內核dts配置

文件系統配置和更改

刪掉中間文件： buildroot/output/rockchip_rv1126_rv1109_xxx/target/etc/init.d/S45connman buildroot/output/rockchip_rv1126_rv1109_xxx/target/usr/bin/connmanctl buildroot/output/rockchip_rv1126_rv1109_xxx/target/usr/sbin/connmand app/netserver/main.c main函數直接return不執行buildroot/output/rockchip_rv1126_rv1109/target/etc/init.d/S36load_rv1109_wifi_modules //注釋掉下面這兩行 printf "load wifi modules: " #insmod /system/lib/modules/"8188fu.ko" #[ $? = 0 ] && echo "OK" || echo "FAIL" #注etc/init.d/目錄的文件在系統啟動時會依次被調用，所以WiFi的驅動會被自動加載，這里我們注釋掉它使用自己的wifi驅動根目錄external/下添加softapDemo.tgz.gz main.c下 +++ main.c/static char softap_name[64] = "wlan0"; +++ main.c/wlan_accesspoint_start(apName, apPassword); --- main.c/eth_accesspoint_start(); --- main.c/iftables_usb0_to_eth0(wan,lan); package/rockchip/Config.in 添加：source "package/rockchip/softap/Config.in"根目錄 make menuconfig BR2_PACKAGE_RKWIFIBT_RTL8188FU =y # 選擇對應的WiFi型號 其實也可不選我們不用原廠wifi驅動 BR2_PACKAGE_IPC_DAEMON = n BR2_PACKAGE_NETSERVER = n BR2_PACKAGE_CONNMAN = n BR2_PACKAGE_DHCPCD = y BR2_PACKAGE_SOFTAP=y make savedefconfig make netserver-dirclean make connman-dirclean make ipc-daemon-dirclean make softap-dirclean make rkwifibt-dirclean #清除掉之前的 ./build.sh rootfs #編譯文件系統 注意： 編譯好看看buildroot/output/rockchip_rv1126_rv1109/target/etc/init.d/S36load_rv1109_wifi_modules 有沒被覆蓋，覆蓋掉的話需要重新注釋

驅動編譯

修改配置
SDK\extern\rtl8188FU_linux_v5.11.5-13-g2482755ff.20210615\Makefile

CROSS_COMPILE := arm-linux-gnueabihf- KSRC := rockchip_new_20220628/kernel RTL模組： 使用p2p0作為softap功能，通過內核驅動的配置生成p2p0，如果沒有p2p0節點請檢查這里的配 置 EXTRA_CFLAGS += -DCONFIG_PLATFORM_ANDROID CONFIG_PLATFORM_ARM_RK2818 = y CONFIG_AP_MODE = y CONFIG_POWER_SAVING = n CONFIG_MP_INCLUDED = y

make clean && make;

wifi工具編譯

libnl庫編譯

mkdir __install; ./configure CC=arm-linux-gnueabihf-gcc AR=arm-linux-gnueabihf-ar --prefix=$(pwd)/__install --host=arm-linux-gnueabihf; make && make install;

openssl編譯

mkdir __install; ./config no-asm no-shared --cross-compile-prefix=arm-linux-gnueabihf- --prefix=$(pwd)/__install 去掉CFLAG參數中的 -m64 ，SHARED_LDFLAGS參數中的 -m64 make && make install

wpa_supplicant編譯

cd SDK/extern/wifi_tool/wpa_supplicant_8_kk_4.4_rtw_r25669.20171213/wpa_supplicant; cp defconfig .config; #Makfefile中添加libnl和禮包ssl的路徑 CC=arm-linux-gnueabihf-gcc CFLAGS += -I../../libnl-1.1.4/__install/include CFLAGS += -I../../openssl-1.0.2g/__install/include LIBS += -L../../libnl-1.1.4/__install/lib -lnl -lm -lpthread LIBS += -L../../openssl-1.0.2g/__install/lib -lssl -lcrypto -ldl #編譯 make clean && make; #生成wpa_supplicant和wpa_cli arm-linux-gnueabihf-strip wpa_cli arm-linux-gnueabihf-strip wpa_supplicant

hostapd編譯(不過我沒用到，調不通，用的是rk自帶的)

cd SDK/extern/wifi_tool/wpa_supplicant_8_kk_4.4_rtw_r25669.20171213/hostapd; cp defconfig .config; #Makfefile中添加libnl和禮包ssl的路徑 CC=arm-linux-gnueabihf-gcc CFLAGS += -I../../libnl-1.1.4/__install/include CFLAGS += -I../../openssl-1.0.2g/__install/include LIBS += -L../../libnl-1.1.4/__install/lib -lnl -pthread LIBS += -L../../openssl-1.0.2g/__install/lib -lssl -lcrypto -ldl #編譯 make clean &&& make;

開機運行腳本測試WIFI—STA模式

開機后可以用lsusb命令看看是否有wifi節點(ID為下圖：即為wifi模塊)

運行腳本
./wifi_test.sh

cd /mnt/wifi_lib echo host > /sys/devices/platform/ff4c0000.usb2-phy/otg_mode #使能usb為Host模式，這個建議放到/etc/ini.d/rcS里面開機執行一次就好 killall softapDemo&&killall hostapd && killall udhcpd rmmod wlan sleep 1 insmod wlan.ko #加載后可以用iwlist wlan0 scan命令驗證一下能不能搜索到熱點 export LD_LIBRARY_PATH=/mnt/wifi_lib/nl_lib:$LD_LIBRARY_PATH export LD_LIBRARY_PATH=/mnt/wifi_lib/lib:$LD_LIBRARY_PATH ifconfig wlan0 up ./wpa_supplicant -B -iwlan0 -c wpa_supplicant.conf -Dnl80211 ./wpa_cli -i wlan0 status route del default;route del 255.255.255.255 udhcpc -iwlan0 -q& route add -net 255.255.255.255 netmask 255.255.255.255 dev wlan0

然后板子就可以通過wifi ping外網了

運行腳本測試WIFI-AP模式

./hostapd.sh

killall wpa_supplicant sleep 2 ifconfig wlan0 0.0.0.0 ifconfig wlan0 down killall hostapd && killall udhcpd softapDemo

然后可以用筆記本嘗試連接熱點ping板子wlan0 ip是否能通
