全志平台华为4G模块开发调试记录

以下技术在盈鹏飞嵌入式的A40I/T3核心板(CoM-X40I)和主控板(SBC-X40I)上经过验证,欢迎 交流! CoM-X40I核心板和SBC-X40I主板见下图:

1. 前言

因为需要适配4G模块，这里总结下整个调试过程；

2. linux部分

linux 部分主要是硬件识别，当拿到模块后，插入板子上，打印如下：

  1. [  185.120132] usb 3-1: new high-speed USB device number 2 using xhci-hcd
  2. [  185.141610] usb 3-1: New USB device found, idVendor=12d1, idProduct=15c1
  3. [  185.149447] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
  4. [  185.157830] usb 3-1: Product: HUAWEI Mobile V7R11
  5. [  185.164667] usb 3-1: Manufacturer: Huawei Technologies Co., Ltd.
  6. [  185.171450] usb 3-1: SerialNumber: 0123456789ABCDEF
  7. [  185.251621] cdc_ether 3-1:2.0 usb0: register 'cdc_ether' at usb-xhci-hcd.0.auto-1, CDC Ethernet Device, 02:1e:10:1f:00:00
  8. [  185.271723] option 3-1:2.2: GSM modem (1-port) converter detected
  9. [  185.286827] usb 3-1: GSM modem (1-port) converter now attached to ttyUSB0
  10. [  185.295963] option 3-1:2.3: GSM modem (1-port) converter detected
  11. [  185.304478] usb 3-1: GSM modem (1-port) converter now attached to ttyUSB1
  12. [  185.313672] option 3-1:2.4: GSM modem (1-port) converter detected
  13. [  185.320886] CPU1: Booted secondary processor
  14. [  185.320886] CPU1: update cpu_power 1024
  15. [  185.332151] usb 3-1: GSM modem (1-port) converter now attached to ttyUSB2
  16. [  185.341133] option 3-1:2.5: GSM modem (1-port) converter detected
  17. [  185.350048] usb 3-1: GSM modem (1-port) converter now attached to ttyUSB3
  18. [  185.358760] option 3-1:2.6: GSM modem (1-port) converter detected
  19. [  185.367116] usb 3-1: GSM modem (1-port) converter now attached to ttyUSB4

从打印可以看出如下信息： （1）USB串口驱动正常工作，设备加载正常。 （2）CDC ECM驱动正常工作。 （3）一共生成了5个虚拟的串口。

3. android部分

3.1 RIL库的移植

在init.rc中添加服务如下：service ril-daemon /system/bin/rild -l libhuawei-ril.so

其中rild源码在/hardware/ril/rild/目录下， 然后将libhuawei-ril.so放到system/lib/目录中，在device/softwinner/common/目录下，新建文件夹LTE/，在该目录中添加文件firmware-LTE.mk， 然后将libhuawei-ril.so文件放入该目录，在firmware-LTE.mk中添加内容如下：

修改device/softwinner/petrel-p1，添加内容如下：

3.2 修改使用的USB或者PCM端口的权限

device/softwinner/petrel-p1目录中，添加如下内容：

3.3 手动测试模组拨号过程

（1）这时候可以借用SDK中PPP源码（对应目录为external/ppp）编译出来的pppoe可执行程序。 首先将部分linux-ppp-script中的相关文件拷贝到SDK中的对应目录，如下：

（2）同时，需要修改huawei-ppp-on脚本，内容如下：

  1. #!/bin/sh
  2. #
  3. # Script to initiate a ppp connection. This is the first part of the
  4. # pair of scripts. This is not a secure pair of scripts as the codes
  5. # are visible with the 'ps' command.  However, it is simple.
  6. # Modify: fangxiaozhi <huananhu@huawei>
  7. programName=${0##*/}
  8. # These are the parameters. Change as needed.
  9. #DEVICE=/dev/usb/tts/0
  10. #DEVICE=/dev/ttyACM0                    #The modem file name of the data card
  11. DEVICE=/dev/ttyUSB0                     #The modem file name of the data card
  12. TELEPHONE=*99#                             # The telephone number for the connection, by default, it will be *99#
  13. ACCOUNT=""                              # The account name for logon, by default, it  will be null
  14. PASSWORD=""                         # The password for this account, by default, it  will be null
  15. AUTH=""                     # Authentic protocol,byi default, it will be null

  1. #define _PATH_PEERFILES  _ROOT_PATH "/etc/ppp/peers/"

4. 修改ip-up脚本

5. 运行huawei-ppp-on脚本

sh ./huawei-ppp-on --user=card --pwd=card --pn=*99# --auth=chap --apn=1234 正常情况下打印为：

  1.  
  2. er=card --pwd=card --pn=*99# --auth=chap --apn=1234                           <

  34. expect (CONNECT)
  35.  
  36. ATDT*99#^M^M
  37. CONNECT
  38.  -- got it
  39. send

6. 查看虚拟网卡

执行命令busybox ifconfig，可以看到生成了ppp0网口，如下：

但是此时是无法连接互联网的，因为没有配置dns

7. 查看dns

首先看下通过pppoe报文交互获得dns是什么，利用命令获取如下：getprop | grep dns

  1. [net.-ppp0.dns1]: [211.136.20.203]
  2. [net.-ppp0.dns2]: [211.136.17.107]

8. 配置dsn

  1. root@petrel-p1:/system/etc/ppp # setprop net.dns1 211.136.20.203
  2. root@petrel-p1:/system/etc/ppp # setprop net.dns2 211.136.17.107               
  3. root@petrel-p1:/system/etc/ppp # ndc resolver setifdns ppp0 "" 211.136.20.203
  4. 200 0 Resolver command succeeded
  5. root@petrel-p1:/system/etc/ppp # ndc resolver setdefaultif ppp0

9. ping百度

ping www.baidu
