整理记录一些 DW33D 刷 Openwrt 的 Nand 固件教程，主要内容来源于恩山论坛，加上一些文字歧义的修正与实践记录。
背景知识
dw33d内部有几个存储空间（可理解为硬盘），SPI-NOR(16M)、 NAND(128M)、 TF卡（16G）。
原厂固件是在NOR上的，一些旧版（lede 17.x）也是设计刷到NOR上，这类固件称为(ath1x)。BREED默认也是刷到NOR，启动也是NOR。
后来openwrt把dw33d纳入官方支持时候，改成使用NAND作为固件区域，这类称为（ath79），或者nand固件。
旧版固件虽然刷入简单（可以Breed WEB页面直刷），但是可用空间非常有限。
nand固件的刷入较为复杂，但是有足够大的存储空间（可用空间70M+），可以安装很多可选插件。
Breed虽然在dw33d上工作不完美，但是还是比u-boot简化一丢丢。
刷机方法可以是u-boot，连接TTL线操作；也可以不拆外壳，telnet操作；

简介解释
Breed刷Nand看起来很复杂，其实总共3个步骤：
Breed设置环境变量
PC开启http服务器
Breed Telnet下载并写入固件。
1.Breed设置环境变量
无论你是通过什么方法刷的Breed，现在需要开机长按 reset 进入breed
然后通过 putty 或者系统任意支持 telnet 客户端的方式连接到路由器上
telnet 192.168.1.1在 telnet 中：执行修改环境变量配置的起始地址和大小
envconf 0x6000000 0x20000你也可以在web，这个页面看到当前的配置
http://192.168.1.1/envconf.html
修改完毕后，记得重启
reset2.开启HTTP服务器
教程里推荐使用的是 MyWebServer
在此你可以使用任意方式将本地电脑开启一个HTTP服务器，并将文件丢到网站根目录。
我这里使用的是PHP开启的 web 服务器：
php -S 0.0.0.0:9991确保路由器可以通过 wget 连接到你的电脑，你可以在虚拟机或者现有正常的路由器进行测试。
wget http://你的电脑IP:端口/openwrt-ath79-nand-domywifi_dw33d-squashfs-factory.bin无论使用哪一种方式，你需要确保路由器能够成功连接到你，并且能够下载到文件，切记关闭防火墙。
备注：这里 wget 无关文件名，所以后面刷写也没有引用文件，猜测是 telnet 里的 wget 会直接将文件写入对应分区，不存在文件系统也不用指定。
3.配置环境变量并刷写固件
按照教程配置环境变量
env set network.ipaddr 192.168.1.1
env set network.netmask 255.255.255.0
env set autoboot.disabled 0
env set autoboot.delay 5
env set autoboot.command "boot flash bank 0 0x0"
env save通过 wget 下载固件，并刷写固件。
重点是注意flash命令的最后一个参数，应该跟下载时候的长度匹配（或更大）。
这里是最后两个 flash 命令中的 0xd00000 都要改成对应的固件大小。
wget http://192.168.0.254/firmware/dw33d-factory.bin
##### 注意显示的长度，0xd00000应该跟后续两个命令中对应位置的参数相同
#####-> Length: 13631488/0xd00000 (13MB) [application/octet-stream]
flash bank 0 erase 0x0 0xd00000
flash bank 0 write 0x0 0x80000000 0xd00000举例说明：
breed> wget http://192.168.1.17:9991/openwrt-ath79-nand-domywifi_dw33d-squashfs-factory.bin
wget http://192.168.1.17:9991/openwrt-ath79-nand-domywifi_dw33d-squashfs-factory.bin

Length: 31326208/0x1de0000 (29MB) [application/octet-stream]
Saving to address 0x80000000
[========================================================================] 100%
Transmission completed in 5.5s.根据这个 wget 的结果来看，固件大小为：0x1de0000，修改也需要将两处均修改掉：
flash bank 0 erase 0x0 0x1de0000
flash bank 0 write 0x0 0x80000000 0x1de0000刷写成功后，重启耐心等待即可，注意将网卡 IP 设置为自动获取。
reset之后你就可以根据 openwrt web 中的升级固件功能，刷一些 squashfs-sysupgrade 类的固件。
错误解决
如果你遇到下面的错误，就是因为修改完环境变量配置没有重启导致的环境变量只读。
