ax-pipeline交叉编译

编译前准备

• x86 Linux系统，虚拟机或者实体机，推荐选择Ubuntu 22.04
• 稳定网络环境(需要连接github)，若下载出现问题可参考此处
• U盘
• 安装基础编译包

sudo apt update
sudo apt install build-essential libopencv-dev cmake

交叉编译

• 拉取ax-pipeline源码及子模块

git clone --recursive https://github.com/AXERA-TECH/ax-pipeline.git

• 下载sdk及设置650n_bsp_sdk版本

cd ax-pipeline
./download_ax_bsp.sh ax650
./switch_version_ax650.sh 1.45
cd ax650n_bsp_sdk
wget https://github.com/ZHEQIUSHUI/assets/releases/download/ax650/drm.zip
mkdir third-party
unzip drm.zip -d third-party
cd ..

• 下载opencv

mkdir 3rdparty
cd 3rdparty
wget https://github.com/ZHEQIUSHUI/assets/releases/download/ax650/libopencv-4.5.5-aarch64.zip
unzip libopencv-4.5.5-aarch64.zip

• 配置交叉编译器

wget https://developer.arm.com/-/media/Files/downloads/gnu-a/9.2-2019.12/binrel/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu.tar.xz
tar -xvf gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu.tar.xz
export PATH=$PATH:$PWD/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu/bin/

• 源码编译

cd ax-pipeline
mkdir build
cd build
cmake -DAXERA_TARGET_CHIP=AX650 -DBSP_MSP_DIR=$PWD/../ax650n_bsp_sdk/msp/out -DOpenCV_DIR=$PWD/../3rdparty/libopencv-4.5.5-aarch64/lib/cmake/opencv4 -DSIPY_BUILD=OFF -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=../toolchains/aarch64-none-linux-gnu.toolchain.cmake -DCMAKE_INSTALL_PREFIX=install ..
make -j12
make install

• 获得bin文件如下所示

移动到开发板

由于编译后文件较大，因此推荐使用U盘进行数据传输

• 将编译后bin文件移动到U盘中

• U盘插入板卡中

• 查看U盘所在分区

如图所示，我的U盘所在分区为/dev/sda1 (根据大小或者其他来判断)

• 挂载到文件夹中(此处挂载到了/mnt/usb文件夹下)

mkdir /mnt/usb
mount /dev/sda1 /mnt/usb

可能会有以下提示，不影响

查看是否挂载

• 移动文件到板卡中(此处创建了~/data目录，并将文件移动到了~/data/下)

mkdir ~/data
cp /mnt/usb/bin ~/data -r

• 查看文件

• 运行默认示例，不传入模型参数(记得kill fb_vo进程)

cd ~/data/bin
./sample_vin_ivps_npu_hdmi_vo

• 移除U盘

卸载U盘

umount /dev/sda1 /mnt/usb

即可拔掉U盘

github镜像加速下载

1. git拉取ax-pipeline源码加速

git clone https://kkgithub.com/AXERA-TECH/ax-pipeline.git
cd ax-pipeline

修改ax-pipeline下.gitmodules文件， 将url =中所有github.com换为kkgithub.com

拉取子模块

git submodule update --init
./download_ax_bsp.sh ax650

2. wget文件加速

替换wget下载链接中github.com为kkgithub.com
