Hi, I'm tring to generate private key of dfu, but it didn't work fine.The following is my steps.Did I miss something?

Hi,

The nrfutil that comes with nRFgo-Studio seems to be quite old(version 0.3.0), and it used a different syntax then.

I recommend to use an updated version. See here on how to download and install nrfutil, or use the nrfutil I have attached here:

nrfutil version 2.0.0
