@xingzhan2012 如需要，后续可以补上

uos 统信专业版

@edwardzhou 提示在显示器输出进度，当然也可以修改console切换到串口输出

@edwardzhou 用U盘备份安装系统，不用考虑移除emmc

@xingzhan2012 said in Cool pi 4B & CM5 探索快速安装系统新方法:

@大法师 牛逼，也就是U盘里创建一个backpu文件夹，插在USB口上，开机自动备份到backup文件夹中。 U盘中创建一个install文件夹，开机自动将install中的系统刷入emmc中。Cool Pi 4B Linux System Backup.iso中的文件替换掉系统中的/boot/firmware 文件夹中的文件是吧。这些启动文件是ubuntu22.04系统的么？是和系统版本无关么？

安装备份操作，与rootfs系统无关，可以是任意制作的linux 根文件系统。这种方式适合开发者调试，可以是openwrt或buildroot或yocto等等

@xingzhan2012
备份还原操作，可以同一个U盘，把backup iso中的initrd.img拷贝到install iso 中，重命名为initrd-backup.img。

想加载哪个功能，直接修改extlinux.conf启动哪个文件即可。当然配套backup目录可以直接重命名为install，更直接了

@xingzhan2012
太自动化会引起误操作。确实有必要备份重新安装，也不差一次拷贝动作

@tonyone0902
vim /boot/firmware/config.txt 一样修改dtb文件名试下。你的机器是什么时间收到的，早期的loader不识别extlinux.conf

另外查看下 ls -l /sys/class/drm/

@xingzhan2012 像Windows一样自动安装、自动备份，一个U盘搞定，无需额外操作

@tonyone0902
系统终端输入dmesg > kernel.log

把kernel.log发上来看下。

@xingzhan2012
欢迎验证系统备份功能

假定手上有两个U盘，一个制作为系统初始化安装U盘A，另一个制作为系统备份U盘B。

当用户在系统中安装或修改各种配置操作后，如需要备份保存系统，那么请关机，插入备份U盘B，开机自动完成备份操作（备份文件在backup目录）。

当用户想恢复备份的系统到coolpi 4b板载的存储emmc，那么可以将备份U盘B中的backup目录内容拷贝到安装U盘A install目录（请注意先删除install目录文件），插入安装U盘A，开机自动完成系统安装操作。

5寸电容触摸屏切换操作参考，使用ubuntu 22.04 20230306版本

需要切换使用rk3588s-cp4-dsi.dtb文件

@xingzhan2012 我们调试了一款OV5647。摄像头型号比较多，调试周期较长，我们会再选一些通用型号匹配验证。谢谢

@xingzhan2012 好的，谢谢建议

@顾真牛 预留的插槽，支持这个配件。据说单模组有26T算力

@顾真牛 等你的好消息

补充内核编译操作说明（如下以coolpi 4b ubuntu22.04 0306系统版本为例）：

首先下载内核源码

coolpi@coolpi:~$ git clone https://github.com/yanyitech/coolpi-kernel.git
Cloning into 'coolpi-kernel'...
remote: Enumerating objects: 8550563, done.
remote: Counting objects: 100% (5962/5962), done.

coolpi@coolpi:~$

额外安装组件包

coolpi@coolpi:~$ sudo apt install -y flex bison libssl-dev
coolpi@coolpi:~$ sudo ln -sf /usr/bin/python3 /usr/bin/python

开始编译内核

coolpi@coolpi:~$ cd coolpi-kernel
coolpi@coolpi:~/coolpi-kernel$ ./build-kernel.sh cp4b

对广大用户而言，系统装机更多的方式就是使用U盘，做个启动引导盘，刷遍无数机。

Cool pi 4b已支持此种安装方法，ISO下载

windows 安装制作刷机工具
Rufus: The Reliable USB Formatting Utility

工具执行页面

如下图片为CM5 EVB U盘内容，用户可以任意替换install目录中的rootfs.tar.gz

安装过程进度可视化，连接HDMI显示器参数配置

全自动刷机，完成后自动关机，请移除u盘后再开机。

刷机过程优先刷emmc存储，如未接emmc，那么将刷到tf卡，如果也没插tf卡…

fedora37 with cool pi 4b sbc board preview

@xingzhan2012 什么现象拍照看下，抓一些系统log，系统引导盘是emmc or tf

1. Update to support two USB3 interface USB hard drive boot support.
2. Update fixes an abnormal offline flash startup problem.
3. Increase support press power key to switch to maskrom function when system boot.

This topic is specifically designed to describe cool pi 4b loader version updates.

Erase partitions

Tf card:
sudo wipefs -a -f /dev/mmcblk1

EMMC:
sudo wipefs -a -f /dev/mmcblk0

@xingzhan2012 可以用cool pi ubuntu系统，直接dd 刷系统到其他存储介质，比如emmc

@AugustRobot_Zou okay!
