全志平台Tina系统8723ds wifi天线调试

在有的方案中wifi部分由模组贴片换成了chip on board(COB)，由于使用的天线由s1切换到了s0，因此，在使用WIFI和BT前，需要进行efuse设置。

设置前需确保固件编译了rtwpriv这程序，如果没有选可以在make menuconfig里选上。

进行设置前需要先打开wifi：ifconfig wlan0 up

把天线的map设置为11：

root@TinaLinux:/# rtwpriv wlan0 efuse_set wmap,c3,11

wlan0 efuse_set:WiFi write map compare OK

rtwpriv wlan0 efuse_get realmap

看一下此时的map，会发现0xc30 的3写成了11：

重启生效。

扫描一下wifi看附件wifi的信号：

root@TinaLinux:/# wifi_scan_results_test

ctrl_interface != /etc/wifi/sockets

WiFi on success!

It has no wifi auto connect when wifi on!

c3设置成10：

看一下此时的map:

如果有时候默认设置c3是51，就会由于天线没设置对导致信号较差：
