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 ====> | TTL to RS232 module ====> | Host
I've read the example of the RS232 Max Baurd rate example and the IP guide.
I don't know if the HPS support this example for I DID NOT USE THE NOIS II. Instead I'm using the HPS with HWLIB.
In HWLIB there is a 16550 uart API. Is that related to the RS232 IP?
Is there an example for HPS?
Is it allowed to reach the 921600 baud rate?
thank you for your time
Best Wishes
Alex

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.

Hi
Unfortunately the IP the maximum supported baudrate is up to 115200.
