感谢各位亲的厚爱，很抱歉，本人从今年一月份就没有从事rk3288的开发了，所以本帖一直没有更新维护，但是之前开发的资料和源码一直保留在Github上面。
相关内容请直接去Github上获取，链接：https://github.com/luwanjia/rockchip-dev
rockchip-dev/RK3288_Technical_Reference_Manual.md 是本人自己总结和验证过的手册，大家可以参考。
目录rockchip-dev/linux-rootfs/下面的01~07是完整的步骤，初学者可以一步一步的来。
This manual is for the development of linux on RK3288 board. My operating system is debian8.7 x64.
1. Set develop environment
We need arm-eabi-gcc to compile the kernel, arm-eabi-4.6 and arm-eabi-4.8 are available in AndroidSDK_5.1, you can find it in path "AndroidSDK_5.1/prebuilts/gcc/linux-x86/arm".
Here I use arm-eabi-4.8, you can download it directly here. (链接: https://pan.baidu.com/s/1nvSfSPr 密码: 4ssx)
2. Build kernel
1> Download source code of kernel4.4 for linux.
$git clone https://github.com/luwanjia/linux-kernel
2> Change to right branch
$git checkout firefly
3> Config whith right configure file.
$export ARCH=arm
$export CROSS_COMPILE=<path to arm-eabi-gcc root dir>/bin/arm-eabi-
$make rockchip_linux_defconfig
$make rk3288-firefly.img
4> If there is no errors, the last print log is:
OBJCOPY arch/arm/boot/zImage
Kernel: arch/arm/boot/zImage is ready
Image: kernel.img is ready
Pack to resource.img successed!
Image: resource.img (with rk3288-firefly.dtb logo.bmp) is ready
3. Build initrd
1> Download source code
$git clone https://github.com/TeeFirefly/initrd.git
2> Change to branch for-kernel_4.4
$git checkout for-kernel_4.4
3> Build in parent directory of initrd root directory.
$make -C initrd
4> If there is no errors, initrd.img will be generated.
4. Pack zImage and initrd.img into the linux-root.img
$mkbootimg --kernel kernel_4.4/arch/arm/boot/zImage --ramdisk initrd.img --second kernel_4.4/resource.img -o linux-boot.img
Now, linux-boot.img is OK, it will be used in step6.
5. Make the rootfs of ubuntu16.04
1> First, please download the minimum core of ubuntu
$wget -c http://cdimage.ubuntu.com/ubuntu ... 4-core-armhf.tar.gz
2> unpack
$mkdir linux-rootfs
$sudo tar -xpf ubuntu-base-16.04-core-armhf.tar.gz -C linux-rootfs
3> Install the simulator to run the root file system
$sudo apt-get install qemu-user-static
$sudo cp /usr/bin/qemu-arm-static linux-rootfs/usr/bin/
4> Copy the local host DNS configure to rootfs
$sudo cp -b /etc/resolv.conf linux-rootfs/etc/resolv.conf
5> Add additional sources of port ubuntu, append follow strings to linux-rootfs/etc/apt/sources.list as administrator
deb http://ports.ubuntu.com/ubuntu-ports/ xenial main universe
deb-src http://ports.ubuntu.com/ubuntu-ports/ xenial main universe
6> Use a mount script file to mount the core file system. Please see file ch-mount.sh, and add executable permissions.
ch-mount.sh Link：
ch-mount.sh.tar.gz
(473 Bytes, 下载次数: 205)
$sudo chmod +x ch-mount.sh
7> Mount rootfs, Notice that do not excute the script as administrator, otherwise errors will occur.
$./ch-mount.sh -m linux-rootfs
Now, you will enter the simulate bash as root, you can install any packages you want to integrate.
a) Install network tools to make ifconfig command work.
#apt-get install net-tools
b) #apt-get install vim openssh-server
c) #apt-get install ubuntu-session xubuntu-desktop
Please wait to be done.
Start dbus server to solve the error:
Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory
#/etc/init.d/dbus start
d) Enable auto connect to network
#echo auto eth0 > /etc/network/interfaces.d/eth0
#echo iface eth0 inet dhcp >> /etc/network/interfaces.d/eth0
e) Setup startup desktop
#update-alternatives --config x-session-manager
Selection:
desktop | x-session
---------------------
xubuntu | startxfce4
---------------------
lubuntu | startlxde
f) Set default login screen
#dpkg-reconfigure lightdm
g) Set the user and password to login
#useradd -s '/bin/bash' -m -G adm,sudo ubuntu
#passwd ubuntu
#passwd root
h) Exit from simulate bash
#exit
8> After your installations in rootfs, please unmount the rootfs:
$./ch-mount.sh -u linux-rootfs
9> Create an empty image disk to save rootfs
$dd if=/dev/zero of=linux-rootfs.img bs=1M count=4096
$sudo mkfs.ext4 -F -L linuxroot linux-rootfs.img
10> Mount the image disk, and copy the rootfs to it
$mkdir mnt
$sudo mount linux-rootfs.img mnt
$sudo cp -rfp linux-rootfs/* mnt/
11> Unmount the image disk and resize it.
$sudo umount mnt
$/sbin/e2fsck -p -f linux-rootfs.img
$/sbin/resize2fs -M linux-rootfs.img
12> Now, rootfs is done. linux-rootfs.img will be used in step6.
6. Make one key update package.
1> We need linux-boot.img and linux-rootfs.img created just now. And the tools to flash them into board.
In AndroidSDK_5.1, the tools is avaiable:
AndroidSDK_5.1/RKTools/linux/Linux_Upgrade_Tool_v1.2/rockdev
2> Copy rockdev to somewhere as you want. And copy linux-rootfs.img and linux-rootfs.img to rockdev/Image directory.
3> Do some modifications for parameter and package-file, and run mkupdate.sh
Maybe you don't know how to modify parameter and package-file, it does't matter, you can unpack an official package, and you will get these two files.
a) Unpack an official package, I use Firefly-rk3288_Ubuntu_1604_2016_10181203_Beta.img as official package.
$mv Firefly-rk3288_Ubuntu_1604_2016_10181203_Beta.img update.img
$./unpack.sh
After that, you will get all the files you need.
b) Make update.img
$./mkupdate.sh
Notice that, you should add the excutable permissions to all script files.
4> Now, update.img will generated here.
7. Flash update.img to board.
1> Press the recovery button and reset button at the same time.
2> Free the reset button and hold on the recovery button for more than 2 seconds.
3> Now, the board entry the flash model, and use follow command to flash:
$sudo upgrade_tool uf update.img
4> Please wait, after flash success, the board will reboot automatically.
