Command Line: Upgrading the MicroRAPTOR using SFTP

This section will document how to upgrade the firmware on the MicroRAPTOR. This process takes approximately 5 minutes to execute.

To perform the tasks in this section, you will have already logged into the MicroRAPTOR via an SSH connection or through the console port. For all upgrades it is recommended that user’s backup their current running configuration prior to commencing the upgrade process.

A SFTP server must be installed on a device with network connectivity to the MicroRAPTOR. There are a number of commercial and free SFTP server options available. For this example the Rebex Tiny SFTP Server was used as the server. It may be downloaded from this site: https://www.rebex.net/tiny-sftp-server/

Valid Upgrade Paths

If the release that your device is running is not listed in the Supported Upgrade Paths table, it is recommended that the support team is contacted for more detailed instructions.

  1. Install the SFTP server on a machine that has network connectivity to the MicroRAPTOR.
  2. Configure the SFTP server such that its base directory contains the firmware file you wish to upload. Depending on the server software you are using there may be more settings that need to be configured. The Rebex SFTP server uses a configuration file, RebexTinySftpServer.exe.config, which the user must modify. Please note that the free Rebex is not full featured and the professional option may be more suitable for a commercial deployment. The link is here: https://www.rebex.net/tiny-sftp-server/
