下载适用于的 IDT FreeRTOS

本主题介绍了下载适用于的 IDT FreeRTOS 的选项。您可以使用以下软件下载链接之一,也可以按照说明以编程方式下载 IDT。

下载此软件即表示您同意Amazon IoT Device Tester许可协议.

注意

IDT 不支持由多个用户从共享位置(如 NFS 目录或 Windows 网络共享文件夹)运行。建议您将 IDT 包解压缩到本地驱动器,并在本地工作站上运行 IDT 二进制文件。

手动下载 IDT

本主题列出了支持的适用于的 IDT FreeRTOS 版本。作为最佳实践,我们建议您使用最新版本的Amazon IoT Device Tester它支持你的目标版本的 FreeRTOS。新版本的 FreeRTOS 可能要求您下载新版本的Amazon IoT Device Tester. 如果您开始测试运行,则您会收到通知Amazon IoT Device Tester与您使用的 FreeRTOS 版本不兼容。

请参阅 支持的版本Amazon IoT Device Tester适用于 FreeRTOS

以编程方式下载 IDT

IDT 提供了一个 API 操作,您可以使用该操作来检索可以通过编程方式下载 IDT 的 URL。您还可以使用此 API 操作来检查您是否拥有最新版本的 IDT。此 API 操作具有以下终端节点。

https://download.devicetester.iotdevicesecosystem.amazonaws.com/latestidt

要调用此 API 操作,您必须具有执行iot-device-tester:LatestIdtaction. 包括你的Amazon有符号iot-device-tester作为服务名称

API 请求

HostOs— 主机的操作系统。从以下选项中进行选择:
  • mac

  • linux

  • windows

TestSuite类型 — 测试套件的类型。选择以下选项:

FR— 适用于的 IDT FreeRTOS

ProductVersion

(可选)FreeRTOS 的版本。该服务返回该版本的 FreeRTOS 的最新兼容版本的 IDT。如果未指定此选项,则该服务将返回最新版本的 IDT。

API 响应

API 响应采用以下格式。这些区域有:DownloadURL包括一个 zip 文件。

{ "Success": True or False, "Message": Message, "LatestBk": { "Version": The version of the IDT binary, "TestSuiteVersion": The version of the test suite, "DownloadURL": The URL to download the IDT Bundle, valid for one hour } }

示例

您可以参考以下示例以编程方式下载 IDT。这些示例使用您存储在中的凭证AWS_ACCESS_KEY_IDAWS_SECRET_ACCESS_KEY环境变量。要遵循最佳安全实践,请不要将凭据存储在代码中。

例如:使用 cURL 7.75.0 或更高版本(Mac 和 Linux)下载

如果您使 cURL 版本 7.75.0 或更高版本,则可使用aws-sigv4标记以签署 API 请求。此示例使用jq以解析响应中的下载 URL。

  • Replaceus-west-2与您的Amazon Web Services 区域. 有关区域代码的列表,请参阅区域终端节点.

  • Replacelinux使用主机的操作系统。

  • Replace202107.00使用你的 FreeRTOS 版本。

url=$(curl --request GET "https://download.devicetester.iotdevicesecosystem.amazonaws.com/latestidt?HostOs=linux&TestSuiteType=FR&ProductVersion=202107.00" \ --user $AWS_ACCESS_KEY_ID:$AWS_SECRET_ACCESS_KEY \ --aws-sigv4 "aws:amz:us-west-2:iot-device-tester" \ | jq -r '.LatestBk["DownloadURL"]') curl $url --output devicetester.zip

例如:使用早期版本的 cURL(Mac 和 Linux)下载

您可以将 cURL 下命令与Amazon你签署和计算的签名。有关如何签名和计算的详细信息Amazon请参阅签名签名AmazonAPI 请求.

  • Replacelinux使用主机的操作系统。

  • Replace时间戳随着日期和时间,例如20220210T004606Z.

  • Replace日期随着日期,例如20220210.

  • ReplaceAWSRegion与您的Amazon Web Services 区域. 有关区域代码的列表,请参阅区域终端节点.

  • ReplaceAWSSignature使用Amazon签名你生成的。

curl --location --request GET 'https://download.devicetester.iotdevicesecosystem.amazonaws.com/latestidt?HostOs=linux&TestSuiteType=FR' \ --header 'X-Amz-Date: Timestamp \ --header 'Authorization: AWS4-HMAC-SHA256 Credential=$AWS_ACCESS_KEY_ID/Date/AWSRegion/iot-device-tester/aws4_request, SignedHeaders=host;x-amz-date, Signature=AWSSignature'

例如:使用 Python 脚本下载

此示例使用 Python请求库. 此示例从 Python 示例改编为登录AmazonAPI 请求中的Amazon一般参考.

  • Replaceus-west-2与您的区域有关。有关区域代码的列表,请参阅区域终端节点.

  • Replacelinux使用主机的操作系统。
