如果不想被坑卓坑， 又想比較好地使用攝像頭，可以使用主線Uboot加Bsp內核方案， 系統配置為fex檔案配置，
主線uboot： https://github.com/Lichee-Pi/u-boot
bsp內核： http://pan.baidu.com/s/1eRJrViy

一、安裝交叉編譯環境

交叉編譯環境跟uboot使用的一樣，
參考：arm-linux-gnueabihf 交叉編譯工具鏈安裝

二、下載bsp內核原始碼

bsp內核： http://pan.baidu.com/s/1eRJrViy
linux-3.4是bsp內核原始碼，

三、修改頂層Makefile

在內核根目錄下的Makefile195行修改默認編譯器，可以直接用make編譯：

# ARCH		?= $(SUBARCH)
# CROSS_COMPILE	?= $(CONFIG_CROSS_COMPILE:"%"=%)
ARCH		?= arm
CROSS_COMPILE	?= arm-linux-gnueabihf-

四、編譯

lichee_BSP_config配置修改了內核支持網口 支持ext4檔案系統

cd linux-3.4
cp lichee_BSP_config .config
make uImage -j16
make -j16 INSTALL_MOD_PATH=out modules			# 編譯出模塊
make -j16 INSTALL_MOD_PATH=out modules_install	# 安裝模塊

uImage 在 arch/arm/boot/uImage目錄

五、TF卡燒錄

準備好之前生成的boot.scr和script.bin
參考：u-boot傳參(boot.scr)和引數配置(script.bin)檔案

# 查詢掛載名
df -h
# 拷貝到第一磁區（32M卷）
cp uImage boot.scr script.bin /media/pjw/43EE-E439

六、輸出LOG：
