v2.0_A20_android_source.tar.gz




这个源码包含cb2  和ct


进入lichee\linun3.4
$ make mrproper


$ cp arch/arm/configs/cubieboard2_config arch/arm/configs/cubieboard2_defconfig


$ $ make ARCH=arm cubieboard2_defconfig


进入lichee目录 $ ./build.sh -p sun7i_android


再回到android目录
$ source build/envsetup.sh


$ lunch


$ extract-bsp


$ make -j4


$ pack
如果切换CT 


进入lichee\linun3.4
$ make mrproper


$ cp arch/arm/configs/cubietruck_config   arch/arm/configs/cubietruck_defconfig


$ $ make ARCH=arm cubietruck_defconfig


进入lichee目录 $ ./build.sh -p sun7i_android




再回到android目录
$ source build/envsetup.sh


$ lunch


$ extract-bsp


$ make -j4


$ pack


错误问题是，直接在lichee目录下$ ./build.sh -p sun7i_android
结果是lichee/linux-3.4/arch/arm/configs/sun7ismp_android_defconfig默认配置文件，这个配置没有打开一些宏定义，导致cpu启动出错了




---<<<<问题1
sys_config_fex   ///---->>>machine             = "sugar-cubieboard2"   //此处注意   卡在FEL




-----<<<<问题2
