目录 Linux 3.3.5系统移植    2 LED驱动移植    8 按键驱动移植    9 LCD驱动移植    11 DM9000网卡驱动移植    14 搭建NFS网络文件系统    25 移植触摸屏驱动    38 移植Qt4.8.1    42 tslib移植及测试    42 移植qt-everywhere-opensource-src-4.8.1    45   Linux 3.3.5系统移植 将arch/arm/mach-s3c6410/下的,mach-smdk6410.c cp为mach-my6410.c; 打开arch/arm/mach-s3c6410/下的Kconfig,仿照MACH_SMDK6410做一个菜单项: config MACH_MY6410     bool "MY6410"     select CPU_S3C6410     select SAMSUNG_DEV_ADC     select S3C_DEV_HSMMC     select S3C_DEV_HSMMC1     select S3C_DEV_I2C1     select SAMSUNG_DEV_IDE     select S3C_DEV_FB     select S3C_DEV_RTC     select SAMSUNG_DEV_TS     select S3C_DEV_USB_HOST     select S3C_DEV_USB_HSOTG     select S3C_DEV_WDT     select SAMSUNG_DEV_BACKLIGHT     select SAMSUNG_DEV_KEYPAD     select SAMSUNG_DEV_PWM     select HAVE_S3C2410_WATCHDOG if WATCHDOG     select S3C64XX_SETUP_SDHCI     select S3C64XX_SETUP_I2C1     select S3C64XX_SETUP_IDE     select S3C64XX_SETUP_FB_24BPP     select S3C64XX_SETUP_KEYPAD     help      Machine support for the Pillar MY6410 打开arch/arm/tools/mach-types文件,这里面存的是机器ID必须要和uboot里面的ID保持一致,将其283行复制添加在后面并修改为: smdk6410        MACH_SMDK6410        SMDK6410        1626 xx6410  MACH_XX6410  XX6410  1626 这个机器ID和UBOOT里的机器ID相同时才能启动内核; 修改BSP文件mach-my6410.c,内容如下: 将mach-mach-my6410.c文件中的所有smdk6410改成my6410(不要改大写SMDK6410的) MACHINE_START(MY6410, "MY6410")//这个要和Kconfig里的MACH-MY6410匹配  在当前目录的Makefile最后一行加上 obj-$(CONFIG_MACH_MY6410) += mach-my6410.o  修改顶层的Makefile:  ARCH ?= arm  CROSS_COMPILE ?= /usr/local/arm/4.2.2-eabi/usr/bin/arm-linux- 复制arch/arm/configs/下的s3c6400-defconfig文件,然后将其保存为.config,配置内核支持EABI,再选中XX6410 board这一项,保存退出; 执行make menuconfig对内核进行配置: 执行make编译 执行make zImage生成zImage 将uboot根目录下的mkimage拷贝到/user/bin目录下 执行make uImage生成uImage 通过以上几步linux内核移植完了,剩下就移植驱动了。 这里需要注意,每一次修改Kconfig文件都需要make menuconfig对内核进行配置。   LED驱动移植 Linu内核下drivers/leds/leds­gpio.c实现了一个体系结构无关的GPIO LED驱动,使用此LED 驱动,开发者不需要修改一行代码,只需要在 BSP 的板文件(对于OK6410 为arch/arm/mach­s3c6410/mach­my6410.c)中定义相关的platform设备和数据。在 MY6410开发板上,GPM0~GPM3 实现了四个 LED,因此其对应的platform 信息如下: arch/arm/mach­s3c6410/mach­my6410.c: static struct gpio_led my6410_leds[] ={     [0]= {         .name = "LED1",         .gpio = S3C64XX_GPM(0),         },     [1]= {         .name = "LED2",         .gpio = S3C64XX_GPM(1),         },     [2]= {         .name = "LED3",         .gpio = S3C64XX_GPM(2),         },     [3]= {         .name = "LED4",         .gpio = S3C64XX_GPM(3),         },     }; static struct gpio_led_platform_data my6410_gpio_led_pdata ={     .num_leds    = ARRAY_SIZE(my6410_leds),     .leds         =my6410_leds, }; static struct platform_device my6410_device_led ={     .name    = "leds-gpio",     .id        = -1,     .dev    ={     .platform_data = &my6410_gpio_led_pdata,     }, }; 将&my6410_device_led添加到static struct platform_device *my6410_devices[] __initdata中。 