Using Uart IP with HPS(Cyclone V soc dev board)

Hi I'm using HPS and want to use the UART IP to create a FPGA module to make a connection between the host and the board. Here is the system HPS : Buffer ====> | FPGA: Uart module ====> | ...

Hi Alex


The difference between the UART Core IP and the 16550 UART IP is that the UART Core is just the basic RS232 functionality where as the 16550 UART consist of FIFO Buffer incorporated.


However for your usage, the HPS has its own UART peripheral and do not need to use the FPGA IP.

In the HPS you could enable the UART and route the UART pins to the FPGA.

    Hi,

    I've read the API for the 16550 UART port, is there some ways to change the baud rate to 921600? For the fastest speed for the API is 115200.

    Thank you.
