全志平台华为4G模块调试记录1

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：

[  185.120132] usb 3-1: new high-speed USB device number 2 using xhci-hcd
[  185.141610] usb 3-1: New USB device found, idVendor=12d1, idProduct=15c1

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：

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

STR_USER="user \"card\""
STR_PASSWD="password \"card\""

show_usage(){

  exit 0
}

PID=`ps -ef | grep -v grep | grep "huawei-dial" | grep "pppd" | busybox awk '{ print $2; exit }'`

if test $PID; then
    echo "PPP link is active"
    exit 1

（3）需要修改external/pppd/pathname.h文件

#define _PATH_PEERFILES  _ROOT_PATH "/etc/ppp/peers/"
改成
#define _PATH_PEERFILES  _ROOT_PATH "/data/ppp/peers/"
