# Setup the 1.0 qualification prerequisites
This section describes the prerequisites for testing microcontrollers with AWS IoT Device Tester.
## Download FreeRTOS
You can download a release of FreeRTOS from [GitHub](https://github.com/aws/amazon-freertos) with the following command:
```
git clone --branch --recurse-submodules https://github.com/aws/amazon-freertos.git
cd amazon-freertos
git submodule update --checkout --init --recursive
```
where is a version of FreeRTOS (for example, 202007.00) corresponding to an IDT version listed in [Supported versions of AWS IoT Device Tester](dev-test-versions-afr.md). This ensures you have the full source code, including submodules, and are using the correct version of IDT for your version of FreeRTOS, and vice versa.
Windows has a path length limitation of 260 characters. The path structure of FreeRTOS is many levels deep, so if you are using Windows, keep your file paths under the 260-character limit. For example, clone FreeRTOS to `C:\FreeRTOS` rather than `C:\Users\username\programs\projects\myproj\FreeRTOS\`.
### FreeRTOS qualification with LTS libraries
+ In order for your microcontroller to be designated as supporting long-term support (LTS) based versions of FreeRTOS in the AWS Partner Device Catalog, you must provide a manifest file. For more information, see the [ FreeRTOS Qualification Checklist](https://docs.aws.amazon.com/freertos/latest/qualificationguide/afq-checklist.html) in the *FreeRTOS Qualification Guide*.
+ In order to validate that your microcontroller supports LTS based versions of FreeRTOS and qualify it for submission to the AWS Partner Device Catalog, you must use AWS IoT Device Tester (IDT) with FreeRTOS Qualification (FRQ) test suite version v1.4.x.
+ Support for LTS based versions of FreeRTOS is limited to the 202012.xx version of FreeRTOS.
## Download IDT for FreeRTOS
Every version of FreeRTOS has a corresponding version of IDT for FreeRTOS to perform qualification tests. Download the appropriate version of IDT for FreeRTOS from [Supported versions of AWS IoT Device Tester](dev-test-versions-afr.md).
Extract IDT for FreeRTOS to a location on the file system where you have read and write permissions. Because Microsoft Windows has a character limit for the path length, extract IDT for FreeRTOS into a root directory such as `C:\` or `D:\`.
**Note**
We don't recommend that multiple users run IDT from a shared location, such as an NFS directory or a Windows network shared folder. This may result in crashes or data corruption. We recommend that you extract the IDT package to a local drive.
## Create and configure an AWS account
### Sign up for an AWS account
If you do not have an AWS account, complete the following steps to create one.
**To sign up for an AWS account**
1. Open [https://portal.aws.amazon.com/billing/signup](https://portal.aws.amazon.com/billing/signup).
1. Follow the online instructions.
Part of the sign-up procedure involves receiving a phone call or text message and entering a verification code on the phone keypad.
When you sign up for an AWS account, an *AWS account root user* is created. The root user has access to all AWS services and resources in the account. As a security best practice, assign administrative access to a user, and use only the root user to perform [tasks that require root user access](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_root-user.html#root-user-tasks).
AWS sends you a confirmation email after the sign-up process is complete. At any time, you can view your current account activity and manage your account by going to [https://aws.amazon.com/](https://aws.amazon.com/) and choosing **My Account**.
### Create a user with administrative access
After you sign up for an AWS account, secure your AWS account root user, enable AWS IAM Identity Center, and create an administrative user so that you don't use the root user for everyday tasks.
**Secure your AWS account root user**
1. Sign in to the [AWS Management Console](https://console.aws.amazon.com/) as the account owner by choosing **Root user** and entering your AWS account email address. On the next page, enter your password.
For help signing in by using root user, see [Signing in as the root user](https://docs.aws.amazon.com/signin/latest/userguide/console-sign-in-tutorials.html#introduction-to-root-user-sign-in-tutorial) in the *AWS Sign-In User Guide*.
1. Turn on multi-factor authentication (MFA) for your root user.
For instructions, see [Enable a virtual MFA device for your AWS account root user (console)](https://docs.aws.amazon.com/IAM/latest/UserGuide/enable-virt-mfa-for-root.html) in the *IAM User Guide*.
**Create a user with administrative access**
1. Enable IAM Identity Center.
For instructions, see [Enabling AWS IAM Identity Center](https://docs.aws.amazon.com//singlesignon/latest/userguide/get-set-up-for-idc.html) in the *AWS IAM Identity Center User Guide*.
1. In IAM Identity Center, grant administrative access to a user.
For a tutorial about using the IAM Identity Center directory as your identity source, see [ Configure user access with the default IAM Identity Center directory](https://docs.aws.amazon.com//singlesignon/latest/userguide/quick-start-default-idc.html) in the *AWS IAM Identity Center User Guide*.
**Sign in as the user with administrative access**
+ To sign in with your IAM Identity Center user, use the sign-in URL that was sent to your email address when you created the IAM Identity Center user.
For help signing in using an IAM Identity Center user, see [Signing in to the AWS access portal](https://docs.aws.amazon.com/signin/latest/userguide/iam-id-center-sign-in-tutorial.html) in the *AWS Sign-In User Guide*.
**Assign access to additional users**
1. In IAM Identity Center, create a permission set that follows the best practice of applying least-privilege permissions.
For instructions, see [ Create a permission set](https://docs.aws.amazon.com//singlesignon/latest/userguide/get-started-create-a-permission-set.html) in the *AWS IAM Identity Center User Guide*.
1. Assign users to a group, and then assign single sign-on access to the group.
For instructions, see [ Add groups](https://docs.aws.amazon.com//singlesignon/latest/userguide/addgroups.html) in the *AWS IAM Identity Center User Guide*.
## AWS IoT Device Tester managed policy
The `AWSIoTDeviceTesterForFreeRTOSFullAccess` managed policy contains the following AWS IoT Device Tester permissions for version checking, auto update features, and collection of metrics.
+ `iot-device-tester:SupportedVersion`
Grants AWS IoT Device Tester permission to fetch the list of supported products, test suites and IDT versions.
+ `iot-device-tester:LatestIdt`
Grants AWS IoT Device Tester permission to fetch the latest IDT version available for download.
+ `iot-device-tester:CheckVersion`
Grants AWS IoT Device Tester permission to check version compatibility for IDT, test suites and products.
+ `iot-device-tester:DownloadTestSuite`
Grants AWS IoT Device Tester permission to download test suite updates.
+ `iot-device-tester:SendMetrics`
Grants AWS permission to collect metrics about AWS IoT Device Tester internal usage.
## (Optional) Install the AWS Command Line Interface
You might prefer to use the AWS CLI to perform some operations. If you don't have the AWS CLI installed, follow the instructions at [Install the AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/installing.html).
Configure the AWS CLI for the AWS Region you want to use by running **aws configure** from a command line. For information about the AWS Regions that support IDT for FreeRTOS, see [AWS Regions and Endpoints](https://docs.aws.amazon.com/general/latest/gr/rande.html#amazon-freertos-ota-control). For more information about **aws configure** see [ Quick configuration with **aws configure**](https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html#cli-configure-quickstart-config).
