前言

环境介绍：

1.编译环境

Ubuntu 18.04.5 LTS

2.SDK

Hi3519AV100_SDK_V2.0.1.0

3.单板

Hi3519AV100开发板

一、MPP介绍

MPP 即Media Process Platform媒体处理平台，是集成视频输入(VI)、视频处理(VPSS)、视频编码(VENC)、视频解码(VDEC)、视频输出(VO)、视频侦测分析(VDA)、音频输入(AI)、音频输出(AO)、音频编码(AENC)、音频解码(ADEC)、区域管理(REGION）等模块，可以说是海思芯片的核心业务。相关内容可以参考海思《HiMPP V4.0 媒体处理软件开发参考》、《HiMPP 媒体处理软件 FAQ》。
下面以Hi3519AV100为例介绍怎么把这模块功能部署到单板上。

二、解压、编译

我这里已经把海思SDK放到服务器解压安装好了，交叉编译工具也安装好了。海思芯片SDK、交叉编译工具安装都差不多的。
MPP位于：Hi3519AV100_SDK_V2.0.1.0/smp/a53_linux/mpp/
在部署到单板之前先把mpp编译一下

2.1 先编译sensor相关ko文件

在这路径编译/Hi3519AV100_SDK_V2.0.1.0/smp/a53_linux/mpp/component/isp/user/

make会出现找不到kernel路径的情况

原因是编译默认的路径是linux-4.9.y-smp，而实际是linux-4.9.y，这里可以通过添加软连接解决
ln -s linux-4.9.y linux-4.9.y-smp

在kernel路径输入命令如下

zfeng@ubuntu:~/hisi/hi3519a/Hi3519AV100_SDK_V2.0.1.0/osdrv/opensource/kernel$ ln -s linux-4.9.y linux-4.9.y-smp

zfeng@ubuntu:~/hisi/hi3519a/Hi3519AV100_SDK_V2.0.1.0/osdrv/opensource/kernel$

接着在make编译会出现找不到gcc

zfeng@ubuntu:~/hisi/hi3519a/Hi3519AV100_SDK_V2.0.1.0/smp/a53_linux/mpp/component/isp/user/sensor/hi3519av100$ make

这里出现gcc找不到情况，但通过arm-himix200-linux-gcc -v却能正常找到找到gcc

zfeng@ubuntu:~/hisi/hi3519a/Hi3519AV100_SDK_V2.0.1.0/smp/a53_linux/mpp/component/isp/user/sensor/hi3519av100$ arm-himix200-linux-gcc -v

这是可以通过sudo -s命令解决

至此sensor的相关ko文件可以编译完成。

2.2 编译sample

sample路径Hi3519AV100_SDK_V2.0.1.0/smp/a53_linux/mpp/sample
要是上面的问题处理完之后，这里可以直接编译通过。

二、单板mount

单板的文件系统使用的SDK默认的。
路径hi3519a/Hi3519AV100_SDK_V2.0.1.0/smp_image_glibc/rootfs_hi3519av100_32M.ext4
系统起来后默认网络不配的，可以通过下面方法自动添加网络。
在 /etc/init.d/rcS后续添加/etc/init.d/demo

~ # cat /etc/init.d/rcS
#! /bin/sh/bin/mount -aecho "_ _ _ _ _ _ _ _ _ _ _ _\  _  _   _  _ _ ___/ /__/ \ |_// __   /  -  _ ___/ /  / /  / /_ _ _ _/ /  /  \_/  \_ ______
___________\___\__________________
"
for initscript in /etc/init.d/S[0-9][0-9]*
doif [ -x $initscript ] ;thenecho "[RCS]: $initscript"$initscriptfi
done/etc/init.d/demo

再在/etc/init.d路径下添加文件demo，内容为

~ # cat /etc/init.d/demo
#!/bin/sh
ifconfig eth0 192.168.1.119 netmask 255.255.255.0;route add default gw 192.168.1.1
~ #

单板网络配置好之后通过下面mount到服务器的mpp目录
mount -t nfs -o nolock 192.168.1.230:/home/zfeng/hisi/hi3519a/Hi3519AV100_SDK_V2.0.1.0/smp/a53_linux /mnt

~ # mount -t nfs -o nolock 192.168.1.230:/home/zfeng/hisi/hi3519a/Hi3519AV100_SD
K_V2.0.1.0/smp/a53_linux /mnt
~ # ls /mnt/
drv                         mpp
hi3519a_smp.code-workspace  osal
~ #

服务器能需要开启nfs服务，相关操作可参考我之前的文章
Hi3519v101通过NFS挂载到服务器启动
单板挂载之后，来到ko目录

/mnt/mpp # cd /mnt/mpp/ko/
/mnt/mpp/ko # ls

至此mpp部署完成。
mpp sample大部分都跟sensor相关，使用之前必须把sensor驱动与实际使用的sensor配置好。
