TommyT Posted February 8, 2015 Report Share Posted February 8, 2015 I just got a PapilioPro with LogicStartMega Wing (ISE WebPack 14.7 and Papilio Loader 2.6 used). My first Bit-File ( first example from 'IntroToSpartanFPGABook') was correctly generated by ISE.Options: Family:Spartan 6; Device:XC6SLX9 Package:TQG144; Speed -3 library IEEE;use IEEE.STD_LOGIC_1164.ALL;entity switches_LEDs is Port ( switch_0 : in STD_LOGIC; switch_1 : in STD_LOGIC; LED_0 : out STD_LOGIC; LED_1 : out STD_LOGIC);end switches_LEDs;architecture Behavioral of switches_LEDs isbegin LED_0 <= switch_0; LED_1 <= switch_1;end Behavioral; constraints (copied from the above book)# Constraints for Papilio OneNET switch_1 LOC = "P3" | IOSTANDARD=LVTTL;NET switch_0 LOC = "P4" | IOSTANDARD=LVTTL;NET LED_1 LOC = "P16" | IOSTANDARD=LVTTL;NET LED_0 LOC = "P17" | IOSTANDARD=LVTTL; When connecting the Board with Wing to my PC, LEDs 0,2,4 and 6 are flashing.Transferring the Bit-File with Papilio Loader:JTAG chainpos: 0 Device IDCODE = 0x24001093 Desc: XC6SLX9Using devlist.txtCreated from NCD file: switches_LEDs.ncd;UserID=0xFFFFFFFFTarget device: 6slx9tqg144Created: 2015/02/08 16:15:19Bitstream length: 2724832 bitsUploading "C:\Users\Tomuser\Documents\FPGA\switches_LEDs\switches_leds.bit".

Can you give me a hint how to go further?(Are the constraints, which were planned for Papilio One) correct ? Thanks! Link to comment Share on other sites More sharing options...
Jack Gassett Posted February 8, 2015 Report Share Posted February 8, 2015 Hello TommyT, It looks like your constraints are not in the correct pin locations. Please take a look at this chart in the Hardware Guide to see the correct pins for the Papilio Pro:http://www.papilio.cc/index.php?n=Papilio.LogicStartMegaWing#led switch_0 should be "P114" for the Papilio Pro and so forth.

james1095 Posted February 9, 2015 Report Share Posted February 9, 2015 I like to start with the generic constraints file, you just change the net names on the pins you want to use, then delete or comment out all the other lines. Constraints files for the Papilio One and Pro are here: http://forum.gadgetfactory.net/index.php?/files/file/27-logicstart-megawing-papilio-propapilio-one/ Link to comment Share on other sites More sharing options...
