nrfutil for Border Router

Question

I am working with Thread on the nRF52840 and have setup a few nodes and a Border Router 1.0.0 as described in the documentation using Raspberry Pi 3B+.

My sdk is nRF5_SDK_for_Thread_and_Zigbee_v1.0.0

Is it possible to run nrfutil on the Raspberry Pi?

I tried the following on Rasp Pi:

sudo apt-get update

sudo apt-get install python-pip

sudo pip install nrf util

It seemed to successfully install, but I'm thinking it's intended for a PC, not ARM.

I followed the Thread Secure DFU example using my PC successfully, and then prepared another package (appdfu_package_3.zip) with a minor change to the client code.

I ran nrfutil as before, only this time on the Raspberry Pi within the Border Router. I left off the -f option, since the Border Router is already connected to a DK board running NCP.

nrfutil dfu thread -pkg appdfu_package_3.zip --channel 11 --panid 43981 -r 8 -rs 5000 -a FF03::1

The libraries is said it couldn't find are in fact there. But I suspect they are compiled for x86 and not ARM, given the path name.

I saw an older post https://devzone.nordicsemi.com/f/nordic-q-a/15509/trying-to-use-a-nrfutil-command-on-raspbian-os describing how to compile nrfutil from source, but it's a bit old and doesn't mention these libraries.

Is this possible? Any plans to provide nrfutil for ARM?
