===================
Binary/Target Files
===================

These files should be used on the target device file system as follows:
AndroidFS/system/bin/swisdk
AndroidFS/system/bin/swifwdnld
AndroidFS/system/bin/swihltrace
AndroidFS/system/lib64/libsierra-ril.so
AndroidFS/system/lib64/libsierraat-ril.so
AndroidFS/system/lib64/libsierrahl-ril.so
AndroidFS/system/lib64/libswisdkapi.so
AndroidFS/system/bin/slqssdk
AndroidFS/system/bin/SierraDMLog
AndroidFS/system/bin/SierraFwDl7xxx
AndroidFS/system/bin/SierraImgMgr
AndroidFS/system/bin/SierraSARTool
AndroidFS/system/lib64/libswims.so
AndroidFS/system/lib64/libswiqmiapi.so
AndroidFS/system/app/com.sierra.logs/com.sierra.logs.apk
 - copy to the target device file system


AndroidFS/system/lib64/libswigpsqmi.so
 - for QMI RIL, copy to /system/lib64/hw on the target device file system and rename as 
   appropriate for the target device.
AndroidFS/system/lib64/libswigpsat.so 
 - for AT RIL, copy to /system/lib64/hw on the target device file system and rename as 
   appropriate for the target device.


AndroidFS/system/bin/init.dhcpcd
 - copy to the target device file system
 - if you already have an existing file by the same name, do not merge them
   but instead rename this file to something else, and update init.rc
   with that name.

AndroidFS/system/bin/init.config.ip
 - copy to the target device file system
 - IP config script for HL75xx series modem 

AndroidFS/init.rc
AndroidFS/ueventd.rc
 - these are taken from our Lollipop reference platform.
 - merge the Sierra specific changes into your files.  All Sierra changes 
   are surrounded by comments containing SWISTART and SWISTOP.
 - Note that some of the lines are only applicable to a different type of
   Sierra Wireless modem, and so can be omitted.  These lines are:
     insmod /system/lib/modules/sierra_net.ko


======================
Network Interface Name 
======================

The network interface name is "usbx" or "wwanx" for HL, QMI or AT RIL where x is an integer, usually 0 or 1.
The exact value depends on what other usb network devices are on the target device.  

The following files:

AndroidFS/system/bin/init.dhcpcd

are hard-coded with usb0/wwan0.  If this is not the correct network name on your 
target device, please change usb0/wwan0 to the correct name.





=========================
Switch between HL/AT/QMI RIL
=========================

QMI, HL and AT RIL are included in the release package. The default setting is QMI RIL.
It is possible to switch between them by change the system property:
steps:  1 sudo adb root
        2 adb remount
        3 adb shell setprop persist.sys.ril.type [HL | AT | QMI]
        4 adb reboot
