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 splloader；
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：

......
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 \

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

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。

3.3 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

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。

-rw-r--r-- 1 root root 4472832 6月 11 23:00 userdata.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/

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

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 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 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

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：

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。
其中升级模式中，不同升级模式之间的对比：
| 升级模式 | Maskrom升级模式 | Loader 升级模式 | SD 升级模式 |
|---|---|---|---|
| 简单描述 | 1. 使用USB线将主板连接到电脑上； 2. 硬件操作使板子进入升级模式； 3. 在PC上使用USB升级单板固件。 |
1. 使用USB线将主板连接到电脑上； 2. 软件或按键操作使板子进入升级模式； 3. 在PC上使用USB升级单板固件。 |
1. 通过升级卡制作工具，将MicroSD卡制作为升级卡； 2. 将升级卡插入主板，上电开机，机器自动执行升级。 |
| 连接方式 | USB | USB | TF卡（少数为SD卡槽） |
| 升级工具 Windows PC Linux PC | Windows 上升级固件 Linux 上升级固件 |
Windows 上升级固件 Linux 上升级固件 |
Windows 上制作升级卡 不支持 |
| 进入方法 | 需要硬件操作 | 按键或软件进入（在串口或 ADB 命令行模式下，输入 reboot loader 命令） | 上电直接进入 |
| 使用条件 | 硬件操作进入 | 能正常使用uboot | 无 |
| 使用场景推荐 | 1. 当板子无法正常启动时候； 2. 在切换烧写Linux和Android固件的情况下。 |
1. 有完整uboot或能正常进入系统； 2. 需要单独烧写分区(uboot或boot分区等)。 |
1. 工人操作方便，适合产品批量生产时候； 2. 产品定型后升级，方便最终客户操作。 |
| 优点 | 1. 最基本的烧写方式； 2. 非固件和硬件问题，一般都能成功烧写； 3. 不需要uboot支持，拯救变砖的单板； 4. 支持跨系统升级(Linux和安卓等)。 |
1. 烧写效果Maskrom升级模式差不多； 2. 能单独烧写分区； 3. 进入Loader模式方便。 |
1. 操作方便，只需插卡启动； 2.集合了Maskrom升级模式的优点。 |
| 缺点 | 1. 进入方式麻烦，不适难拆除外壳的产品； 2. 烧写分区表麻烦，较难单独烧写分区； 3. 需要完全擦除设备再烧写。 |
1. 需要完整的Loader(通常指uboot)； 2. 跨系统升级需要完全擦除设备再烧写。 |
1. 需要合成完整固件。 |
4.1 Windows刷机
Winodws刷机我们有两种方式：
- 采用
SD升级模式： RKDevTool烧写固件到eMMC；
4.1.1 SD卡升级模式
这里我们就采用SD升级模式来将我们全自动编译的镜像文件烧录到eMMC，具体可以参考《若固件大于4G的SD升级卡制作教程》。
(1) 准备工作：
- 烧写工具下载：将
tools/windows目录下的SDDiskTool_v1.76.zip工具上传到Windows系统，并进行解压； - 下载需要升级的统一固件：将
buildroot系统统一镜像rockdev/update.img上传到Windows系统； - 将
MicroSD通过读卡器插入PC； - 将开发板连接到
HDMI显示屏；
(2) 以管理员身份运行SD_Firmware_Tool.exe，勾选固件升级框，选择正确的可移动磁盘设备和升级固件；
(3) 点击开始创建之后，等待创建结束；烧录完成后，可以查看MicroSD的内容：
(4) 取出MicroSD卡，插入开发板的MicroSD卡插槽，对主板上电开机，主板自动开始升级。
注意：由于我们无法可视化查看升级进度，因此此处需要耐心等待3分钟。
(5) 升级完成后，取出MicroSD卡，开发板自动重启，显示屏显示如下；
关于buildroot系统简单测试可以参考后续《Rockchip RK3588 - Rockchip Linux SDK Buildroot文件系统构建》。
4.1.2 RKDevTool烧写固件到eMMC

