Learn ZYNQ (3)

移植android3.3到ZedBoard

follow website: http://elinux.org/Zedboard_Android

（1）在Ubuntu12.04LTS下安装编译所需环境：

sudo apt-get install git gnupg flex bison gperf build-essential

zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev

libx11-dev:i386 libreadline6-dev:i386 libglapi-mesa:i386 libgl1-mesa-glx:i386

libgl1-mesa-dev g++-multilib mingw32 tofrodos  python-markdown

libxml2-utils xsltproc zlib1g-dev:i386 uboot-mkimage gparted screen

（2）下载和安装jdk：

从以下网址下载jdk-6u45-linux-i586.bin

http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-419409.html

进入编译目录

chmod u+x jdk-6u45-linux-i586.bin

./jdk-6u45-linux-i586.bin

mkdir -p /usr/lib/jvm

mv jdk1.6.0_45 /usr/lib/jvm/

update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.6.0_45/bin/java" 1

update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.6.0_45/bin/javac" 1

update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.6.0_45/bin/javaws" 1

update-alternatives --install "/usr/lib/mozilla/plugins/libjavaplugin.so" "mozilla-javaplugin.so" "/usr/lib/jvm/jdk1.6.0_45/jre/lib/i386/libnpjp2.so" 1

//若是64位版，路径为/usr/lib/jvm/jdk1.6.0_45/jre/lib/amd64/libnpjp2.so

update-alternatives --config java

update-alternatives --config javac

update-alternatives --config javaws

update-alternatives --config mozilla-javaplugin.so

复制以下段落到~/.bashrc

JAVA_HOME=/usr/lib/jvm/jdk1.6.0_45/
JRE_HOME=${JAVA_HOME}/jre
export ANDROID_JAVA_HOME=$JAVA_HOME
export CLASSPATH=.:${JAVA_HOME}/lib:$JRE_HOME/lib:$CLASSPATH
export JAVA_PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin
export JAVA_HOME;
export JRE_HOME;
export CLASSPATH;
HOME_BIN=~/bin/
export PATH=${PATH}:${JAVA_PATH}:${HOME_BIN};

（3）下载Linux 源

git clone https://github.com/Digilent/linux-digilent.git

（4）下载Android Kernel

git clone https://android.googlesource.com/kernel/common -b android-3.3

在疆目录下建立bin目录并将其添加到path环境变量,并下载REPO脚本

mkdir ~/bin

export PATH=~/bin:$PATH

curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo

给repo加权限

chmod a+x ~/bin/repo

cd YourWorkspace

新建repo疆目录，repo将安装在此目录下，然后安装最新的repo（在2M网速下可能需要1天或更久）

repo init -u https://android.googlesource.com/platform/manifest

repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.1_r1

repo sync

准备BOOT.BIN(FSBL,SSBL,)。。。[Hardware Design Source folder]中有

wget http://www.digilentinc.com/Data/Products/ZedBoard/ZedBoard_Linux_Design.zip

解压后在sd_image目录下可以发现sd卡boot分区需要装载的所有文件

（5）kernel编译:

cd ~/android_for_zed

vi dev.sh

粘贴以下代码

#!/bin/bash
export CCOMPILER=arm-xilinx-linux-gnueabi-gcc
export ARCH=arm
export CROSS_COMPILE=arm-xilinx-linux-gnueabi-
export PATH=$PATH:/root/CodeSourcery/bin/

其中CodeSourcery是交叉编译工具链，自行去xilinux，git

cd ~/android_for_zed/linux-digilent

make digilent_zed_defconfig

sudo apt-get install build-essential
sudo apt-get install libncurses5
apt-get install libncurses5-dev

make menuconfig

Linux运行情况测试：

（6）编译安卓：

打开USB OTG键盘输入功能：

cd ~/android_for_zed/frameworks/base/policy/src/com/android/internal/policy/impl

vi PhoneWindowManager.java

cd ~/android_for_zed

source build/envsetup.sh

lunch generic-eng

make

error solving:

apt-get install gcc-4.4 g++-4.4 g++-4.4-multilib gcc-4.4-multilib

ls /usr/bin/gcc* –l

update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.4 50
update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.4 50

update-alternatives --config gcc

sudo apt-get install libncurses5-dev:i386

错误找不到libGL库：

ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

编译成功：

（7）打包镜像

cd ~/android_for_zed/

vi Makefile.zynq

输入以下代码：

OUT_DIR:=out/target/product/generic
ROOT_IMG:=root.img
ROOTFS:=rootfs
ROOT_DIRS=lib/modules tmp media

.PHONY: dummy

$(ROOT_IMG): dummy
        rm -rf $@
        sudo rm -rf $(ROOTFS)
        cp -r $(OUT_DIR)/root $(ROOTFS)
        cp -r $(OUT_DIR)/system $(ROOTFS)
        cd $(ROOTFS) && mkdir -p $(ROOT_DIRS)
        sudo chown -R root:root $(ROOTFS)
        sudo genext2fs -d $(ROOTFS) -b $$((80*1024)) -m 0 -N $$((64*1024)) $(ROOT_IMG)
        sudo chown $(shell id -u):$(shell id -g) $(ROOT_IMG)

