我是参考 @qianhao 大神这个帖子: https://whycan.cn/t_682.html
6.编译内核
使用我提供的 lichee_BSP_config 说明一下 这里修改了内核支持网口 支持ext4文件系统 就直接给出我配置好的。
cd linux-3.4cp lichee_BSP_config .config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage -j16
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j16 INSTALL_MOD_PATH=out modules
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j16 INSTALL_MOD_PATH=out modules_install
这时 我们要用的 uImage 在 arch/arm/boot/uImage
