Ts7300 Fpga Uart Problem
Hi,
I am using com3(TS7300)port with modem and in the same manner using other board with modem and by ATDT dialing the modem and once two board are connected using buad rate 115200bits/sec then using keyboard sending data from one board to other but data is not receving on the Board but instead of using 2 board,when I connected BOARD with PC(LINUX)using modem then transmitting data from Board its coming on TERMINAL of PC.But when I transmitting data from PC nothing is coming on board,its means that board is not receiving data only transmitting the data through COM3,I am stuck up at this problem.PLS Guide me. THANX.... |
Have you verified the wires on the cable that connects to COM 3 on bad board good?
If so have you tried this test with another COM port on the board? |
Hi,
I have checked with other com(4,5,6) of board same problem is coming.When I am Transmiting the data from Board tx Data LED(on board) is blinking and When I am Transmiting the data from external device i.e. PC via minicom no data is receiving on board(rx Data led is not blinking) its means only data is Transmiting from FPGA port not receiving at COM port.Why this problem is coming I am not getting. PLS guide me from coming out this problem. Thanx. |
Did you make sure the wiring for the RX signal is good?

Now I am facing another problem.
I have connected two embedded board(TS 7300) using two modems.One is DFM-562E++ and other is DFM-560ES. both are 56k modems.Later one is transmitting & receiving both but the first one is able to only receive but not transmitting. So can u suggest some possible solution to this problem. |
