.Net Core Managed Gateway on Raspberry Pi

[malichishti]

Hi,

I have created a .Net Core Console application with a manged Gateway inside it, using this nuget

I use Microsoft.Azure.Devices.Gateway.GatewayInterop to create the gateway, this works fine on a Windows machine but when i build and publish it for linux-arm and deploy it on Raspberry Pi it gives me following error[please note all the other .net core code works fine]:

The code looks like below:

PublishOutput.zip is the zip file containing all the files in the Published output.

Can you advise on what is that i'm doing wrong?

Thank you,
Ali

Hi Ali, From the error it seems like some of the dependencies on the gateway is missing. Make sure you copy all the dlls needed. Look also for the native dependencies, not just the managed. Let me know, Angelo Ribeiro

@aribeironovaes thank you for your reply. I have copied all the files that were there in the publish output folder. I also attached it above, you can see that it contains dotnetcore.dll as well.
Since the nuget package already has native dependencies i assume they are being published - do you know how i can confirm it?

HI Ali,

Unfortunately, by looking into your zip folder, I didn't find anything missing.

Usually what I do is to run dependency walker (or similar) software to list all dependencies and than I start checking 1:1.

Another approach you can take is filing an issue here: https://github.com/Azure-Samples/iot-edge-samples.

This is the github for the team that owns the nuget package and samples for iot_edge. So, I would start trying to put their sample to run on a Raspberry Pi and from there you start introducing your changes.

Sorry I couldn't help more, I will also try around here who lately have run this in a raspberry pi.

Question, were you able to run our edge (native) version on the raspberry pi?

Angelo Ribeiro.

Hi @aribeironovaes

I have logged it here

I haven't been able to run it on Raspberry Pi as the instructions here were for Ubuntu while Raspberry is Debian.

I did try to copy above runtime files from microsoft.azure.devices.gateway.native.debian.x64 nuget package to Pi and run ./gw but i got following error:

bash: ./gw: cannot execute binary file: Exec format error

X64 (short for x86-64 bit) is NOT meant for Raspberry Pi, which has an ARM64 processor.

Depending on your Linux distribution you would need ARM64 or ARM32 packages. If you would use Windows IoT Core then i think you would always need ARM32 packages since there is no public 64bit version of Windows IoT Core yet.

[aribeironovaes]

Exactly. You have to get arm bits.

Are ARM32 packages publicly available?

[aribeironovaes]

I'm not sure about that, but you can try to build yourself on the raspberry pi. Last person here that make that to work was David. Give it a try, follow the instructions on how to build for Raspberry Pi and try to use that. Thanks, Angelo Ribeiro.

@aribeironovaes which instructions are you referring to?

I haven't had any luck in getting a reply from https://github.com/Azure-Samples/iot-edge-samples

[aribeironovaes]

Nops, Edge samples are samples that uses the packages (which I don't believe we have for ARM). I would have to search, but I believe we had some documentation that teaches how to build for Raspberry Pi. (ARM). BTW, I don't know if you see the announcement, but you can move to our v2, which uses docker container and we have samples based on .NET Core. Just as an alternative. I'm sure that runs in a raspberry Pi. Thanks, Angelo Ribeiro.

The problem was iot-edge does not work on Raspian Stretch; it needs openssl 1.0.0 which is not available. I moved to Raspian Jessie and added the run-times to /usr/lib/ and it worked.

Thank you
