本文介绍了如何在研一阶段初次接触并编译U-Boot、Linux内核以及buildroot根文件系统。通过使用`make ARCH=arm menuconfig`配置蓝牙等功能，并利用交叉编译工具链`arm-linux-gnueabihf-`，将编译过程的时间和输出记录到build.log中。最后使用`-j16`选项进行16线程并行编译，以加速构建过程。

make ARCH=arm menuconfig #add bluethooth, etc.
time make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- 2>&1 | tee build.log（指定交叉编译工具链 log写入文件
）
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16（-j16 16线程编译）
在这里插入图片描述

u-boot编译完成，linux内核编译完成，buildroot根文件系统编译完成
