RPI 7C81 + 7i76 + 7i73

Hello to everyone,

I have a Problem in my configuration - i cant use the P5 or P6 connector from the 7C81 to drive the 7i73.

I use the following Bitfile: 7C81_7i76x2d.bit

I think there is just  sserial bus at the P1 - P3 Connectors

can somebody change the bitfile that i have one sserial at P5 ?

thanks bassti

Bitfile i use :

As tommylight says, you can use the interface on the 7I76,
alternatively if you only have one 7I76, you can use this firmware:

 

It works,

thank you
