TQIMAX6q调试笔记二：linux与uboot的编译

一.按照《TQIMX6环境搭建》，成功安装ubuntu开发环境。

二.按照《TQIMX6_COREC编译手册》，成功安装交叉编译器。

三.按照《TQIMX6_COREC编译手册》，编译源码：

1.成功编译uboot，并烧录板子，打印如下信息：

U-Boot 2015.04 (Sep 21 2017 - 11:05:26)

CPU:   Freescale i.MX6Q rev1.5 at 792 MHz

CPU:   Temperature 33 C

2.成功编译kernel，但烧录板子后，kernel启动失败，打印如下信息：

   Using Device Tree in place at 18000000, end 1800ddee

Starting kernel ...

可能原因：编译库文件版本可能不对，需要更新库。

解决方案：创建ubuntu_env_install.sh可执行文件，在文件中加入以下信息：

apt-get update

add-apt-repository ppa:ubuntu-toolchain-r/test

mv -f /usr/bin/g++ /usr/bin/bak_g++

ln -s /usr/bin/gcc-4.4 /usr/bin/gcc

ln -s /usr/bin/g++-4.4 /usr/bin/g++

保存后，执行脚本，在编译烧录，成功！！！！打印信息如下：
