首先感谢P3TERX、coolsnowwolf和siwind三位大佬的Aciton库、源码和dts
Action库 https://github.com/P3TERX/Actions-OpenWrt
源码 https://github.com/coolsnowwolf/lede
dts https://github.com/siwind/openwrt/tree/master/target/linux/ramips/dts
1.因为源码中没有e8820v2的dts文件和机型定义，所以首先要将Action和源码folk，然后下载siwind大佬制作的dts文件，链接上面已经给到，将dts稍加编辑后加入到/target/linux/ramips/dts内，也可直接下载本仓库内的dts。

};编辑/target/linux/ramips/image下的mt7621.mk，在最后添加e8820v2的机型定义，如下:
define Device/zte_e8820v2
$(Device/dsa-migration)
$(Device/uimage-lzma-loader)
IMAGE_SIZE := 16064k
DEVICE_VENDOR := ZTE
DEVICE_MODEL := E8820V2
DEVICE_COMPAT_VERSION := 2.0
DEVICE_PACKAGES := kmod-mt7603 kmod-mt76x2 kmod-usb2 \
kmod-usb-ledtrig-usbport kmod-cfg80211 kmod-mac80211
TARGET_DEVICES += zte_e8820v2
—————————————————————————————————————————————————————————————— PS:如果是硬改的32m的rom，需要修改dts和机型代码，dts文件中这处字段需要修改：
partition@50000 {
compatible = "denx,uimage";
label = "firmware";
reg = <0x50000 0x1fb0000>;
};
# 将0xfb0000修改为0x1fb0000机型代码修改如下：
define Device/zte_e8820v2
$(Device/dsa-migration)
$(Device/uimage-lzma-loader)
IMAGE_SIZE := 32448k
DEVICE_VENDOR := ZTE
DEVICE_MODEL := E8820V2
DEVICE_COMPAT_VERSION := 2.0
DEVICE_PACKAGES := kmod-mt7603 kmod-mt76x2 kmod-usb2 \
kmod-cfg80211 kmod-mac80211
TARGET_DEVICES += zte_e8820v2
# 将IMAGE_SIZE的值修改为32448k由于e8820v2只支持一个gmac，所以开不开交换机无所谓，为了显得全功能一点还是开一下，编辑/target/linux/ramips/mt7621/base-files/etc/board.d/02_network如下：
ramips_setup_interfaces()
......
zte,e8820v2)
ucidef_add_switch "switch0" \
"0:lan:4" "1:lan:3" "2:lan:2" "3:lan:1" "4:wan:5" "6@eth0"
;;
......
ramips_setup_macs()
......
zte,e8820v2)
lan_mac=$(cat /sys/class/net/eth0/address)
wan_mac=$(mtd_get_mac_binary factory 0xe006)

修改/.github/workflows/build-openwrt.yml文件:

REPO_BRANCH: master
FEEDS_CONF: feeds.conf.default
CONFIG_FILE: .config

# REPO_URL的值修改为你的源码仓库地址
# CONFIG_FILE的值修改为你的配置文件名-
首先装好 Linux 系统，推荐 Debian 11 或 Ubuntu LTS

下载你修改后的源代码，更新 feeds 并选择配置
git clone https://github.com/yourid/lede cd lede ./scripts/feeds update -a ./scripts/feeds install -a make menuconfig
PS： OpenWrt编译 LuCI -> Applications 添加插件应用说明 https://www.right.com.cn/forum/thread-344825-1-1.html openwrt添加usb功能（不知为何，e8820需要选择usb3） https://www.right.com.cn/FORUM/forum.php?mod=viewthread&tid=3064424 openwrt支持网卡 http://www.mlapp.cn/1009.html
- 由于我们是利用Aciton进行云编译，所以在make menuconfig之后，只要把lede文件夹下的.config文件上传到Actions-OpenWrt上并覆盖原文件就行了（也可重命名，但重命名后要在build-openwrt.yml重新指定），之后就是常规的云编译步骤。
