Android4.2 Quectel EC20 R2.1模組移植
注意： 本文件不支援熱插拔，本文使用GobiNET方式實現4G上網，並沒使用PPPD模式。
1、核心部分的移植 1.1 usb串列埠驅動的修改 修改： autochips/kernel/drivers/usb/serial/option.c kernel/drivers/usb/serial/qcserial.c kernel/drivers/usb/serial/usb_wwan.c 修改：autochips/kernel/drivers/usb/serial/option.c 檔案，新增EC20模組的註冊時的VID和PID號，以及生成裝置階段的介面4用於網路裝置，如下： static const struct usb_device_id option_ids[] = { ..................................................................................... { USB_DEVICE(QUALCOMM_VENDOR_ID, 0x6000)}, /* ZTE AC8700 */ { USB_DEVICE(QUALCOMM_VENDOR_ID, 0x6613)}, /* Onda H600/ZTE MF330 */ { USB_DEVICE(QUALCOMM_VENDOR_ID, 0x9000)}, /* SIMCom SIM5218 */ //EC20 yiyuan 4G LTE module configure #if 1//Added by Quectel { USB_DEVICE(0x05C6, 0x9090) }, /* Quectel UC15 */ { USB_DEVICE(0x05C6, 0x9003) }, /* Quectel UC20 */ { USB_DEVICE(0x05C6, 0x9215) }, /* Quectel EC20 */ { USB_DEVICE(0x2C7C, 0x0125) }, /* Quectel EC25/EC20 R2.0 */ { USB_DEVICE(0x2C7C, 0x0121) }, /* Quectel EC21 */ #endif
printk("option_probe, 1\n"); #if 1 //Added by Quectel //Quectel UC20's interface 4 can be used as USB Network device if (serial->dev->descriptor.idVendor == 0x05C6 && serial->dev->descriptor.idProduct == 0x9003 && serial->interface->cur_altsetting->desc.bInterfaceNumber >= 4) return -ENODEV; //Quectel EC20's interface 4 can be used as USB Network device if (serial->dev->descriptor.idVendor == 0x05C6 && serial->dev->descriptor.idProduct == 0x9215 && serial->interface->cur_altsetting->desc.bInterfaceNumber >= 4) return -ENODEV; if (serial->dev->descriptor.idVendor == cpu_to_le16(0x2C7C) && serial->interface->cur_altsetting->desc.bInterfaceNumber >= 4) return -ENODEV; #endif
修改：kernel/drivers/usb/serial/qcserial.c 去掉檔案中跟移遠4G模組VID和PID相沖突的選項，如下： static const struct usb_device_id id_table[] = { ...................................................................... {USB_DEVICE(0x05c6, 0x9214)}, /* Acer Gobi 2000 QDL device (VP413) */ //for EC20 yiyuan module remove //{USB_DEVICE(0x05c6, 0x9215)}, /* Acer Gobi 2000 Modem device (VP413) */ {USB_DEVICE(0x05c6, 0x9264)}, /* Asus Gobi 2000 QDL device (VR305) */ ................................................................................. } 修改：kernel/drivers/usb/serial/usb_wwan.c檔案，將移遠模組在USB串列埠urb資料上傳時使用0資料包處理，資料上行和下行使用USB網路介面，修改如下： static struct urb *usb_wwan_setup_urb(struct usb_serial *serial, int endpoint, int dir, void *ctx, char *buf, int len, void (*callback) (struct urb *)) { struct urb *urb;
if (endpoint == -1) return NULL; /* endpoint not needed */
urb = usb_alloc_urb(0, GFP_KERNEL); /* No ISO */ if (urb == NULL) { dbg("%s: alloc for endpoint %d failed.", __func__, endpoint); return NULL; }
