About JTAG uart time serials /chronogenesis ?

i wanna translate files from a embeded platform to FPGA via its JTAG_uart module; then there is a program that read data from jtag_uart device/file on the FPGA , so the problem is how to program...

i want to program epcs via jtag,i have a microcontroller(LPC),a FPGA(EPCS IV),EPCS64;now my solution :

1) Configure the FPGA via Jrunner (use .rbf that contains nios os and a onchipmemory.hex that read data from jtag_uart and write epcs_controller )

2)transe data to the FPGA via JTAG_uart(nios running ,jtag changed jtag_uart)

now my problem is that how to transe data to the jtag_uart, and the chronogenesis of the jtag _uart?