该方式我们在前面的文章中已经介绍了，具体可以参考《Rockchip RK3588 - NanoPC-T6开发板介绍》第2.3节。
4.2 Linux刷机
Linux下的烧写工具位于tools/linux目录下(Linux_Upgrade_Tool工具版本需要V2.17或以上)，请确认你
的板子连接到Maskrom/Loader rockusb；

比如buildroot系统编译生成的固件在rockdev目录下：
root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ll rockdev/
lrwxrwxrwx 1 root root 21 6月 11 22:52 boot.img -> ../../kernel/boot.img
lrwxrwxrwx 1 root root 44 6月 11 23:00 MiniLoaderAll.bin -> ../../u-boot/rk3588_spl_loader_v1.13.112.bin
-rw-r--r-- 1 root root 49152 6月 11 23:00 misc.img
-rw-r--r-- 1 root root 17457152 6月 11 23:00 oem.img
lrwxrwxrwx 1 root root 49 6月 11 23:00 parameter.txt -> ../../device/rockchip/.chips/rk3588/parameter.txt
lrwxrwxrwx 1 root root 67 6月 11 23:00 recovery.img -> ../../buildroot/output/rockchip_rk3588_recovery/images/recovery.img
lrwxrwxrwx 1 root root 57 6月 11 22:59 rootfs.img -> ../../buildroot/output/rockchip_rk3588/images/rootfs.ext2
lrwxrwxrwx 1 root root 22 6月 11 23:00 uboot.img -> ../../u-boot/uboot.img
lrwxrwxrwx 1 root root 26 6月 11 23:00 update.img -> ../update/Image/update.img
-rw-r--r-- 1 root root 4472832 6月 11 23:00 userdata.img
升级命令如下：
root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ ./rkflash.sh
这里rkflash.sh脚本实际上就是使用upgrade_tool命令烧写各个分区，比如核心脚本：
if [ ! -n "$1" ];then
echo "flash all images as default"
FLASH_TYPE=all
else
FLASH_TYPE="$1"
fi
if [ $FLASH_TYPE = all ]
then
$UPGRADETOOL ul -noreset $LOADER
$UPGRADETOOL di -p $PARAMETER
$UPGRADETOOL di -uboot $UBOOT
$UPGRADETOOL di -trust $TRUST
$UPGRADETOOL di -b $BOOT
$UPGRADETOOL di -r $RECOVERY
$UPGRADETOOL di -m $MISC
$UPGRADETOOL di -oem $OEM
$UPGRADETOOL di -userdata $USERDATA
$UPGRADETOOL di -rootfs $ROOTFS
$UPGRADETOOL rd
fi
当然也可以直接使用upgrade_tool命令一一烧写各个分区镜像或者打包后完整的固件，具体操作可以参考：《Linux下烧录固件》。

