Buidlroot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
  • Ubuntu18.04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

sudo pip2 install pycryptodome

SDK获取​

创建 SDK 工作目录​

mkdir neardi-hi3516-dv500-linux-5.10  
  
cd neardi-hi3516-dv500-linux-5.10  
  
git reset --hard

编译 SDK​

环境依赖 docker 18.04​

sudo apt-get install -y make libc6-i386 lib32z1 lib32stdc++6 libncurses5-devncurses-term libncursesw5-dev g++ u-boot-tools texinfo gawk libssl-dev opensslbc p7zip-full gperf bison flex diffutils git unzip libffi-dev libtool libfreetype6fakeroot autopoint po4a zlib1g-dev liblzo2-dev uuid-dev pkg-config automake texlive
sudo apt install -y libc6-i386 libncursesw5-dev lib32z1 lib32stdc++6 ncurses-term libncursesw5-dev libffi-dev libtool autopoint po4a p7zip-full texlive liblzo2-dev python3-pip && pip3 install pyelftools pycryptodome
cd /mnt/data/sundongya/3519/linux/gcc-20231123-aarch64-v01c01-linux-musl  
  
sudo ./install_gcc_toolchain.sh && source /etc/profile

编译​

LKD3516DV500 和 LKD3519DV500 共用同一份 SDK，因此在编译时需配置对应型号

1. buildroot 选择

cd Hi3519DV500_SDK_V1.0.1.1/open_source/buildroot/buildroot-2022.02.11  
sudo make menuconfig  
    System configuration  --->  
         (neardi/rootfs/hi3519dv500/overlay/) Root filesystem overlay directories  # 此处改为neardi/rootfs/hi3519dv500/overlay/

保存退出

2. 切换分支

执行以下命令查看分支：

git branch -a

执行以下命令切换分支：

git checkout 3519

3. 修改 DDR 大小

cd SDK/smp/a55_linux/source/bsp  
  
vi Makefile  
  
ifeq ($(CHIP),hi3519dv500)  
#REGBIN_XLSM ?=Hi3519DV500-DMEBPLUS_6L_T_LPDDR4X_2933M-2GB_32bit-A55_1G.xlsm      
REGBIN_XLSM ?=Hi3519DV500-DMEBPLUS_6L_T_LPDDR4X_2933M-1GB_32bit-A55_1G.xlsm  
else ifeq ($(CHIP),hi3516dv500)  
REGBIN_XLSM ?=Hi3516DV500-DMEBPLUS_6L_T_LPDDR4X_2400M-1GB_32bit-A55_850M.xlsm  
else  
$(error you must set valid CHIP: hi3519dv500 | hi3516dv500)  
endif

DDR文件位于：SDK/smp/a55_linux/source/bsp/tools/pc/boot_tools/*

4. 编译

cd smp/a55_linux/source/bsp/  
  
# 整体编译：
make all  
  
# 单独编译 uboot:
make gslboot_build  
  
# 单独编译 kernel:
make kernel  
  
# 单独编译 rootfs:
    # a.编译 busybox  
    make rootfs  
  
    # b.编译 buildroot:  
    cd open_source/buildroot/buildroot-2022.02.11/  
    sudo make -j 99  
  
# 编译 sample
cd ./smp/a55_linux/source/mpp/sample  
make -j 99
