4.6/bin/arm-eabi-
请确保这些交叉工具链能够正常工作,如有问题请参考错误提示信息清除问题
Get the source code
git clone -b radxa-stable-3.0 https://github.com/radxa/linux-rockchip.git
or download here http://pan.baidu.com/s/1jfOTo (china)
编译内核
cd linux-rockchip
if your Rock is pro(Mid 2014) or the new lite(Mid 2014), use radxa_rock_pro_linux_defconfig, check out hardware revision
make radxa_rock_pro_linux_defconfig
if your rock is full version(2013) or the old lite(2013), use radxa_rock_linux_defconfig, check out hardware revision
make radxa_rock_linux_defconfig
make -j8
生成的内核文件位置是在 arch/arm/boot/Image。
编译内核模块
mkdir modules export INSTALL_MOD_PATH=./modules make modules && make modules_install cd ..
现在所以的内核模块都在 modules/lib/modules/3.0.36+/文件夹中。
生成 ramdisk
git clone https://github.com/radxa/initrd.git find . ! -path "./.git*" | cpio -H newc -ov > initrd.img
生成 boot.img
wget http://dl.radxa.com/rock/tools/linux/mkbootimg sudo apt-get install lib32stdc++6 chmod +x mkbootimg ./mkbootimg --kernel linux-rockchip/arch/arm/boot/Image --ramdisk initrd.img -o boot.img
完成。现在已经生成了RR的“boot.img”文件了。
修改 parameter 文件
linux的根文件系统(rootfs)可能处于不同的分区或者媒介中(比如nand、SD卡或者U盘 ),所以你需要告诉内核应该加载哪一个根文件系统。修改你的parameter文件的“root= ”这一行,指向你想加载的那个根文件系统所存放的分区。比如:
root=/dev/block/mtd/by-name/linuxroot # rootfs 在名叫“linuxroot”的nand分区中 root=/dev/mmcblk0p1 # rootfs 在SD卡第一分区中 root=/dev/sda1 # rootfs 在U盘或者移动硬盘第一分区 root=LABEL=linuxroot # rootfs在标签为“linuxroot”分区,这个分区可能是SD卡、U盘或者移动硬盘。
