极贰openwrt 编译 7620a+7621e，能够开启 2.4G，5G 该怎么打开

Posted 2023-04-19

参考技术A 1. 下载openwrt最新代码
2. 下载openwrt官方的7621e驱动https://github.com/openwrt/mtk-wifi-gpl
3. 参考https://code.google.com/p/openwrt-hiwifi/, 打上hc5761的补丁，使用其hc5761的config，并开启mtk-wifi-gpl
4. 编译完成通过ttl，sysupgrade -F -n openwrt-ramips-mt7620a-hiwifi-hc5761-squashfs-sysupgrade.bin刷机
5. 完成重启，2.4G能够开启

openwrt 配置openwrt及编译

导航

1. 配置openwrt

2. 编译openwrt

 

1. 配置openwrt

　　在openwrt的根目录下，执行make menuconfig.

这个界面我也只是了解了这两个选项而已，其他的留作以后补充。主芯片就是你的路由器用的是什么芯片，具体的板子是指匹配了这个板子后，一些驱动，IO口对的上。

找不到的，不一样的，我暂时也不清楚怎么办，百度过这个驱动很难写，至于我为什么知道是这个型号，因为是公司前辈告诉我的。不然我也是无从得知。

 

暂时先这样吧，等有时间了，再回来补充这一块的知识。

save之后就可以exit。

配置完成。

 

2. 编译openwrt

　　2.1 clean，以防未知错误。make clean

　　2.2 编译 make V=s 来编译。第一遍最好不要用多核编译 ，如果使用多核编译的话就加j=n n是你的cpu核数。

　　注：第一次编译要联网，因为会下载很多东西。下载在dl文件夹下。

编译很久，要慢慢等待。在编译完成之后，会生成一个bin目录。

在这个路径下，就会生成编译好的bin文件。

至此，编译结束。
