Description

Sub-command	Explanation
create	A manufacturing image specifies 1) a boot loader target, and 2) one or more image targets. Assuming the manufacturing entity has been created and defined in the mfgs/<mfg image name>/ package (see Examples below), this command collects the manufacturing related files in the newly created bin/mfgs/<mfg image name> directory. The collection includes the image file, the hex file, and the manifests with the image build time, version, manufacturing package build time, image ID (or hash) etc. It is essentially a snapshot of the image data and metadata uploaded to the device flash at manufacturing time. Note that the command expects the targets and images to have already been built using newt build and newt create-image commands.
deploy	A combination of build and load commands to put together and upload manufacturing image on to the device.
load	Loads the manufacturing package onto to the flash of the connected device.

Examples

Suppose you have created two targets (one for the bootloader and one for the blinky app).

$ newt target show
targets/my_blinky_sim
    app=apps/blinky
    bsp=@apache-mynewt-core/hw/bsp/native
    build_profile=debug
targets/rb_blinky
    app=apps/blinky
    bsp=@apache-mynewt-core/hw/bsp/rb-nano2
    build_profile=debug
targets/rb_boot
    app=@apache-mynewt-core/apps/boot
    bsp=@apache-mynewt-core/hw/bsp/rb-nano2
    build_profile=optimized

Create the directory to hold the mfg packages.

$ mkdir -p mfgs/rb_blinky_rsa

The rb_blinky_rsa package needs a pkg.yml file. In addition, it needs a mfg.yml file to specify the two constituent targets. An example of each file is shown below.

$  more mfgs/rb_blinky_rsa/pkg.yml
pkg.name: "mfgs/rb_blinky_rsa"
pkg.type: "mfg"
pkg.description:
pkg.author:
pkg.homepage:

$  more mfgs/rb_blinky_rsa/mfg.yml
mfg.bsp: "@apache-mynewt-core/hw/bsp/rb-nano2"
mfg.targets:
    - rb_boot:
      name: "targets/rb_boot"
      area: FLASH_AREA_BOOTLOADER
      offset: 0x0
    - rb_blinky:
      name: "targets/rb_blinky"
      area: FLASH_AREA_IMAGE_0
      offset: 0x0
mfg.meta:
    area: FLASH_AREA_BOOTLOADER

Build the bootloader and app images.

$ newt build rb_boot
$ newt create-image rb_blinky 0.0.1

Run the newt mfg create command to collect all the manufacturing snapshot files.

$ newt mfg create rb_blinky_rsa 0.0.1
