OpenWrt从零开发

工作笔记
有 N 人看过

这篇文章主要记录基于GitHub的OpenWRT19.02源码如何一步步配置，编译，得到适用于OK1046-C2的镜像。

在源码下执行make menuconfig之后的首选配置

首先是平台相关的必要配置：

Target System (NXP Layerscape)
Subtarget (ARMv8 64-bit based boards) 
Target Profile (NXP LS1046A-RDB Default)

然后是启用LUCI web图形界面

-> LuCI
    -> 1. Collections
        <*> luci................... LuCI interface with Uhttpd as Webserver (default)

内核模块打开ath10k和iwlwifi驱动的支持，其他的依赖项会自动选择
