用buildroot编译文件系统 (MYZR-IMX6-EK200)

软件01

主机平台： UBUNTU14.04
硬件平台：明远智睿MY-IMX6-EK200
编译器:      gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz
buildroot版本：buildroot-2017.02.5.tar.bz2

1.解压
$ mkdir ~/IMX6/
$ tar xvf ~/IMX6/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz

$ mkdir ~/buildroot
$ cd ~/buildroot
$ tar jxvf  buildroot-2017.02.5.tar.bz2
$ cd buildroot-2017.02.5/

2.配置
$ make imx6q-sabresd_defconfig
$ make menuconfig

采用外部编译器gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz
Toolchain--->
设置Toolchain type为External toolchain
Toolchain为Custom toolchain
Toolchain path为/home/linyn/IMX6/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/
选择【*】Toolchain has C++ support?

主要注意External toolchain kernel headers series (3.1.x)这个选项的设置,选择编译工具的内核版本号,文件
   ~/IMX6/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/arm-linux-gnueabihf/libc/usr/include/linux/version.h
    保存有版本号(每个编译工具都有这个文件的),是十进制的,把它转换成16进制就可以看出来版本号是多少,如我的version.h是这样
   #define LINUX_VERSION_CODE 196865
    #define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))
    196609版本的16进制是0x30101,那版本号就是3.01.01,就是3.0.1了,所以这里选3.1.x
看图片“配置1”

System configuration--->
(myzr) System hostname  设置主机名
/dev management (Dynamic using devtmpfs + mdev)   kernel配置支持medv，系统也配置mdev
Run a getty (login prompt) after boot --->
(ttymxc0) TTY port               设置登陆串口
         Baudrate (115200)  --->       波特率

不编译kernel
Kernel--->
[] Linux Kernel  不选

不编译U-BOOT
Bootloaders --->
[] U-Boot          不选

$ make -j4              //用4个线程编译
结果看产生output/images/rootfs.tar
看图片“结果1”和“结果2”（结果2是没编译kernel报的错误不管）

最后修改一下rootfs里面的

vim etc/issue
Welcome to MY-IMX6-EK200

vim etc/profile

if [ "$PS1" ]; then
        if [ "`id -u`" -eq 0 ]; then
         export PS1='\u@\h:\w\# '
        else
         export PS1='\u@\h:\w\$ '
        fi
fi

最后压缩烧写进去，用root登陆，默认没密码

你好，只烧写我们编译的文件系统，其他的可以不烧写，应该是有一些目录没有
可以修改一下ucl2.xml文件只烧写文件系统，把其他的暂时屏蔽

您好，我没有找到buildroot这个文件夹

自己新建的

dengqiang2004

采用buildroot方式构建文件系统，但是运行Qt程序时，需要登录才能运行。那怎么不登录，开机后就可以运行Qt？
