3 第三部分 顯示功能測試
3.1 操作說明 每項顯示功能測試都需要重啟系統進入到u-boot命令行，并在u-boot命令行下執行指令。
3.2 單屏顯示LVDS1 顯示
說明：默認為 LVDS1 顯示，即上電后不干預啟動的情況下，LVDS1 為顯示設備。
顯式配置 LVDS1 為顯示的方法： run load_scr; source; setenv display $disp_fb0_lvds1; saveenv; boot LVDS0 顯示 run load_scr; source; setenv display $disp_fb0_lvds0; saveenv; boot HDMI 顯示 run load_scr; source; setenv display $disp_fb0_hdmi; saveenv; boot LCD(RGB) 顯示 run load_scr; source; setenv display $disp_fb0_lcd; saveenv; boot
3.3 雙LVDS屏顯示LVDS1 + LVDS0 雙屏同步顯示 run load_scr; source; setenv display $disp_lvds_dul; saveenv; boot LVDS1 + LVDS0(fb4) 雙屏異步顯示 run load_scr; source; setenv display $disp_lvds_sep; saveenv; boot
3.4 雙屏異步顯示LVDS1 + HDMI 雙屏異步顯示 run load_scr; source; setenv display $disp_fb0_lvds1 $disp_fb1_hdmi; saveenv; boot LVDS1 + LCD(RGB) 雙屏異步顯示 run load_scr; source; setenv display $disp_fb0_lvds1 $disp_fb1_lcd; saveenv; boot LVDS0 + HDMI 雙屏異步顯示 run load_scr; source; setenv display $disp_fb0_lvds0$disp_fb1_hdmi; saveenv; boot LVDS0 + LCD(RGB) 雙屏異步顯示 run load_scr; source; setenv display $disp_fb0_lvds0 $disp_fb1_lcd; saveenv; boot HDMI + LVDS1 雙屏異步顯示 run load_scr; source; setenv display $disp_fb0_hdmi $disp_fb1_lvds1; saveenv; boot HDMI + LVDS0 雙屏異步顯示 run load_scr; source; setenv display $disp_fb0_hdmi $disp_fb1_lvds0; saveenv; boot LCD(RGB) + LVDS1 雙屏異步顯示 run load_scr; source; setenv display $disp_fb0_lcd $disp_fb1_lvds1; saveenv; boot LCD(RGB) + LVDS0 雙屏異步顯示 run load_scr; source; setenv display $disp_fb0_lcd $disp_fb1_lvds0; saveenv; boot
4 第四部分 擴展模塊功能演示
4.1 RTL8188 模塊功能演示（WIFI Client） 【測試說明】：使用RTL8188作為無線網卡連接到WIFI AP。
【接口標識】：WIFI、WIFI_ANT
【系統設備】：wlan0
測試操作
1. 確定“WIFI”標識處有貼上WIFI模塊，否則無需進行測試。
2. 把WIFI天線連接到“WIFI_ANT”標識的接口上。
3. 生成 SSID 的 WPA PSK 文件
命令格式: wpa_passphrase <ssid> [passphrase] =====> 輸入指令: wpa_passphrase MY-TEST-AP myzr2012 > /etc/wpa_supplicant.conf pkill wpa_supplicant 4. 連接 =====> 輸入指令: wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf
=====> 輸出信息： Successfully initialized wpa_supplicant rfkill: Cannot open RFKILL control device ==> rtl8188e_iol_efuse_patch IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready ...... 5. 獲取 IP =====> 輸入指令: udhcpc -i wlan0
=====> 輸出信息： udhcpc (v1.23.1) started Sending discover... Sending select for 192.168.43.121... Lease of 192.168.43.121 obtained, lease time 3600 /etc/udhcpc.d/50default: Adding DNS 192.168.43.1 6. 測試連接 =====> 輸入指令: ping -I wlan0 192.168.43.1 -c 2 -w 4
=====> 輸出信息： PING 192.168.43.1 (192.168.43.1) from 192.168.43.130 wlan0: 56(84) bytes of data. 64 bytes from 192.168.43.1: icmp_seq=1 ttl=64 time=5.66 ms 64 bytes from 192.168.43.1: icmp_seq=2 ttl=64 time=9.22 ms
--- 192.168.43.1 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1000ms rtt min/avg/max/mdev = 5.663/7.444/9.226/1.783 ms 測試結果
“0% packet loss”表示WIFI連接正常。
4.2 RTL8188 模塊功能演示（WIFI AP mode） 【測試說明】：使用RTL8188作為WIFI AP，并把手機連接到此AP。
【接口標識】：WIFI、WIFI_ANT
【系統設備】：wlan0
測試操作
1. 確定“WIFI”標識處有貼上WIFI模塊，否則無需進行測試。
2. 把WIFI天線連接到“WIFI_ANT”標識的接口上。
3. 為 wlan0 配置 IP： =====> 輸入指令: ifconfig wlan0 192.168.99.1
=====> 輸出信息： ==> rtl8188e_iol_efuse_patch IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready 4. 為 wlan0 啟用 DHCP 服務： =====> 輸入指令: touch /var/lib/misc/udhcpd.leases udhcpd -f /etc/my_udhcpd.conf &
=====> 輸出信息： [1] 469 udhcpd (v1.23.1) started 5. 為 wlan0 啟用 Host-AP 功能 =====> 輸入指令: hostapd /etc/my_hostapd.conf -B
