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

Subject: Zephyr Sample Demo with nrf52840 Dongle

 

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.

Regards

Muhammad.

Hi Muhammad

I doubt anyone here can give you a better general write up then the documentation. So you need to provide information about the specific problem.

• Which exact instructions are you following
• What is your operating System and Toolchain
• Which version of Zephyr are you running
  
• Which steps are unclear / make you problems
• Where does it fail? What is the error output.
• Additional information

Best regards

Serafin
