一、`SDK`软件架构

1.1 `SDK`工程目录介绍

一个通用Linux SDK工程目录包含有buildroot、debian、app、kernel、u-boot、device、external等目录；

app：存放上层应用APP，主要是一些应用Demo；
buildroot：存放Buildroot开发的根文件系统；
debian：存放Debian开发的根文件系统；
device/rockchip：存放芯片板级配置以及一些编译和打包固件的脚本和文件；
docs：存放通用开发指导文档、Linux系统开发指南、芯片平台相关文档等；
external：存放第三方相关仓库，包括显示、音视频、摄像头、网络、安全、recovery 等；
kernel：存放Kernel开发的代码；
output：存放每次生成的固件信息、编译信息、XML、主机环境等；
prebuilts：存放外部交叉编译工具链；
rkbin：存放Rockchip相关二进制和工具；
rockdev：存放编译输出固件，实际软链接到output/firmware；
tools：存放Linux和Window操作系统下常用工具；
u-boot：存放基于v2017.09版本进行开发的U-Boot代码；
yocto：存放Yocto开发的根文件系统；

1.2 `SDK`概述

通用Linux SDK目前已集成主流的几个Linux发行版(Distribution)，发行版就是我们日常在Linux主机上使用的那些系统，为用户预先集成好的Linux操作系统及各种应用软件。Linux发行版的形式多种多样，有从功能齐全的桌面系统到服务器版本到小型系统。比如支持桌面版本的Debian系统，可定制化的Buildroot/Yocto轻量级系统。

1.2.1 `Buildroot`系统

Rockchip Linux SDK的Buildroot系统，其包含了基于Linux系统开发用到的各种系统源码，驱动，工具，应用软件包。Buildroot 是Linux平台上一个开源的嵌入式Linux系统自动构建框架。整个Buildroot是由Makefile脚本和Kconfig配置文件构成的。可通过Buildroot配置，编译出一个完整的可以直接烧写到机器上运行的Linux系统软件。

Buildroot有以下几点优势：

通过源码构建，有很大的灵活性；
方便的交叉编译环境，可以进行快速构建，容易上手；
提供系统各组件的配置，方便定制开发。

使用Buildroot的project最出名的就是Openwrt。可以看到，由它制作出的镜像可以跑在搭载16 Mb SPINOR的路由器上，系统基本没包含多余的东西。这就是得益于Buildroot的简单化。整个Buildroot工程在一个git维护。

Buildroot使用kconfig和make，一个defconfig配置代表一种BSP支持。Buildroot 本身不具备扩展能力，用户需要自己通过脚本来完成工作。这些列出来的特点，都是和Yocto不同的地方。

注意：Buildroot实际上使用Busybox来制作根文件系统。

1.2.2 `Yocto`

Yocto和Buildroot一样，是一套构建嵌入式系统的工具，但是两者的风格完全不同。

Yocto工程是通过一个个单独的包（meta）来维护，比如有的包负责核心，有的包负责外围。有的包用于跑Rockchip的芯片，有的包用于安装上weston, 有的包是则是用于跑debian，同样采用类似机制的nodejs，社区膨胀非常厉害，活跃度很高，每个人都可分享自己的成果到github上，这样的机制保证了我们可从互联网复用别人的工作成果，相当有价值。

相比Buildroot系统，Yocto有其更强的编译机制，比如第三方包的依赖和重编，都会自动处理。缺点相对复杂、需VPN网络。

Yocto是一个非常灵活的构建系统，允许用户使用shell和Python来处理各种特殊情况。目前，该系统主要针对国外客户。如果您需要更多关于Yocto的信息，请查看以下参考资料：

