newtmgr image
--------------

Manage images on a device.

Usage:
^^^^^^

.. code-block:: console

        newtmgr image [command] -c <connection_profile> [flags]

Flags:
^^^^^^

The coredownload subcommand uses the following local flags:

.. code-block:: console

        -n, --bytes uint32         Number of bytes of the core to download
        -e, --elfify               Create an ELF file
            --offset unint32       Offset of the core file to start the download

Global Flags:
^^^^^^^^^^^^^

.. code-block:: console

      -c, --conn string       connection profile to use
      -h, --help              help for newtmgr
      -l, --loglevel string   log level to use (default "info")
          --name string       name of target BLE device; overrides profile setting
      -t, --timeout float     timeout in seconds (partial seconds allowed) (default 10)
      -r, --tries int         total number of tries in case of timeout (default 1)

Description
^^^^^^^^^^^

The image command provides subcommands to manage core and image files on a device. Newtmgr uses the ``conn_profile``
connection profile to connect to the device.

| Sub-command    | Explanation                                                                                                                                                                                                                                                                                         |
+================+=====================================================================================================================================================================================================================================================================================================+
| confirm        | The ``newtmgr image confirm [hex-image-hash]`` command makes an image setup permanent on a device. If a ``hex-image-hash`` hash value is specified, Mynewt permanently switches to the image identified by the hash value. If a hash value is not specified, the current image is made permanent.   |
+----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| coreconvert    | The ``newtmgr image coreconvert <core-filename> <elf-file>`` command converts the ``core-filename`` core file to an ELF format and names it ``elf-file``. **Note**: This command does not download the core file from a device. The core file must exist on your host.                              |
+----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| coredownload   | The ``newtmgr image coredownload <core-filename>`` command downloads the core file from a device and names the file ``core-filename`` on your host. Use the local flags under Flags to customize the command.                                                                                       |
+----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| coreerase      | The ``newtmgr image coreerase`` command erases the core file on a device.                                                                                                                                                                                                                           |
+----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| corelist       | The ``newtmgr image corelist`` command lists the core(s) on a device.                                                                                                                                                                                                                               |
+----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| erase          | The ``newtmgr image erase`` command erases an unused image from the secondary image slot on a device. The image cannot be erased if the image is a confirmed image, is marked for test on the next reboot, or is an active image for a split image setup.                                           |
+----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| list           | The ``newtmgr image list`` command displays information for the images on a device.                                                                                                                                                                                                                 |
+----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| test           | The ``newtmgr test <hex-image-hash>`` command tests the image, identified by the ``hex-image-hash`` hash value, on next reboot.                                                                                                                                                                     |
+----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| upload         | The ``newtmgr image upload <image-file>`` command uploads the ``image-file`` image file to a device.                                                                                                                                                                                                |
