The driving rtl8188eu of the whole Zhi A20 series

This tutorial is suitable for the development Board of the A20 system class.

My A20 board is using the Rtl8188eu Usb-wifi, it took three days to drive successfully, successfully connected to the router with WiFi, and ping through www.baidu.com.

Note:

Operating system: Linux-sunxi (not Android)

1. See if the 8188eu driver is supported in the kernel

Open Linux-sunxi/arch/arm/configs/sun7i_defconfig File

See if: Config_rtl8188eu=m does not have to be modified to Y

2. Complete the first step, as usual, burn the system to the SD card

3. Modify Script.bin

Delete [Wifi_para] This item

Add the following statement

[Usb_wifi_para]
usb_wifi_used = 1
Usb_wifi_usbc_num = 2

And then at the same time enable USBC2

My configuration is as follows:

[Usb_wifi_para]
usb_wifi_used = 1
Usb_wifi_usbc_num = 2

[USBC2]
usb_used = 1
Usb_port_type = 1
Usb_detect_type = 0
Usb_id_gpio =
Usb_det_vbus_gpio =
Usb_drv_vbus_gpio = port:ph22<1><0><default><0>
Usb_host_init_state = 1

4. Restart the Development Board

Check the/lib/modules/' uname-r '/kernel/drivers/net/wireless folder to see if there is a 8188eu.ko this driver, if there is a continuation.

In the terminal, enter:

1. Depmod-a
2. Modprobe 8188eu

Input IFCONFIG-A Now you should see Wlan0.

Modify/etc/network/interfaces

Auto Wlan0

Iface Wlan0 inet DHCP

Wpa-ssid "Router Account"

WPA-PSK "Router Password"

Save quit restart

Perform ping www.baidu.com ok!
