Management Subsystem
|
||
|
|
####################
|
||
|
|
|
||
|
|
Overview
|
||
|
|
********
|
||
|
|
|
||
|
|
The management subsystem allows remote management of Zephyr-enabled devices.
|
||
|
|
The following management operations are available:
|
||
|
|
|
||
|
|
* Image management
|
||
|
|
* File System management
|
||
|
|
* Log management (currently disabled)
|
||
|
|
* OS management
|
||
|
|
|
||
|
|
over the following transports:
|
||
|
|
|
||
|
|
* BLE (Bluetooth Low Energy)
|
||
|
|
* Serial (UART)
|
||
|
|
|
||
|
|
The management subsystem is based on the Simple Management Protocol (SMP)
|
||
|
|
provided by `MCUmgr`_, an open source project that provides a
|
||
|
|
management subystem that is portable across multiple real-time operating
|
||
|
|
systems.
|
||
|
|
|
||
|
|
The management subsystem is split in two different locations in the Zephyr tree:
|
||
|
|
|
||
|
|
* :file:`ext/lib/mgmt/mcumgr/` contains a clean import of the MCUmgr project
|
||
|
|
* :file:`subsys/mgmt/` contains the Zephyr-specific bindings to MCUmgr
|
||
|
|
|
||
|
|
Additionally there is a :ref:`sample <smp_svr_sample>` that provides management
|
||
|
|
functionality over BLE and serial.

Command-line Tool
|
||
|
|
*****************
|
||
|
|
|
||
|
|
MCUmgr provides a command-line tool, :file:`mcumgr`,for managing remote devices.
|
||
|
|
The tool is written in the Go programming language.
|
||
|
|
|
||
|
|
Installation information can be found in the `MCUmgr command-line tool`_
|
||
|
|
section of the `MCUmgr documentation`_. A full rundown of the necessary commands
|
||
|
|
to perform Device Firmware Upgrade is located in
|
||
|
|
`MCUmgr command-line tool examples`_, and a practical step-by-step guide to DFU
|
||
|
|
using MCUmgr can be found in :ref:`smp_svr_sample`.
|
||
|
|
|
||
|
|
Bootloader integration
|
||
|
|
**********************
|
||
|
|
|
||
|
|
The :ref:`dfu` subsystem integrates the management subsystem with the
|
||
|
|
bootloader, providing the ability to send and upgrade a Zephyr image to a
|
||
|
|
device.
|
||
|
|
|
||
|
|
Currently only the MCUboot bootloader is supported. See :ref:`mcuboot` for more
|
||
|
|
information.
