Busybox系统编译

电脑硬件配置​

编译 Ubuntu 开发环境电脑硬件配置建议：

  • 64 位 CPU
  • Ubuntu22.04系统，不要使用 Windows 子系统 (WSL)
  • 16GB 内存
  • 80GB 空闲空间用来编译
  • 普通用户编译，不要使用 root 用户编译

SDK下载​

mkdir sdk-dir && cd sdk-dir  
  
git clone http://git.neardi.com/repo-release/tools/repo.git  
  
./repo/repo init --no-clone-bundle --repo-url=http://git.neardi.com/repo-release/tools/repo.git -u http://git.neardi.com/hisilicon/manifests.git -b hi3516-cv610 -m neardi_3516-cv610_linux5.10_next.xml  
  
.repo/repo/repo sync

编译环境配置​

可参考neardi_3516-cv610_linux5.10_next/readme_en.txt进行环境搭建。

安装环境包

## 1. Ubuntu 22.04 uses dash by default, which breaks SDK compile. Switch to bash:
    ~ $ sudo dpkg-reconfigure dash  
  
    Note: Select No when asked  
  
## 2. Install System Dependencies
    ~ $ sudo apt update && sudo apt install -y make libc6-i386 lib32z1 lib32stdc++6 libncurses5-dev \  
        ncurses-term libncursesw5-dev g++ u-boot-tools texinfo gawk libssl-dev openssl \  
        bc p7zip-full gperf bison flex diffutils git unzip libffi-dev libtool libfreetype6 \  
        fakeroot autopoint po4a python3-pip wget libmpc-dev  
  
    ~ $ sudo apt install -y zlib1g-dev liblzo2-dev uuid-dev pkg-config automake texlive  
  
    ~ $ sudo pip3 install --upgrade pip wheel  
    ~ $ sudo pip3 install pyelftools cryptography pycryptodome -i https://mirrors.aliyun.com/pypi/simple/  
  
## 3. Configure Cross-Compiler
    ~ $ cd toolchain  
    ~ $ sudo ./install_gcc_toolchain.sh  
    ~ $ source /etc/profile  
    ~ $ cd ../ && sudo chown -R $USER:$USER ./  
    （可选，若sudo make install无法安装，添加/opt/linux/x86-arm/arm-v01c02-linux-musleabi-gcc/bin至secure_path路径）  
    ~ $ sudo visudo       
        Defaults  secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin:/opt/linux/x86-arm/arm-v01c02-linux-musleabi-gcc/bin"  
  
## 4. Fix Missing Links
    ~ $ cd /opt/linux/x86-arm/arm-v01c02-linux-musleabi-gcc/bin  
    ~ $ sudo ln -s ../tools/ tools  
    ~ $ sudo ln -s ../target/ target  
    ~ $ cd target  
    ~ $ sudo ln -s usr/lib/ lib  
  
## 5. Compile util-linux-2.38.1
    ~ $ cd neardi_3516-cv610_linux5.10_next/open_source/util-linux-2.38.1  
    ~ $  ./configure   --prefix=/opt/linux/x86-arm/arm-v01c02-linux-musleabi-gcc/arm-linux-musleabi \  
                       --host=arm-v01c02-linux-musleabi \  
                       --disable-all-programs \  
                       --enable-libblkid \  
                       --without-ncurses  
    ~ $ make && sudo make install  
  
## 6. Install gperf-3.1
    ~ $ cd neardi_3516-cv610_linux5.10_next/open_source/eudev/gperf-3.1  
    ~ $ ./configure  
    ~ $ make && sudo make install

编译 SDK​

整体编译：

cd smp/a7_linux/source/bsp  
make LIB_TYPE=musl CHIP=hi3516cv610 DEBUG=1  all  
  
# 编译uboot
make LIB_TYPE=musl CHIP=hi3516cv610 DEBUG=1 gslboot_build  
  
# 编译uboot_env
make LIB_TYPE=musl CHIP=hi3516cv610 DEBUG=1 uboot_env  
  
# 编译kernel
make LIB_TYPE=musl CHIP=hi3516cv610 DEBUG=1 kernel  
  
# 编译rootfs
make LIB_TYPE=musl CHIP=hi3516cv610 DEBUG=1 rootfs_build

单独编译kernel：

kernel defconfig: hi3516cv610_debug_defconfig  
kernel dts:       hi3516cv610-demb.dts  
  
# 编辑配置
make ARCH=arm CROSS_COMPILE=arm-v01c02-linux-musleabi- hi3516cv610_debug_defconfig menuconfig  
# 保存配置
make ARCH=arm CROSS_COMPILE=arm-v01c02-linux-musleabi- hi3516cv610_debug_defconfig savedefconfig  
cp defconfig arch/arm/configs/hi3516cv610_debug_defconfig  
# 编译kernel
make ARCH=arm CROSS_COMPILE=arm-v01c02-linux-musleabi- hi3516cv610_debug_defconfig uImage  
  
# 编译kernel ko