1.2.3 `Debian`

Debian是一种完全自由开放并广泛用于各种设备的Linux操作系统，选择Debian原因如下：

Debian是自由软件：Debian是由自由和开放源代码的软件组成，并将始终保持100%自由，每个人都能自由使用、修改，以及发布，大家可以基Rockchip构建的Debian系统进行二次开发；
Debian是一个基于Linux稳定且安全的的操作系统：Debian是一个广泛用于各种设备的操作系统，其使用范围包括笔记本计算机，台式机和服务器。自1993年以来，它的稳定性和可靠性就深受用户的喜爱。我们为每个软件包提供合理的默认配置，Debian开发人员会尽可能在其生命周期内为所有软件包提供安全更新；
Debian具有广泛的硬件支持：大多数硬件已获得Linux内核的支持。当自由软件无法提供足够的支持时，也可使用专用的硬件驱动程序。目前Rockchip RK3588/RK3568/RK3566/RK3399/RK3288等芯片已经适配并支持；
Debian提供平滑的更新：Debian以在其发行周期内轻松流畅地进行更新而闻名，不仅如此，还包括轻松升级到下一个大版本。Rockchip目前已从Debian Stretch(9)升级到Debian Buster(10)和Bullseye(11)版本；
Debian是许多其他发行版的种子和基础：许多非常受欢迎的Linux发行版，例如Ubuntu、Knoppix、PureOS、SteamOS以及 Tails，都选择了Debian作为它们的软件基础。Debian提供了所有工具，因此每个人都可以用能满足自己需求的软件包来扩展 Debian档案库中的软件包；
Debian项目是一个社区：Debian不只是一个Linux操作系统。该软件由来自世界各地的数百名志愿者共同制作。即使您不是一个程序员或系统管理员，也可以成为Debian社区的一员；

Rockchip定制版的Debian系统是通过Shell脚本来达到获取构建Linux Debian发行版源码，编译和安装适配Rockchip硬加速包的操作系统。

1.3 `SDK`软件框图

SDK软件框图如下图所示：

从下至上分为启动层、内核层、库、应用层四个层次。各层次内容如下：

启动层主要提供系统启动，如BootROM、U-Boot、ATF等相关支持；
内核层主要提供Linux Kernel的标准实现，Linux也是一个开放的操作系统，Rockchip平台的Linux核心为标准的Linux4.4/4.19/5.10内核，提供安全性，内存管理，进程管理，网络协议栈等基础支持；主要是通过Linux内核管理设备硬件资源，如CPU调度、缓存、内存、I/O等；
库层对应一般嵌入式系统，相当于中间件层次。包含了各种系统基础库，及第三方开源程序库支持，对应用层提供API接口，系统定制者和应用开发者可以基于Libraries层的API开发新的应用；
应用层主要是实现具体的产品功能及交互逻辑，需要一些系统基础库及第三方程序库支持，开发者可以开发实现自己的应用程序，提供系统各种能力给到最终用户。

SDK系统启动流程是指系统上电到系统启动完成的一个软件流程，下面是linux系统启动流程：

注意：

AP和MCU内部都有集成一个 BootROM，系统上电时先会运行BootROM代码，然后BootROM代码会探测外设存储器并加载Loader代码；
PreLoader 前有3个： miniloader（非开源）， uboot tpl和uboot spl loader；

1.4 `SDK`开发流程

Rockchip Linux系统是基于Buildroot/Yocto/Debian系统,,内核基于kernel 4.4/4.19/5.10开发，针对多种不同产品形态开发的SDK。可以基于本SDK，有效地实现系统定制和应用移植开发。

如图所示，开发者可以遵循上述开发流程，在本地快速构建Rockchip Linux系统的开发环境和编译代码。下面将简单介绍下该流程：

检查系统需求：在下载代码和编译前，需确保本地的开发设备能够满足需求，包括机器的硬件能力，软件系统，工具链等。目前SDK支持Linux操作系统环境下编译，并仅提供Linux环境下的工具链支持，其他如MacOS，Windows等系统暂不支持；
搭建编译环境：介绍开发机器需要安装的各种软件包和工具，详见第二节SDK开发坏境搭建。
选择设备：在开发过程中，需要开发者根据自己的需求，选择对应的硬件板型；
下载源代码：选定设备类型后，需要安装repo工具用于批量下载源代码；
系统定制：开发者可以根据使用的硬件板子、产品定义，定制u-boot、kernel及rootfs，详见第五节SDK开发；
编译与打包：介绍具备源代码后，选择产品及初始化相关的编译环境，而后执行编译命令，包括整体或模块编译以及编译清理等工作，进一步内容详见第三节SDK编译说明。
烧录并运行：继生成镜像文件后，将介绍如何烧录镜像并运行在硬件设备，进一步内容详见第四节SDK固件升级；

