Design and Verification of a SPI to JTAG Interface Adapter


Goal and Motivation:

Almost all hardware devices have JTAG connections which can provide data from registers or provide low level control of pins via a boundary scan chain. Unfortunately, most microcontrollers do not have libraries or drivers for communicating using the JTAG protocol. The goal of this project is to provide a way to allow users to use existing libraries to access data that is typically accessed via JTAG protocol.
