3 u-boot编译
3.1 编译前的准备
创建编译工作目录
=====> Input:
mkdir ~/my-work/02_source/ -p
解压源码包到工作目录
=====> Input:
tar xf u-boot-2016.03-svn*.tar.bz2 -C ~/my-work/02_source/
3.2 编译u-boot目标文件
进入源码目录
=====> Input:
cd ~/my-work/02_source/u-boot-2016.03
生成目标开发板的 .config 文件
=====> Input:
make myimx6ek200-6q-1g_defconfig
=====> Output:
HOSTCC scripts/basic/fixdep
HOSTCC scripts/kconfig/conf.o
SHIPPED scripts/kconfig/zconf.tab.c
SHIPPED scripts/kconfig/zconf.lex.c
SHIPPED scripts/kconfig/zconf.hash.c
HOSTCC scripts/kconfig/zconf.tab.o
HOSTLD scripts/kconfig/conf
#
# configuration written to .config
#
【注意】：上面 make 后面的 myimx6ek200-6q-1g_defconfig 改为与开发板型号对应的配置文件。

Note: 如果有提示 “cc1: error”，通常是交叉编译工具的配置没生效，可以按前面 “交叉编译工具链安装” 中的 “source 工具链配置文件” 操作一次后再执行此步骤。
u-boot 目标文件
u-boot.imx 即目标文件。
3.3 编译u-boot环境变量脚本
=====> Input:
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "myzr bootscripts" -d board/myzr/bootscripts/myimx6a9_l3035_script.cmd my_environment.scr
=====> Output:
Image Name: myzr bootscripts