二、`SDK`开发环境搭建

2.1 概述

本节主要介绍了如何在本地搭建编译环境来编译Rockchip Linux SDK源代码，当前SDK只支持在Linux环境下编译和进行二次开发。

一个典型的嵌入式开发环境通常包括Linux服务器、PC和目标硬件版，典型开发环境如下图所示；

其中：

Linux服务器上建立交叉编译环境，为软件开发提供代码、更新下载和进行编译等服务；
PC和Linux服务器共享程序，并安装Putty或Minicom，通过网络远程登陆到Linux服务器，进行交叉编译，及代码的开发调试；
PC通过串口和USB与目标硬件板连接，可将编译后的镜像文件烧写到目标硬件板，并调试系统或应用程序。

2.2 源码获取

在一个大型项目中，一般会拆成多个子系统来分开管理，每一个子系统都对应着一个git仓库。但在拉取整个项目的时候就需要一个一个去拉取仓库，或者要写一个shell脚本去拉取，这样做可以，但略显笨拙。于是repo来拯救了我们，它是一个建立在git上的工具，本质其实是一个Python脚本，所以需要安装Python，像Android这样的系统也是用repo来管理的。

Rockchip Linux SDK的代码和相关文档被划分为了若干git仓库分别进行版本管理，开发者可以使用repo对这些git仓库进行统一的下载、提交、切换分支等操作。

获取Rockchip Linux软件包，需要有一个帐户访问Rockchip提供的源代码仓库。客户向瑞芯微技术窗口申请SDK，同步提供SSH公钥进行服务器认证授权，获得授权后即可同步代码。

请根据《Rockchip_User_Guide_SDK_Application_And_Synchronization_CN》文档说明操作，生成SSH公钥，发邮件至fae@rock-chips.com，申请开通SDK代码。该文档会在申请开通权限流程中，释放给客户使用。

作为一个用户这里我们大概率是无法直接申请开通SDK代码的，所以这里直接使用armsom开发板厂商提供的SDK源码；

这里我们从https://github.com/ArmSoM/armsom-rk3588-bsp下载SDK源码，命令如下：

drwxr-xr-x  9 root      root      4096  6月  9 12:59 yocto/

注意：这里我直接从开发板厂商获取了最新的代码。

除了文章最开介绍的目录外，Rockchip Linux SDK还包含如下内容：

build.sh：指向device/rockchip/common/scripts/build.sh， SDK编译脚本；
envsetup.sh ：指向buildroot/build/envsetup.sh，配置Buildroot编译环境脚本；

2.2.1 `u-boot`及`kernel`编译工具链

鉴于Rockchip Linux SDK目前只在Linux PC环境下编译，SDK提供了Linux下的交叉编译工具链。prebuilt目录下的工具链是u-boot和kernel使用；

对应版本：

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# prebuilts/gcc/linux-x86/aarch64/gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-gcc -v
......
gcc 版本 10.3.1 20210621 (GNU Toolchain for the A-profile Architecture 10.3-2021.07 (arm-10.29))

2.2.2 `rootfs`编译工具链

具体rootfs需要用各自对应的工具链，或者使用第三方工具链进行编译。

以Buildroo为例，具体参考：

buildroot/docs/manual/using-buildroot-toolchain.txt；
buildroot/docs/manual/adding-packages.txt。

2.3 `Linux`服务器搭建

2.3.1 `ubuntu 22.04`

这里我们使用ubuntu 22.04来进行编译，因为只有该版本及以上版本glibc才支持GLIBC_2.33、GLIBC_2.34版本；由于我之前在虚拟机搭建的ubuntu版本为20.04，因此这里需要对系统进行升级；

zhengyang@ubuntu:~/桌面$ sudo apt install update-manager-core

然后运行软件更新器：

主要：这里不要通过对glibc源码进行编译得到高版本的glibc，这种做法可能导致系统崩溃。

此外：硬盘空间大于40G，如果您进行多个构建，将需要更大的硬盘空间。

2.3.2 安装库和工具集

使用命令行进行设备开发时，可以通过以下步骤安装编译SDK需要的库和工具；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# sudo apt update
root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# sudo apt install git ssh make gcc libssl-dev \
liblz4-tool expect expect-dev 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 ncurses-dev \
libgucharmap-2-90-dev bzip2 expat gpgv2 cpp-aarch64-linux-gnu libgmp-dev \
libmpc-dev bc python-is-python3 python2

