Running IoTEdge modules on arm64 architecture

[Shrunoti]

Hi,

I am trying to run modules with IoTEdge on a Nvidia Jetson TX2 hardware with arm64 architecture.

With iotedge v1 by selecting image - azureiotedge-agent:1.0.0-preview022-linux-arm32v7
while setting up iotedgectl I was able to work it out.

I want to setup Iotedge GA with the Jetson (arm64 ). Is there any way to do so?

Hello @Shrunoti

To be clear, we still don't officially support ARM64, but it seems to be running. I have a couple of options for you:

• Build the iotedged for ARM64. We don't yet know what issues you will run into, but how we are building and packaging the iotedged is entirely in this repo.

• Use iotedgectl still. You won't get the security features of the iotedged, but you can still run with the Python scripts. For the GA release, there is a workaround needed (edgeHub cannot start - error:2006D080:BIO routines:BIO_new_file:no such file iot-edge-v1#632 (comment)):

In case you want to use the 1.0 bits with iotedgectl, then you will have to set a couple of environment
variables that are not being set anymore. To do that, set the following in the EdgeHub CreateOptions > during the deployment - {"HostConfig":{"PortBindings":{"8883/tcp":[{"HostPort":"8883"}],"443/tcp":[{"HostPort":"443"}],"5671/tcp":[{"HostPort":"5671"}]}},"Env":["SSL_CERTIFICATE_PATH=/mnt/edgehub","SSL_CERTIFICATE_NAME=edge-hub-server.cert.pfx"]}

This will set environment variables for the path that the EdgeHub should use. In case you have provided your own certificate (Gateway scenario), then use that certificate name instead. We are fixing the Edge runtime so that this should not be needed, but that will not be available till the next release. So this is a workaround till then. Note: This workaround is not needed for 1.0-preview bits.

One thing I have not been able to try (I don't have an ARM64 platform to experiment with) is running the ARM32 bits on an ARM64 device. This is optionally supported is some systems.

Is this enough to start? Need more information?

Hi,
Thank you.
I think I am to going to try re-building iotedged for ARM64. Can you just brief me about how to get going with the rebuilding for specific architecture?

The iotedged executable is built via Rust. You can get it on the native platform, or cross-compile using the "cross" tool.

Clone this repository recursively. (git clone --recursive)
I would recommend installing Rust via rustup.
If you choose to cross-compile, we use the cross tool. If you're lucky - and I'm wishing you all the best - following the Cross instructions, it should "just work".

You should be able to run edgehub and edgeagent "as is" from the containers, but the target platform there is ARM32 as well, and ARM64 is not supported.

Hi @darobs ,

Can we have IoT Edge GA setup with support for ARM32 or ARM64, since we are not able to install the IoT Edge GA itself on ARM64, whereas the preview version is working on the same?

@krunallokhande Closing this issue as it seems stale. Please feel free to re-open in case.
