今天听了宋宝华(http://www.embedu.org/lecture/index.htm)的讲座,一下子恍然大悟,我必须做点什么。。。。。。

Linux 3.3.5系统移植

  1. 将arch/arm/mach-s3c6410/下的,mach-smdk6410.c cp为mach-my6410.c;
  2. 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 ifWATCHDOG

    select S3C64XX_SETUP_SDHCI

    select S3C64XX_SETUP_I2C1

    select S3C64XX_SETUP_IDE

    selectS3C64XX_SETUP_FB_24BPP

    select S3C64XX_SETUP_KEYPAD

    help

    Machine support for the PillarMY6410

  3. 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;

  1. 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

  2. 在当前目录的Makefile最后一行加上 obj-$(CONFIG_MACH_MY6410) +=mach-my6410.o
  3. 修改顶层的Makefile:

    ARCH ?= arm

    CROSS_COMPILE ?=/usr/local/arm/4.2.2-eabi/usr/bin/arm-linux-

  4. 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XX6410board这一项,保存退出;
  5. 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

  1. Linu内核下drivers/leds/leds­gpio.c实现了一个体系结构无关的GPIOLED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_datamy6410_gpio_led_pdata ={

    .num_leds =ARRAY_SIZE(my6410_leds),

    .leds =my6410_leds,

    };

    static struct platform_devicemy6410_device_led ={

    .name = "leds-gpio",

    .id = -1,

    .dev ={

    .platform_data =&my6410_gpio_led_pdata,

    },

    };

  2. 将&my6410_device_led添加到static struct platform_device*my6410_devices[] __initdata中。
  3. 配置内核:

    Device Drivers--->

    [*] LED Support--->

    <*> LED Support forGPIO 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

  1. 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_buttonmy6410_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_datamy6410_button_data ={

    .buttons =my6410_buttons,

    .nbuttons=ARRAY_SIZE(my6410_buttons),

    };

    static struct platform_devicemy6410_device_button = {

    .name ="gpio-keys",

    .id = -1,

    .dev = {

    .platform_data=&my6410_button_data,

    },

    };

  2. 将&my6410_device_button添加到static struct platform_device*my6410_devices[] __initdata中
  3. 配置linux内核

    Device Drivers--->

    Input device support--->

    [*] Keyboards--->

    <*> GPIOButtons

    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 hasincomplete element type

    arch/arm/mach-s3c64xx/mach-my6410.c:300: error: field name notin record or union initializer

    arch/arm/mach-s3c64xx/mach-my6410.c:300: error: (nearinitialization for 'my6410_buttons')

    arch/arm/mach-s3c64xx/mach-my6410.c:301: error: field name notin record or union initializer

    arch/arm/mach-s3c64xx/mach-my6410.c:301: error: (nearinitialization for 'my6410_buttons')

    arch/arm/mach-s3c64xx/mach-my6410.c:302: error: field name notin record or union initializer

    arch/arm/mach-s3c64xx/mach-my6410.c:302: error: (nearinitialization for 'my6410_buttons')

    arch/arm/mach-s3c64xx/mach-my6410.c:303: error: field name notin record or union initializer

    arch/arm/mach-s3c64xx/mach-my6410.c:303: error: (nearinitialization for 'my6410_buttons')

    arch/arm/mach-s3c64xx/mach-my6410.c:304: error: field name notin 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

    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

  1. 向mach-my6410.c里面填入相应的平台信息:

    static struct s3c_fb_pd_winmy6410_fb_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[]= {

{

.virtual =(unsigned long)S3C_VA_LCD,

.pfn =__phys_to_pfn(S3C_PA_FB),

.length =SZ_16K,

.type =MT_DEVICE,

},

};

  1. 然后将28内核中的drviers/video/samsung拷贝到drviers/video/目录下
  2. 修改drviers/video/的Kconfig文件,在文件中加入

    source "drivers/video/samsung/Kconfig"

