It's been a few years since my last FPGA project, so I was a bit rusty. What I benefited from most was looking at that posted source ex... Tom Riddle

Can you link to the post? It may help me update the wiki page. Jonathan Cormier

Hi Jonathan, thanks for the info... So I followed an example from a post a few years back (FPGA GPIO: toggle problem) and was able to get the GPIO going.

The fpga can connect the gpio core to any pin you want. Gpio 144 should map to the first gpio core pin in the fpga image.
The .ucf file is used to map processor pins to net names in the vhdl.

Hi,
I am attempting to get some FPGA GPIO control going with an L138/LX45 IndustrialIO board. Have been following these instructions
