《电务工作日志》Android版,工作日志（wifi之dhd debug 2）

进入系统之后出现了这样的问题：

init: cannot find '/system/bin/wlan_tool', disabling

'wpa_supplicant'

init: no such service ':unload'

暂时估计是init.rc上面有错误。

1、

# create basic filesystem structure

#

zhoutj.add.20110916

mkdir

/data/system/wpa_supplicant 0770 wifi wifi

#add.end

2、

#zhoutj.add.20110916

service wpa_supplicant /system/bin/logwrapper

/system/bin/wpa_supplicant /

-Dwext -iwlan0 -c /data/misc/wifi/wpa_supplicant.conf

disabled

oneshot

#add.end

3、

#zhoutj.add.20110916

service dhcpcd /system/bin/logwrapper /system/bin/dhcpcd -BK -f

/system/etc/dhcpcd/dhcpcd-wlan0.conf wlan0

disabled

oneshot

#add.end

然后通过User_Guide：

# dd if=uramdisk.img

of=ramdisk.img.gz skip=64 bs=1

# gunzip ramdisk.img.gz

# mkdir ramdisk; cd ramdisk

# cpio -i <

../ramdisk.img

# vim init.rc (modify the init.rc, change the

mmcblk0 to mmcblk1)

# find . | cpio --create --format='newc' |

gzip > ../ramdisk.img

# mkimage

-A arm -O

linux -T ramdisk -C none -a 0x70308000 -n "Android Root Filesystem"

-d ./ramdisk.img ./uramdisk.img

将init.rc添加到uramdisk.img中。

然而串口打印的信息为:

/data/misc/wifi/wpa_supplicant/wlan0 is not ready, cnt=-1

E/WifiHW ( 2008): wifi_connect_to_supplicant:

到了这里估计要修改三个地方：

1.wifi.c

2.BroadConfig.mk

3.init.rc
