What is the difference between JTAG uart and the uart (RS-232) serial ?

I know the use of UART RS 232 for transmitting serial data, but JTAG ? and I can see most of designs are using JTAG on Qsys not RS-232 . thanks in advance

Hi,

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.

Refer Embedded Peripherals IP User Guide and link.
