Hello Azure team,

 

We are attepting to put Microsoft Azure Edge v1.2 on an embedded device which does not have any standard package managers like apt, snaps etc.We are using the "Quick start approach with symmetric keys". We copied the relevant binaries

on to the edge device and made all the necessary configuration. Generated the certificates using the tooling scripts and provided the paths in config.toml

We are apble to use openssl s_connect and verify the toolchain. But, azure IoT Edge runtime is not able to communicate with the server.

Below is the logs from "iotedge check --verbose" and "iot runtime". We faced a similar issue when the edged is running. Can you please help us fix the issue?

We currently cannot upgrade to the latest version because of dependency on libc. We first want to test with this version and then consider upgrading.

iotedge check --verbose logs as below:

    Hello @Sharma Rajeev (MS/PAC-PSW3) ,

    welcome to this moderated Azure community forum.

    it seems you do not use a tier 1 supported OS for Azure IoT Edge.

    This does not mean it will not work but you are on your own...

    I suggest opening a support ticket so you can try to get support from Microsoft. This version of the runtime seems not to be supported anymore...

    Or you open an issue on the GitHub repo, supported by the Azure IoT Edge team.

    If the response helped, do "Accept Answer". If it doesn't work, please let us know the progress. All community members with similar issues will benefit by doing so. Your contribution is highly appreciated.
