针对Cool Pi 4B主板，如需更新u-boot操作如下：

0823版本请升级到0904

1. 下载0904版本bin文件
   uboot.zip

2. 解压zip，将bin文件拷贝到U盘或Tf卡根目录

3. 将U盘或Tf卡插入主板，连接Debug串口到PC电脑，打开串口终端工具，主板通电，连续输入大写CP中止u-boot自动启动

   备注：请注意U盘启动或升级仅支持插入USB3 下层端口

4. 在u-boot shell命令行窗口，
   针对串口输出信息如下的主板

A) 如果是从U盘导入文件升级步骤
usb reset
load usb 0:1 0x800000 uboot.img
mtd erase nor0 0x200000 0x500000
mtd write nor0 0x800000 0x200000 0x500000
擦除与写入过程请勿断电或重启

B) 如果是从TF卡导入文件升级步骤
mmc dev 1
load mmc 1:1 0x800000 uboot.img
mtd erase nor0 0x200000 0x500000

also use onedrive link(https://1drv.ms/u/s!AhSBNZjrDPlSanDDQF7WowYhiz8?e=lRpMrk). And then the top u3 port is used for adb debug.

@retroman
hi, thanks for your advice. This work will be long and continue. We need more community friends to participate.

用户基于我们发布是镜像系统，安装软件或进行其他配置之后，如果想备份系统，有很多方法可以实现，我这里提供一个比较简单的思路供大家参考。

前置条件：

1. 假如您手边有一张已经做好系统的TF卡
2. 各种改动后的EMMC系统

核心操作步骤：

1. 从EMMC启动系统，登陆桌面并打开终端命令行更改卷标

sudo su
fatlabel /dev/mmcblk0p1 emmc-boot
e2label /dev/mmcblk0p2 emmc-rootfs

vim /boot/firmware/cmdline.txt
将writable替换为emmc-rootfs  然后保存退出

vim /etc/fstab
将writable替换为emmc-rootfs  然后保存退出

sync;

2. 插入TF卡，重启系统

3. 默认优先从TF卡引导系统，进入系统之后，可以挂载EMMC分区进行备份压缩

使用1017镜像版本，需要额外执行如下指令完成环境搭建

sudo su
apt-mark unhold libssl1.1 libdpkg-perl libc-dev-bin libc6 libc6-dev
apt update
apt install gcc make git python libncurses5-dev openssl libssl-dev build-essential pkg-config libc6-dev bison flex

下载内核本地编译

mkdir test;cd test
git clone https://gitee.com/yanyitech/coolpi-kernel.git
cd coolpi-kernel
./build-kernel.sh
编译完成，在out目录生成内核二进制文件、设备树以及驱动包
