Cyclone IV can't recieve data trough second UART

I had no luck. I made another module called uartrx2 as you suggested, initialized pin 100 for uart1 and pin 84 for uart2. Check .qsf file to are they properly assigned, and they are, but still uart2 wont work. So I changed pins to see if pin 84 works, I assigned pin 84 to uart1 and pin 100 to uart2, and uart1 works, uart2 does not work. To check if my second nodeMCU is sending data I connected it to uart1 pin and it does work.

I have no clue why is that happening because both grounds are connected, I used pins that have DIFFIO function, but for some reason second uart used in code does not work.

Here is link to my code: https://github.com/lejlahusi/FPGA.git

Thank you so much for the effort.
