rf调试

①：先设置nv项

nv00453：Factory Testmode Phone Mode,设置为1，开机会先进入FTM模式，不至于在没配置好的情况下直接进入offline

nv06828：LTE BC Config ：选定lte支持的band的位

nv01878：RF Hardware Configuration,配置为你选定的rf_hw_type       （参照：modem_proc\rfc_jolokia\api\Rfc_hwid.h）

②：配置modem可以单独重启

#sudo push busybox  /data/

#adb shell

#  ./data/busybox find ./ -name restart_level

./sys/devices/soc.0/4080000.qcom,mss/subsys2/restart_level
./sys/devices/soc.0/a21b000.qcom,pronto/subsys1/restart_level
./sys/devices/soc.0/1de0000.qcom,venus/subsys0/restart_level

#cat ./sys/devices/soc.0/4080000.qcom,mss/subsys2/restart_level

SYSTEM

echo RELATED ./sys/devices/soc.0/4080000.qcom,mss/subsys2/restart_level   //modem 可以单独重启

③：QXDM抓去log

alt+i 清楚log

send_data 75 37 03 00   //重启modem

筛选log：rffe 或 rf，一下为筛选结果

从中可以判定哪个器件没检测到，如果    rfc_prd_id ，hw_prd_id=0x0不一样，则次器件出问题（图中第三个就有问题）

QXDM的其他命令：

mode online

mode mpl

send_data 75 37 03 00

.....

关于gpio的配置

    { (int)RFC_WTR4905_OM_RF_PATH_SEL_04,   { RFC_HIGH, -10 }, {RFC_LOW, 0 }  },

配置完成后，硬件测试管脚电平没有变高？？？最终确定是复用了

在modem_proc\rfc_jolokia\target\msm8909\src\Rfc_msm_signal_info_ag.c的rfc_msm8909_signal_info[]中74管脚用两个功能

解决办法：

自己使用的gpio是在modem_proc\rfc_jolokia\rf_card\rfc_wtr4905_om\common\src\Rfc_wtr4905_om_cmn_ag.cpp的rfc_wtr4905_om_sig_info[]中定义的，在这个数组中一个管脚不应该有服用，删掉不用的那个即可解决问题
