<p>Cyhgxu: </p> <hr /> <div>=== 开发要求 ===<br /> * radxa rock (全版或者简版)<br /> * 64bit Linux (e.g. Ubuntu) 开发环境<br /> * micro USB 数据线<br /> * 5V/2A的电源<br /> <br /> === Install the toolchain ===<br /> <br /> 下载交叉编译工具链<br /> <br /> 64bit 主机<br /> <br /> git clone -b kitkat-release --depth 1 https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6<br /> <br /> 或者从这里下载<br /> <br /> [http://dl.radxa.com/rock/source/x86_64_arm-eabi-4.6.zip http://dl.radxa.com/rock/source/x86_64_arm-eabi-4.6.zip ]<br /> <br /> <br /> 32bit主机<br /> <br /> git clone -b jb-release --depth 1 https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6<br /> <br /> 或者在这里下载<br /> <br /> [http://dl.radxa.com/rock/source/x86_32_arm-eabi-4.6.zip http://dl.radxa.com/rock/source/x86_32_arm-eabi-4.6.zip]<br /> <br /> <br /> 设置环境变量<br /> <br /> export ARCH=arm<br /> export CROSS_COMPILE=`pwd`/arm-eabi-4.6/bin/arm-eabi-<br /> <br /> 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<br /> <br /> <br /> <br /> <br /> <br /> <br /> === Get the source code ===<br /> <br /> git clone -b radxa-stable-3.0 https://github.com/radxa/linux-rockchip.git<br /> <br /> or download here<br /> http://pan.baidu.com/s/1jfOTo (china)<br /> <br /> === 编译内核 ===<br /> <br /> cd linux-rockchip<br /> <br /> if your Rock is pro(Mid 2014) or the new lite(Mid 2014), use radxa_rock_pro_linux_defconfig, check out [[Rock/hardware_revision| hardware revision]]<br /> make radxa_rock_pro_linux_defconfig<br /> <br /> if your rock is full version(2013) or the old lite(2013), use radxa_rock_linux_defconfig, check out [[Rock/hardware_revision| hardware revision]]<br /> make radxa_rock_linux_defconfig<br /> <br /> make -j8<br /> <br /> 生成的内核文件位置是在 '''arch/arm/boot/Image'''。<br /> <br /> === 编译内核模块 ===<br /> mkdir modules<br /> export INSTALL_MOD_PATH=./modules<br /> make modules &amp;&amp; make modules_install<br /> cd ..<br /> 现在所以的内核模块都在 '''modules/lib/modules/3.0.36+/'''文件夹中。<br /> <br /> === 生成 ramdisk ===<br /> <br /> git clone https://github.com/radxa/initrd.git<br /> make -C initrd<br /> <br /> === 生成 boot.img ===<br /> wget http://dl.radxa.com/rock/tools/linux/mkbootimg<br /> sudo apt-get install lib32stdc++6<br /> chmod +x mkbootimg<br /> ./mkbootimg --kernel linux-rockchip/arch/arm/boot/Image --ramdisk initrd.img -o boot.img<br /> <br /> 完成。现在已经生成了RR的“boot.img”文件了。<br /> <br /> === 修改 parameter 文件===<br /> 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：<br /> root=/dev/block/mtd/by-name/linuxroot # rootfs 在名叫“linuxroot”的nand分区中<br /> root=/dev/mmcblk0p1 # rootfs 在SD卡第一分区中<br /> root=/dev/sda1 # rootfs 在U盘或者移动硬盘第一分区<br /> 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。</div>
