  The schematic I'm using is "sch-logi-bone-r1_0.PDF" the master UCF file i'm using as reference.

  

• LED0 and LED1 wrong on Early Bird version?

  Hello all,

  
  

  I think LED0 and LED1 are labeled incorrectly on the Kickstarter Early Bird r1.0 board.  

  
  

  I just ran a small "blinky LED" project.  Nothing fancy, just clock and LED:

  
  

  <pre>

  module ledblink(

      input clk,

      output LED

      );

  
  

  reg [23:0] cnt;

  always @(posedge clk) cnt <= cnt + 24'd1;

  assign LED = cnt[23];

  endmodule

  </pre>

  
  

  And my ucf file:

  <pre>

  NET clk LOC = P85;

  NET LED  LOC = P74;

  </pre>

  
  

  Now when I use P140, it blinks LED1, when I use P74, it blinks LED0 even though the schematics and master ucf on github says they are reversed.  Am I missing something here?
