Is it possible to connect DSTREAM-ST to FPGA board

Hi,

I am new to ARM. Currently I have an RTL for ARM which has 4 IO ports (rst, data1, data2, clk) driven as GPIOs on the FPGA board. I want to use the debugger tool from the ARM. This debugger GUI sends data through JTAG port of DSTREAM-ST hardware to ARM processor.

1. Is this DSTREAM-ST can be driven only by connecting the above 4 lines on the JTAG connector?
2. Or can I use the User IO port available on this device to connect those 4 lines to GUI?
3. If I use User IO port, does the GUI support data transfer between FPGA and PC?
4. What other care/considerations should be taken to use the GUI to transfer the data between PC and FPGA?

Earliest response helps me a lot. Thanks in advance.

Regards
