Embedded Linux学习笔记—TQE9_i.MX6Q LTIB环境配置

LTIB是FreeScale提供的一种在不同目标平台下用于开发和部署BSP（板级支持包）的开发工具，官方的介绍：http://savannah.nongnu.org/projects/ltib/

TQ官方给出的TQE9内核版本是3.0.35，对应LTIB版本是L3.0.35_4.1.0

首先要准备的有：

Ubuntu 12.04（Server或Desktop版皆可，笔者在虚拟机中虚拟了一个Ubuntu Server，然后在host中ssh登陆）

L3.0.35_4.1.0_130816_source.tar.gz（LTIB源码包），下载地址：https://cache.nxp.com/secured/bsps/L3.0.35_4.1.0_130816_source.tar.gz?__gda__=1461212255_108cda6b7f5b9052caa07c8b9e3b8c6e&fileExt=.gz

L3.0.35_4.1.0_doc.tar.gz（LTIB官方文档包，内有详细步骤说明，可选），下载地址：https://cache.nxp.com/secured/32bit/doc/support_info/L3.0.35_4.1.0_docs.tar.gz?__gda__=1461230000_c448aafd5ae78e9ea0d0f8e6c0d7807c&fileExt=.gz






安装LTIB

解压源码包

tar zxvf L3.0.35_4.1.0_130816_source.tar.gz

安装LTIB,自行选择安装目录，笔者选择为 ~/EmbeddedLinux/L3.0.35_4.10

cd L3.0.35_4.1.0_130816_source
./install

编译LTIB

配置依赖环境

#!/bin/bash
# Install packages needed by LTIB
sudo aptitude -y install gettext libgtk2.0-dev rpm bison m4 libfreetype6-dev
sudo aptitude -y install libdbus-glib-1-dev liborbit2-dev intltool
sudo aptitude -y install ccache ncurses-dev zlib1g zlib1g-dev gcc g++ libtool
sudo aptitude -y install uuid-dev liblzo2-dev
sudo aptitude -y install tcl dpkg
sudo aptitude -y install asciidoc texlive-latex-base texinfo dblatex xutils-dev

# Packages required for 64-bit Ubuntu
# Do "uname -a" and see if the word "x86_64" shows up.
if uname -a|grep -sq 'x86_64'; then
sudo aptitude -y install ia32-libs libc6-dev-i386 lib32z1
fi

将上述代码保存为sh脚本，chmod加权限755运行即可

接下来安装官方提供的补丁

首先进入ltib文件夹

cd ~/EmbeddedLinux/L3.0.35_4.10/ltib

补丁文件代码

#!/usr/bin/env bash

# get the patch tarball and untar it
wget -O ubuntu-ltib-patch.tgz https://community.freescale.com/servlet/JiveServlet/downloadBody/93454 7fe8
-102-3-2834/ubuntu-ltib-patch.tgz
tar -xzvf ubuntu-ltib-patch.tgz

# execute the script which do the patching
ltibDir=`pwd`
cd ubuntu-ltib-patch
./install-patches.sh $ltibDir

将上述代码保存为sh脚本，chmod加权限755运行即可

添加sudo

sudo visudo

在文件末尾添加

username ALL = NOPASSWD: /usr/bin/rpm, /opt/freescale/ltib/usr/bin/rpm

Ctrl+X 保存 退出

检查系统路径/usr/include中是否有sys目录，若无，添加软链接

cd /usr/include
sudo ln -s i386-linux-gnu/sys sys

切换道LTIB安装目录，开始编译

cd ~/EmbeddedLinux/L3.0.35_4.10/ltib
./ltib

编译成功后会弹出mkconfig界面

第一个界面选择

Platform choice (Freescale iMX reference boards)  --->

第二个界面选择

Selection (imx6q)  --->

第三个界面选择

board (mx6q_sabresd)  --->

保存退出后自动开始编译u-boot，kernel等，成功后打印

Build Succeeded

编译过程中可能出现的问题

elftosb

将以上代码保存为：elftosb-types_h-fix.patch，并放在/opt/freescale/pkgs/目录

然后

nano ~/EmbeddedLinux/L3.0.35_4.10/ltib/dist/lfs-5.1/elftosb/elftosb.spec

在相应位置添代码（第3、7行）

..
Source : %{name}-%{version}-%{release}.tar.gz
Patch0 : elftosb-types_h-fix.patch
BuildRoot : %{_tmppath}/%{name}
...
%setup -n %{name}-%{version}-%{release}
%patch0 -p1
%Build
make
...

删除elftosb文件夹

sudo rm -rf /opt/freescale/ltib/usr/src/rpm/BUILD/elftosb-3.0.35-4.0.0

NOTE： ltib用一般用户编译，而CROSS_COMPILE的值没传过来，，，，增加一般用户的环境变量或在makefile添加CROSS_COMPILE的值

编辑base_libs.spec文件，注释两行代码

nano ~/EmbeddedLinux/L3.0.35_4.10/ltib/dist/lfs-5.1/base_libs/base_libs.spec

注释

...
perl -w -e '
# @ARGV = grep { `file $_` =~ m,ASCII C program text, } @ARGV;
# exit (0) unless @ARGV;