  3. 修改修改drviers/video/的Makefie文件,再最后一行添加:

    obj-$(CONFIG_FB_S3C_EXT) += samsung/

  4. 在arch/arm/plat-samsung/include/plat/map-base.h里面添加

#define S3C_VA_LCD S3C_ADDR(0x01100000)

  1. 在include/generated/atuoconfig.h里面添加

    #define CONFIG_FB_S3C_EXT_NUM 4

  2. 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));

  1. 配置内核:

    Device Drivers--->

Graphics support--->

<*> Support for framebuffer devices ---> (里面的都空选)

<*> Support for framebuffer devices --->

[ ] Backlight & LCDdevice support --->

<*> S3C FramebufferSupport (eXtended)(修改Kconfig之后才有这个选)

Select LCD Type (4.3 inch480x272 TFT LCD) --->

(X) 4.3 inch 480x272 TFTLCD

<*> Advanced optionsfor S3C Framebuffer

Select BPP(Bits Per Pixel)(16 BPP) --->

(4) Number ofFramebuffers

[ ] Enable VirtualScreen

[*] Enable DoubleBuffering

Console display driversupport --->

<*> FramebufferConsole support

[*] Bootup logo--->(显示小企鹅)

[*] Standard 224-color Linuxlogo

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

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 "DEBUGnnnn");

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

  1. 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
  2. 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_datamy6410_dm9000_platdata = {

.flags= DM9000_PLATF_16BITONLY,

.dev_addr= { 0x08, 0x90, 0x00, 0xa0,0x90, 0x90 },

};

static struct platform_devicemy6410_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,

  1. 配置内核,这里网络配置的选项很多,但都要根据实际选对:

  1. 出现的问题及解决方案:
    1. 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,

};

  1. 启动过程中出现这样的问题:

smsc911x: failed to claim resource0(这个提示原来在这儿我怎么没有发现)

出现这个这个错误的原因根据提示可以知道那个玩意儿没有得到资源。

原来它在arch/arm/mach-s3c64xx/include/mach/map.h 被这样定义

#define S3C64XX_PA_XM0CSN1 (18000000)

这个刚好我我们定义的DM9000的物理地址相同

所以就冲突了。解决方法很简单,就是把

static struct platform_device *my6410_devices[]__initdata里面的

//&my6410_smsc911x,注释掉。

搭建NFS网络文件系统

  1. 制作文件系统的工具就是传说中的瑞士军刀busybox在他的官网http://www.busybox.net下载最新的版本为busybox-1.20.0
  2. 修改busybox的makefile:

    CROSS_COMPILE ?= arm-linux-

    ARCH ?= arm

  3. Make menuconfig配置busybox

    Busybox Settings --->

    Build Options --->

    Installation Options ("make install" behavior) --->

    Busybox Library Tuning --->

  4. 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 fileor directory
    miscutils/ubi_tools.c: In function 'ubi_tools_main':
    miscutils/ubi_tools.c:133: error: 'UBI_DEV_NUM_AUTO' undeclared(first use in this function)
    miscutils/ubi_tools.c:133: error: (Each undeclared identifier isreported only once
    miscutils/ubi_tools.c:133: error: for each function it appearsin.)
    miscutils/ubi_tools.c:134: error: 'UBI_VOL_NUM_AUTO' undeclared(first use in this function)
    miscutils/ubi_tools.c:153: error: storage size of 'req' isn'tknown
    miscutils/ubi_tools.c:161: error: 'UBI_IOCATT' undeclared (firstuse in this function)
    miscutils/ubi_tools.c:153: warning: unused variable 'req'

make[1]: *** [miscutils/ubi_tools.o] 错误 1
make: *** [miscutils] 错误 2

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 ordirectory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includemtdubi-user.h拷贝到busybox下的includemtd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。