配置内核: Device Drivers --->     [*] LED Support --->         <*> LED Support for GPIO connected LEDs 下载内核后开发板上的四个LED这时候已经全部都亮了   按键驱动移植 Linux内核下的drivers/input/keyboard/gpio_keys.c 实现了一个体系结构无关的 GPIO 按键驱动,使用此按键驱动,开发者不需要修改一行代码,只需要在BSP 的板文件(对于 MY6410为arch/arm/mach­s3c6410/mach­my6410.c)中定义相关的platform 设备和数据。在 MY6410开发板上,用 GPN0~GPN5实现了DOWN、ENTER、HOME、UP、TAB、END 六个按键,因此其对应的 platform 信息如下: arch/arm/mach­s3c6410/mach­my6410.c: static struct gpio_keys_button my6410_buttons[] = {     {         .gpio        = S3C64XX_GPN(0),         .code        = KEY_UP,         .desc        = "Up",         .active_low    = 1,         .wakeup        = 0,     },     {         .gpio        = S3C64XX_GPN(1),         .code        = KEY_DOWN,         .desc        = "Down",         .active_low    = 1,         .wakeup        = 0,     },     {         .gpio        = S3C64XX_GPN(2),         .code        = KEY_LEFT,         .desc        = "Left",         .active_low    = 1,         .wakeup        = 0,     },     {         .gpio        = S3C64XX_GPN(3),         .code        = KEY_RIGHT,         .desc        = "Right",         .active_low    = 1,         .wakeup        = 0,     },     {         .gpio        = S3C64XX_GPN(4),         .code        = KEY_ENTER,         .desc        = "Enter",         .active_low    = 1,         .wakeup        = 0,     },     {         .gpio        = S3C64XX_GPN(5),         .code        = KEY_ESC,         .desc        = "Esc",         .active_low    = 1,         .wakeup        = 0,     } }; static struct gpio_keys_platform_data my6410_button_data ={     .buttons    =my6410_buttons,     .nbuttons    =ARRAY_SIZE(my6410_buttons), }; static struct platform_device my6410_device_button    = {     .name        ="gpio-keys",     .id            = -1,     .dev        = {     .platform_data =&my6410_button_data,     }, }; 将& my6410_device_button添加到static struct platform_device *my6410_devices[] __initdata中 配置linux内核 Device Drivers --->     Input device support --->         [*] Keyboards --->              <*> GPIO Buttons 在移植按键驱动时候可能出现一下错误: arch/arm/mach-s3c64xx/mach-my6410.c:298: error: array type has incomplete element type arch/arm/mach-s3c64xx/mach-my6410.c:300: error: field name not in record or union initializer arch/arm/mach-s3c64xx/mach-my6410.c:300: error: (near initialization for 'my6410_buttons') arch/arm/mach-s3c64xx/mach-my6410.c:301: error: field name not in record or union