This article mainly introduces the iTOP-4412 development board in Ubuntu how to use WIFI, the article introduces in great detail, has a certain reference value, interested friends must read it!

Elite wifi configuration

After the electric start-up on the hair board enters the Ubuntu system, use the command "vi" in the serial port of the hair board.

/ etc/init.d/itop-set ", as shown below:

Then open the itop-set file and put the contents:

# mknod / dev/stpwmt c 1900

# mknod / dev/stpgps c 1910

# mknod / dev/fm c 193 0

# mknod / dev/wmtWifi c 194 0

# insmod / system/lib/modules/mtk_hif_sdio.ko

# insmod / system/lib/modules/mtk_stp_wmt.ko

# insmod / system/lib/modules/mtk_stp_uart.ko

# insmod / system/lib/modules/mtk_stp_gps.ko

# insmod / system/lib/modules/mt6620_fm_drv.ko

# insmod / system/lib/modules/mtk_fm_priv.ko

# insmod / system/lib/modules/mtk_wmt_wifi.ko WIFI_major=194

# insmod / system/lib/modules/wlan.ko

# chmod 0666 / dev/stpwmt

# chmod 0666 / dev/stpgps

# chmod 0666 / dev/fm

# chmod 0666 / dev/wmtWifi

# chmod 0660 / dev/ttySAC0

# chmod 0666 / dev/gps

# / system/bin/6620_launcher-M1-b 921600-n/system/etc/firmware/mt6620_patch_hdr.bin-d / dev/ttySAC0 &

# sleep 1

# echo 1 > / dev/wmtWifi

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

# dhclientwlan0 &

Change it to the following (do not change anything else, as this file also includes the wifi configuration of the full-featured board):

Mknod / dev/stpwmtc 190 0

Mknod / dev/stpgpsc 191 0

Mknod / dev/fm c 193 0

Mknod / dev/wmtWifi c 1940

Insmod / system/lib/modules/mtk_hif_sdio.ko

Insmod / system/lib/modules/mtk_stp_wmt.ko

Insmod / system/lib/modules/mtk_stp_uart.ko

Insmod / system/lib/modules/mtk_stp_gps.ko

Insmod / system/lib/modules/mt6620_fm_drv.ko

Insmod / system/lib/modules/mtk_fm_priv.ko

Insmod / system/lib/modules/mtk_wmt_wifi.ko WIFI_major=194

Insmod / system/lib/modules/wlan.ko

Chmod 0666 / dev/stpwmt

Chmod 0666 / dev/stpgps

Chmod 0666 / dev/fm

Chmod 0666 / dev/wmtWifi

Chmod 0660 / dev/ttySAC0

Chmod 0666 / dev/gps

/ system/bin/6620_launcher-m1-b921600-n / system/etc/firmware/mt6620_patch_hdr.bin-d / dev/ttySAC0 &

Sleep 1

Echo 1 > / dev/wmtWifi

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

Dhclient wlan0 &

Save and exit after the modification is complete, and then use the command "vi / etc/wpa_supplicant.conf", as shown below:

# sleep 1

Change it to the following (do not change anything else, because this file also includes the wifi configuration of the elite board):

Insmod / lib/firmware/ath7k/AR6003/hw2.1.1/cfg80211.ko
