1.2.5. JTAG UART

The USB connection on the Altera Cyclone III Starter Board is used by the Quartus II programmer tool to download the FPGA logic and is also used as a communications port to connect to a PC through the JTAG UART component. The tutorial shows how to use the USB connection for both applications.

The FPGA design must instantiate the JTAG UART component to use the USB connection to communicate with the Cortex-M1 Terminal application. The JTAG UART component is instantiated as the USB_UART in the example SOPC system.
