Hi3518EV300芯片linux系统配置USB Camera功能
Hi3518EV300芯片linux系统配置USB Camera功能一，安装好虚拟机VMware® Workstation 15 Pro 和Ubuntu16.04 64位版本；并且安装应用软件，配置好 NFS、 telnetd、 samba、 VIM等等工具；
二，SDK版本Hi3516EV200R001C01SPC012\01.software\board\Hi3516EV200_SDK_V1.0.1.2.tgz该文件就是 Hi3518E V300 的软件开发包，
1， 在 linux 服务器上（或者一台装有 linux 的 PC 上，主流的 linux 发行版本均可以），使用命令：tar -zxf Hi3516EV200_SDK_Vx.x.x.x.tgz，解压缩该文件，可以得到一个Hi3516EV200_SDK_Vx.x.x.x 目录。
2，返回 Hi3516EV200_SDK_Vx.x.x.x 目录，运行./sdk.unpack(请用 root 或 sudo 权限执行)将会展开 SDK 包打包压缩存放的内容，请按照提示完成操作。如果您需要通过 WINDOWS 操作系统中转拷贝 SDK 包，请先运行./sdk.cleanup，收起SDK 包的内容，拷贝到新的目录后再展开。
三，软件包的安装：
详见：“Hi3516EV200╱Hi3516EV300╱HI3518EV300╱Hi3516D V200 U-boot 移植应用开发指南.pdf”1.3.3章节；
四，安装交叉编译工具 arm-himix100-linux.tgz
1，安装 himix100 交叉编译器：
解压 tar –xzf arm-himix100-linux.tgz，运行 chmod +x arm-himix100-linux.install，然后运
行./arm-himix100-linux.install 即可。
2， 执行 source /etc/profile，安装交叉编译器的脚本配置的环境变量就可以生效了，或者请重新登陆也可。
重新生效的时候，颜色变成白色；
3，每个SDK有配套的编译工具链，编译器分uclibc和glibc版本，比如arm-hisiv300-linux为uclibc版本，对应的glibc版本为arm-hisiv400-linux；
4，如果要想看编译器支持哪些特性，可以通过arm-hisixxx-gcc –v 查看对应的GCC版本号，然后在GNU网站查看该版本的GCC支持的特性
arm-himix100-linux-gcc -v
5，如果不同芯片的SDK使用的工具链名称相同，那么该工具链可以通用，编译服务器上只需要安装一个最新版本即可。 比如Hi3536C 和Hi3536D 都使用arm-hisiv500-linux工具链，那么Hi3536C SDK带的hisiv500工具链也适用于Hi3536D；
五，编译OSDRV; 参见 osdrv 目录下 readme;
make OSDRV_CROSS=arm-himix100-linux CHIP=hi3518ev300 all
编译完成后，在osdrv/pub/中有已经编译好的文件系统，因此无需再重复编译文件系统，只需要根据单板上flash的规格型号制作文件系统镜像即可。
六，串口设置：Hi3518EV300 有个3pin的白色插座，依次是：TxD RXD GND 信号！推荐用 mobaXterm工具，波特率设置：115200；
注意下串口的电平为：LVCMOS3.3V，要用USB转串口的小板子，若是连接PC电脑的串口需要增加MAX232转换芯片才可以；
推荐用： 英国进口FR232RL芯片的串口小板子，一般价格在20元左右，质量很好，避免串口弄坏，损坏到主控Hi3518EV300板子！
七，固件烧录，Hi3518EV300芯片支持USB或者SD卡烧录；
1，介绍使用Hitool工具USB口单板烧录方法
Hitool工具安装：建议使用HiTool-BVT-5.0.60以上版本，详见SDK说明：
HiTool工具平台 使用指南.pdf
HiBurn 工具使用指南.pdf
确保Hitool工具正常运行，
HiMobileCam SDK安装使用说明(Huawei LiteOS).pdf 文章：5.2.1.2 USB 口烧写章节：
2，烧写准备 请下载Windows PC 上安装USB 驱动安装程序zadig.exe，此软件可从http://zadig.akeo.ie上下载。确保单板已连接串口和USB 线(请选用较短且质量好的USB 连接线)。
步骤 1 连接电源，单板上电；
步骤 2 请参照5.2.1.1 烧写并运行u-boot，按键进入uboot命令行；
步骤 3 uboot命令行中使用“usb device”命令，使单板进入usb 驱动待安装状态，见下图：
步骤 4 PC上打开zadig工具，勾选Options->List All Devices；
步骤 5 在下拉列表中选择新识别的usb设备“HiUSBBurn”；
步骤 6 请参考《HiBurn 工具使用指南》1.5节环境准备步骤7，依次安装好驱动LibusbK和
libusb-win32；
步骤 7 右键点击PC“计算机”，依次点击“管理”，“设备管理器”，观察设备驱动
libusbK USB Device –>HiUSBBurn是否安装成功；安装成功后如图5-3 所示。
3，镜像烧写：
八，设置环境参数
setenv bootargs ‘mem=32M console=ttyAMA0,115200 root=/dev/mtdblock2 rootfstype=jffs2 rw mtdparts=hi_sfc:1M(boot),4M(kernel),11M(rootfs)’
setenv bootcmd ‘sf probe 0;sf read 0x42000000 0x100000 0x400000;bootm 0x42000000’
sa
九，运行UVC业务，支持linux版本的；
