Mapping a basic UART project to the HPS_UART pins

Hi, I am currently working working on a project for a class that I am TAing and was asked to add the ability to send and receive data between the DE1-SoC board and a host computer. I have built a ...

If you are not using the HPS, then the problem is most likely that you've selected pins that are dedicated to the HPS so you would need to use the HPS to access the HPS's UART peripheral and that means implementing it in Platform Designer. If you are not going to use the HPS, you'll need to create a UART design in the FPGA fabric and select unused (but accessible on the dev kit) pins to connect it to.

    I see, thank you.
    I am currently using pins dedicated to the hps although the plan is to not use the hps.
    I do not have anything to connect the DE1 board to a pc using the external pins but I have access to a DE2 board. Do you know if the DB9 port goes through hps?
    Cheers
