How can I ugrade my cobos device using TFTP?

The UDS1100 is used as example for upgrading firmware in this article, but this works for all Cobos family devices, including the XPort-05, Micros, xDirect, xPico (NOT xPico WiFi), etc.

TFTP (Trivial File Transfer Protocol) is a file transfer protocol that is part of the Windows, Linux and OS X Operating Systems.

Windows Vista, Windows 7 and Windows 8 don't enable Telnet and TFTP Clients by default. To enable them

  • open Control Panel > Programs and Features
  • click Turn Windows features On or Off in left side
  • enable Telnet Client and TFTP Client then click in OK.

Obtaining Firmware:
You can obtain the most up-to-date firmware and release notes for the unit from the Lantronix web site (https://www.lantronix.com/resources/product-index/) or by using anonymous FTP (ftp://ftp.lantronix.com/pub).

Loading Firmware:
There are several ways to update the unit's internal operational code (*.ROM):

  • using DeviceInstaller (the preferred way)
  • using TFTP, or
  • using the serial port.

You can also update the unit's internal Web interface (*.COB) using TFTP or DeviceInstaller. Check the Lantronix web site for the latest versions and release notes.

Using TFTP: Command Line Interface:
To load firmware into a CoBos device from a network host's command line enter the following from a TFTP command line interface:

> tftp -i <ip address> put <local filename> <destination file name>

The following examples demonstrate the TFTP command sequence to download the .rom file and the .cob file:

> tftp -i 192.168.1.111 put uds1100_6802.rom U3
> tftp -i 192.168.1.111 put uds1100_webm_1901.cob WEB1

The example above uses typical source and destination file names. The source file names you download will differ depending on the CoBos device and firmware/web manager version. The destination file name for the .rom file will differ by product. You can find the destination file name for your CoBos device server in the Firmware Upgrades chapter of its User Guide.

The .cob file should be loaded into the WEB1 partition.