其中：
uboot分区：供uboot编译出来的uboot.img；misc分区：引导参数分区，供misc.img，给recovery使用；boot分区：供kernel编译出来的boot.img（kernel + dtb，对于该类型镜像uboot需要采用distro_boo extlinux引导方式）；recovery分区：供recovery编译出的recovery.img（kernel + dtb + ramdisk，recovery系统使用镜像文件）；backup分区：预留，暂时没有用；rootfs分区：供buildroot、debian或yocto编出来的rootfs.img；oem分区：给厂家使用，存放厂家的APP或数据。挂载在/oem目录；userdata分区：供APP临时生成文件或给最终用户使用，挂载在/userdata目录下。
4.4 dd烧录分区
我们也可以通过dd命令烧写各个分区镜像；
dd if=uboot.img of=/dev/mmcblk0p1 bs=1M
dd if=boot.img of=/dev/mmcblk0p3 bs=1M
dd if=rootfs.img of=/dev/mmcblk0p6 bs=1M
dd if=oem.img of=/dev/mmcblk0p7 bs=1M
dd if=userdata.img of=/dev/mmcblk0p8 bs=1M
4.4.1 烧录userdata.img
如果要更新userdata.img，具体流程如下。
(1) 首先将userdata.img拷贝到tftp根目录下（/work/tftpboot/）：
root@ubuntu:/work/sambashare/rk3588/armsom/armsom-rk3588-bsp$ cp rockdev/userdata.img /work/tftpboot/
busybox内置tftp，可以直接从ubuntu宿主机tftp服务器下载文件：
root@rk3588-buildroot:/opt# tftp -g -l userdata.img 192.168.0.200
从ubuntu中的tftp根目录下（/work/tftpboot/），下载文件userdata.img。
root@rk3588-buildroot:/opt# ls -l
drwxr-xr-x 6 root root 4096 Jun 11 14:52 unixbench
-rw-r--r-- 1 root root 4472832 Jun 16 04:51 userdata.img
(2) 接着我们在/userdata目录下创建一个test.txt文件；
root@rk3588-buildroot:/opt# touch /userdata/test.txt
root@rk3588-buildroot:/opt# ls -l /userdata/
total 279
-rw-r--r-- 1 root root 87402 Jun 9 04:58 200frames_count.h264
-rw-r--r-- 1 root root 81582 Jun 9 04:58 belle-nuit-testchart-1080p.png
drwx------ 2 root root 12288 Jun 11 15:00 lost+found
-rw-r--r-- 1 root root 101760 Jun 9 04:58 piano2-CoolEdit.mp3
-rw-r--r-- 1 root root 0 Jun 16 04:31 test.txt
(3) 重新烧写userdata分区：
root@rk3588-buildroot:/opt# dd if=userdata.img of=/dev/mmcblk0p8 bs=1M
4+1 records in
4+1 records out
4472832 bytes (4.5 MB, 4.3 MiB) copied, 0.00915314 s, 489 MB/s
再次查看/userdata：
root@rk3588-buildroot:/opt# ls -l /userdata/
total 278
-rw-r--r-- 1 root root 87402 Jun 9 04:58 200frames_count.h264
-rw-r--r-- 1 root root 81582 Jun 9 04:58 belle-nuit-testchart-1080p.png
drwx------ 2 root root 12288 Jun 11 15:00 lost+found
-rw-r--r-- 1 root root 101760 Jun 9 04:58 piano2-CoolEdit.mp3
可以看到该目录下已经不存在test.txt文件了，说明分区烧录成功了。
4.4.2 烧录debian根文件系统
从ubuntu中的tftp根目录下（/work/tftpboot/），下载文件linaro-rootfs.img。
# 耐心等待50分钟
root@rk3588-buildroot:/opt# tftp -g -l linaro-rootfs.img 192.168.0.200
root@rk3588-buildroot:/opt# ls -l
-rw-r--r-- 1 root root 3313500160 Jun 16 15:40 linaro-rootfs.img
drwxr-xr-x 6 root root 4096 Jun 11 14:52 unixbench
-rw-r--r-- 1 root root 4472832 Jun 16 04:51 userdata.img
重新烧写rootfs分区：
root@rk3588-buildroot:/opt# dd if=linaro-rootfs.img of=/dev/mmcblk0p6 bs=1M
3160+0 records in
3160+0 records out
3313500160 bytes (3.3 GB, 3.1 GiB) copied, 13.3972 s, 247 MB/s
4.5 debain系统测试
4.5.1 查看系统
重启开发板，查看系统信息；
