You can use the nrf5sdk-tools pkg (or pkg) command to generate a package to use for a Device Firmware Update (DFU). The package contains the following:
- A new firmware image
- An init packet
- A manifest file that indicates the package format
The command can also be used to display the package contents.
Tip
For more information about the DFU process in the nRF5 SDK, see the nRF5 SDK Device Firmware Update process page.