initializer arch/arm/mach-s3c64xx/mach-my6410.c:301: error: (near initialization for 'my6410_buttons') arch/arm/mach-s3c64xx/mach-my6410.c:302: error: field name not in record or union initializer arch/arm/mach-s3c64xx/mach-my6410.c:302: error: (near initialization for 'my6410_buttons') arch/arm/mach-s3c64xx/mach-my6410.c:303: error: field name not in record or union initializer arch/arm/mach-s3c64xx/mach-my6410.c:303: error: (near initialization for 'my6410_buttons') arch/arm/mach-s3c64xx/mach-my6410.c:304: error: field name not in record or union initialize ……………….. ……………………… …………………………………… 可以看出这个错误提示的意思是没有找到定义的数组,然后其他的就引起一连串的错误,解决的办法很简单就是把 #include <linux/gpio_keys.h> 这个头文件添加进去就可以了。       今天已经就做这么多吧,人都快累垮了。。。。。。明天继续。。。。。。 LCD驱动移植 向mach-my6410.c里面填入相应的平台信息: static struct s3c_fb_pd_win my6410_fb_win0 = {     /* this is to ensure we use win0 */     .win_mode    = {         .left_margin    = 2,         .right_margin    = 2,         .upper_margin    = 2,         .lower_margin    = 2,         .hsync_len    = 41,         .vsync_len    = 10,         .xres        = 480,         .yres        = 272,     },     .max_bpp    = 32,     .default_bpp    = 16, }; pixclock = 1000000 / DCLK = 1000000 / 9 = 111111 left_margin = Thb = 2 right_margin = Thf = 2 hsync_len = Thp = 41 upper_margin = Tvb = 2 lower_margin = Tvf = 2 vsync_len = Tvp = 10 xres = Thd = 480 Yres = Tvd = 272 static struct map_desc my6410_iodesc[] = {     {         /* LCD support */         .virtual = (unsigned long)S3C_VA_LCD,         .pfn = __phys_to_pfn(S3C_PA_FB),         .length = SZ_16K,         .type = MT_DEVICE,     }, }; 然后将28内核中的drviers/video/samsung拷贝到drviers/video/目录下 修改drviers/video/的Kconfig文件,在文件中加入 source "drivers/video/samsung/Kconfig" 修改修改drviers/video/的Makefie文件,再最后一行添加: obj-$(CONFIG_FB_S3C_EXT) += samsung/ 在arch/arm/plat-samsung/include/plat/map-base.h里面添加      #define S3C_VA_LCD S3C_ADDR(0x01100000)     /* LCD */ 在include/generated/atuoconfig.h里面添加 #define CONFIG_FB_S3C_EXT_NUM 4 把drivers/video/samsung/s3cfb_fimd4x.c里面的 第1417行: s3c6410_pm_do_save(s3c_lcd_save, ARRAY_SIZE(s3c_lcd_save)); 改成 s3c_pm_do_save(s3c_lcd_save, ARRAY_SIZE(s3c_lcd_save)); 第1438行 s3c6410_pm_do_restore(s3c_lcd_save, ARRAY_SIZE(s3c_lcd_save)); 改成 s3c_pm_do_restore(s3c_lcd_save, ARRAY_SIZE(s3c_lcd_save)); 配置内核: Device Drivers ---> Graphics support ---> <*> Support for frame buffer devices ---> (里面的都空选) <*> Support for frame buffer devices ---> [ ] Backlight & LCD device support ---> <*> S3C Framebuffer Support (eXtended)(修改Kconfig之后才有这个选) Select LCD Type (4.3 inch 480x272 TFT LCD) ---> (X) 4.3 inch 480x272 TFT LCD <*> Advanced options for S3C Framebuffer Select BPP(Bits Per Pixel) (16 BPP) ---> (4) Number of Framebuffers [ ] Enable Virtual Screen [*] Enable Double Buffering Console display driver support ---> <*> Framebuffer Console support [*] Bootup logo --->(显示小企鹅) [*] Standard 224-color Linux logo 如果驱动移植成功内核启动的时候会打印一下信息: S3C_LCD clock got enabled :: 133.000 Mhz LCD TYPE :: LTE480WV will be initialized Window[0] - FB1: map_video_memory: clear ffd80000:0007f800 FB1: map_video_memory: dma=5f900000 cpu=ffd80000 size=0007f800 Window[0] - FB2: map_video_memory: clear ffdbfc00:0003fc00 FB2: map_video_memory: dma=5f93fc00 cpu=ffdbfc00 size=0003fc00 Console: switching to colour frame buffer device 60x34 fb0: s3cfb frame buffer device Window[1] - FB1: map_video_memory: clear ffd00000:0007f800 FB1: map_video_memory: dma=5f980000 cpu=ffd00000 size=0007f800 Window[1] - FB2: map_video_memory: clear ffd3fc00:0003fc00 FB2: map_video_memory: dma=5f9bfc00 cpu=ffd3fc00 size=0003fc00 fb1: s3cfb frame buffer device Window[2] - FB1: map_video_memory: clear ffcc0000:0003fc00 FB1: map_video_memory: dma=5fa00000 cpu=ffcc0000 size=0003fc00 fb2: s3cfb frame buffer device Window[3] - FB1: map_video_memory: clear ffc80000:0003fc00 FB1: map_video_memory: dma=5fa40000 cpu=ffc80000 size=0003fc00 fb3: s3cfb frame buffer device 在LCD还会显示小企鹅: 相应的驱动程序都在 drviers/video/Samsung/s3cfb.c目录下     今天就为这驱动搞了一天,其实早就可以成功的,TMMD的不知道是不是手贱还是怎么的, 竟然把System Type ---> [* ] SMDK6400 选上了,最后系统一直打印都是SMDK6400的信息。幸好我靠 printk(KERN_INFO "DEBUG\n\n\n\n"); 找到了原因。 以后有时间好好对LCD驱动做一下分析。 DM9000网卡驱动移植 Linux内核里面已经 支持了dm9000的网卡驱动,所以驱动程序我们不需要写了,只需要添加 相应的平台信息。在linux-3.3.5/arch/arm/mach-s3c64xx/mach-my6410.c里面添加都文件#include <linux/dm9000.h> 在linux-3.3.5/arch/arm/mach-s3c64xx/mach-my6410.c里面添加以下平台信息: #define S3C64XX_PA_DM9000    (0x18000000) #define S3C64XX_SZ_DM9000    SZ_1M static struct resource my6410_dm9000_resources[] = { [0] = { .start= S3C64XX_PA_DM9000, .end= S3C64XX_PA_DM9000 + 3, .flags= IORESOURCE_MEM, }, [1] = { .start= S3C64XX_PA_DM9000 + 4, .end= S3C64XX_PA_DM9000 + S3C64XX_SZ_DM9000 - 1, .flags= IORESOURCE_MEM, }, [2] = { .start= IRQ_EINT(7), .end= IRQ_EINT(7), .flags= IORESOURCE_IRQ | IRQF_TRIGGER_HIGH, }, };   static struct dm9000_plat_data my6410_dm9000_platdata = { .flags= DM9000_PLATF_16BITONLY, .dev_addr= { 0x08, 0x90, 0x00, 0xa0, 0x90, 0x90 }, };   static struct platform_device my6410_device_dm9000 = { .name= "dm9000", .id= 0, .num_resources= ARRAY_SIZE(my6410_dm9000_resources), .resource= my6410_dm9000_resources, .dev= { .platform_data = &my6410_dm9000_platdata, } }; 然后在static struct platform_device *my6410_devices[] __initdata =里面添加 &my6410_device_dm9000, 配置内核,这里网络配置的选项很多,但都要根据实际选对:     出现的问题及解决方案: 编译的时候出现: SYSMAP System.map SYSMAP .tmp_System.map Inconsistent kallsyms data This is a bug - please report about it Try make KALLSYMS_EXTRA_PASS=1 as a workaround make: *** [vmlinux] 错误 1 这样的错误没有任何提示,经过总结,我发现这样的错误出现的原因就是内核中有些设备没有配置但是在BSP里面却定义了,或者是 BSP里面定义了,但是内核没有配置。 