Overview; Hardware And Software Requirements; Jtag Programming Hardware Checklist - Lantronix xPico 200 Series Manual

Overview

This Application Note is designed to help Lantronix xPico 200 Series users perform JTAG-based
firmware programming of the modules. When customers design the xPico 200 series modules
into their products without exposing the UART pins for typical firmware programming methods,
the JTAG interface will be the only way to program or update the device firmware.

Hardware and Software Requirements

The JTAG Programming Hardware Checklist below contains the hardware required to perform
JTAG programming of the xPico 200 series modules. This application note uses Olimex and Tag-
Connect hardware and adapters. There are numerous JTAG programmers available – other
brands and adapter types may also work.
Note: The hardware adapters and tools are not provided by Lantronix and should be purchased
from an electronics supply business or the manufacturer of the hardware.
The software needed to accomplish JTAG programming (xPico200Recovery.zip) is supplied
by the Lantronix support team or Field Applications Engineer.
