1、搭建编译环境
tar -xvf CLFS-loongarch64-8.1-x86_64-cross-tools-gcc-glibc.tar.xz
sudo mv cross-tools /usr/local/loongson-gnu-toolchain-13.2
export PATH=${PATH}:/usr/local/loongson-gnu-toolchain-13.2/bin
source ~/.bashrc
验证loongarch64-unknown-linux-gnu-gcc --version
输出以下信息表示搭建完毕
loongarch64-unknown-linux-gnu-gcc (GCC) 13.2.0

2、编译u-boot
sudo apt install bison flex libssl-dev libncursesw5-dev
（1）编译其他2k0300板子（官方教程，不保证能用）
将u-boot-la.tar.gz拷贝进去
tar -zxvf u-boot-la.tar.gz
cd u-boot-la
sudo nano configs/loongson_2k0300_defconfig
修改CONFIG_SPI_FLASH_XTX=y
make CROSS_COMPILE=loongarch64-unknown-linux-gnu- loongson_2k0300_defconfig
make CROSS_COMPILE=loongarch64-unknown-linux-gnu-
（2）编译久久派plus
将u-boot-la-99pi-plus-master.zip拷贝进去
unzip u-boot-la-99pi-plus-master.zip
cd u-boot-la-99pi-plus-master
make CROSS_COMPILE=loongarch64-unknown-linux-gnu- loongson_2k0300_defconfig
make CROSS_COMPILE=loongarch64-unknown-linux-gnu-
编译完成后，目录下的u-boot-spl-gz.bin就是u-boot文件
3、编译buildroot
（1）环境准备
sudo apt install g++ cpio
将buildroot.tar.gz拷贝进去
tar -zxvf buildroot.tar.gz
cd buildroot
cp ./config_systemd .config
（2）配置交叉编译工具链
make ARCH=loongarch64 menuconfig
Toolchain path：修改为/usr/local/loongson-gnu-toolchain-13.2
Toolchain prefix：修改为$(ARCH)-unknown-linux-gnu
External toolchain gcc version：修改为13.x
External toolchain kernel headers series：修改为6.5.x
Toolchain has RPC support：输入n
然后选择save保存，并选择exit退出配置界面
（3）修改hostname主机名和欢迎语
System configuration --->System hostname
System configuration --->System banner
（4）添加常用工具
Target packages --->Filesystem and flash utilities --->dosfstools、mkfs.fat、
Target packages --->Networking applications ---> net-tools、openssh
Shell and utilities --->bash、sudo
Target packages --->System tools --->htop、tar
Target packages --->Compressors and decompressors --->zip、unzip
Text editors and viewers --->nano
Target packages --->Interpreter languages and scripting --->External python modules --->python-pip
Target packages --->Interpreter languages and scripting --->python3 module format to install --->.py sources and .pyc compiled
Target packages --->Libraries --->Networking --->libcurl
（5）编译文件系统
输入su进入超级管理员，然后输入密码
make
执行完后会在output/images文件夹下生成rootfs.cpio rootfs.tar rootfs.tar.gz三个文件
如果编译后的系统，pip3执行一直提示缺少zlib，可能需要先清除一下之前的缓存make python3-dirclean，然后再执行make
4、编译内核
（1）准备源码
从github下载最新源码：https://github.com/chitao1234/linux-99pi-plus
sudo apt update
sudo apt install zip unzip
unzip linux-99pi-plus-main.zip
cd linux-99pi-plus-main
（2）执行编译
如果是512M内存版本的久久派plus，执行
make ARCH=loongarch CROSS_COMPILE=loongarch64-unknown-linux-gnu- ls2k0300_99_pai_plus_512m_defconfig
make ARCH=loongarch CROSS_COMPILE=loongarch64-unknown-linux-gnu-
如果是1G内存版本的久久派plus，执行
make ARCH=loongarch CROSS_COMPILE=loongarch64-unknown-linux-gnu- ls2k0300_99_pai_plus_defconfig
make ARCH=loongarch CROSS_COMPILE=loongarch64-unknown-linux-gnu-
（3）转为uImage镜像
sudo apt install u-boot-tools
./build_99pi_uimage.sh
然后在目录下会生成一个uImage文件，可以拷贝出来
