本文主要是介绍3568 4G EC25调试，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1. 

//DTS配置
kernel\arch\arm64\boot\dts\rockchip\rk3568-evb1-ddr4-v10.dtsi
+    rk_modem: rk-modem {
+        compatible="4g-modem-platdata";
+        4G,power-gpio = <&gpio4 RK_PD2 GPIO_ACTIVE_LOW>; //4G/5G_EN-MODEM_ON-GPIO4_D2
+        4G,reset-gpio = <&gpio0 RK_PD5 GPIO_ACTIVE_HIGH>;//4G/5G_RST-MODEM_RST-GPIO0_D5
+        status = "okay";
+    };

2. 


RK3568\kernel\drivers\usb\serial\option.c
+static const struct usb_device_id option_ids[] = {
+		#if 1 //Added by Quectel
+		{ USB_DEVICE(0x2C7C, 0x0125) }, /* Quectel EC20 R2.0/EC20 R2.1/EC25/EG25-G/EM05 */
+		{ USB_DEVICE(0x2C7C, 0x0121) }, /* Quectel EC21/EG21-G */
+		{ USB_DEVICE(0x2C7C, 0x0191) }, /* Quectel EG91 */
+		{ USB_DEVICE(0x2C7C, 0x0195) }, /* Quectel EG95 */
+		{ USB_DEVICE(0x2C7C, 0x0306) }, /* Quectel EG06/EP06/EM06 */
+		{ USB_DEVICE(0x2C7C, 0x0512) }, /* Quectel EG12/EM12/EG18 */
+		{ USB_DEVICE(0x2C7C, 0x0296) }, /* Quectel BG96 */
+		{ USB_DEVICE(0x2C7C, 0x0700) }, /* Quectel BG95/BG77/BG600L-M3/BC69 */
+		{ USB_DEVICE(0x2C7C, 0x0435) }, /* Quectel AG35 */
+		{ USB_DEVICE(0x2C7C, 0x0415) }, /* Quectel AG15 */
+		{ USB_DEVICE(0x2C7C, 0x0452) }, /* Quectel AG520R */
+		{ USB_DEVICE(0x2C7C, 0x0455) }, /* Quectel AG550R */
+		{ USB_DEVICE(0x2C7C, 0x0620) }, /* Quectel EG20 */
+		{ USB_DEVICE(0x2C7C, 0x0800) }, /* Quectel RG500Q/RM500Q/RG510Q/RM510Q */	
+		{ USB_DEVICE(0x1E0E,0x9001),//SIM8200EAM2
+		 .driver_info = RSVD(4) | RSVD(5) | RSVD(6) | RSVD(6)},
+	#endif

3. Makefile添加qmi_wwan_q.c（特别注意要放在qmi_wwan.o的前面），资源见附件EC25资料


RK3568\kernel\drivers\net\usb\Makefile
+obj-$(CONFIG_USB_NET_QMI_WWAN)	+= qmi_wwan_q.o
obj-$(CONFIG_USB_NET_QMI_WWAN)	+= qmi_wwan.o

4.menuconfig 确保如下使能

CONFIG_USB_NET_DRIVERS=y
CONFIG_USB_USBNET=y
CONFIG_NETDEVICES=y
CONFIG_USB_NET_CDCETHER=y
CONFIG_USB_NET_QMI_WWAN=y
CONFIG_USB_WDM=y

5.添加cdc-wdm0节点：

RK3568\system\core\init\devices.cpp
void DeviceHandler::HandleUevent(const Uevent& uevent) {if (uevent.action == "add" || uevent.action == "change" || uevent.action == "online") {FixupSysPermissions(uevent.path, uevent.subsystem);}// if it's not a /dev device, nothing to doif (uevent.major < 0 || uevent.minor < 0) return;std::string devpath;std::vector<std::string> links;bool block = false;if (uevent.subsystem == "block") {block = true;devpath = "/dev/block/" + Basename(uevent.path);if (StartsWith(uevent.path, "/devices")) {links = GetBlockDeviceSymlinks(uevent);}} else if (const auto subsystem =std::find(subsystems_.cbegin(), subsystems_.cend(), uevent.subsystem);subsystem != subsystems_.cend()) {devpath = subsystem->ParseDevPath(uevent);} else if (uevent.subsystem == "usb") {if (!uevent.device_name.empty()) {devpath = "/dev/" + uevent.device_name;} else {// This imitates the file system that would be created// if we were using devfs instead.// Minors are broken up into groups of 128, starting at "001"int bus_id = uevent.minor / 128 + 1;int device_id = uevent.minor % 128 + 1;devpath = StringPrintf("/dev/bus/usb/%03d/%03d", bus_id, device_id);}
+				#if 1 //add by quectel for mknod /dev/cdc-wdmo
+					} else if (uevent.subsystem == "usbmisc" && !uevent.device_name.empty()) {
+							   devpath = "/dev/" + uevent.device_name;
+				#endif		} else if (StartsWith(uevent.subsystem, "usb")) {// ignore other USB eventsreturn;} else {devpath = "/dev/" + Basename(uevent.path);}mkdir_recursive(Dirname(devpath), 0755);HandleDevice(uevent.action, devpath, block, uevent.major, uevent.minor, links);// Duplicate /dev/ashmem device and name it /dev/ashmem<boot_id>.// TODO(b/111903542): remove once all users of /dev/ashmem are migrated to libcutils API.HandleAshmemUevent(uevent);
}

6.重新编译boot.img，确保有如下节点
console:/ $ su                                                                 
console:/ # 
console:/ # ls -l dev/ttyUSB*
crw-rw-rw- 1 radio radio 188,   0 2022-01-27 12:33 dev/ttyUSB0
crw-rw-rw- 1 radio radio 188,   1 2022-01-27 12:33 dev/ttyUSB1
crw-rw-rw- 1 radio radio 188,   2 2022-01-27 14:02 dev/ttyUSB2
crw-rw-rw- 1 radio radio 188,   3 2022-01-27 12:33 dev/ttyUSB3
console:/ # 
console:/ # ls -l dev/cdc-wdm0                                                 
crw-rw---- 1 radio radio 180, 176 2022-01-27 12:33 dev/cdc-wdm
 

7.将厂家给的文件放到\vendor\rockchip\common\phone下，


rk3568\vendor\rockchip\common\phone\phone.mk