2.3.3 设置`DNS`支持`kgithub.com`

如果PC在编译Buildroot时无法访问Google网站，需设置DNS来支持使用国内镜像kgithub.com下载dl包。

sudo sed -i '$a 43.154.68.204\tkgithub.com' /etc/hosts
sudo sed -i '$a 43.155.83.75traw.kgithub.com objects.githubusercontent.kgithub.com' /etc/hosts

2.3.4 检查和升级主机的`python`版本

python要求安装python 3.6及以上版本，检查主机python版本：

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# python3 --version
Python 3.10.12

如果不满足python>=3.6版本的要求，可通过如下方式升级：

PYTHON3_VER=3.6.15
echo "wget
https://www.python.org/ftp/python/${PYTHON3_VER}/Python-${PYTHON3_VER}.tgz"
echo "tar xf Python-${PYTHON3_VER}.tgz"
echo "cd Python-${PYTHON3_VER}"
echo "sudo apt-get install libsqlite3-dev"
echo "./configure --enable-optimizations"
echo "sudo make install -j8"

2.3.5 检查和升级主机的`make`版本

make要求安装make 4.0及以上版本，检查主机make版本；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# make -v
GNU Make 4.3

如果不满足make>=4.0版本的要求，可通过如下方式升级：

sudo apt update && sudo apt install -y autoconf autopoint
git clone https://gitee.com/mirrors/make.git
cd make
git checkout 4.2
git am $BUILDROOT_DIR/package/make/*.patch
autoreconf -f -i
./configure
make make -j8
sudo install -m 0755 make /usr/bin/make

2.3.6 检查和升级主机的`lz4`版本

lz4要求安装1.7.3及以上版本，检查主机lz4版本

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# lz4 -v
*** LZ4 command line interface 64-bits v1.9.3, by Yann Collet ***
refusing to read from a console

如果不满足LZ4>=1.7.3版本的要求，可通过如下方式升级：

git clone https://gitee.com/mirrors/LZ4_old1.git
cd LZ4_old1
make
sudo make install
sudo install -m 0755 lz4 /usr/bin/lz4

三、`SDK`编译说明

3.1 `SDK`编译命令查看

首先通过help命令查看SDK编译命令：

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# make help
  menuconfig             - interactive curses-based configurator
  oldconfig              - resolve any unresolved symbols in .config
  syncconfig             - Same as oldconfig, but quietly, additionally update deps
  olddefconfig           - Same as syncconfig but sets new symbols to their default value
  savedefconfig          - Save current config to RK_DEFCONFIG (minimal config)
  clean                  - Cleanup
  ......

Default option is 'allsave'.

我们定位到build.sh脚本入口，当我们执行./build.sh <target>时将会执行如下代码；

if [ "$0" != "$BASH_SOURCE" ]; then
        # Sourced, executing it directly
        "$BASH_SOURCE" ${@:-shell}
elif [ "$0" == "$BASH_SOURCE" ]; then
        # Executed directly
        main $@
fi

$0代表脚本名，而$BASH_SOURCE代表脚本文件的路径，因此当执行./build.sh <target>时，$0和$BASH_SOURCE会相同。

因此执行main $@，将调用名为main的函数，并将所有传递给脚本的参数传递给main函数。

有关build.sh文件的分析参考最后一节内容。

3.2 `SDK`板级配置

具体板级配置说明如下，进入工程device/rockchip/rk3588目录

板级配置	说明
rockchip_rk3588_evb1_lp4_v10_defconfig	适用于RK3588 EVB1搭配LPDDR4开发板
rockchip_rk3588_evb3_lp5_v10_defconfig	适用于RK3588 EVB3 搭配 LPDDR5开发板
rockchip_rk3588_evb7_lp4_v10_defconfig	适用于RK3588 EVB7搭配LPDDR4开发板
rockchip_rk3588s_evb1_lp4x_v10_defconfig	适用于RK3588S EVB1搭配LPDDR4开发板
rockchip_rk3562_evb1_lp4x_v10_defconfig	适用于RK3562 EVB1搭配LPDDR4开发板
rockchip_rk3562_evb2_ddr4_v10_defconfig	适用于 RK3566 EVB2 搭配DDR4开发板
rockchip_rk3588_sige7_defconfig	适用于RK3355 Sige7开发板
......	......
rockchip_defconfig	默认配置, 具体会软链接到默认一个板级配置

