<a name="elgsg-setup-ota-update-create"></a>

1. Open the [AWS IoT console](https://console.aws.amazon.com//iot/home). Choose **Manage** then choose **Jobs**. Choose **Create job**, **Create FreeRTOS OTA Update Job**, then choose **Next**. 

1. Enter a job name which is unique within your AWS account. Enter an optional description. Choose **Next**. 

1. From the **Devices to update** dropdown, choose the thing name associated with your ExpressLink module when it was registered with the account. Choose **MQTT** as the protocol that will be used to perform the transfer, and unselect **HTTP** if it is selected.

1. Choose **Use my custom signed file**; this will display a form to be filled in. Use the details from [Prerequisites](elgsg-setup-ota-update-prereqs.md) to fill in the form. 

1. In the **signature** field, enter the base64 encoded signature for the image. From the **Original hashing algorithm** drop down, select the hashing algorithm provided by the manufacturer. From the **Original encryption algorithm** drop down, select the encryption algorithm provided by the manufacturer. In the **Path name of code signing certificate on device**, enter the path name, if any is provided by the manufacturer. (If the path name is not provided, then you can just enter 'NA'.)

1. Choose **Upload a new file**, then **Choose file** and upload the image you received from the manufacturer. Choose **Create S3 bucket** for the new uploaded image and proceed with creating a new bucket. If needed, you can also choose an existing bucket in your account by selecting **Browse S3** option.

1. Under **Path Name of file on device** you can enter 'NA' if the image is not targeted as an executable file within a filesystem.

1. From the **File type** drop down select a value (default is 0) to signify this is an ExpressLink firmware update as opposed to a host firmware update.

1. From the **role** dropdown under the **IAM role** section, select the OTA update role you created above. Choose **Next**.

1. Choose **Create Job**. If the job creation was successful, it should list the job name and state as 'in progress'.
