中兴E8820S及兆能M2固件编译

前言

上个月80块钱买了个1G运行内存的ZN-M2，对别人的固件不太放心，于是想自己编译openwrt固件，顺带编译了一下ZTE E8820S固件，用的openwrt版本是最新的openwrt-23.05，特此记录

编译ZN-M2固件

ZN-M2是一个高通IPQ6000方案，高通是不开源的，只有神秘社区恩山论坛上流传的IPQ6000github仓库

这里我用的仓库也是fork别人的

我的github zn-m2源码仓库

根据官方的步骤，要编译就要经过以下步骤

git clone 源码仓库
安装依赖
scripts/feeds update -a
scripts/feeds install -a
make menuconfig
make download -j4 && make -j$(nproc) V=sc

这里用了别人的源码仓，也不需要修改什么，只需要根据自己的需求修改config即可，我这里不需要wifi，则关闭所有wifi相关的选项

这里关闭了wifi以后编译有些地方会报错，所以要关就关全，我经过了一星期的试错才修改出完整编译不会报错的.config

最终我的.config文件是这样的

步骤没问题就直接make就行了，毕竟坑我都帮你们踩过了

编译ZTE 8820s

注意，以下所指的官方库是openwrt/openwrt

这个路由器是我一年前花50多买的，方案是经典的mt7621，其实也没什么好说的，但由于我编译的固件是最新版本的，有些依赖会有奇怪的问题

先拿到openwrt源码

git clone https://github.com/openwrt/openwrt -b openwrt-23.05

首先官方的库是不支持E8820s的，这里要在target/linux/ramips/image/mt7621.mk添加相应的支持添加下面的一段

define Device/zte_e8820s
  $(Device/uimage-lzma-loader)
  $(Device/dsa-migration)
  BLOCKSIZE := 128k
  PAGESIZE := 2048
  KERNEL_SIZE := 4096k
  UBINIZE_OPTS := -E 5
  IMAGE_SIZE := 129280k
  IMAGES += factory.bin
  IMAGE/sysupgrade.bin := sysupgrade-tar | append-metadata
  IMAGE/factory.bin := append-kernel | pad-to $$(KERNEL_SIZE) | append-ubi | \
	check-size
  DEVICE_VENDOR := ZTE
  DEVICE_MODEL := E8820S
  DEVICE_PACKAGES := kmod-mt7603 kmod-mt76x2 \
	kmod-usb3
endef
TARGET_DEVICES += zte_e8820s

然后还要添加target/linux/ramips/dts/mt7621_zte_e8820s.dts文件

注意，这一段nand只适用于breed B70内存分区，uboot请确定你适用版本的分区，否则不要刷

然后就make menuconfig按照正常流程编译即可

完整config请见github

虽然能开机，但是使用一段时间后5G路由器会重启! 不使用5G是没问题的，之前用别人的固件也会出现这样的情况。我决定换用源码 lede源码
