Greengrass IDT support for IDT and AWS Qualified Device

You're correct that there is currently a limitation with AWS IoT Device Tester (IDT) for AWS IoT Greengrass V2 regarding ARM architectures. As of now, IDT for Greengrass V2 only supports x86-64 architecture for Linux systems and does not have native support for ARM-based systems like aarch64.

However, this doesn't mean that ARM-based devices cannot be qualified for AWS IoT Greengrass. The qualification process and the actual device architecture are indeed two separate concepts.

To qualify an ARM-based device for AWS IoT Greengrass, you would typically need to run the IDT on a supported system (x86-64 Linux, macOS, or Windows) that is connected to your ARM-based device under test. The IDT runs on the host computer and performs tests on the connected device, regardless of its architecture.

The qualification process involves running a series of tests to ensure that the device meets the requirements for running AWS IoT Greengrass Core software and can communicate properly with AWS Cloud services. These tests check for core dependencies, deployment capabilities, MQTT functionality, and other features depending on the specific qualification you're seeking.

For devices with ARM architecture, you would still need to ensure that your device meets all the software and hardware requirements for AWS IoT Greengrass, including having the correct version of Java installed and meeting other dependencies.

It's worth noting that there are both required and optional test groups in the qualification process. The required tests ensure basic compatibility, while optional tests can qualify your device for additional capabilities in the AWS Partner Device Catalog.

If you're having difficulty with the qualification process due to the architecture mismatch, it would be advisable to contact AWS support or consult with an AWS partner who has experience in qualifying ARM-based devices. They may be able to provide guidance on alternative methods or workarounds to complete the qualification process for your ARM-based device.
