Dear All,


In reference to the NRF52840 Dongle Example, yesterday i send you the problem with the first step i.e. 

west build -b nrf52840_pca10059 zephyr/samples/basic/blinky
Now this step is going smoothly..
The second step ( 
nrfutil pkg generate --hw-version 52 --sd-req=0x00 \
        --application build/zephyr/zephyr.hex \
        --application-version 1 blinky.zip)
is giving the error message which is as follows: 
~/zephyrproject/zephyr/samples/basic/blinky$ nrfutil pkg generate --hw-version 52 --sd-req=0x00 \
>         --application build/zephyr/zephyr.hex \
>         --application-version 1 blinky.zip

Dear,


I am totally new in Zephyr. I am new in the field of IoT programming. I have gone through the tutorial of zephyr. Learned some things. But now i want to go through the Sample examples of Blink LED and Mesh Demo so that i can have a start off. I have tried to run the sample as per the instructions given in the tutorial but not successful. I will be grateful if you can help me in this regards. Waiting for the kind reply. Thank you in advance.
