如果不想被坑卓坑， 又想比较好地使用摄像头，可以使用主线Uboot加Bsp内核方案， 系统配置为fex文件配置。
主线uboot： https://github.com/Lichee-Pi/u-boot
bsp内核： http://pan.baidu.com/s/1eRJrViy
一、安装交叉编译环境
交叉编译环境跟uboot使用的一样。
参考：arm-linux-gnueabihf 交叉编译工具链安装
二、下载bsp内核源码
bsp内核： http://pan.baidu.com/s/1eRJrViy
linux-3.4是bsp内核源码。
三、修改顶层Makefile
在内核根目录下的Makefile195行修改默认编译器，可以直接用make编译：
# ARCH ?= $(SUBARCH)
# CROSS_COMPILE ?= $(CONFIG_CROSS_COMPILE:"%"=%)
ARCH ?= arm
CROSS_COMPILE ?= arm-linux-gnueabihf-
四、编译
lichee_BSP_config配置修改了内核支持网口 支持ext4文件系统
cd linux-3.4
cp lichee_BSP_config .config
make uImage -j16
make -j16 INSTALL_MOD_PATH=out modules # 编译出模块
make -j16 INSTALL_MOD_PATH=out modules_install # 安装模块
uImage 在 arch/arm/boot/uImage目录
五、TF卡烧录
准备好之前生成的boot.scr和script.bin
参考：u-boot传参(boot.scr)和参数配置(script.bin)文件
# 查询挂载名
df -h
# 拷贝到第一分区（32M卷）
cp uImage boot.scr script.bin /media/pjw/43EE-E439
六、输出LOG：
