EB-RV1126-BC-191_SDKV2.2.0-入门开发_专栏

一，前期准备

准备材料：ubuntu1804虚拟机
SDK：RV1126_RV1109_LINUX_SDK_V2.2.5_20221009.tar.gz
(为什么不用1.8.0，因为有坑，因为这个版本更好用一点)
板子：EB-RV1126-BC-191+ IMX415

二，编译

安装依赖包：

apt-get install repo git ssh make gcc libssl-dev liblz4-tool  expect g++ patchelf chrpath gawk texinfo chrpath diffstat binfmt-support  qemu-user-static live-build bison flex fakeroot cmake gcc-multilib g++-multilib unzip  device-tree-compiler python-pip libncurses5-dev

编译

在复制SDK的时候想要吐槽一下，是哪位大佬打的包SDK文件近40G，没有把中间文件删除掉再去压缩，作案手法不是太专业。
如果想瘦身一下的话可以先看步骤四。

解压SDK
tar -xvf RV1126_RV1109_LINUX_SDK_V2.2.5_20221009.tar.gz
到RV1126目录下
cd RV1126_RV1109_LINUX_SDK_V2.1.0_20210512
. envsetup.sh

95. rockchip_rv1126_rv1109_pcba
96. rockchip_rv1126_rv1109_ramboot_uvcc
97. rockchip_rv1126_rv1109_recovery
98. rockchip_rv1126_rv1109_sl
99. rockchip_rv1126_rv1109_spi_nand
100. rockchip_rv1126_rv1109_spi_nand_recovery
101. rockchip_rv1126_rv1109_systemd

选[99] rockchip_rv1126_rv1109_spi_nand

./build.sh lunch

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

0. default BoardConfig.mk
1. BoardConfig-38x38-emmc.mk
2. BoardConfig-38x38-spi-nand-ab.mk
3. BoardConfig-38x38-spi-nand.mk
4. BoardConfig-ab-v13.mk
5. BoardConfig-aybering(bk).mk
6. BoardConfig-aybering.mk

选[3]BoardConfig-38x38-spi-nand.mk

完整编译./build.sh

目前文件
rockdev/update.img
分步编译
编译UBOOT执行:./build.sh uboot

编译kernel执行:./build.sh kernel

编译buildroot执行:./build.sh buildroot

编译软件包执行：make xxx
例如:make ffmpeg 或者 make libsrtp

编译external和app目录下的软件
make mediaserver
make ispserver

三，烧写

打开tools工具
瑞芯微开发工具v2.84

如上所示，点切换，即可进入Loader模式。
选择-->固件(刚刚编译生成的:rockdev/update.img)

如果因为烧了错误的固件导致变砖-不要慌，使用如下方便进入MASKROM模式
找到ebaina给的文档<02.EB-RV1126-BC-191型整板快速入门手册V2.1.pdf> 6.4节

如上方法可进入MASKROM模式，然后选择正确的固件烧写。

四，遇到的一些问题

使用ebaina给的SDK，如上编译出来的固件发现登录web网页，看不到视频。
于是检查buildroot的配置
修改如下位置
A,修改mediaserver的启动参数（在可以设备端去修改）
位置:device/rockchip/oem/oem_ipc/RkLunch.sh

# TODO:
# HasAudio=0

#if [ $HasDisplay -eq 1 ]; then
#       if [ $HasHDMI -eq 1 ]; then
#               mediaserver -c /oem/usr/share/mediaserver/rv1109/ipc-hdmi-display.conf &
#       else
#               if [ -z "$QUICKDISPLAY" ]; then
#                       if [ $HasAudio -eq 1 ]; then
#                               mediaserver -c /oem/usr/share/mediaserver/rv1109/ipc-display.conf &
#                       else
#                               mediaserver -c /oem/usr/share/mediaserver/rv1109/ipc-display-without-audio.conf &
#                       fi
#               else
#                       if [ $HasAudio -eq 1 ]; then
#                               mediaserver -c /oem/usr/share/mediaserver/rv1109/ipc.conf &
#                       else
#                               mediaserver -c /oem/usr/share/mediaserver/rv1109/ipc-without-audio.conf &
#                       fi
#               fi
#       fi
#else
#       if [ $HasAudio -eq 1 ]; then
                mediaserver -c /oem/usr/share/mediaserver/rv1109/ipc.conf &
#       else
#               mediaserver -c /oem/usr/share/mediaserver/rv1109/ipc-without-audio.conf &
#       fi
#fi

B,修改buildroot配置
位置:buildroot/configs/rockchip_rv1126_rv1109_spi_nand_defconfig

#include "base.config"
#include "base_extra.config"  #add by zcx
#include "debug.config"

C，编译
将buildroot/output/rockchip_rv1126_rv1109_spi_nand 删掉重启编译。

D，注意
RV1126的sensor配置在builroot defconfig文件和内核设备树均有配置支持的sensor型号
核对好自己的sensor板型号对号修改。
默认ebaina发的是imx415。如图rockchip_rv1126_rv1109_spi_nand_defconfig有支持。

四，SDK瘦身
发现SDK中无用的文件是有点太多(编译后的废料文件，repo备份)
rm .repo 删除掉repo备份，这个一般用不上，自己重新建一个git就可以了。
rm rockdev/ 编译后的镜像文件
rm IMAGE/ 每次编译生成的镜像文件
rm buildroot/output/* 编译时生成的中间文件。
删除完以上文件之后，就可以重新创建git仓库，硬盘空间会空出很多很多。
如果想重新打包SDK的话，
只需要压缩.git文件夹的就可以了
tar zcvf RV1126_RV1109_LINUX_SDK.tar.gz RV1126_RV1109_LINUX_SDK_V2.1.0_20210512/.git

使用时
解压SDK
git rest --hard 即可。
