@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.

Checking objects: 100% (33554432/33554432), done.
Updating files: 100% (87196/87196), 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

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…

@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.

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!

所有的底层封装操作都是基于访问/sys/class/gpio/

@jugg 这个建议不错，需要做这类的参考文档

上述环境操作不适用于新的镜像版本。

@jugg
刷一次系统，原系统就被清除了。buildroot也是一种系统构建工具

@MSUMMERS999
Please confirm the system info, which firmware image be used. You can also download the latest firmware through the onedrive link OneDrive, and the burning method is consistent with the raspberry pi.
