编译手册
编译环境要求：
编译主机需在 ubuntu 系统中进行，笔者主机系统为 ubuntu 22.04，推荐使用与笔者相同版本的 ubuntu，避免因为版本不同导致一些工具出现兼容问题。
安装库和工具集：
sudo apt-get update && sudo apt-get install git ssh make gcc libssl-dev \
liblz4-tool expect expect-dev g++ patchelf chrpath gawk texinfo chrpath \
diffstat binfmt-support qemu-user-static live-build bison flex fakeroot \
cmake gcc-multilib g++-multilib unzip device-tree-compiler ncurses-dev \
libgucharmap-2-90-dev bzip2 expat gpgv2 cpp-aarch64-linux-gnu libgmp-dev \
libmpc-dev bc python-is-python3 python2 gettext libc6-dev libncurses-dev rsync
(python 版本要求在 python3.6 及以上版本)
(make 版本要求在 make4.0 及以上版本)
(lz4 版本要求在 lz4 1.7.3 及以上版本)
下载源码包
下载 RV1126b 源码包。
创建编译目录：
mkdir -p ~/my-work/RV1126b/
把源码放到刚创建的目录中，将分卷解压的源码进行合并，随后在解压：
cat myzr-rv1126b.tar.gz.part-* > myzr-rv1126b.tar.gz
tar xvf myzr-rv1126b.tgz -C ~/my-work/RV1126b/

进行全局编译并进行固件打包：
./build.sh
只进行全局编译，不执行固件打包操作
./build.sh all
只进行固件打包
./build.sh firmware
清理 SDK 目录：
./build.sh cleanall
各模块单独编译
单独编译 U-Boot：
./build.sh uboot
单独编译 Kernel：
./build.sh kernel
单独编译 recovery：
./build.sh recovery
单独编译 buildroot：
./build.sh rootfs
各个模块单独编译完成后，会自动打包固件，无需再次执行固件打包操作。
