RV1126 是 Rockchip 推出的一款编解码芯片CPU 为 4 核 ARM Cortex-A7 32 位专用于面向人工智能的机械视觉领域支持 4K 编解码支持 8 路 1080P 同时进行编解码内置 2.0TOPS的 NPU。像这种专用芯片芯片厂商都会给出芯片的 SDK 包进行二次开发用它来开发有很多好处比如不用安装一下特殊的软件和库自带交叉工具链、文件系统和第三方库可以直接编译出系统镜像开发环境搭建比较容易等等。但是开发自由度不够高更新软件版本很麻烦代码里有很多私货(芯片厂商自己定义的代码)等等 ⚫ app : 存放上层应用程序的目录。 ⚫ buildroot SDK 包使用的文件系统为 buildroot。 ⚫ build.sh 编译用的脚本使用方法后面会教。 ⚫ device/rockchip 存放每个平台的一些编译和打包固件的脚步和预备文件。 ⚫ docs 存放 RK 开发指导文件、平台支持列表、工具使用文档、Linux 开发指南等。 ⚫ envsetup.sh 要修改文件系统时候要设置的环境脚本。 ⚫ external : 存放相关的库包括音频视频等。 ⚫ kernel kernel 源码。 ⚫ makefile 整个 SDK 包编译的 Makefile。 ⚫ mkfirmware.sh 固件打包使用的脚本默认在当前路径下的 rockdev 目录。 ⚫ prebuilts : 存放交叉编译工具链。 ⚫ rkbin: 存放固件和工具。 ⚫ rkflash.sh : linux 下的系统烧录脚本。 ⚫ tools 存放固件和工具的目录。 ⚫ u-boot U-boot 源码目录。 ⚫ rockdev存放编译输出固件的目录(整个 SDK 包编译完成后就会创建
rv1126 模块代码目录相关说明
什么叫做模块代码一个完整的 SDK 包除了 kernel、u-boot、buildroot 之外还需要提供上层的第三方库和 APP第三方库和 APP 合起来叫做模块代码。
SDK 包下的脚本使用
build.sh 脚本使用
查看 build.sh 使用帮助
morganmorgan-machine:~/Work/rv1126$ ./build.sh lunch -h
Usage: build.sh [OPTIONS]
Available options:
BoardConfig*.mk -switch to specified board config
lunch -list current SDK boards and switch to specified board config

sys 41m30.641senvsetup.sh 脚本使用
envsetup.sh 脚本主要的作用是使能 buildroot 的配置文件。在 RV1126 这个芯片里一共可以选择的配置文件有 3 种分别为文件系统的配置文件recovery 分区的配置文件(此分区主要是用作升级和复原的文件系统它也是一个文件系统)和 libs 的配置文件(生成一些库方便 我们写应用层代码做测试导出文件系统的库文件)。
mkfirmware.sh 脚本使用
mkfirmware.sh 脚本主要的作用是把 uboot、kernel、文件系统等等进行打包和生成镜像。
rkflash.sh 脚本使用
rkflash.sh 脚本主要的作用是在 linux 系统下进行固件的烧录
U-Boot 编译和配置
RK 官方提供了很方便的编译方法直接运行以下./build.sh uboot 命令可以编译 uboot。
morganmorgan-machine:~/Work/rv1126$ ./build.sh uboot编译完成后会在 u-boot 目录下生成 uboot.img 文件和 rv1126_spl_loader_v1.08.108.bin 文件uboot.img 文件就是我们要烧录的 img 镜像rv1126_spl_loader_v1.08.108.bin 是启动引导uboot 的文件
uboot 的配置修改编译操作
选择要修改 Uboot 配置文件从板级文件知道 morganmorgan-machine:~/Work/rv1126/u-boot$ make alientek_rv1126_defconfig进入图形界面配置
morganmorgan-machine:~/Work/rv1126/u-boot$ make menuconfig把.config 保存为 defconfig
morganmorgan-machine:~/Work/rv1126/u-boot$ make savedefconfig
scripts/kconfig/conf --savedefconfigdefconfig Kconfig更新修改好的配 置文件到alientek_rv1126_defconfig
morganmorgan-machine:~/Work/rv1126/u-boot$ cp defconfig configs/alientek_rv1126_defconfig重新编译 uboot
morganmorgan-machine:~/Work/rv1126$ ./build.sh uboot红色框里打印日期为“2024-01-12 22:34:42
kernel 的修改编译
选择要修改的 kernel 配置文件
morganmorgan-machine:~/Work/rv1126/kernel$ make ARCHarm alientek_rv1126_defconfig
#
# configuration written to .config
#进入图形界面配置
morganmorgan-machine:~/Work/rv1126/kernel$ make ARCHarm alientek_rv1126_defconfig把.config 保存为 defconfig
morganmorgan-machine:~/Work/rv1126/kernel$ make ARCHarm savedefconfig
scripts/kconfig/conf --savedefconfigdefconfig Kconfig更 新 修 改 好 的 配 置 文 件 到 alientek_rv1126_defconfig cp defconfig arch/arm/configs/alientek_rv1126_defconfig 编译内核 morganmorgan-machine:~/Work/rv1126$ ./build.sh kernel配置完成后我们可以直接用 build.sh kernel 脚本进行编译了就会生成我们想要的 zboot.img 文件 烧录成功会自动重启我们查看打印信息内核有没有替换成功
rootfs 编译和配置
buildroot 配置
在 SDK 包源码目录下运行以下命令进行配置 buildroot 配置 buildroot 对应 defconfig
