| newt create-image |
| ------------------ |
| |
| Create and sign an image by adding an image header to the binary file created for a target. Version number in the header is set to <version>. To sign an image provide a .pem file for the signing-key and an optional key-id. |

| Description |
| ^^^^^^^^^^^ |
| |
| Adds an image header to the created binary file for the ``target-name`` target. The image version is set to ``version``. It creates a ``<app-name>.img`` file the image, where ``app-name`` is the value specified in the target ``app`` variable, and stores the file in the '/bin/targets/<target-name>/app/apps/<app-name>/' directory. It also creates a ``<app-name>.hex`` file for the image in the same directory, and adds the version, build id, image file name, and image hash to the ``manifest.json`` file that the ``newt build`` command created. |
| |
| To sign an image, provide a .pem file for the ``signing-key`` and an optional ``key-id``. ``key-id`` must be a value between 0-255. |

| Usage Explanation |
| ================================================== ================================================================================= |
| ``newt create-image myble2 1.0.1.0`` Creates an image for target ``myble2`` and assigns it version |
| ``1.0.1.0``. |
| |
| For the following target definition: |
| |
| | targets/myble2 |
| | app=\@apache-mynewt-core/apps/btshell |
| | bsp=\@apache-mynewt-core/hw/bsp/nrf52dk |
| | build\_profile=optimized |
| | syscfg=STATS\_NAMES=1 |
| |
| the 'bin/targets/myble2/app/apps/btshell/btshell.img' and |
| 'bin/targets/myble2/app/apps/btshell/btshell.hex' files are created, |
| and the manifest in 'bin/targets/myble2/app/apps/btshell/manifest.json' |
| is updated with the image information. |
| |
| ``newt create-image myble2 1.0.1.0 private.pem`` Creates an image for target ``myble2`` and assigns it the version |
| ``1.0.1.0``. Signs the image using private key specified by the private.pem file. |
