Usage: nrfutil pkg generate [OPTIONS] ZIPFILE  Generate a zip package for distribution to apps that support Nordic DFU  OTA. The application, bootloader, and SoftDevice files are converted to  .bin if supplied as .hex files. For more information on the generated  package, see: http://developer.nordicsemi.com/nRF5_SDK/doc/  The following combinations are supported by this command:  * BL only: Supported.  * SD only: Supported (SD of same Major Version).  * APP only: Supported.  * BL + SD: Supported.  * BL + APP: Not supported (use two packages instead).  * BL + SD + APP: Supported.  * SD + APP: Supported (SD of same Major Version).Options:  --debug-mode                    Debug mode switch, enables version check                                  skipping.  --application TEXT              The application firmware file.  --application-version INTEGER   The application version.  --application-version-string TEXT                                  The application version string, e.g                                  "2.7.31".  --bootloader TEXT               The bootloader firmware file.  --bootloader-version INTEGER    The bootloader version.  --hw-version INTEGER            The hardware version.  --sd-req TEXT                   The SoftDevice requirements.
