ModemManager
|
|
============
|
|
|
|
Introduction
|
|
------------
|
|
|
|
This plugin adds support for devices managed by ModemManager.
|
|
|
|
GUID Generation
|
|
---------------
|
|
|
|
These device use the ModemManager "Firmware Device IDs" as the GUID, e.g.
|
|
|
|
* `USB\VID_413C&PID_81D7&REV_0318&CARRIER_VODAFONE`
|
|
* `USB\VID_413C&PID_81D7&REV_0318`
|
|
* `USB\VID_413C&PID_81D7`
|
|
* `USB\VID_413C`
|
|
|
|
Vendor ID Security
|
|
------------------
|
|
|
|
The vendor ID is set from the USB vendor, for example `USB:0x413C`
|
|
|
|
Update method: fastboot
|
|
-----------------------
|
|
|
|
If the device supports the 'fastboot' update method, it must also report which
|
|
AT command should be used to trigger the modem reboot into fastboot mode.
|
|
|
|
Once the device is in fastboot mode, the firmware upgrade process will happen
|
|
as defined e.g. in the 'flashfile.xml' file. Every file included in the CAB that
|
|
is not listed in the associated 'flashfile.xml' will be totally ignored during
|
|
the fastboot upgrade procedure.
|
|
|
|
Update Protocol: com.google.fastboot
|
|
|
|
Update method: qmi-pdc
|
|
----------------------
|
|
|
|
If the device supports the 'qmi-pdc' update method, the contents of the CAB
|
|
file should include files named as 'mcfg.*.mbn' which will be treated as MCFG
|
|
configuration files to download into the device using the Persistent Device
|
|
Configuration QMI service.
|
|
|
|
If a device supports both 'fastboot' and 'qmi-pdc' methods, the fastboot
|
|
operation will always be run before the QMI operation, so that e.g. the full
|
|
partition where the MCFG files are stored can be wiped out before installing
|
|
the new ones.