/* Fill URB using supplied data. */ usb_fill_bulk_urb(urb, serial->dev, usb_sndbulkpipe(serial->dev, endpoint) | dir, buf, len, callback, ctx); //add for EC20 yiyuan #if 1//Added by Quectel for Zero Packet struct usb_device_descriptor *desc = &serial->dev->descriptor; if (desc->idVendor == cpu_to_le16(0x05C6) && desc->idProduct == cpu_to_le16(0x9090)) urb->transfer_flags |= URB_ZERO_PACKET; if (desc->idVendor == cpu_to_le16(0x05C6) && desc->idProduct == cpu_to_le16(0x9003)) urb->transfer_flags |= URB_ZERO_PACKET; if (desc->idVendor == cpu_to_le16(0x05C6) && desc->idProduct == cpu_to_le16(0x9215)) urb->transfer_flags |= URB_ZERO_PACKET; if (desc->idVendor == cpu_to_le16(0x2C7C)) urb->transfer_flags |= URB_ZERO_PACKET; #endif //end EC20 return urb; } 1.2USB網路介面的修改 移遠的4G模組使用Gobinet驅動來實現網路資料的上行和下行，方法如下： 將移遠提供的驅動包中的檔案放到 kernel/drivers/net/usb/GobiUSBNet.c kernel/drivers/net/usb/QMI.c kernel/drivers/net/usb/QMI.h kernel/drivers/net/usb/QMIDevice.c kernel/drivers/net/usb/QMIDevice.h kernel/drivers/net/usb/Structs.h 修改kernel/drivers/net/usb/Makefile，新增編譯選項，如下：obj-y += GobiNet.o GobiNet-objs := GobiUSBNet.o QMIDevice.o QMI.o obj-$(CONFIG_USB_CATC) += catc.o 修改kernel/drivers/net/usb/qmi_wwan.c USB網路介面驅動，新增EC2.1模組的VID和PID，將GobiNet驅動跟USB網路驅動連結到一起，將檔案系統介面的ttyUSB訪問時轉接到GobiNet驅動上，同時去掉介面中針對移遠模組的舊的VID、PID配置，修改如下： static const struct usb_device_id products[] = { .............................................................................. {QMI_GOBI_DEVICE(0x03f0, 0x251d)}, /* HP Gobi 2000 Modem device (VP412) */ //{QMI_GOBI_DEVICE(0x05c6, 0x9215)}, /* Acer Gobi 2000 Modem device (VP413) */ {QMI_GOBI_DEVICE(0x05c6, 0x9265)}, /* Asus Gobi 2000 Modem device (VR305) */ ............................................................................... {QMI_GOBI_DEVICE(0x1199, 0x901b)}, /* Sierra Wireless MC7770 */ #if 1//Added by Quectel //{QMI_GOBI_DEVICE(0x05C6, 0x9090) }, /* Quectel UC15 */ //{QMI_GOBI_DEVICE(0x05C6, 0x9003) }, /* Quectel UC20 */ {QMI_GOBI_DEVICE(0x05c6, 0x9215)}, //For Quectel EC20 {QMI_GOBI_DEVICE(0x2C7C, 0x0125)}, //For Quectel EC20 {QMI_GOBI_DEVICE(0x2C7C, 0x0121)}, //For Quectel EC20 #endif
{ } /* END */ }; 1.3 核心配置檔案修改 修改：autochips/kernel/arch/arm/configs/ac83xx_defconfig 新增ppp的配置選項：CONFIG_PPP=y CONFIG_PPP_BSDCOMP=y CONFIG_PPP_DEFLATE=y CONFIG_PPP_FILTER=y CONFIG_PPP_MPPE=y CONFIG_PPP_MULTILINK=y CONFIG_PPPOE=y CONFIG_PPPOL2TP=y CONFIG_PPPOLAC=y CONFIG_PPPOPNS=y CONFIG_PPP_ASYNC=y CONFIG_PPP_SYNC_TTY=y CONFIG_SLHC=y USB網路的配置：CONFIG_USB_USBNET=y ---------->必選 CONFIG_USB_NET_AX8817X=y CONFIG_USB_NET_CDCETHER=y CONFIG_USB_NET_CDC_NCM=y CONFIG_USB_NET_NET1080=y CONFIG_USB_NET_CDC_SUBSET=y CONFIG_USB_BELKIN=y CONFIG_USB_ARMLINUX=y CONFIG_USB_NET_ZAURUS=y USB串列埠配置：CONFIG_USB_SERIAL=y CONFIG_USB_SERIAL_GENERIC=y CONFIG_USB_SERIAL_WWAN=y CONFIG_USB_SERIAL_OPTION=y 2、HAL的配置 2.1 刪除ATC平臺本身自帶的與ril層撥號相關的部分 首先刪除本身ATC平臺之前除錯3G模組針對電話網路部分的修改，主要有chat、ip-down、ip-up、rild以及reference-ril，這個幾個部分跟EC2.1模組的ril層使用有衝突，不去掉編譯將報錯誤或者在ril層撥號時不成功。