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 |
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