root@armsom-sige7:/# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 11 (bullseye)
Release: 11
Codename: bullseye
4.5.2 设置DNS服务器
设置DNS服务器：
root@armsom-sige7:/# sudo vi /etc/resolv.conf
# 追加
nameserver 114.114.114.114
root@armsom-sige7:/# sudo /etc/init.d/networking restart
4.5.3 查看磁盘空间
这里我们可以通过df -hT查看磁盘空间信息；
root@armsom-sige7:/# df -hT
文件系统 类型 容量 已用 可用 已用% 挂载点
/dev/root ext4 3.0G 3.0G 0 100% /
devtmpfs devtmpfs 3.9G 0 3.9G 0% /dev
tmpfs tmpfs 3.9G 0 3.9G 0% /dev/shm
tmpfs tmpfs 1.6G 2.1M 1.6G 1% /run
tmpfs tmpfs 5.0M 4.0K 5.0M 1% /run/lock
/dev/mmcblk0p7 ext4 121M 12M 103M 11% /oem
/dev/mmcblk0p8 ext4 43G 288K 42G 1% /userdata
tmpfs tmpfs 793M 28K 793M 1% /run/user/1000
tmpfs tmpfs 793M 28K 793M 1% /run/user/110
这里我们可以看到根目录挂载在/dev/root设备节点上，文件系统格式是ext4，/dev/root其实就是/dev/mmcblk0p6，也就是eMMC设备的rootfs分区。
但是为什么这里看到的/dev/root大小只有3.0G呢？rootfs分区我们不是指定了14G么？这主要是因为我们的根文件系统镜像制作的就是那么大，剩余的分区空间并未使用。
4.5.4 resize2fs扩容
文件系统能通过扩充容量来利用其分区后的空闲空间。通常情况下，这甚至可以在文件系统被挂载时进行。
这里我们可以通过resize2fs指令进行扩容：
root@armsom-sige7:/# resize2fs /dev/mmcblk0p6
resize2fs 1.46.2 (28-Feb-2021)
Filesystem at /dev/mmcblk0p6 is mounted on /; on-line resizing required
[ 1881.827893] EXT4-fs warning (device mmcblk0p6): ext4_resize_begin:82: There are errors in the filesystem, so online resizing is not allowed
old_desc_blocks = 1, new_desc_blocks = 2
resize2fs: Permission denied to resize filesystem
很明显扩容失败了，主要是因为该设备被挂载到/，内核不支持在线调整已挂载文件系统的大小。
为此我们制作一个SD卡启动盘，使开发板从SD启动，此时eMMC设备节点为/dev/mmcblk0。
这里我们可以通过resize2fs指令进行扩容：
zhengyang@armsom-sige7:~$ sudo e2fsck -f /dev/mmcblk0p6
e2fsck 1.46.5 (30-Dec-2021)
/dev/mmcblk0p6: recovering journal
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 3A: Optimizing directories
Pass 4: Checking reference counts
Pass 5: Checking group summary information
Free blocks count wrong (32132, counted=9666).
Fix<y>? yes
Free inodes count wrong (130235, counted=129568).
Fix<y>? yes
/dev/mmcblk0p6: ***** FILE SYSTEM WAS MODIFIED *****
/dev/mmcblk0p6: 72832/202400 files (0.2% non-contiguous), 799294/808960 blocks
zhengyang@armsom-sige7:~$ sudo resize2fs /dev/mmcblk0p6
resize2fs 1.46.5 (30-Dec-2021)
Resizing the filesystem on /dev/mmcblk0p6 to 3670016 (4k) blocks.
The filesystem on /dev/mmcblk0p6 is now 3670016 (4k) blocks long.
开发板拔掉SD卡，重启启动开发板，稍等一会，显示器上会进入debain桌面系统（如果不扩容的话，由于/目录没有磁盘空间了，也就进不了debain桌面环境的）；
注意：此时需要进行应用程序 --> 设置 --> 显示进行配置，关闭调用DSI-1。
再次查看磁盘空间：
root@armsom-sige7:/# df -hT
文件系统 类型 容量 已用 可用 已用% 挂载点
/dev/root ext4 14G 3.0G 11G 23% /
devtmpfs devtmpfs 3.9G 8.0K 3.9G 1% /dev
tmpfs tmpfs 3.9G 0 3.9G 0% /dev/shm
tmpfs tmpfs 1.6G 2.2M 1.6G 1% /run
tmpfs tmpfs 5.0M 4.0K 5.0M 1% /run/lock
/dev/mmcblk0p7 ext4 121M 12M 103M 11% /oem
/dev/mmcblk0p8 ext4 43G 288K 42G 1% /userdata
tmpfs tmpfs 793M 40K 793M 1% /run/user/1000
