一，准备

1,x86_64位的ubuntu 12.04的系统

2,pcDuino 3A/3B/NANO

说明，在软件中#表示在x86的ubuntu里面运行的指令，$表示在pcDuino运行的指令；

二，制作从TF卡启动的系统，

把TF插入到pcDuino上面，建议选择大于8G的TF卡，执行

$board-config.sh

 

选择make_mmc_boot,大概10分钟以后你就会得到一个从TF卡启动的系统。这时候你重启系统，就是从TF卡启动，这里需要注意一下，你需要扩展一下你的系统，才能使用TF卡所有的内存。再次执行$board-config.sh 。

选择expand_rootfs之后就可以进入可用空间比较大的系统了。

二，添加Mali400驱动，

1，下载a20_kernel源码。

$git clone https://github.com/pcduino/a20-kernel

$cd a20_kernel

$make

2，由于Mali400有些库不开源，不能采用分离编译，只能在linux-sunxi里面本地编译。

$git clone  https://github.com/Pillar1989/Qt5.3.2forPcDuino3

$cp Qt5.3.2forPcDuino3/mali_r3p2-01rel2 linux-sunxi/drivers/gpu/

然后在整个源码里打上0003-Sunxi-adaptation-for-mali-r3p2-01rel2-kernel-module.patch这个补丁

Subject: [PATCH] Sunxi adaptation for mali r3p2-01rel2 kernel module
Tested only on A10 and A20.
TODO:
- bus addresses vs. physical addresses?
- umplock?
- power management (disable clocks when idle)?
- drm upgrade (and also fix compatibility with xf86-video-modesetting)?

1.8.3.2

打完补丁以后，重新编译内核。pcDuino系列默认的framebuff都是640×480.你可以在

drivers/video/sunxi/disp/dev_fb.c

里面43行修改：

static char *screen0_output_mode=”1920x1080p50″;

这里我修改到了1080p.

3,重新编译内核

$make ARCH=arm  sun7i_defconfig

$make -j 8 uImage ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

$make -j 8 modules ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

$make -j 8 firmware_install modules_install INSTALL_MOD_PATH=../modules ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

编译结束以后，你会在arch/arm/boot/下面得到新的uImage。在 ../modules/lib/modules/下面会得到新的内核modules。

把uImage拷贝到TF卡的第一分区。把新的3.4.79的内核模块拷贝到系统的/lib/modules/下面，重启系统，这时候你会发现屏幕的字符输出变成了1080P。

$lsmod

mali 224755 1
disp_ump 861 0
ump 33016 6 mali,disp_ump

里面有最新的mali和disp_ump.

三，添加应用里面支持openesgl的库以及其他的软件库。

1，安装依赖软件

$sudo apt-get install libssl-dev libasound2-dev  libxcb-icccm4-dev  libxcb-xfixes0-dev libxcb-image0-dev  libxcb-keysyms1-dev libxcb-sync0-dev libxcb-render-util0-dev libxcb-randr0-dev  libx11-dev libxrender-dev  libicu-dev  libx11-xcb-dev libxext-dev git build-essential autoconf libtool automake

2,安装ump.

$git clone https://github.com/linux-sunxi/libump.git

$cd libump

$autoreconf -i
$./configure --prefix=/usr
$make
$make install
3,安装sunxi_mali

$cd Qt5.3.2forPcDuino3/sunxi_mali

$ make config VERSION=r3p2-01rel1 ABI=armhf EGL_TYPE=framebuffer
$make
$make install

$make test

Note
/* for X11 */

EGL_TYPE=x11

这时候你可以使用键盘,按住ctrl+alt+F1,这时候进入字符界面

$cd sunxi-mali/test

$./test

 

四，交叉编译qt-everywhere-opensource-src-5.3.2.

1,TF卡插入到x86的ubuntu系统里面,然后把

#mkdir rootfs

2，挂载TF卡的文件系统的到rootfs上面

#mount /dev/sdb2 rootfs

3,下载qt-everywhere-opensource-src-5.3.2

#wget http://download.qt.io/official_releases/qt/5.3/5.3.2/single/qt-everywhere-opensource-src-5.3.2.tar.xz

#tar xvf  qt-everywhere-opensource-src-5.3.2.tar.xz

#cd qt-everywhere-opensource-src-5.3.2

4，拷贝pcDuino3设备到Qt

#cp ../Qt5.3.2forPcDuino3/linux-pcDuino3-g++   qtbase/mkspecs/devices/ -rf

这里需要注意，打开linux-pcDuino3-g++ 里的

39 QMAKE_INCDIR_EGL        = /home/pillar/Qt/rootfs/usr/include/EGL
40 QMAKE_LIBDIR_EGL        = /home/pillar/Qt/rootfs/usr/lib
41 QMAKE_INCDIR_OPENGL_ES2 = /home/pillar/Qt/rootfs/usr/include/GLES2
42 QMAKE_LIBDIR_OPENGL_ES2 = /home/pillar/Qt/rootfs/usr/lib

你需要修改成自己的路径。

5，修改Qt源码的qtbase/src/plugins/platforms/eglfs/qeglfshooks_stub.cpp

#vim qtbase/src/plugins/platforms/eglfs/qeglfshooks_stub.cpp

                                                    const QSurfaceFormat &format)
{
    Q_UNUSED(platformWindow);
    Q_UNUSED(size);
    Q_UNUSED(format);
    //return 0;
    static struct mali_native_window native_window = {
        .width = (short unsigned int)size.width(),
        .height = (short unsigned int)size.height(),
    };
    return &native_window;
}

6,配置Qt

1
#./configure -opengl es2 -no-linuxfb -system-xcb -system-zlib -no-pch -eglfs -device linux-pcDuino3-g++ -device-option CROSS_COMPILE=/home/pillar/Qt/gcc-arm/bin/arm-linux-gnueabihf- -sysroot /home/pillar/Qt/rootfs -opensource -confirm-license -optimized-qmake -release -make libs -prefix /usr/local/qt5 -qreal float -v

下面是配置的结果。

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /usr/local/qt5
Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

#make -j 8

#sudo make install

我用四核的电脑，编译大概2个小时。

编译结束以后，相关的库都会安装到TF卡rootfs的/usr/local/qt5，而相应的开发工具都会按照到本地的/usr/local/qt5。

五，编译应用。

这里我选择比较经典的。Qt5_CinematicExperience

#cd Qt5.3.2forPcDuino3/Qt5_CinematicExperience_1.1

# export PATH=/usr/local/qt5/bin:$PATH

#qmake

#make

编译结束以后把整个工程都拷贝到板子上面。然后在字符界面下面执行

$./Qt5_CinematicExperience -platform eglfs