解决方法是把static struct platform_device *my6410_devices[] __initdata里面一些三星的东西去掉,其实如果从一个空模版移植是不会出现这类问题的,这里我还是有些偷懒。修改以后的内容如下: static struct platform_device *my6410_devices[] __initdata = { #ifdef CONFIG_SMDK6410_SD_CH0 &s3c_device_hsmmc0, #endif &my6410_device_button, &my6410_device_led, &my6410_device_dm9000, #ifdef CONFIG_SMDK6410_SD_CH1 &s3c_device_hsmmc1, #endif &s3c_device_i2c0, //&s3c_device_i2c1, &s3c_device_fb, &s3c_device_ohci, &s3c_device_usb_hsotg, &samsung_asoc_dma, //&s3c64xx_device_iisv4, //&samsung_device_keypad,   #ifdef CONFIG_REGULATOR //&my6410_b_pwr_5v, #endif //&my6410_lcd_powerdev,   //&my6410_smsc911x, //&s3c_device_adc, //&s3c_device_cfcon, &s3c_device_rtc, &s3c_device_ts, //&s3c_device_wdt, };

arm-linux- ARCH ?= arm Make menuconfig配置busybox Busybox Settings --->     Build Options ---> Installation Options ("make install" behavior) ---> Busybox Library Tuning ---> 编译busybox执行 Make install 这时候会提示一个错误提示说: miscutils/ubi_tools.c:63:26: error: mtd/ubi-user.h: No such file or directory miscutils/ubi_tools.c: In function 'ubi_tools_main': miscutils/ubi_tools.c:133: error: 'UBI_DEV_NUM_AUTO'

出现这么多的错误,核心问题就是出现在miscutils/ubi_tools.c:63:26: error: mtd/ubi-user.h: No such file or directory这个上面,无法找到mtd/ubi-user.h头文件,查阅了相关资料后,原来这是一个Linux下新支持的UBI文件系统,需要手 工加入。从Linux3.3.5的include\mtd\ubi-user.h拷贝到busybox下的include\mtd下,如果 busybox下的include没有mtd文件夹,那就先建立一个mtd文件夹,然后复制了。这样做了之后,编译就OK了。出现下面的信息就说明编译成 功了。 建立根目录,这里我们直接写一个脚本程序运create_rootfs.sh行就可以了,脚本的内容如下: #!/bin/sh echo "------Create rootfs directons start...--------" mkdir rootfs  cd rootfs  echo "--------Create root,dev....----------" mkdir root dev etc boot tmp var sys proc lib mnt home usr mkdir etc/init.d etc/rc.d etc/sysconfig mkdir usr/sbin usr/bin usr/lib usr/modules echo "make node in dev/console dev/null" mknod -m 600 dev/console c 5 1 mknod -m 600 dev/null c 1 3 mkdir mnt/etc mnt/jffs2 mnt/yaffs mnt/data mnt/temp mkdir var/lib var/lock var/run var/tmp chmod 777 tmp chmod 777 var/tmp echo "-------make direction done---------" 运行脚本执行: ./ create_rootfs.sh ls rootfs boot  dev  etc  home  lib  mnt  proc  root  sys  tmp  usr  var etc/inittab 系统init进程配置文件,并更改权限 chmod +x inittab ::sysinit:/etc/init.d/rcS ::askfirst:-/bin/sh #没有这就不行,就不能打开console控制台。 ::restart:/sbin/init ::ctrlaltdel:/sbin/reboot ::shutdown:/bin/umount -a -r ::shutdown:/sbin/swapoff –a etc/init.d/rcS系统启动加载项文件,并更改权限chmod +x etc/init.d/rcS #!/bin/sh PATH=/sbin:/bin:/usr/sbin:/usr/bin runlevel=S

