SSD202 驱动WIFI-ssw01b的STA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

3.2.3 加载外设WIFI芯片驱动

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 ]; thenecho try $trial times
fi
if [ $trial -gt $maxtrycnt ];thenecho wlan0 not foundexit -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STA模式

# ifconfig wlan0 up
# ifconfig wlan0

ctrl_interface 需要和工具wpa_cli 保持一致

# cat /appconfigs/wpa_supplicant.conf
ctrl_interface=/tmp/wifi/run/wpa_supplicant
update_config=1

后台运行wifi
如果wpa_supplicant.conf已经包含了network信息，则自动连接，如果没有仅进行初始化。可用通过后期wpa_cli 操作连接

# wpa_supplicant -D nl80211 -i wlan0 -c /appconfigs/wpa_supplicant.conf -B &
# Successfully initialized wpa_supplicant
[Sstar_log]:ieee80211_mgd_auth:(94:87:e0:47:64:db),ssid(chxm)
[Sstar_log]:Sstar_set_priv_queue_cap:[0],queue_cap[224]
[Sstar_log]:wlan0: authenticated
[Sstar_log]:ieee80211_start_connecting_work:bssid(94:87:e0:47:64:db)
[Sstar_log]:wlan0: associated
[Sstar_log]:[94:87:e0:47:64:db]:20M channel
[Sstar_log]:ieee80211_wk_connecting: time out
[Sstar_log]:ieee80211_ifa_changed(wlan0):IPv4 enable,end_time(307150)

关闭wifi功能

killall wpa_supplicant
killall udhcpc 可以不用，因为其它网口还需要

3.4 wpa_cli 操作剪辑

建立连接

# wpa_cli -i wlan0 scan
OK
# wpa_cli -i wlan0 scan_result
bssid / frequency / signal level / flags / ssid
94:87:e0:47:64:db   2447    -40 [WPA2-PSK-CCMP][ESS]    chxm
# wpa_cli -i wlan0 add_network
0
# wpa_cli -i wlan0 set_network 0 ssid '"chxm"'
OK
# wpa_cli -i wlan0 set_network 0 psk '"chxmtest123"'
OK

保存连接信息

# wpa_cli -i wlan0 save_config
OK

配置文件被修改

# cat /appconfigs/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
update_config=1network={ssid="chxm"psk="chxmtest123"
}

选择已有的连接

# wpa_cli -i wlan0 list_network
network id / ssid / bssid / flags
0   chxm    any [DISABLED]
# wpa_cli -i wlan0 select_network 0
OK
#

查看wifi状态

# wpa_cli -i wlan0 list_network
network id / ssid / bssid / flags
0   chxm    any [CURRENT]
# wpa_cli -i wlan0 status
bssid=94:87:e0:47:64:db
ssid=chxm

#

激活连接

# wpa_cli -i wlan0 enable_network 0
OK

断开连接

# wpa_cli -i wlan0 disable_network 0
[Sstar_log]:ieee80211_mgd_deauth
