《CentOS 6.3 64-bit Host Building i.MX6Q-SDB Linux L3.0.35_12.09.01.01_GA_Source》
Introduction
The SABRE Board for Smart Devices Based on the i.MX 6 Series is an evalutaion board featuring the i.MX6 Quad Core Cortex-A9 processor. Freescale ported the Linux Operating System (as of this writing version 3.0.35) and the Board Support Package (BSP) containing
the Linux Kernel, build system called LTIB, GCC compiler tools, boot loader, u-boot, and root file system is available for download, install, and build.
LTIB is a perl script and is the acroynm for Linux Target Image Builder.
This document describes setting up a CentOS 6.3 64-bit host in a virtual machine for using the BSP and running the images on i.MX6Q-SDB evaluation board.

Document Conventions
Bold lines are Linux commands and edits run on CentOS.
The ‘$‘ indicates running the command as a regular user
The ‘#‘ indicates running the command as root user.
CentOS Host Setup
For this example a virtual machine is used, however a dedicated PC running only CentOS linux could be used.
1. Add user login to sudo‘ers file (给普通用户添加root权限)
Login as user root and run the visudo command
# visudo
Add the following line and save the file:
user ALL=(ALL) ALL
2. Update the system packages:
$ sudo yum udpate
3. Install package for "ltib" operations: （安装必备的软件）
$ sudo yum install make gcc gcc-c++ kernel-devel bison libuuid-devel ncurses-devel zlib-devel lzo-devel intltool libtool tcl rpm-build
perl-ExtUtils-MakeMaker ld-linux.so.2 zlib-1.2.3-27.el6.i686
4. Update sudo‘ers file for supporting ltib rpm
$ sudo visudo
Add the following line and save the file:
user ALL=NOPASSWD: /bin/rpm,/opt/freescale/ltib/usr/bin/rpm
在最后添加 这一行，user替换成你的username。
Install BSP
The sources are in a tar gziped archive file which is downloaded from http://freescale.com/sabresdb,
selecting the Software & Tools tab then expanding Run-time Software in the middle of the page. A free login is required for download which can be registered for by selecting the Login at the top right of the freescale.com page.
Once downloaded, verify the md5 checksum (see references above for the value).
$ mkdir ~/imx6
$ tar -zxf L3.0.35_12.09.01.01_GA_source.tar.gz -C ~/imx6
$ cd ~/imx6/*source
$ ./install
Installation complete, your ltib installation has been placed in y/ltib, to complete the installation: cd /ltib ./ltib
Read and accept the licensing information.
Choose a directory to install too, for this example entered .. which is the parent directory.
Build the i.MX6Q SDB
$ cd ~/imx6/ltib
$ ./ltib
./ltib Installing host support packages. This only needs to be done once per host, but may take up to an hour to complete ... If an error occurs, a log file with the full output may be found in: /home/your name/L3.0.35_4.1.0_130816_source/ltib/host_config.log

After some time (depends on how fast your host computer is) the menuing system is shown which allows you to select build configurations.
The second screen selects the development platform which is imx6q for the SDB. For this example the Min profile is chosen which is the default. Use the arrow keys to move and the enter key to select. The space bar selects/deselects an entry.
Use the right arrow key to move to <Exit> and press the enter key. The save dialog box is presented, save. The next menu is the iMX6x Base Boards which leaving all as default except for the U-boot board selection which is mx6q_sabresd for the SDB. Save and
exit.
Images
When ltib completes, the images are found in <ltib>/rootfs/boot.
Bootloader = u-boot.bin
Linux Kernel = uImage
File system = </ltib>/rootfs
