WL18xx 调试

一、jorjin官网找到模块资料

http://www.jorjin.com/product.php?id=78

二、参考WL18xx在SAMA5D2-Xplained上的移植

WL18xx First Time Getting Started Guide (SAMA5D2-Xplained)

http://processors.wiki.ti.com/index.php/WL18xx_First_Time_Getting_Started_Guide_(SAMA5D2-Xplained)

1）编译WL18xx驱动包参考如下手册

WL18xx System Build Scripts
http://processors.wiki.ti.com/index.php/WL18xx_System_Build_Scripts

2）编译WL18xx驱动包需要安装Ubuntu的支持库

WL18xx WiFi Build Process

3）编译WL18xx驱动包需要配置linux kernel的wifi支持

WL18xx Platform Integration Guide
http://processors.wiki.ti.com/index.php/WL18xx_Platform_Integration_Guide

4）都配置好了，编译会出错，用户层协议nl80211.c有个结构体成员用错了

将wl8-build/build-utilites/src/driver/net/wireless/nl80211.c文件第5615行函数

    hdr = nl80211hdr_put(msg, info->snd_portid, info->snd_seq, 0,
                 NL80211_CMD_GET_LOW_SIGNAL_MESH);

中info->snd_portid参数改成info->snd_pid

编译完成了需要打包文件系统目录

tar zcvf /fs_skeleton.tbz2 ./*

覆盖到板子根目录就可以调试了wifi基本功能了，当然创建wifi文件系统之前需要配置好内核sdio驱动
tar xf ./fs_skeleton.tbz2 -C /

 

三、添加SAMA5D3板的linux内核SDIO驱动

看一下wifi下接在mmc接口上，有使能引脚、中断引脚、四根数据线等等