  1. 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

  2. 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

  3. 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
    prevlevel=N
    umask 022
    export PATH runlevel prevlevel
    mount -a
    mkdir /dev/pts
    mount -t devpts devpts /dev/pts #用于telnet登录时使用

    echo /sbin/mdev > /proc/sys/kernel/hotplug
    mdev -s
    mkdir -p /var/lock
    /bin/hostname -F /etc/sysconfig/HOSTNAME

  4. etc/fstab 系统挂载文件系统列表文件

    #device mount-point type option dump fsck order
    proc /proc proc defaults 0 0
    sysfs /sys sysfs defaults 0 0
    mdev /dev ramfs defaults 0 0
    none /var ramfs defaults 0 0
    none /tmp ramfs defaults 0 0

  5. etc/profile用户环境配置文件

    # Ash profile
    # vim: syntax= sh
    # No core file by defaults
    非常详细的ok6410的linux系统移植《转载》 ok6410 linux移植
    # ulimit - S - c 0> / dev/ null 2> & 1

    USER="id -un"
    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

  6. /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

  7. 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

  8. 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

    //#ifdef CONFIG_PLAT_S3C24XX

    //#endif

    //#endif

  9. 在arch/arm/plat-samsung/include/plat/regs-adc.h的后面添加以下代码:

    #define S3C_ADCREG(x) (x)

    #define S3C_ADCCON S3C_ADCREG(0x00)

  10. 配置内核:

    System Type --->

    [*] ADC common driver support

Device Drivers --->

Input device support --->

[*] Touchscreens --->

<*> S3C touchscreen driver(只选这一个,其他的不要选)

<*> Event interface

  1. 如果触摸屏驱动没有问题的会就会出现以下驱动信息:

S3C Touchscreen driver, (c) 2008 Samsung Electronics

S3C TouchScreen got loadedsuccessfully : 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。

  1. 在https://github.com/kergoth/tslib下载了最新的tslib
  2. 为虚拟机里的Linux系统安装工具:

    sudoapt-get install autoconf

    sudoapt-get install automake

    sudoapt-get install libtool

  3. 解压后编译

    mv xxx(解压后名字) tslib //名字改为tslib

    cdtslib

    ./autogen.sh

    mkdirtmp

    echo"ac_cv_func_malloc_0_nonnull=yes">arm-linux.cache

    ./configure--host=arm-linux --cache-file=arm-linux.cache --prefix=$(pwd)/tmp

    make

    makeinstall

  4. 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_rawinput

    改为:

    module_rawinput

  5. 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
  6. 在文件系统的/etc/profile后面添加以下环节变量:

    export USER LOGNAME PS1PATH

    exportTSLIB_TSDEVICE=/dev/event0

    exportTSLIB_CALIBFILE=/etc/pointercal

    exportTSLIB_CONFFILE=/etc/ts.conf

    exportTSLIB_PLUGINDIR=/lib/ts

    exportTSLIB_CONSOLEDEVICE=none

    exportTSLIB_FBDEVICE=/dev/fb0

  7. 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

  8. 执行ts_test命令,就会出现以下画面:

    如果出现-/bin/sh: ts_test: notfound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

  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++
> -embedded arm
> -little-endian
> -qt-freetype
> -depths 8,16,24,32
> -qt-gfx-linuxfb
> -no-gfx-transformed
> -no-gfx-qvfb
> -no-gfx-vnc
> -no-gfx-multiscreen
> -qt-kbd-usb
> -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

  1. 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
  2. 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

  3. 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

  1. 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

  1. 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。

  1. 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

  2. 运行应用程序常见文件及错误分析:
    1. 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

    2. 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

    3. 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:

    1. 本来想搞个opia的,比如QtExtended,其实就是Qtopia.我搞的时候才发现:

      Qt Extended是由Nokia的子公司QtSoftware(前称Trolltech)所开发。2009年3月3日,Qt Software宣布QtExtended不再继续作为独立产品而开发,部份功能整合进QtFramework。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。

    2. 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
