	巨大八爪鱼：option.c、qcserial.c和usb_wwan.c這三個文件，瑞芯微SDK的linux內核裡面Luckfox_Nova_SDK_250430/kernel/drivers/usb/serial本來就有，默認是沒有開啟編譯的。如果想用內核裡面自帶的這三個文件，就得按照Quectel_LTE&5G_Linux_USB_Driver_User_Guide_V2.0.pdf文檔說明去改裡面的代碼。不過我看到option.c裡面已經有{ USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID, QUECTEL_PRODUCT_EC200A, 0xff, 0, 0) }了，這個不用添加了，其他地方比如URB_ZERO_PACKET還有return -ENODEV可能還是得自己手動加，有點麻煩。涉及到的三個c文件的menuconfig菜單項： option.c USB_SERIAL_OPTION "USB driver for GSM and CDMA modems" qcserial.c USB_SERIAL_QUALCOMM "USB Qualcomm Serial modem" 只要勾選了上面兩項中的任意一項，都會編譯usb_wwan.c。所以我覺得在內核外面編譯現成的Quectel_Linux_USB_Serial_Option_Driver_V1.0/v5.3.1代碼就行了，得到usb_wwan.ko、option.ko和qcserial.ko這三個文件，然後在板子上insmod這三個文件。確保內核menuconfig裡面沒有勾選上面所說的兩個菜單項（或者勾選為M），不然兩份代碼會有衝突。 insmod usb_wwan.ko insmod option.ko insmod qcserial.ko 內核裡面的菜單項勾選為m的話，會在內核目錄裡面生成ko文件，不用insmod他那裡面的ko文件，insmod內核外面單獨編譯的v5.3.1裡面的ko文件就行。

記得修改Quectel_LTE5G_Linux_USB_Driver_V1.0-5/Quectel_Linux_USB_Serial_Option_Driver_V1.0/v5.3.1/drivers/usb/serial/option.c源文件，在

static const struct usb_device_id option_ids[] = {

#if 1 //Added by Quectel

最後面添加{ USB_DEVICE(0x2C7C, 0x6005) },（就是板子lsusb命令裡面看到的2c7c後面那個數字）

這樣insmod option.ko後才會出現/dev/ttyUSB0和/dev/ttyUSB1兩個串口設備。

可以用microcom進入串口終端，發送AT命令：

按Ctrl+X退出串口終端。

同樣要修改Quectel_LTE5G_Linux_USB_Driver_V1.0-5/Quectel_LinuxAndroid_QMI_WWAN_Driver_V1.1/qmi_wwan_q.c源文件，在

static const struct usb_device_id products[] = {

最後面添加{ QMI_FIXED_RAWIP_INTF(0x2C7C, 0x6005, 4) },

這樣insmod qmi_wwan_q.ko後才會出現/dev/cdc-wdm0這個設備文件。

巨大八爪鱼：

沒有/dev/cdc-wdm0文件的話，quectel-CM程序無法運行成功。

正常情況下，只要插了USB線，開機後就會有ifconfig usb0接口，IP位址為192.168.43.100，不需要insmod GobiNet.ko。

如果沒有usb0接口，說明模塊當前所處的模式不對。這個時候即使insmod GobiNet.ko，usb0接口也不會出現。

	巨大八爪鱼：AT+QCFG="usbnet" 是Quectel 系列4G/5G模塊（如EC20、RM500、RG200U等）的AT指令，用於配置USB網絡接口模式，即指定模塊通過USB連接時使用的網絡協議標準。‌ ‌指令格式與參數‌ ‌測試命令‌：AT+QCFG=? 可查詢支持的參數值，響應中會列出可用的模式。‌ ‌設置命令‌：AT+QCFG="usbnet",<net>，其中 <net> 為模式參數： 0：RMNET 接口（高通標準，通常用於Linux內核驅動）。‌ 1：ECM（ECM 接口，USB設備通信模式，常見於Linux系統）。‌ 2：MBIM（MBIM 接口，微軟標準，支持高級功能）。‌ 3：RNDIS（RNDIS 接口，Windows兼容模式，也可在Linux中使用）。‌ ‌響應‌：成功時返回 OK，失敗時返回 ERROR；若省略參數（如 AT+QCFG="usbnet"），會返回當前配置狀態。‌ ‌配置步驟與注意事項‌ ‌連接與驗證‌：通過串口工具（如minicom）連接模塊的調試埠（如 /dev/ttyUSB0），發送 AT 測試通信是否正常。‌ ‌設置模式‌：例如，設置為ECM模式（自動撥號常用）：AT+QCFG="usbnet",1。‌ ‌重啟生效‌：配置後需重啟模塊（如發送 AT+CFUN=1,1）使設置生效。‌ ‌系統識別‌：重啟後，系統會生成新的網絡接口（如 usb0），可通過 ifconfig 或 ip a 查看IP位址分配。‌

	巨大八爪鱼：AT+CFUN=1,1 是AT指令中用於控制模塊功能的命令，具體作用是將模塊設置為全功能模式並執行重啟操作。‌ ‌命令含義‌：AT+CFUN 指令用於設定電話功能水平。參數 1 表示全功能模式，即啟用模塊的所有功能（如無線通信、SIM卡操作等）；參數 1 作為第二個值，指示執行重啟。重啟後，模塊會重新初始化並進入全功能狀態。 ‌典型應用場景‌：該命令常用於模塊初始化階段，以確保所有功能正常啟動。‌ 例如，在設備上電或故障恢復時，通過此指令激活模塊並重啟，以便後續執行其他操作（如查詢SIM卡狀態或網絡註冊）。‌ ‌執行注意事項‌：發送此命令後，模塊會重啟，期間可能需要約 4 秒時間完成初始化。重啟後，建議等待片刻再發送後續指令（如查詢 IMSI 或信號強度），以避免響應錯誤。‌此外，確保SIM卡已正確插入且為USIM卡，以避免功能異常。‌

