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.

|---|---|
|
Creates an image for target 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. |