1， 修改\Hi3516EV200_SDK_V1.0.1.2\mpp\sample\Makefile.param
海思SDK交付默认是imx307,但是单板sensor是sc2231,需要修改为：SENSOR0_TYPE ?= SMART_SC2231_MIPI_2M_30FPS_10BIT
2， 进入Hi3516EV200_SDK_V1.0.1.2\mpp\sample\uvc_app\Makefile.linux.param
修改为：UAC_COMPILE := y
详见该目录下readme.txt
最后，编译得到“uvc_app” “uvc_app.conf”
3， alsa安装和编译，详见alsa_readme.txt
最终将Ubuntu16.04 路径下/home/install/alsa-lib-1.1.7/lib/libasound.so.2 拷贝到Hi3518EV300单板/lib/
/home/audio/alsa/ 拷贝到Hi3518EV300单板/home/audio/alsa/
4， 内核下USB Device操作过程，修改内核kernel，生成uImage和USB摄像头相关的XXXX.Ko文件；
进入：Hi3516EV200_SDK_V1.0.1.2\osdrv\opensource\kernel\linux-4.9.y目录下，详见“外围设备驱动 操作指南.doc”文档；
A,输入：cp arch/arm/configs/hi3518ev300_full_defconfig .config #选择Hi3518EV300芯片配置；
B,然后：make ARCH=arm CROSS_COMPILE=arm-himix100-linux- menuconfig 进入menuconfig的如下路径，USB2.0 device 作为网口、串口、u盘、摄像头的配置如下
PHY选项
音频驱动配置选项
<> Sound card support —>
<> Advanced Linux Sound Architecture —>
[] USB sound devices (NEW) —>
<> USB Audio/MIDI driver
USB Gadget 功能选项
内核模块主要选项图
C，配置好，退出，记得保存；
D，输入：make ARCH=arm CROSS_COMPILE=arm-himix100-linux- uImage 在目录下arch/arm/boot/uImage生成kernel镜像 uImage；
E，输入：make ARCH=arm CROSS_COMPILE=arm-himix100-linux- modules 生成摄像头相关的驱动；
在目录linux-4.9.y\drivers\usb\gadget和 linux-4.9.y\drivers\usb\gadget\function 找到如下5个KO文件；
libcomposite.ko
usb_f_uvc.ko
u_audio.ko
usb_f_uac1.ko
usb_f_uac2.ko
5， 制作rootfs_uclibc_64k.jffs2烧录镜像；
A，回到第五步骤，编译OSDRV目录后，在\Hi3516EV200_SDK_V1.0.1.2\osdrv\pub目录下生成rootfs_uclibc.tgz压缩包，然后解压；
B，详见文档“外围设备驱动 操作指南.doc”2.3.8.2章节：进入rootfs_uclibc目录，创建root文件夹，拷贝USB2.0 device摄像头要的UVC_app、Ko、lib、脚本等，
mkdir root
chmod –R 777 root
C，修改KO目录下loadhi3518ev300脚本“SNS_TYPE0=sc2231;”
D，增加/etc/init.d/rcS
cd /root/
insmod libcomposite.ko
insmod usb_f_uvc.ko
insmod u_audio.ko
insmod usb_f_uac1.ko
insmod usb_f_uac2.ko
export VID=“0x12d1”
export PID=“0x4321”
export MANUFACTURER=“Huawei”
export PRODUCT=“HiCamera”
export SERIALNUMBER=“12345678”
export YUV=“360p”
export MJPEG=“360p 720p 1080p”
export H264=“360p 720p 1080p”
./ConfigUVC.sh
cd /root/ko
./load3518ev300 -a -sensor sc2231 -osmem 32M
cd /root/
./ uvc_app &
E, 拷贝01.software/pc/usb_tools/ConfigUVC.sh 文件；
F，现在需要把这个 Hi3516EV200_SDK_V1.0.1.2\osdrv\pub\rootfs_uclibc 目录下文件，做成rootfs_hi3518ev300_64k.jffs2 这个怎么弄？ 才好烧录到Hi3518EV300的板子上；
进入Hi3516EV200_SDK_V1.0.1.2\osdrv\pub\bin\pc目录下，运行mkfs.jffs2工具，制作jffs2镜像，
./mkfs.jffs2 -d /home/samba/Hi3516EV200_SDK_V1.0.1.2/osdrv/pub/rootfs_uclibc -l -e 0x10000 –o
/home/samba/Hi3516EV200_SDK_V1.0.1.2/osdrv/pub/rootfs_uclibc_64k.jffs2 #这个2行是连在一起，注意中间空格#
十，烧录编译和制作好的 kernel和rootfs;
烧录完成后，设置启动参数；使用PotPlayer软件进行音视频捕获
附录一： 单板启动uart0启动消息；
System startup