LOGNAME=$USER PS1="[\u@\h \w]#"  #\w 目录将显示全路径 PATH=$PATH HOSTNAME= '/bin/hostname'  alias cls="clear" export USER LOGNAME PS1 PATH  /etc/passwd shadow 用户文件以及密码 把主机的passwd shadow 文件拷贝到/etc下 # cp /etc/passwd  rootfs/etc # cp /etc/group rootfs/etc # cp /etc/shadow rootfs/etc etc/sysconfig/HOSTNAME的内容为你自己的名字即可,内容为"Pillar" gedit /etc/sysconfig/HOSTNAME  然后键入 Pillar 在busybox目录下会看见 _install目录,里面有/bin /sbin l inuxr三个文件 将这三个目录或文件拷到第一步所建的rootfs文件夹下。 #cp bin/ sbin/ linuxrc /home/rootfs -ra  在把_install目录的usr里面的bin,sbin也按照刚才的方法拷贝到rootfs目录下 切记一定要带上-a的参数,因为bin目录里大部分都是链接,如果不带-a的参数,拷过去之后会做相应的复制,不再是链接的形式 将交叉编译器下的lib下的库拷贝到lib文件夹下 cp /usr/local/arm/4.2.2-eabi/lib/* ./ 这时候rootfs目录下的tree应该是这个样子的: . ├── bin │   ├── addgroup -> busybox │   ├──

successfully : 12 bits input: S3C TouchScreen as /devices/virtual/input/input0                                                             移植Qt4.8.1 tslib移植及测试 在采用触摸屏的移动终端中,触摸屏性能的调试是个重要问题之一,因为电磁噪声的缘故,触摸屏容易存在点击不准确、有抖动等问题。   Tslib是一个开源的程序,能够为触摸屏驱动获得的采样提供诸如滤波、去抖、校准等功能,通常作为触摸屏驱动的适配层,为上层的应用提供了一个统一的接口。 在https://github.com/kergoth/tslib下载了最新的tslib 为虚拟机里的Linux系统安装工具: sudo apt-get install autoconf sudo apt-get install automake sudo apt-get install libtool 解压后编译 mv xxx(解压后名字) tslib  //名字改为tslib  cd tslib ./autogen.sh  mkdir tmp echo "ac_cv_func_malloc_0_nonnull=yes" >arm-linux.cache ./configure --host=arm-linux --cache-file=arm-linux.cache --prefix=$(pwd)/tmp make make install 打开tmp目录,里面有四个文件夹,分别是bin、etc、include、lib。将etc目录下的ts.conf里的第2行去掉注释。即: # module_raw input 改为: module_raw input 将bin/etc/lib目录下的文件及连接拷贝到文件系统下对应同名目录。include目录估计是编译应用程序时用的,在此可以不使用 在文件系统的/etc/profile后面添加以下环节变量: export USER LOGNAME PS1 PATH export TSLIB_TSDEVICE=/dev/event0 export TSLIB_CALIBFILE=/etc/pointercal export TSLIB_CONFFILE=/etc/ts.conf export TSLIB_PLUGINDIR=/lib/ts export TSLIB_CONSOLEDEVICE=none export TSLIB_FBDEVICE=/dev/fb0 重启开发板执行env命令,查看是否有以下环境变量: TSLIB_TSDEVICE=/dev/event0 USER=id -un HOME=/ TSLIB_FBDEVICE=/dev/fb0 PS1=[\u@\h \w]# TSLIB_PLUGINDIR=/lib/ts TSLIB_CONSOLEDEVICE=none LOGNAME=id -un TERM=vt102 PATH=/sbin:/usr/sbin:/bin:/usr/bin TSLIB_CONFFILE=/etc/ts.conf SHELL=/bin/sh PWD=/ TSLIB_CALIBFILE=/etc/pointercal 这个TSLIB_TSDEVICE=/dev/event0环境变量所指的位置很重要,错了就会出现 ts_open:ts_open no such file or directory这样的错误 执行ts_test命令,就会出现以下画面: 如果出现-/bin/sh: ts_test: not found这样的错误,说明交叉编译器里面的库没有拷贝进来,对于交叉编译器4.3.2是arm-none-linux-gnueabi/libc/lib 执行ts_calibrate命令就会出现以下画面: 移植qt-everywhere-opensource-src-4.8.1 