nrfutil keys generate issue

[Sunil vignesh]

Hi, I want to create bootloader for my code. For that I have install Python3 (Python 3.9.1)

followed by installing pip and nrfutil

python -m pip install --upgrade pip

pip install nrfutil

i found its installed nrfutil 5.2.0 but in online it showing nrfutil 6.1.0

and while i try to generate keys

in help it shows nrfutil keys --gen-key

it was not creating . What i have to do to generate keys for DFU

Normal user cannot write to c:\ per default.

Just omit the "c:\" and write in the current dir (c:\users\sunil).

Hello, for your "constants" problem, did you try the solution from https://devzone.nordicsemi.com/f/nordic-q-a/65889/nrfutil-modulenotfounderror-no-module-named-constants

It is important to show as much of your attempts at solving the problem as you can.

For Python, always look at the last lines in the call stack to give you a hint about the problem.
