IPC SDK用户指南

开发环境硬件配置建议​

  • 64位CPU
  • Ubuntu 20.04系统
  • 8GB内存
  • 40GB编译空闲空间

软件配置​

SDK获取

发送邮件至[support@neardi.com](mailto:support@neardi.com)获取相关开发资料。

下载后，在解压前检查MD5码，看是否与LKD3588-SDK-Linux-IPC-V1.0.tar.gz.md5sum中的一致：

$ 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

初始化：

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

编译SDK​

选择配置​

./build.sh lunch  
  
You're building on Linux  
Lunch menu...pick a combo:  
  
  
0. BoardConfig-rk3588-neardi-linux-ipc-lkd3588-f1.mk

全自动编译​

全自动编译将执行所有构建。

./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

  • 编译内核
/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命令将其打包为rootfs.img 生成镜像文件：output/image/rootfs.img

  • 编译media
./build.sh clean media  
./build.sh media

生成文件的存储目录：output/out/media_out

  • 更多编译选项，请参考LKD3588-IPC-Software Development Documentation/LKD3588-IPC-Linux Original Development Documentation/Rockchip_Quick_Start_Linux_IPC_SDK_CN.pdf

刷写镜像​

SDK提供Windows刷写工具<SDK>/Tools/windows/SocToolKit/SocToolKit.exe

运行演示​

网络配置​

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

复制OV13855摄像头文件​

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服务器​

默认情况下，IPC APP已经在运行。在运行IPC之前，需要手动运行3A服务器。因此，首先杀死IPC APP：

 ps | grep rkipc  
  395 root     3482m S    rkipc -a /oem/usr/share/iqfiles  
  622 root      2396 S    grep rkipc  
  
kill -9 395

注意这里的395是IPC进程号，需要根据实际显示结果进行更改。

  • 启动3A服务
rkaiq_3A_server &

执行结果：

 Cound not find rkisp dev names, skipped /dev/media0  
ERR: Bad media topology for: /dev/media0

  • 重启IPC APP
rkipc -a /oem/usr/share/iqfiles/ &

执行结果：
