Can't communicate to Virtex5 TXT via UART

 

Hi,

 

I'm testing my Virtex-5 TXT (NetFPGA10G) for verify that everything on the board is working properly

by following Production test on Github.

 

Here is a result from testing...

  I encountered a problem with UART communication. It seems like the system can't communicate to a board.

  I've checked my RS232 cable and its working fine. 

 

  Also the result from RLDRAM test via serial monitor is unexpected data.

The correct one is

Then I connected RS232 cable with my laptop and use serial monitor in Arduino IDE to see what data was sent by FPGA board.

Using serial terminal emulation in the hostPC (which FPGA located) to communicate which is Minicom, Picocom and Putty gave the same result.

 

Anyway to solve the problem ? 

Thanks in advanced.
