The JTAG UART core uses the JTAG circuitry built into Intel FPGAs and provides host access via the JTAG pins on the FPGA. The host PC can connect to the FPGA via any Intel FPGA JTAG download cable.
The JTAG UART core eliminates the need for a separate RS-232 serial connection to a host PC for a character I/O.
If your hardware supports RS232, You can use UART RS 232.
okay, does this means that USB-blaster and JTAG UART are two cores that allows a host computer to access the FPGA kit ?
because on my FPGA kit I have USB-blaster and JTAG UART pins, are they both work for hosting a computer ?
when I want to connect my kit to the computer and I want to use Qsys, should the JTAG UART core be added to the embedded system, Although I am using usb blaster and when I use Qsys and build an embedded system, and download it to the board , I do not add any UART interface with the Embedded system created in Qsys. Is this normal ?
