New ContributorMoving HPS UART to FPGA fabric in Cyclone V
As an update -
I've been able to confirm that in moving the UART and updating the pinmux config file, the UART0USEFPGA flag has been set to 1. The console port (UART0) now outputs data to the PC terminal. However, I'm unable to send characters TO the console.
I've been able to verify that the terminal is sending information to the FPGA but nothing happens. I confirmed that the pin assignments themselves are correct for the FPGA. Could there be something I'm missing from a setup standpoint that allows me to move the console from the origianl HPS UART pins to FPGA pins instead?
Thanks.

ContributorHi,
I'm also working on routing UART to FPGA. I use hps ip and route the uart0 and uart1 to fpga. then I export the uart pins and in fpga connect it's rx/txto my uart core and other pins open or low or high as hps guideline said (https://www.intel.com/content/www/us/en/programmable/documentation/pde1458159073865.html#pde1458166924307). I didn't do anything with pin assignment. But as you said. I'm only receiving hps debug messages from one uart port and receiving nothing from other. Couldn't send to port either. Am I missing something in the connections? How can you connect the uart to fpga? My connections is the attachment. Thx for any help. (ps: I'm using Arria10 device but basics are the same I think)
