1、硬件平台

开发板是飞凌OK335XD

具体参数介绍：https://blog.csdn.net/Ternence_zq/article/details/109691911

OK335XD开发平台基于 TI AM335X 处理器，运行主频最高达 1G，支持 Linux，WinCE， Android 三大操作系统，及 StarterWare 裸机程序，可用于工业产品设计。 OK335xD 由核心板和底板组成，核心板主要芯片有： CPU， NandFlash， Memory， PowerManage。

OK335xD 产品是工业级版本，核心板 FET335xD 也是工业级版本。工业级版本更强调系统在复杂环境下运行的稳定性，比如高低温环境，振动环境，电磁干扰环境。

2、软件平台介绍

移植的要求

交叉编译器至少是4.7，才能支持C++11的新特性，例如lambda表达式等，而且QT开发时，用到这些新特性。

QT下默认C++11是不启用的，要想使用C++11，可以在QT的project里面的.pro文件上加上一行 CONFIG += c++11 ，这样就可以开始使用C++ 11的一些特性了。

具体介绍可以参考该链接：https://blog.csdn.net/haluoluo211/article/details/71141093

3、源码下载与编译

交叉编译器

更新中。。。

4、系统烧录

制作SD卡烧录

推荐方法： 首先将SD卡插入到自己的笔记本SD卡插槽里，准备制作SD卡启动盘。这里建议使用官方推荐的HPUSBFW工具格式化SD卡，该工具可将SD卡分区设置为活动分区，这样开发板在上电的时可以正常从SD卡启动，否则开发板无法失败SD卡信息导致无法正常启动。

另一种方法：使用SD Card Formatter软件来格式化SD卡，但该软件格式化后并不会将相应分区设置为活动分区，导致无法启动。

这时我们可以使用Windows自带的diskpart命令来设置，具体方法为： 首先Windows+R键打开运行，并输入diskpart 运行该命令：

接下来输入相关命令来设置SD卡分区为活动分区：

磁盘格式化分区制作好之后，把之前编译生成的bootloader镜像文件MLO和u-boot.img拷贝到分区根路径下即可：

命令行烧录

OK335X开发板支持SD卡和Nandflash启动，因为Nandflash在出厂时没有程序，所以我们可以从SD卡启动u-boot，然后在U-boot下使用相应命令下载u-boot、linux内核和根文件系统到Nandflash上。其中SD卡和Nandflash启动由下图所示的拨码开关决定：

1. SD 卡启动设置： 1 On, 2 On (On 代表拨到上方，Off 代表拨到下方)
2. NandFlash 启动设置：1 Off ,2 On (On 代表拨到上方，Off 代表拨到下方)

现在，我们将SD卡放入到SD卡槽，并将拨码开关1，2设置到上方，然后将系统上电，这时系统将从SD卡启动：

注意： 现在新买的OK335XD拨码简化成一个，设置SD/Nandflash启动方式如下：

1. SD 卡启动设置： 直接拨到 On(On 代表拨到上方， Off 代表拨到下方)
2. NandFlash 启动设置： 直接拨到 Off(On 代表拨到上方， Off 代表拨到下方)

启动开发板，使用串口监听console口，按任意键停止U-boot的自动启动，然后输入0进入到uboot 命令行模式：

OK335X# setenv ipaddr 192.168.2.222   	//设置U-boot的IP地址
OK335X# setenv serverip 192.168.2.2 	//设置 tftp 服务器的IP地址
OK335X# pri 		//打印u-boot的当前环境变量

OK335X# nand erase.chip 		//擦除整片Nandflash上内容
NAND erase.chip: device 0 whole chip
100% complete
OK

OK335X# save 	//保存环境变量

通过uboot下写的脚本文件，一键编译烧录uboot、内核和根文件系统到Nandflash中：

OK335X# run bsys 		//使用该命令一键烧录u-boot、linux内核和根文件系统

Nandflash启动OK335XD

系统烧录好后，关闭开发板电源并拔除SD卡，然后设置拨码开关从Nandflash启动，并重新上电：

这时我们可以看到系统从Nandflash上启动成功了：

下面是系统上电后的整个启动流程，如果想升级U-boot、Linux内核或文件系统，我们也可以进入到U-boot命令行，用相关命令升级。

5、tslib与QT移植

tslib移植

tslib-1.16下载：。。。
tslib存放的目录为/home/tavi/ok335x/3rdparty/qt/tslib/tslib-1.16
tslib编译的结果存放在/home/tavi/ok335x/3rdparty/install目录下

tavi@Tavi:~/ok335x/3rdparty/install$ ls			//编译结果
bin  etc  include  lib  share
tavi@Tavi:~/ok335x/3rdparty/install$ ls
bin  etc  include  lib  share
tavi@Tavi:~/ok335x/3rdparty/install$ ls etc/
ts.conf
tavi@Tavi:~/ok335x/3rdparty/install$ ls bin/
iconv  ts_calibrate  ts_finddev  ts_harvest  ts_print  ts_print_mt  ts_print_raw  ts_test  ts_test_mt  ts_uinput  ts_verify
tavi@Tavi:~/ok335x/3rdparty/install$ ls lib/
charset.alias  libcharset.la  libcharset.so.1      libiconv.la  libiconv.so.2      libts.la  libts.so.0      pkgconfig                ts
libcharset.a   libcharset.so  libcharset.so.1.0.0  libiconv.so  libiconv.so.2.6.0  libts.so  libts.so.0.9.1  preloadable_libiconv.so
tavi@Tavi:~/ok335x/3rdparty/install$ ls include/
iconv.h  libcharset.h  localcharset.h  tslib.h

