[移动开发]RK3568 Android固件介绍、固件烧录、开机进系统

固件介绍

编译生成的固件在rockdev/Image-rk3568_r目录下，包含如下文件：
baseparameter.img：
boot-debug.img：//usr固件往往没有root权限，此时可以烧它以进行root权限操作
boot.img? ?//包含了kernel.img、resource.img、ramdisk，但Android不能直接烧kernel.img和resource.img了，取而代之的是boot.img。需要使用build.sh -K 命令来编译 kernel从而得到boot.img。

config.cfg? ?//烧写工具的配置文件，可以直接导入烧写工具显示需要烧写的选项
dtbo.img? //由dts编译得到，修改了dts将会编到这里
MiniLoaderAll.bin? //很底层的loader程序，包含一级loader
misc.img? //包含recovery-wipe开机标识信息，烧写它后会进行recovery
parameter.txt? ?//分区表
pcba_small_misc.img //包含pcba开机标识信息，烧写后会进入简易版pcba模式
pcba_whole_misc.img //包含pcba开机标识信息，烧写后会进入完整版pcba模式
recovery.img? //包含了recovery-ramdis、kernel、dtb、resource等，是一个精简版的小系统。完整烧录固件后第一次开机或者从未正常进系统时? 开机要先跑这个；正常进过系统后再开机就不会跑这里了，在某些条件如进recovery才会跑这里。所以，当遇到烧录后无法正常开机，我们改了kernel，则一定要记得烧recovery.img和boot.img 或者全烧。
resource.img? //开机logo、开机充电logo等资源
super.img??//包含odm、product、vendor、system、system_ext分区内容；所以改了Android系统层要烧这个
uboot.img?? //uboot
update.img? //这是由零散固件打包而成的
vbmeta.img?? //包含avb校验信息，用于AVB校验

我们可以烧分散的img：（红色部分）

也可以烧update.img，等同于全烧。

注：(trust.img 包含BL31、BL32 ，RK3566/RK3568没生成这个，所以不需要烧写trust.img了)

安装支持RK3568的USB驱动

安装文件在SDK/RKTools/windows/DriverAssitant_v5.1.1.zip

如果以前已安装过旧版的驱动，则需更新，先卸载再安装即可。

新版驱动支持新型号芯片也兼容旧芯片的。

烧录固件前，最好先确认一下手上的板子硬件是否正常

烧录固件前，如果板子已烧录过别人的固件，先确认一下板子能否正常开机、常见模块如屏、TP、HDMI等是否正常；接串口打印看能否正常抓log；看ADB功能是否正常。

固件烧录用到的工具及烧录注意事项

SDK/RKTools/windows/AndroidTool/RKDevTool_Release_v2.84.zip

烧录RK3568 Android11的固件，要用v2.84版。新版工具支持新型号芯片也兼容旧芯片的。

此工具免安装，解压，双击?RKDevTool.exe 直接运行即可。

此工具有三个界面：

烧录分散固件的界面：

一般先选parameter，工具由parameter.txt知道要烧哪些分区及分区表是怎样的。

选了不同的parameter.txt，工具界面会变的。

?烧录update.img固件界面：

注：烧分散固件或统一固件都要在loader模式或maskroom模式下才能烧。

可以由adb模式切换到loader模式；

白片会进maskroom模式；或者短接板子触点进maskroom；

在loader模式下可以全烧也可烧几个需要的分区（一般parameter也是要烧的）。

maskroom模式一定要全烧，不能烧部分。

?高级功能界面，如固件解包、读取各种信息、从机器中导出某个分区镜像、擦除EMMC中的某一部分等：

上电开机

烧完固件后 PC工具会触发板子自动开机

看log

通过top看有哪些进程，判断系统已经起来。

看PC有没有识别到ADB设备。

第一次烧录会先执行recovery，再跑普通模式的uboot 、kernel。重刷了misc.img 后也会先跑一次recovery 再跑普通模式的uboot 、kernel。

开机log走读

第一次开机

\?
烧完固件自动重启，先执行一次recovery
先初始化DDR，打印DDR相关信息，然后DDR逐步升频一个个try：

如果容量不对? 或者跑到某些频点就失败，则需检查硬件DDR部分。