# Phony target forces the rootfs image file to be rebuilt on each make
dummy:

注意遵循Makefile语法，每行后面不能有空格，命令以Tab开头。

apt-get install genext2fs

make –f Makefile.zynq

这一步生成 root.img 文件系统镜像。

（8）准备运行

cd ~/android_for_zed/ready_to_download

gunzip ramdisk8M.image.gz

mkdir -p temp

mount ramdisk8M.image -o loop temp/

cd ~/android_for_zed/ready_to_download/temp/etc/init.d

vi rcS

echo "Mounting SD card to /mnt/sd"
mkdir -p /mnt/sd
mount /dev/mmcblk0p1 /mnt/sd
echo "++ Starting startup.sh script on SD card"
if [ -f /mnt/sd/startup.sh ]; then
    ./mnt/sd/startup.sh
fi

cd ~/android_for_zed/ready_to_download/

umount temp/

gzip ramdisk8M.image

vi startup.sh

粘贴下面的代码：

echo "++ Preparing for Android" 
mkdir /mnt/root 
mount -o loop /mnt/sd/root.img /mnt/root/ 
mount -t proc proc /mnt/root/proc 
mount -t sysfs sys /mnt/root/sys 
mount -t tmpfs tmp /mnt/root/data 
mkdir -p /mnt/root/tmp/sd 
mount /mnt/sd /mnt/root/tmp/sd 
echo "++ Starting Android" 
chroot /mnt/root /init

chmod 777 startup.sh

拷贝文件到SD卡:

BOOT.BIN	来自硬件工程
devicetree.dtb	来自硬件工程
ramdisk8m.image.gz	修改自硬件工程
root.img	安卓编译后产生复制到sd卡ext分区
startup.sh	刚写的
zImage	来自linux内核编译

（9）运行问题解决方法

cp ~/android_for_zed/out/target/product/generic/obj/SHARED_LIBRARIES/gralloc.default_intermediates/LINKED/gralloc.default.so ~/android_for_zed/rootfs/system/lib/hw/

cd ~/android_for_zed/rootfs

vi vi init.rc

错误

在回到make menuconfig步骤看看, 在common外make clean 后会覆盖前面的设置。

VGA（HDMI）

[Hardware Design Source folder]：/root/android_for_zed/ZedBoard_Linux_Design/

[Xillinux sources folder] : /root/android_for_zed/xillinux-eval-zedboard-1.2/

（5）下载 Xillinux sources :

wget http://www.xillybus.com/downloads/xillinux-eval-zedboard-1.2.zip

cd ~/android_for_zed/

cp -r xillinux-eval-zedboard-1.2/system/pcores/xillyvga_v1_00_a/ ZedBoard_Linux_Design/hw/xps_proj/pcores/

cd ~/android_for_zed/ZedBoard_Linux_Design/hw/xps_proj/pcores/xillyvga_v1_00_a

mkdir netlist

安装ISE14.4

用ISE打开~/android_for_zed/xillinux-eval-zedboard-1.2/runonce

regenerate core

完成后：

cd ~/android_for_zed/

cp xillinux-eval-zedboard-1.2/runonce/vga_fifo.v ZedBoard_Linux_Design/hw/xps_proj/pcores/xillyvga_v1_00_a/hdl/verilog/

cp xillinux-eval-zedboard-1.2/runonce/vga_fifo.ngc ZedBoard_Linux_Design/hw/xps_proj/pcores/xillyvga_v1_00_a/netlist/

cp xillinux-eval-zedboard-1.2/cores/xillyvga_core.ngc ZedBoard_Linux_Design/hw/xps_proj/pcores/xillyvga_v1_00_a/netlist/

cd ~/android_for_zed/ZedBoard_Linux_Design/hw/xps_proj/pcores/xillyvga_v1_00_a/data

vi xillyvga_v2_1_0.pao

加入一行lib xillyvga_v1_00_a vga_fifo verilog

cd ~/android_for_zed/ZedBoard_Linux_Design/hw/xps_proj/pcores/xillyvga_v1_00_a/hdl/verilog

vi xillyvga.v

最后加入一段

FDCE vga_iob_ff[13:0] (

.Q({vga_red, vga_green, vga_blue, vga_hsync, vga_vsync}),

.D({vga_red_app[7:4], vga_green_app[7:4], vga_blue_app[7:4], vga_hsync_app, vga_vsync_app}),

.C(vga_clk_app),

.CE(1'b1),

.CLR(1'b0)

);

在第69行修改

output [3:0] vga_blue,

output [3:0] vga_green,

output vga_hsync,

output [3:0] vga_red,

cd ~/android_for_zed/ZedBoard_Linux_Design/hw/xps_proj/pcores/xillyvga_v1_00_a/data/

vi xillyvga_v2_1_0.bbd

加入以下3行：

Files

#####

vga_fifo.ngc,xillyvga_core.ngc

vi xillyvga_v2_1_0.mpd

第90行那里，改三行：

PORT vga_red = "", DIR = O, VEC = [3:0]

PORT vga_green = "", DIR = O, VEC = [3:0]

PORT vga_blue = "", DIR = O, VEC = [3:0]

第7行后插入两行：

OPTION STYLE = MIX

OPTION RUN_NGCBUILDF = TRUE

用ISE的XPS打开~/android_for_zed/ZedBoard_Linux_Design/hw/xps_proj/system.xps如下图

点击BUS INTERFACE的TAB页

删除axi_hdmi_tx_16_b0, axi_iic_hdmi, axi_vdma_0共三项

打开system.mhs,修改152行去掉hdmi_int，

点IP Catalog ->Project local PCores ->User –> XILLYVGA

将VGA通过INTERCONNECT3链接到ZYNC，其他接线如图所示

点Ports->Xillvga_0,将如图所示几个端口MakeExernel

OK，Generate bitstream.

4 Prepare the kernel for Android