可通过make lunch或者./build.sh lunch进行配置，比如rk3588芯片；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# ./build.sh lunch
Log saved at /work/sambashare/rk3588/armsom/armsom-rk3588-bsp/output/sessions/2024-06-10_22-25-38

Pick a defconfig:

1. rockchip_defconfig
2. rockchip_rk3588_evb1_lp4_v10_defconfig
3. rockchip_rk3588_evb7_v11_defconfig
4. rockchip_rk3588_sige7_defconfig
5. rockchip_rk3588s_evb1_lp4x_v10_defconfig
Which would you like? [1]:

比如这里我们选择4：

Which would you like? [1]: 4
Switching to defconfig: /work/sambashare/rk3588/armsom/armsom-rk3588-bsp/device/rockchip/.chip/rockchip_rk3588_sige7_defconfig

#
make: Leaving directory '/work/sambashare/rk3588/armsom/armsom-rk3588-bsp/device/rockchip/common'

这里生成了output/.config配置文件，内容如下：

#

#
RK_DEFCONFIG="/work/sambashare/rk3588/armsom/armsom-rk3588-bsp/device/rockchip/.chips/rk3588/rockchip_rk3588_sige7_defconfig"

# RK_ROOTFS_SYSTEM_DEBIAN is not set
# RK_ROOTFS_SYSTEM_YOCTO is not set
RK_ROOTFS_TYPE="ext4"
# RK_ROOTFS_INITRD is not set

......

3.3 配置不同启动/内核/系统等组件

SDK可通过make menuconfig进行相关配置，目前可配组件主要如下:

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# make menuconfig
(/work/sambashare/rk3588/armsom/armsom-rk3588-bsp/device/rockchip/.chips/rk3588/rockchip_rk
  Rootfs  --->
  Loader (u-boot)  --->
  RTOS  --->
  Kernel  --->
  Boot  --->
  Recovery (buildroot)  --->
  PCBA test (buildroot)  --->
  Security  --->
  Extra partitions  --->
  Firmware  --->
  Update (Update image, OTA and A/B)  --->
  Others configurations  --->

通过以上config，可选择不同rootfs/loader/kernel等配置，进行各种定制化编译。另外还带有强大命令行切换功能。

注意menuconfig配置之后，需要make savedefconfig保存配置；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# make savedefconfig

这里本质上就是修改output/.config文件。

3.4 全自动编译

进入工程根目录执行以下命令自动完成所有的编译，如果只编译模块代码（uboot，kernel，rootfs，recovery），运行：

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# ./build.sh all

输出内容如下：

从输出日志可以看出编译顺序，我们接下来依次介绍。

3.4.1 编译`kernel`

通过mk-fitimage.sh脚本生成boot.img位于kernel目录下；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ll kernel/boot.img
-rw-r--r-- 1 root root 37622272  6月 11 22:52 kernel/boot.img

3.4.2 编译`rootfs`

编译输出根文件系统rootfs.ext4位于output/rootfs目录下；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ll output/rootfs
lrwxrwxrwx 1 root root 42  6月 11 22:52 output/rootfs -> ../buildroot/output/rockchip_rk3588/images/
root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ll output/rootfs/
-rw-r--r-- 1 root root 615713280  6月 11 22:58 rootfs.cpio
-rw-r--r-- 1 root root 273882955  6月 11 22:59 rootfs.cpio.gz
-rw-r--r-- 1 root root 763363328  6月 11 22:59 rootfs.ext2
lrwxrwxrwx 1 root root        11  6月 11 22:59 rootfs.ext4 -> rootfs.ext2
-rw-r--r-- 1 root root 275013632  6月 11 22:59 rootfs.squashfs
-rw-r--r-- 1 root root 624517120  6月 11 22:59 rootfs.tar

