I have a Lattice Brevia XP2 Kit (the older one that came out in 2010/2011, and the not the newer version 2). The only PC connectivity it has is through serial (rs232). I have anetbook that does not have the rs232 port, but I regularly use a Sanguino via virtual COM port over USB. I use a FTDI breakout board for this.
I am trying to use this FTDI board to also communciate with the XP2 kit. For this, I have wired the rs232 null modem cable supplied in the XP2 kit to the FTDI board via temporary connections using jumper cables. Here is a pic (apologies for the quality) and the wiring diagram is below it.
RS232 pin assignments on the XP2 Brevia kit:
When I analyze this using the Advanced Serial Port Monitor utility, I see no errors and can send data without errors. I am supposed to see some headers from the Brevia XP2 board but I see nothing (no errors too).
What am I doing wrong?
