 各位好，本人用的迅为i.MX6Q 开发板在ubuntu下的wifi 无法使用，于是参照了帖子：http://bbs.topeetboard.com/forum.php?mod=viewthread&tid=4165迅为4412全能版V_4.0 ubuntu 在Android4.4.4的内核下移植wifi[/url] 进行了移植, 但是无法成功启动wifi。

首先我重新编译了需要的内核模块驱动，并将模块放置在了 /lib/modules下

除去模块加载的启动脚本如下：

1. chmod 0777 /dev/stpwmt

2. #chmod 0666 /dev/stpgps

3. #chmod 0666 /dev/fm

4. chmod 0777 /dev/wmtWifi

5. chmod 0660 /dev/ttySAC0

6. #chmod 0666 /dev/gps

7. 

8. /system/bin/6620_launcher -m 1 -b 115200 -n /system/etc/firmware/mt6620_patch_hdr.bin -d /dev/ttySAC0 &

9. 

10. sleep 5

11. 

12.   echo 1 > /dev/wmtWifi

13. 

14.   wpa_supplicant -d -Dwext -iwlan0 -c /etc/wpa_supplicant.conf &

15.   sleep 3

16.   dhclient wlan0 &

17.

加载模块信息如下：
root@iMX6-ubuntu-desktop:~# lsmod
Module                  Size  Used by
wlan_mt6620           660442  0

mtk_hif_sdio           41707  2 wlan_mt6620,mtk_stp_wmt

1. 但是wifi 启动失败，内核日志如下：