系统默认是Buildroot，可以通过设置坏境变量RK_ROOTFS_SYSTEM指定不同rootfs。RK_ROOTFS_SYSTEM目前可设定三种系统：buildroot、debian、 yocto。

比如需要debain可以通过以下命令进行生成：

RK_ROOTFS_SYSTEM=debian ./build.sh all

3.4.3 编译`wifi/BT`模块

编译wifi/BT模块，并打包到根文件系统。

3.4.4 编译`recovery`

通过mk-recovery.sh脚本编译完成输出recovery.img，位于output/recovery目录下；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ll output/recovery
lrwxrwxrwx 1 root root 51  6月 11 22:59 output/recovery -> ../buildroot/output/rockchip_rk3588_recovery/images/
root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ll output/recovery/
-rw-r--r-- 1 root root 44296704  6月 11 23:00 recovery.img
-rw-r--r-- 1 root root 15763968  6月 11 23:00 rootfs.cpio
-rw-r--r-- 1 root root  6673958  6月 11 23:00 rootfs.cpio.gz
-rw-r--r-- 1 root root 43187200  6月 11 23:00 rootfs.ext2
lrwxrwxrwx 1 root root       11  6月 11 23:00 rootfs.ext4 -> rootfs.ext2
-rw-r--r-- 1 root root  6635520  6月 11 23:00 rootfs.squashfs
-rw-r--r-- 1 root root 16844800  6月 11 23:00 rootfs.tar

注意：recovery.img是由kernel+dtb+ramdisk组成的根文件系统，主要用于升级操作。

3.4.5 编译`u-boot`

通过mk-loader.sh脚本编译loader，编译完成生成uboot.img、rk3588_spl_loader_v1.13.112.bin位于u-boot目录下；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ll u-boot/uboot.img
-rw-r--r-- 1 root root 4194304  6月 11 23:00 u-boot/uboot.img
root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ll u-boot/rk3588_spl_loader_v1.13.112.bin
-rw-r--r-- 1 root root 471488  6月 11 23:00 u-boot/rk3588_spl_loader_v1.13.112.bin

3.4.6 打包分区镜像

通过mk-firmware.sh 脚本生成存放各个分区镜像的目录，位于output/firmware/目录下；

创建 parameter.txt链接文件，指向device/rockchip/.chips/rk3588/parameter.txt；
创建misc 分区镜像文件： misc.img；
创建oem分区镜像文件： oem.img；
创建userdata分区镜像文件： userdata.img；
创建MiniLoaderAll.bin链接文件，指向u-boot/rk3588_spl_loader_v1.13.112.bin；
创建uboot.img链接文件，指向u-boot/uboot.img；
创建boot.img链接文件，指向kernel/boot.img；
创建recovery.img链接文件，指向buildroot/output/rockchip_rk3588_recovery/images/recovery.img；
创建rootfs.img链接文件，指向buildroot/output/rockchip_rk3588/images/rootfs.img。

3.4.7 打包统一固件

打包各个分区镜像生成update.img；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ll output/update/
drwxr-xr-x 2 root root 4096  6月 11 23:00 Image/

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ll output/update/Image/
lrwxrwxrwx 1 root root        24  6月 11 23:00 boot.img -> ../../../kernel/boot.img
lrwxrwxrwx 1 root root        47  6月 11 23:00 MiniLoaderAll.bin -> ../../../u-boot/rk3588_spl_loader_v1.13.112.bin
lrwxrwxrwx 1 root root        23  6月 11 23:00 misc.img -> ../../firmware/misc.img
lrwxrwxrwx 1 root root        22  6月 11 23:00 oem.img -> ../../firmware/oem.img
-rw-r--r-- 1 root root       225  6月 11 23:00 package-file
lrwxrwxrwx 1 root root        52  6月 11 23:00 parameter.txt -> ../../../device/rockchip/.chips/rk3588/parameter.txt
lrwxrwxrwx 1 root root        70  6月 11 23:00 recovery.img -> ../../../buildroot/output/rockchip_rk3588_recovery/images/recovery.img
lrwxrwxrwx 1 root root        60  6月 11 23:00 rootfs.img -> ../../../buildroot/output/rockchip_rk3588/images/rootfs.ext2
lrwxrwxrwx 1 root root        25  6月 11 23:00 uboot.img -> ../../../u-boot/uboot.img
-rw-r--r-- 1 root root 872409674  6月 11 23:00 update.img
-rw-r--r-- 1 root root 871938052  6月 11 23:00 update.raw.img
lrwxrwxrwx 1 root root        27  6月 11 23:00 userdata.img -> ../../firmware/userdata.img

