SSD202 驱动WIFI-ssw01b的AP模式

1 电路相关

• 复位芯片方法1

echo ON > /dev/wifi_reset
echo OFF > /dev/wifi_reset

• 复位芯片方法2

echo 71 > /sys/class/gpio/export  
echo out > /sys/class/gpio/gpio71/direction
echo 0 > /sys/class/gpio/gpio71/value
sleep 2
echo 1 > /sys/class/gpio/gpio71/value

2 编译步骤

内核编译：

• Networking support ->Networking options ->802.1d Ethernet Bridging
• CONFIG_RFKILL=y
  文件系统：
• 工具需要：bridge-utils，wireless-tools, dhcpd

3 测试步骤

3.1 配置运行的动态库路径：

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:./:/config/lib/:/customer/lib/:/config/wifi/
export PATH=$PATH:/config/wifi/

3.2 加载驱动：

insmod /config/wifi/llc.ko
insmod /config/wifi/stp.ko
insmod /config/wifi/bridge.ko
/config/wifi/ssw01bInit.sh

3.2.1 初始化wifi芯片

• 芯片 BANK-0xe OFFSET-0x30 写入 0x11
• 芯片 BANK-0x103c OFFSET-0x8 写入 0x0
• 延时一段时间
• 芯片 BANK-0x103c OFFSET-0x8 写入 0x10

# /config/riu_w e 30 11
/config/riu_w 103c 8 00
sleep 0.01
/config/riu_w 103c 8 10BANK:0xE 16bit-offset 0x30
0x0011
# /config/riu_w 103c 8 00
BANK:0x103C 16bit-offset 0x08
0x0001
# sleep 0.01
# /config/riu_w 103c 8 10
BANK:0x103C 16bit-offset 0x08
0x0011
# 

3.2.2 建立必要的文件目录

touch /appconfigs/hosts
mkdir -p /var/run/wpa_supplicant
chmod 777 /var/run/wpa_supplicant
mkdir -p /var/run/hostapd		
chmod 777 /var/run/hostapd
mkdir -p /appconfigs/misc/wifi/ # 具体不知道干什么用
mkdir -p /var/wifi/misc/ # 保存 dnsmasq一些信息
mkdir -p /var/lib/misc/  # 一些wifi的日志和配置

3.2.4 检测对应外设节点

检查 wlan0 是否被建立节点

mdev -s
wlan0=`ifconfig -a | grep wlan0`
trial=0
maxtrycnt=50
while [ -z "$wlan0" ] && [ $trial -le $maxtrycnt ]
do 
    sleep 0.2
    #echo currect try $trial...
    trial=$(($trial + 1 ))
    wlan0=`ifconfig -a | grep wlan0`
done
if [ $trial -le $maxtrycnt ]; then
    echo try $trial times
fi
if [ $trial -gt $maxtrycnt ];then
    echo wlan0 not found
    exit -1
fi

3.2.5 操作日志开关

echo LOG_WARN=OFF > /sys/module/ssw101b_wifi_usb/Sstarfs/Sstar_printk_mask
echo LOG_INIT=OFF > /sys/module/ssw101b_wifi_usb/Sstarfs/Sstar_printk_mask
echo LOG_EXIT=OFF > /sys/module/ssw101b_wifi_usb/Sstarfs/Sstar_printk_mask
echo LOG_SCAN=OFF > /sys/module/ssw101b_wifi_usb/Sstarfs/Sstar_printk_mask
echo LOG_LMAC=OFF > /sys/module/ssw101b_wifi_usb/Sstarfs/Sstar_printk_mask
echo LOG_PM=OFF > /sys/module/ssw101b_wifi_usb/Sstarfs/Sstar_printk_mask

3.3 启动AP模式

# ifconfig wlan0 up
# ifconfig wlan0

• ctrl_interface 需要和工具hostapd_cli保持一致

# cat /config/wifi/hostapd.conf
interface=wlan0
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
driver=nl80211
ssid=ssw101bap
hw_mode=g
channel=4
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=3
wpa_passphrase=12345678
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP# 

• 启动wifi的ap模式

# hostapd -B /config/wifi/hostapd.conf
Configuration file: /config/wifi/hostapd.conf
[Sstar_log]:br0_netdev_open()-1116: dev_get_by_name(br0) failed2![Sstar_log]:br0_netdev_open()-1116: dev_get_by_name(br0) failed2!
Using interface wlan0 with hwaddr 24:14:07:16:65:61 and ssid "ssw101bap"

[Sstar_log]:Sstar_set_priv_queue_cap:[0],queue_cap[224]
wlan0: interface state UNINITIALIZED->ENABLED
wlan0: AP-ENABLED 
# 

• 配置wifi的设备IP

ifconfig wlan0 192.168.1.1

• 启动DHCP和DNS服务
  这里用的是dnsmasq 工具，有人会用udhcp

dnsmasq -i wlan0 --no-daemon -C /config/wifi/dnsmasq.conf & 

3.5 其他设备连接热点

• 连接
