Thread border router image for Raspberry Pi 4

[Den]

Hello,

I am working on the Nordic nRF52840 development board to create a thread network and I want to use Raspberry Pi4 as thread board border router. The nordic SDK provide prebuilt image for Raspberry pi 3b+. But I need this prebuild image or steps to create it for Raspberry Pi4. Please help to share the prebuild image for Raspberry Pi4.

Hello,

I am not sure whether or not the Border Router image works with the Raspberry Pi 4. I don't have access to one at the moment. Do you? If so, have you tested it?

I'll check with our openthread team, but I have not received any response yet. I'll let you know as soon as I know whether it works, and/or if there are any plans to make an updated image for the RPi4.

Best regards,

Edvin

Hello Edvin,

I downloaded border router prebuilt Raspberry pi image used RaspPi_OT_Border_Router_Demo_v4.1.0-1.alpha.img from Nordic link https://www.nordicsemi.com/Software-and-tools/Software/nRF5-SDK-for-Thread-and-Zigbee/Download#infotabs and it doesn't work on the Raspberry Pi4. 

Did you get any updated from Nordic openthread team to get the Raspberry Pi image for Pi4 board?

EdvinI am also interested in this. I would also like to know what build arguments the Border Router software was created with?

The release notes are incorrect and I found another post indicating the Border Router was based on github commit:

https://github.com/openthread/ot-br-posix/commit/e22d81d3050a8b62bea9f2865c51887ac4c426d4

So I know need to know what build options / command line arguments might be needed to reproduce what was delivered. In my case I want to make some modifications, but in the future I also want to run it on a RaspPi 4.

It looks like it doesn't work, no. I haven't confirmed this, but I suspect that there are no plans on updating the image for RPi 4. This is mostly a developer tool, and not a home automation tool. 

The Border Router Repository is found here:

https://github.com/NordicPlayground/nordic-ot-border-router

But the NFC Daemon tool is not publically available (not our property). This has been requested before in another ticket, but we figured out this is not something we can share. 

I am no expert on building these kind of images, but if you manage to exclude the NFC daemon, you can use this to build the RPi image. 

BR,

Edvin

That github link has no code and was a very old 2017 Nordic project before they released the 'official' Alpha version. It looks like it was replaced with just a README file. I do not care about NFC at all, what I am looking for is a reproducible build of what was delivered. At some point I need to deliver some sort of production quality Border Router to accompany all these Thread devices we are building. You are saying Nordic has no plans to provide this? Nordic claims Thread is certified on the the RaspPi3 but does not provide instructions to reproduce a certified environment?
