下载完成后，在解压前先查看 MD5 码和LKD3588-SDK-Linux-IPC-V1.0.tar.gz.md5sum中是否一致：

$ md5sum LKD3588-SDK-Linux-IPC-V1.0.tar.gz
******************************** LKD3588-SDK-Linux-IPC-V1.0.tar.gz

解压：

tar zxvf LKD3588-SDK-Linux-IPC-V1.0.tar.gz

提取：

cd LKD3588-SDK-Linux-IPC-V1.0
git reset --hard

切换分支：

lz16000003	Neardi master branch

git checkout lz16000003

编译 SDK

选择配置

./build.sh lunch

You're building on Linux
Lunch menu...pick a combo:

全自动编译

全自动编译会执行所有编译。

./build.sh

部分编译

编译 u-boot

./build.sh clean uboot
./build.sh uboot

生成镜像文件：output/image/download.bin、output/image/idblock.img 和 output/image/uboot.img

编译 kernel

/build.sh clean kernel
./build.sh kernel

生成镜像文件：output/image/boot.img

编译 rootfs

./build.sh clean rootfs
./build.sh rootfs

编译后使用 ./build.sh firmware 命令打包成rootfs.img 生成镜像文件：output/image/rootfs.img

编译 media

./build.sh clean media
./build.sh media

生成文件的存放目录：output/out/media_out

运行Demo

配置网络

ifconfig enP2p33s0 up

udhcpc -i enP2p33s0

执行结果

udhcpc: started, v1.27.2
udhcpc: sending discover
udhcpc: sending select for 192.168.1.237
udhcpc: lease of 192.168.1.237 obtained, lease time 86400
deleting routers
adding dns 192.168.1.1

拷贝OV13855 Camera 文件

adb push <SDK>/media/isp/release_camera_engine_rkaiq_rk3588_aarch64-rockchip1031-linux-gnu/isp_iqfiles/ov13855_CMK-OT2016-FV1_default.json /oem/usr/share/iqfiles

运行3A Server

默认情况下，IPC APP已经运行，在IPC运行之前需要手动运行3A server，因此先kill掉IPC APP

 ps | grep rkipc
  395 root     3482m S    rkipc -a /oem/usr/share/iqfiles
  622 root      2396 S    grep rkipc

kill -9 395

注意，此处395是IPC进程号，需要根据实际显示结果而改变。

启动3A服务

rkaiq_3A_server &