刪除部分如下： autochips/hardware/ril/ autochips/external/chat/Android.mk autochips/external/ppp/android/Android.mk autochips/device/atc/ac8317/.overlay/hardware/ril/ 1)刪除autochips/hardware/ril 這個目錄 2)刪除autochips/device/atc/ac8317/.overlay/hardware/ril 這個目錄 3) 修改autochips/external/chat/Android.mk檔案，去掉編譯選項，如下：#ifeq ($(TARGET_ARCH),arm) ifeq ($(TARGET_ARCH), ) .................................... } 或將android.mk修改成android_mk,如下： autochips/external/chat/Android_mk 去掉自帶chat的編譯 4) 將autochips/external/ppp/android/Android.mk修改成： autochips/external/ppp/android/Android_mk.bak 將autochips/external/ppp/android/目錄下的檔案不編譯進系統。 2.2 新增EC2.1模組的ril層程式碼 2.2.1 如果是原始碼程式碼，請按照以下方式 將移遠提供的EC2.1模組的ril程式碼reference-ril資料夾新增到hardware/ril/目錄中，替換掉系統中自帶的hardware/ril/reference-ril/目錄，如下：hardware/ril/reference-ril_bak/ hardware/ril/reference-ril_bak/Android_mk hardware/ril/reference-ril/ 2.2.2 如果提供的是二進位制檔案和庫，請使用如下方式修改 去掉系統自帶的的hardware/ril/reference-ril/目錄 hardware/ril/reference-ril_bak/ hardware/ril/reference-ril_bak/Android_mk 在autochips/hardware/ril/目錄或者hardware/ril/目錄中建立reference-ril目錄，將廠家提供的二進位制檔案放到reference-ril目錄中，mtk平臺放到autochips/hardware/ril/reference-ril/目錄下，其它平臺放到hardware/ril/reference-ril/目錄下，如下：autochips/hardware/ril/reference-ril/Android.mk autochips/hardware/ril/reference-ril/ip-up autochips/hardware/ril/reference-ril/ip-down autochips/hardware/ril/reference-ril/chat autochips/hardware/ril/reference-ril/libreference-ril.so 修改autochips/hardware/ril/reference-ril/Android.mk 內容如下：LOCAL_PATH := $(call my-dir) ############################################################### # copy the shell script to etc/ppp # ############################################################### include $(CLEAR_VARS) LOCAL_MODULE := ip-up #LOCAL_MODULE_TAGS := optional LOCAL_MODULE_CLASS := ETC LOCAL_MODULE_PATH := $(TARGET_OUT_ETC)/ppp LOCAL_SRC_FILES := $(LOCAL_MODULE) include $(BUILD_PREBUILT)

5.測試並進行驗證 修改配置完成後使用 $source selfenv newui $./selfbuild cpoverlay newui $./selfbuild 編譯整個系統，編譯完成後，將system、ramdisk、kernel三個部分做升級包升級到系統中。 插入4G模組，開機啟動。之後按照第4章中的說明將Settings.apk、SettingsProvider.apk、SystemUI.apk、Phone.apk 四個APK push到flysystem/app目錄中替換掉之前的APK，然後插入4G模組，在設定選單中選擇“更多”---->”行動網路”------>”網路模式”---------->”LTE/CDMA”選項打勾，點選”確定”即可。 插入4G模組之後一會就可以看到 4G圖示了。 有問題時抓取radio log。 #adb shell #logcat -b radio 抓取radio的日誌，看是否撥號成功，成功之後，使用ping和netstat看網路狀態。 [email protected]:/ # netstat Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 127.0.0.1:5037 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:5038 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:5040 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:7000 0.0.0.0:* LISTEN tcp6 1 0 ::ffff:10.153.50.37:36212 ::ffff:74.125.204.102:443 SYN_SENT tcp6 1 1 ::ffff:10.153.50.37:37211 ::ffff:220.181.163.3:80 LAST_ACK tcp6 0 1 ::ffff:10.153.50.37:55686 ::ffff:183.129.161.214:80 CLOSE_WAIT [email protected]:/ # ping www.baidu.com PING www.a.shifen.com (14.215.177.39) 56(84) bytes of data. 64 bytes from 14.215.177.39: icmp_seq=1 ttl=53 time=21.9 ms 64 bytes from 14.215.177.39: icmp_seq=2 ttl=53 time=35.2 ms 64 bytes from 14.215.177.39: icmp_seq=3 ttl=53 time=30.1 ms 64 bytes from 14.215.177.39: icmp_seq=4 ttl=53 time=32.7 ms 64 bytes from 14.215.177.39: icmp_seq=5 ttl=53 time=31.9 ms
注意：在4G模組插入的時候會彈出對話方塊，選擇”暫時不用”，否則4G網路會存在不能使用的問題
