按照模块厂家提供的资料添加相关驱动以及配置不再赘述，主要是调试过程中系统层面有一个问题，首先看log：D use-Rlog/RLOG-RIL RILU: find quectel module /sys/bus/u***/devices/8-1 idVendor=2c7c idProduct=0800D SubscriptionController: [getPhoneId]- no sims, returning default phoneId=0D use-Rlog/RLOG-RIL RILU: find /sys/bus/u***/devices/8-1:1.2/ttyUSB2D use-Rlog/RLOG-RIL RILU: ttyAT = ttyUSB2D use-Rlog/RLOG-RIL RILU: find /sys/bus/u***/devices/8-1:1.3/ttyUSB3D use-Rlog/RLOG-RIL RILU: ttyPPP = ttyUSB3D use-Rlog/RLOG-RIL RILU: find /sys/bus/u***/devices/8-1:1.0/ttyUSB0D use-Rlog/RLOG-RIL RILU: ttyDM = ttyUSB0D use-Rlog/RLOG-RIL RILU: find /sys/bus/u***/devices/8-1:1.1/ttyUSB1D use-Rlog/RLOG-RIL RILU: ttyGPS = ttyUSB1D use-Rlog/RLOG-RIL RILU: find /sys/bus/u***/devices/8-1:1.4/net/wwan0D use-Rlog/RLOG-RIL RILU: u***net_adapter = wwan0D use-Rlog/RLOG-RIL RILU: find /sys/bus/u***/devices/8-1:1.4/u***misc/cdc-wdm0D use-Rlog/RLOG-RIL RILU: qmichannel = cdc-wdm0E use-Rlog/RLOG-RIL RILU: Cannot access file:/dev/cdc-wdm0, errno = 2(No such file or directory)E use-Rlog/RLOG-RIL RILU: patch for 'system/core/init/devices.cpp' is required!......D use-Rlog/RLOG-RIL MBIM: fail to open (/dev/cdc-wdm0), errno: 2 (No such file or directory)D use-Rlog/RLOG-RIL SETUP_DATA_CA: ql_set_data_call_info pdp=1, ifname=wwan0, iptype=4, ipaddr=(null)D use-Rlog/RLOG-RIL SETUP_DATA_CA: wwan0 IP Address: 0.0.0.0/0D use-Rlog/RLOG-RIL SETUP_DATA_CA: get_local_ip: 0.0.0.0/0, cost 0 secE use-Rlog/RLOG-RIL SETUP_DATA_CA: Unable to setup PDP in requestSetupDataCall很明显，找不到/dev/cdc-wdm0，确实没有注册，原因就在devices.cpp中注册/dev/cdc-wdm0的逻辑了，系统将cdc-wdm0注册成了u***misc设备，而该文件中缺少处理u***misc的逻辑，只需要稍作修改即可：--- a/system/core/init/devices.cpp+++ b/system/core/init/devices.cpp@@ -679,7 +679,7 @@ static void handle_generic_device_event(struct uevent *uevent) return;mkdir_recursive_for_devpath(devpath);} else if (!strncmp(uevent->subsystem, "u***", 3)) {-if (!strcmp(uevent->subsystem, "u***")) {+if (!strcmp(uevent->subsystem, "u***")||!strcmp(uevent->subsystem, "u***misc")) { if (uevent->device_name) {if (!assemble_devpath(devpath, "/dev", uevent->device_name))return;这样模块即可正常拨号上网。原作者：空~。
