[R3 nand] USB wifi RTL8188EUS 驱动移植<暂时不以package的方式加入>

1.修改设备树  /board/widora/mangopi/r3/devicetree/linux/devicetree.dts

&usb_otg {
        dr_mode = "host"; /* host peripheral */
        status = "okay";
};

2.下载驱动源码https://codeload.github.com/aircrack-ng/rtl8188eus/zip/v5.3.9
解压后拷贝到 /output/build/linux-5.4.66/drivers/net/wireless/realtek/rtl8188eus
2.1修改/output/build/linux-5.4.66/drivers/net/wireless/realte/Kconfig,加入

source "drivers/net/wireless/realtek/rtl8188eus/Kconfig"

2.2修改/output/build/linux-5.4.66/drivers/net/wireless/realte/Makefile,加入

obj-$(CONFIG_RTL8188EU)         += rtl8188eus/

2.3修改 rtl8188eus/include/osdep_service_bsd.h,第120行改为

#define LINUX_VERSION_CODE KERNEL_VERSION(5, 4, 66)

3.加入wpa_supplicant工具

make menuconfig
localtion
	->Target pckages
		->Networking applications
			[*] wpa_supplicant

4.make linux-menuconfig 配置网络

localtion
	 -*-   Wireless  --->
		<*>   cfg80211 - wireless configuration API
		[*]   support CRDA     
		[*]   cfg80211 wireless extensions compatibility 
		<*>   Generic IEEE 802.11 Networking Stack (mac80211)
        [*]   Minstrel
	[*] Networking support  ---> 
		 <*>   RF switch subsystem support  ---> 
	->Device Drivers
		[*]   Network device support  ---> 
			[*]   Network core driver support
			<*>   IEEE 802.1AE MAC-level encryption (MACsec)
  			 [*]  Wireless LAN  ---> 
				[*]   mac80211-based legacy WDS support
				[*]   Ralink devices 
				<*>   Ralink driver support  --->
					[*]   Realtek devices
					<M>   Realtek 8188E USB WiFi
					
		[*] USB support  --->
			<*>   Support for Host-side USB	 
			*** USB Host Controller Drivers *** 
			<*>   EHCI HCD (USB 2.0) support
			<*>   Generic EHCI driver for a platform device 
			<*>   OHCI HCD (USB 1.1) support
			<*>   Generic OHCI driver for a platform device
			       MUSB Mode Selection (Host only mode)  ---> #别错过这里,否则USB模式可能会出错
			<*>   Inventra Highspeed Dual Role Controller
			<*>   ChipIdea Highspeed Dual Role Controller
			[*]   ChipIdea host controller
			

5.编译,刷机。

6.安装驱动,启动网卡,创建运行需要的临时文件夹

	insmod ./lib/modules/5.4.66/kernel/drivers/net/wireless/realtek/rtl8188eus/8188eu.ko
	ifconfig wlan0 up
	mkdir -p /var/run/wpa_supplicant

7.新建配置文件 /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
network={
	ssid="mishare"  #wifi名字
	psk="qwer1234" #wifi密码
}

8.链接网络

	wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

9.配置IP地址<暂时没有使用udhcpc工具>

ifconfig wlan0 192.168.137.202
