20230112编译AIO-3568J的Buildroot（rk356x_linux_release_v1.3.0b_20221213）
2023/1/12 20:40
当前可以拿到的Buildroot的SDK；
rk356x_linux_release_v1.0.0_20210511_split_dir
rk356x_linux_release_v1.2.0_20211019_split_dir
rk356x_linux_release_v1.3.0b_20221213_split_dir（最新的SDK）
如果编译rk356x_linux_release_v1.3.0b_20221213_split_dir，建议使用Ubuntu18.04（Firefly官方使用）和Ubuntu20.04。
如果需要使用OpenHarmony（python3.8以上），那就使用Ubuntu20.04（Ubuntu18.04默认Python3.6）
如果使用Ubuntu22.04，你就会增长很多知识！

Core-3568J-4. 编译 Buildroot 固件
Core-3568J产品规格书
Core-3568J 采用 RK3568 四核 64 位 Cortex-A55 处理器,22 nm 先进工艺，主频最高2.0GHz, 集成双核心架构GPU以及高效能NPU；最大支持8G大内存；支持WiFi6，5G/4G等高速无线网络通讯；拥有丰富的接口扩展，支持多种视频输入输出接口，可适用于智能NVR、云终端、物联网网关、工业控制等场景
4. 编译 Buildroot 固件
本章介绍 Buildroot 固件的编译流程，推荐在 Ubuntu 18.04 系统环境下进行开发，若使用其它系统版本，可能需要对编译环境做相应调整。
4.1. 编译 SDK
4.1.1. 编译前配置
不同板型的配置文件存放在device/rockchip/rk356x/目录下
回到 SDK 根目录执行build.sh选择配置文件：
./build.sh aio-3568j-buildroot.mk
配置文件会链接到 device/rockchip/.BoardConfig.mk，检查该文件可以验证是否配置成功。

在 device/rockchip/rk356x/ 目录下，除了aio-3568j-buildroot.mk之外，还有其他不同配件搭配的配置文件
配置文件的名称中会标明所使用的屏幕和摄像头。如果没有标明屏幕，说明使用的是默认 HDMI 显示；如果没有标明摄像头，说明使用的是默认单目摄像头
# 例如：
xxxx-buildroot.mk # 使用 HDMI + 单目摄像头
xxxx-2cam-buildroot.mk # 使用 HDMI + 双目摄像头
xxxx-mipi-buildroot.mk # 使用 mipi + 单目摄像头
xxxx-mipi-2cam-buildroot.mk # 使用 mipi + 双目摄像头
选择好配置文件后，执行build.sh来使其生效：
# 例如：
./build.sh xxxx-mipi-2cam-buildroot.mk
4.1.3. 全自动编译
全自动编译会执行所有编译、打包操作，生成完整固件。
./build.sh
4.1.4. 部分编译
编译 u-boot
./build.sh uboot
编译 kernel
注意：Firefly kernel 没有开启全部的内核功能，有需求请查看Kernel 使用
./build.sh kernel
编译 recovery
./build.sh recovery
编译 Buildroot 根文件系统
编译 Buildroot 根文件系统，将会在 buildroot/output 生成编译输出目录：
./build.sh buildroot
# 注：确保作为普通用户编译 Buildroot 根文件系统，避免不必要的错误。
4.1.5. 打包固件
更新各部分镜像链接到 rockdev/ 目录：
./mkfirmware.sh
打包固件，生成的完整固件会保存到 rockdev/pack/ 目录。
./build.sh updateimg
4.2. 分区说明
4.2.1. parameter 分区表
parameter.txt 文件中包含了固件的分区信息，以 parameter-buildroot-fit.txt 为例：
路径：device/rockchip/rk356x/parameter-buildroot-fit.txt

CMDLINE 属性是我们关注的地方，以 uboot 为例， 0x00002000@0x00004000(uboot) 中 0x00004000 为uboot 分区的起始位置，0x00002000 为分区的大小，以此类推。
4.2.2. package-file
package-file 文件用于打包固件时确定需要的分区镜像和镜像路径，同时它需要与 parameter.txt 文件保持一致。