将以上的etc、lib、plugins、bin、share和include文件夹及所有内容全部打包压缩，拷贝到开发板当中。
其中bin文件里面是tslib的测试程序、lib为程序执行时需要的动态库、etc为tslib的模块配置。

注： 一般通过PC上的tftp软件，通过网线形成局域网进行传输

tftp 192.168.1.231 -g -r etc.tar.gz

配置完成后，更改开发板的环境变量，我的环境变量如下：

/opt/QT5.9_A8/tslib >: pwd
/opt/QT5.9_A8/tslib
/opt/QT5.9_A8/tslib >: vim /etc/profile 
# ~/.bashrc: executed by bash(1) for non-login interactive shells.

export PATH=\
/bin:\
/sbin:\
/usr/bin:\
/usr/sbin:\
/opt/QT5.9_A8/lib

export PS1='\w >: '

export USER=`id -un`
export LOGNAME=$USER
export HOSTNAME=`/bin/hostname`
export HISTSIZE=500
export HISTFILESIZE=500
export PAGER='/bin/more '
export EDITOR='/bin/vi'
export INPUTRC=/etc/inputrc
export network_cfg_dir=/apps/etc/network

### Some aliases
alias vim='vi'
alias ll='ls -l'
alias l.='ls -d .*'
alias df='df -h'

# QT configuration
export QTDIR=/opt/QT5.9_A8				//开发板上QT存放的路径
export QT_QPA_FONTDIR=$QTDIR/fonts		//还未移植fonts，这里写了但是没有该文件夹
export QT_QPA_PLATFORM_PLUGIN_PATH=$QTDIR/plugins/
export LD_LIBRARY_PATH=$QTDIR/lib:$QTDIR/tslib/lib:$LD_LIBRARY_PATH 
export QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0:size=1024x600:mmSize=1024x600:offset=0x0:tty=/dev/tty1 

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib:/usr/lib
export PATH=$PATH:/opt/QT5.9_A8/tslib/lib

# Touch Screen configuration
export QT_QPA_GENERIC_PLUGINS=tslib
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/dev/input/event0
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONFFILE=$QTDIR/tslib/etc/ts.conf
export TSLIB_PLUGINDIR=$QTDIR/tslib/plugins
export QML2_IMPORT_PATH=$QTDIR/qml		//为了QT支持QML模块，没有用到可以不写

最后测试tslib移植是否完成，运行ts_calibrate校准程序，开发板能弹出该界面即可成功（这里把bin文件夹名称改为tests文件夹了）

/opt/QT5.9_A8/tslib >: ls
etc      include  lib      plugins  share    tests
/opt/QT5.9_A8/tslib >: cd tests/
/opt/QT5.9_A8/tslib/tests >: ls
iconv               ts_print_mt         ts_uinput_start.sh
ts_calibrate        ts_print_raw        ts_verify
ts_finddev          ts_test             ts_verify_ts.conf
ts_harvest          ts_test_mt
ts_print            ts_uinput
/opt/QT5.9_A8/tslib/tests >: ./ts_calibrate 

移植tslib的一些小问题：https://blog.csdn.net/Ternence_zq/article/details/109778136

官网下载QT：http://download.qt.io/archive/qt/5.9/5.9.8/single/qt-everywhere-opensource-src-5.9.8.tar.xz

QT移植

通过自己写的脚本build_QT5.sh一键编译安装

tavi@Tavi:~/ok335x/3rdparty/qt$ ls
build_QT5.sh  iconv  qt-everywhere-opensource-src-5.9.8  qt-everywhere-opensource-src-5.9.8.tar.xz  tslib
tavi@Tavi:~/ok335x/3rdparty/qt$ sudo ./build_QT5.sh 

因为在根文件系统新建了/app文件夹，所以要用sudo
编译出来的结果如下：

tavi@Tavi:/apps/QT5.9_A8$ ls
bin  doc  include  lib  mkspecs  plugins  qml  translations

将lib动态库、plugins插件、qml支持文件全部拷贝到开发板当中，同样可以通过tftp进行下载。

环境变量更改在tslib那部分展示的一样

/opt/QT5.9_A8 >: ls		//拷贝到开发板当中的文件（夹），tslib之前已拷贝
bin      lib      plugins  qml      tslib
/opt/QT5.9_A8 >: vim /etc/profile 

到次就完成了QT的移植了

测试： 可以在Ubuntu下新建测试文件，配置交叉编译器，生成可执行文件，拷贝到开发板上面运行即可。