如果output/firmware/update.img文件不存在，会创建output/firmware/update.img链接文件指向output/update/Image/update.img。

3.4.8 清理磁盘

因此我们将根文件系统移动到/work/tftproot文件；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ cp buildroot/output/rockchip_rk3588/images/rootfs.ext2 /work/tftpboot/

该次编译会占用大量磁盘空间（我这里占用了40G+），导致剩余磁盘空间不充足，因此必要时候可以删除buildroot/output目录。

3.5 模块编译

3.5.1 `U-Boot`编译

编译命令如下：

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# ./build.sh uboot

输出详情如下：

编译后在buildroot/output/rockchip_rk3588_recovery/images/生成recovery.img；

注意：recovery.img是由kernel+dtb+ramdisk组成的根文件系统，主要用于升级操作。因此所以每次kernel更改，recovery.img是需要重新打包生成。

recovery重新打包的方法如下：

source buildroot/envsetup.sh
cd buildroot
make recovery-reconfigure
cd -
./build.sh recovery

注意：recovery是非必需的功能。

3.5.4 `Buildroot`编译

执行以下命令自动完成Buildroot的编译及打包：

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# ./build.sh buildroot

编译后在buildroot/output/rockchip_rk3588/images下生成不同格式的镜像, 默认使用rootfs.ext4格式。

由于全自动编译默认系统就是Buildroot，这里我就不重新编译了；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ll buildroot/output/rockchip_rk3588/images/
-rw-r--r-- 1 root root 615713280  6月 11 22:58 rootfs.cpio
-rw-r--r-- 1 root root 273882955  6月 11 22:59 rootfs.cpio.gz
-rw-r--r-- 1 root root 763363328  6月 11 22:59 rootfs.ext2
lrwxrwxrwx 1 root root        11  6月 11 22:59 rootfs.ext4 -> rootfs.ext2
-rw-r--r-- 1 root root 275013632  6月 11 22:59 rootfs.squashfs
-rw-r--r-- 1 root root 624517120  6月 11 22:59 rootfs.tar

其中：rockdev/目录下的rootfs.img指向了buildroot/output/rockchip_rk3588/images/rootfs.ext2。

3.5.5 `Debian`编译

需要预先安装以下相关依赖包:

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# cd debian
root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# sudo apt install binfmt-support qemu-user-static live-build
root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# sudo dpkg -i ubuntu-build-service/packages/*
root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# sudo apt install -f

执行以下命令自动完成Debian的编译及打包：

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# ./build.sh debian

输出详情如下：

该次编译会重新编译内核和根文件系统。耐心等待1个小时，与buildroot编译类似，编译完成我们在rockdev 目录下可以看到各个分区镜像；

可以看到该次编译重新生成了boot.img、rootfs.img。此外由于我们执行了./build.sh debian，此时output/.config中默认系统已经设置为了debian。

编译完成会在debian目录下生成：linaro-buster-alip-xxxxx-1.tar.gz（xxxxx 表示生成时间戳)。

因此我们将debian根文件系统移动到/work/tftproot文件；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ mv debian/linaro-rootfs.img /work/tftpboot/

3.5.6 `Yocto`编译

执行以下命令自动完成Yocto的编译及打包：

 root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp# ./build.sh yocto

编译后在yocto目录build/lastest下生成rootfs.img。

3.5.7 打包分区镜像

执行以下命令更新output/firmware/下各个分区镜像；

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ./build.sh firmware

查看目录：

root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ll rockdev/

四、`SDK`固件升级

RK3588有两种工作模式，

工作模式	Normal 模式	升级模式
启动介质	eMMC 接口/SDMMC 接口
描述	Normal 模式就是正常的启动过程，各个组件依次加载，正常进入系统。	目前支持3种升级模式，各有优缺点： 1. Maskrom升级模式 2. Loader 升级模式 3. SD 升级模式

一般情况下，开机直接进入Normal模式正常启动系统。
