7i80db connect to 7i76x2 and 7i74

Dear all,
I'm currently working on implementing LinuxCNC on the following setup: one MESA 7i80db-16 FPGA board, that is connected to 2 MESA 7i76 boards and a MESA 7i74 for 4 SSI encoders. Do you know which .bit file should I flash on the FPGA for this specific configuration?

Might have to wait for PCW or make the firmware yourself ( it is open source ).
I had a similar setup for 5i25/7i77/7i74 with 6 SSI encoders, been running daily for over 4 years.

Hi, I am newbie. How do I make the firmware?
I'm downloading the Xilinx_ISE_14.7. It's very large

thanks

Ok thank you very much..
Can i use port 4 for INPUT/OUTPUT IO control?

Yes, its just GPIO

I included the new pinout file so you can take a look at the layout
(or modify it)