目前，板子開機後，不需要insmod GobiNet.ko，就有usb0網絡接口。
GobiNet.ko並沒有起到作用，insmod GobiNet.ko也沒有匹配到任何設備。

EC200A這個USB設備上面有0-4這五個接口（interface），五個接口的名字分別為：
root@rk3308b-buildroot:/# cat /sys/bus/usb/devices/2-1/2-1:1.0/interface
Mobile RNDIS Network Adapter
root@rk3308b-buildroot:/# cat /sys/bus/usb/devices/2-1/2-1:1.1/interface
Mobile RNDIS Network Adapter
root@rk3308b-buildroot:/# cat /sys/bus/usb/devices/2-1/2-1:1.2/interface
Mobile Diag Interface
root@rk3308b-buildroot:/# cat /sys/bus/usb/devices/2-1/2-1:1.3/interface
Mobile AT Interface
root@rk3308b-buildroot:/# cat /sys/bus/usb/devices/2-1/2-1:1.4/interface
Mobile MODEM Interface
root@rk3308b-buildroot:/#

板子開機後，在沒有插入任何模塊的情況下，接口0和1匹配的是linux內核自帶的Luckfox_Nova_SDK_250430/kernel/drivers/net/usb/rndis_host.c驅動，接口2-4沒有匹配驅動。usb0網絡接口就是由內核自帶的rndis_host.c驅動產生的。

如果想要讓GobiNet.ko起作用，就需要修改Quectel_LTE5G_Linux_USB_Driver_V1.0-5/Quectel_LinuxAndroid_GobiNet_Driver_V1.6/GobiUSBNet.c文件，找到static const struct usb_device_id QuecGobiVIDPIDTable，在裡面加上GOBI_FIXED_INTF( 0x2c7c, 0x6005 )。
因為static struct driver_info GobiNetInfo裡面第1996行data=(1 << 4)，而在第755-761行有下面的代碼
   // Verify correct interface (4 for UC20)
   if ( !test_bit(pIntf->cur_altsetting->desc.bInterfaceNumber, &pDev->driver_info->data))
   {
      DBG( "invalid interface %d\n",
           pIntf->cur_altsetting->desc.bInterfaceNumber );
      return -ENODEV;
   }
所以最後GobiUSBNet.ko會匹配上接口4。
在內核外編譯GobiNet驅動代碼，並將GobiNet.ko上傳到板子上。
adb push "\\OCT1158-UBUNTU\oct1158\Documents\Code\C\Quectel_LTE5G_Linux_USB_Driver_V1.0-5\Quectel_LinuxAndroid_GobiNet_Driver_V1.6\GobiNet.ko" /root
在板子上插入GobiNet.ko模塊，可以看到又出現了新的usb1接口，這才是GobiUSBNet.ko產生的網絡接口。

可以看到，GobiNet.ko確實匹配的是4號接口（Mobile MODEM Interface），產生了usb1網絡接口。
linux內核自帶的Luckfox_Nova_SDK_250430/kernel/drivers/net/usb/rndis_host.c驅動依然還是匹配接口0-1（Mobile RNDIS Network Adapter），產生的是usb0網絡接口。

設置命令：AT+QNETDEVCTL=<connect_type>[,<CID>[,<URC_switch>]]
AT+QNETDEVCTL=1,1,1是單次手動連接。
AT+QNETDEVCTL=3,1,1是每次上電都自動連接。
AT+QNETDEVCTL=0是斷開網絡連接。
第二個參數表示PDP上下文索引號，範圍為1~7。第三個參數表示是否開啟URC上報。

查詢命令：AT+QNETDEVCTL?
響應格式：+QNETDEVCTL: <connect_type>,<CID>,<URC_switch>,<PDN_status>
例如+QNETDEVCTL: 3,1,1,1
查詢返回的第四個數PDN_status是網卡連接狀態。1表示已連接，0表示未連接。

理論上，stm32實現一個usb rndis驅動，就可以綁定lwip協議棧驅動4g模塊高速上網了，不使用4g模塊本身的AT指令TCP和UDP功能。

EC200A和EC200M的區別：

EC200ACNV1-CAT4模塊3孔轉板QTMHXB0036QD cat4:下行速率：150Mbps,上行速率：50Mbps

EC200MCNLF-CAT1模塊3孔轉板QTMHXB0037QD cat1:下行速率：10Mbps,上行速率：5Mbps

賣家說了，兩款都沒有GPS功能。

要想正常使用qcserial.ko，同樣需要修改qcserial.c，否則沒法匹配上usb設備。

static const struct usb_device_id id_table[]裡面在

{USB_DEVICE(0x0AF0, 0x8120)}, /* Option GTM681W */

後面添加

{USB_DEVICE(0x2C7C, 0x6005)},

在qcprobe函數裡面找到case QCSERIAL_G2K:

把

if (nintf == 5 && id->idProduct == QUECTEL_EC20_PID) {

改成

if (nintf == 5 && (id->idProduct == QUECTEL_EC20_PID || id->idProduct == 0x6005)) {

然後重新編譯。

insmod usb_wwan.ko和qcserial.ko後，就會出現/dev/ttyUSB0和/dev/ttyUSB1。/dev/ttyUSB1裡面也可以正常收發AT命令。

這說明，qcserial.ko和option.ko的作用是相同的，都是在USB接口2和3上產生ttyUSB0和ttyUSB1兩個設備。