解压qt-everywhere-opensource-src-4.8.1,在解压目录下我们自己先写一个autu.sh的脚本,脚本内容如下: ./configure -prefix /usr/local/Qt \ > -no-qt3support \ > -qt-zlib \ > -qt-libtiff \ > -qt-libpng \ > -qt-libmng \ > -qt-libjpeg \ > -make libs \ > -nomake examples \ (因为这个是arm版本,所以编译出来的程序只能在arm开发板上运行,编译时把这些给去掉,加快编译过程) > -nomake demos \ > -nomake docs \ > -no-nis \ > -no-cups \ > -no-iconv \ > -xplatform qws/linux-arm-g++ \ >

-qt-kbd-tty \ > -qt-mouse-pc \ > -no-glib \ > -qt-mouse-tslib -I /usr/local/Tslib/include \ -L /usr/local/tslib/lib make make install 至于这些选项的含义搭建可以直接到Qt官网上去查。 如果最后出现这个错误: ./autoconfig.sh: 行 37: -I/usr/local/tslib/include: 没有那个文件或目录最后直接用 export QMAKE_INCDIR=/usr/local/tslib/include/          export QMAKE_LIBDIR=/usr/local/tslib/lib/ 这样的设置经验证好像只有在arm-linux-gcc-4.4.1的版本中可行 在rootfs/usr/下新建一个文件为qtlib,将/usr/local/Qt/lib下的所有文件复制到qtlib目录下 设置环境变量:将rootfs/etc/profile里面添加一下环境变量: export QTDIR=/usr/qilib export QPEDIR=$QTDIR export QT_PLUGIN_PATH=/usr/qilib export T_ROOT=/usr/tslib export PATH=$QTDIR/:$PATH export QWS_MOUSE_PROTO=Tslib:/dev/event0 export LD_LIBRARY_PATH=$T_ROOT/lib:$QTDIR export QT_QWS_FONTDIR=/usr/qilib/fonts 修改启动设置,修改rootfs/etc/init.d/rcS,添加一下内容: source /etc/profile echo "" > /dev/tty1 echo "" > /dev/tty1 echo "Designer is Pillar !" > /dev/tty1 echo "Staring touch calibrate..." > /dev/tty1 echo "" > /etc/tty1 sleep 1 /bin/ts_calibrate & #开机运行ts_calibrate 到这里qt-everywhere-opensource-src-4.8.1就移植完了   嵌入式Qt开发环境搭建 下载Qt集成开发环境 http://qt.nokia.com/downloads/sdk-linux-x11-32bit-cpp-offline 执行一下命令安装:     chmod u+x Qt_SDK_Lin32_offline_v1_2_en.run ./Qt_SDK_Lin32_offline_v1_2_en.run 配置集成 开发环境 新建工程,然后: 最后可以用file 命令查看文件属性 将文件拷贝到rootfs目录下: 执行:./books 就可以运行。 修改启动文件让开机就运行改文件,在rootf/etc/init.d/rcS文件中添加以下内容: if [ -f "$TSLIB_CALIBFILE" ]; then books -qws& else ts_calibrate 运行应用程序常见文件及错误分析: Cannot create semaphore /tmp/qtembedded-root/QtEmbedded-0 这是说明系统禁止了锁,可以在内核配置的第一个 generated配置里面找到: [*] System V IPC 选上它,重新编译,再次烧入内核 Illegal instruction 库添加错误,一定要正确的添加交叉编译器的库和qt-everywhere-opensource-src-4.8.1编译生成的库 Segmentation fault 编译应用程序的编译器不对,推荐从内核到文件系统都用同一个交叉编译器,经验证 arm-linux-gcc-4.4.1这个编译器稳定性不错         这两天就搞了和Qt相关的这些事,错不多所有的的东西都是在5天的时间内搞定的,今天早上是6点钟起来写文档,不知道什么时候,我自己变得这么疯狂。 还有很多问题没有解决: 本来想搞个opia的,比如Qt Extended,其实就是Qtopia.我搞的时候才发现: Qt Extended是由Nokia的子公司Qt Software(前称Trolltech)所开发。2009年3月3日,Qt Software宣布Qt Extended不再继续作为独立产品而开发,部份功能整合进Qt Framework。别人都终止了,所以就不提供源码了,网上有很多源码可以都可以下载,但是大多数都是别人改过的。飞凌的提供的源码也被他改的乱七八糟,我死都编译不过去,既然连源码都找不到,我移植就没有办法下手了。 还有一个交叉编译器的库的问题。仔细一点你会发现我用的arm-linux-gcc-4.4.1里面有好的的lib还有好的名字是重复的。大家可以看看这篇文章对交叉编译器的理解http://wenku.baidu.com/view/45f3b6f29e31433239689382.html
