#修改WiFi/BT模组 本节以修改WiFi/BT模组为例，演示修改替换一个模块的方法。 在部分版本的的R329 Tina中（如全志官方对外release的v0.5版本R329 Tina），EVB5方案配置的Realtek 8723D无线模组。如果我们要替换成全志的XR829无线模组要怎么做呢？大概需要如下几步： ## 修改内核配置 首先，我们先获取环境变量，选好方案： ```bash source build/envsetup.sh lunch ``` 然后make kernel_menuconfig配置内核： ```bash make kernel_menuconfig ``` 进行无线模组配置选项： ```bash Device Drivers > Network device support > Wireless LAN ``` 可以看到当前选择的模组是Realtek 8723D  *<M>表示编译成模块，可以在启动的时候实用启动脚本加载，<\*>表示编译到内核。 我们将Realtek 8723D反选，并选上XR829：  ## 修改Tina配置 ```bash make menuconfig ``` ### Firmware 进入*Firmware*目录，反选r8723ds-firmware，并选上xr829-firmware和xr829 with 40M sdd。xr829 with 40M sdd意思是XR829采用40MHz的外挂晶振。 ```bash <*> xr829-firmware..................................... Xradio xr829 firmware [*] xr829 with 40M sdd ```  ### Wireless Driver 进入*Kernel modules > Wireless Driver*，反选*kmod-net-rtl8723ds*，并选上*kmod-net-xr829*和*kmod-net-xrbtlpm*，意思是启动的时候加载xr829模块。  ## 重新编译打包烧写固件 ```bash make -j32 pack ``` 烧写固件后，使用wifi扫描demo测试，就可以扫描到附近的wifi信号： ```bash root@TinaLinux:/# wifi_scan_results_test ********************************* ***Start scan!*** ********************************* bssid / frequency / signal level / flags / ssid 64:6e:97:5a:5a:e4 2462 -55 [WPA-EAP-CCMP+TKIP][WPA2-EAP-CCMP+TKIP][ESS] AWOffice 66:6e:97:1a:5a:e4 2462 -55 [WPA2-PSK-CCMP][ESS] AWTest 7e:b5:9b:2d:e1:63 2437 -56 [WPA-PSK-CCMP+TKIP][WPA2-PSK-CCMP+TKIP][ESS] AW-IT-Test 66:6e:97:1b:14:42 2462 -56 [WPA-PSK-CCMP+TKIP][WPA2-PSK-CCMP+TKIP][ESS] AWTest 7c:b5:9b:fd:e1:bd 2437 -58 [WPA-EAP-CCMP+TKIP][WPA2-EAP-CCMP+TKIP][ESS] AWOffice 7c:b5:9b:fd:e1:63 2437 -58 [WPA-EAP-CCMP+TKIP][WPA2-EAP-CCMP+TKIP][ESS] AWOffice 7e:b5:9b:1d:e1:63 2437 -58 [WPA2-PSK-CCMP][ESS] AWTest 7e:b5:9b:1d:e1:bd 2437 -61 [WPA2-PSK-CCMP][ESS] AWTest 88:d7:f6:88:8b:c0 2412 -37 [WPA2-PSK-CCMP][WPS][ESS] AW-PDC-PD4-316Test 90:67:1c:f8:11:ac 2437 -36 [WPA-PSK-CCMP+TKIP][WPA2-PSK-CCMP+TKIP][WPS][ESS] AW-PDC-RTOS-MUSIC 00:6b:8e:4e:c0:08 2412 -45 [WPA-PSK-CCMP][WPA2-PSK-CCMP][ESS] AW-PDC-PD4-315test c8:4c:75:40:86:ff 2452 -54 [WPA-EAP-CCMP+TKIP][WPA2-EAP-CCMP+TKIP-preauth][ESS] Allwinner c4:f0:81:63:9d:31 2437 -59 [WPA2-PSK-CCMP][ESS] \x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 f0:c9:d1:b3:15:49 2412 -55 [WPA-PSK-TKIP][WPA2-PSK-CCMP][ESS] AP-XRADIO 64:6e:97:5b:14:42 2462 -64 [WPA-EAP-CCMP+TKIP][WPA2-EAP-CCMP+TKIP][ESS] AWOffice bc:46:99:d6:62:7c 2462 -60 [WPA-PSK-CCMP][WPA2-PSK-CCMP][ESS] SochipR3 38:1c:1a:2e:b3:52 2437 -63 [WPA2-PSK-CCMP][ESS] AWTest ec:6c:9f:af:89:79 2447 -63 [WPA2-PSK-CCMP][ESS] AW-APD-GMSipv6 74:a5:28:9a:fc:d4 2432 -65 [WPA-PSK-CCMP+TKIP][WPA2-PSK-CCMP+TKIP][WPS][ESS] AW-PTD-HK 04:d4:c4:b9:b9:f8 2437 -65 [WPA2-PSK-CCMP][WPS][ESS] ipv6 ac:e3:42:9c:7f:79 2437 -68 [WPA2-PSK-CCMP][WPS][ESS] 00:1c:a3:14:6a:de 2422 -73 [WPA2-PSK-CCMP][ESS] AW-PD4-R818 8c:be:be:24:6f:ff 2422 -70 [WPA-PSK-CCMP+TKIP][WPA2-PSK-CCMP+TKIP][WPS][ESS] AW-PTD-TEST 7e:b5:9b:1d:e1:a3 2462 -75 [WPA2-PSK-CCMP][ESS] AWTest 80:e8:6f:d9:fd:a1 2412 -73 [WPA-EAP-CCMP][WPA2-EAP-CCMP][ESS] AWOffice 80:e8:6f:d9:fd:a2 2412 -73 [WPA2-PSK-CCMP][ESS] AWTest 80:8f:1d:8a:36:76 2452 -60 [WPA-PSK-CCMP][WPA2-PSK-CCMP][ESS] AW-PDC-PD2-TEST 38:1c:1a:2e:b3:51 2437 -63 [WPA-EAP-CCMP][WPA2-EAP-CCMP][ESS] AWOffice b8:55:10:94:90:b4 2427 -74 [WPA-PSK-CCMP][WPA2-PSK-CCMP][WPS][ESS] AW-ANC-TOTOLINK-N600RV2#34 80:e8:6f:d9:5d:62 2412 -75 [WPA2-PSK-CCMP][ESS] AWTest 80:e8:6f:d9:5d:61 2412 -76 [WPA-EAP-CCMP][WPA2-EAP-CCMP][ESS] AWOffice ****************************** Wifi get_scan_results: Success! ****************************** ``` 如果固件的模组不对应，使用wifi相关demo时会提示wifi打开失败： ```bash root@TinaLinux:/# wifi_scan_results_test connect wpa_supplicant failed,please check wifi driver! wifi on failed ``` ## 修改蓝牙配置 以上修改只是完成了模组wifi部分，bt部分这时候测试是会打开失败的： ```bash root@TinaLinux:/# bt_test root@TinaLinux:/# 58279.055755: [bt_manager_init:212]:enable default profile from bt config. 58279.055900: [bt_manager_enable:400]:bt manager version:Version:3.0.1.202012201630,builed time:Dec 29 2020-02:46:30 58279.055915: [bt_test_sta[144.123489] sunxi-bt soc@03000000:bt: block state already is 1 tus_cb:71]:bt is turnning on.
