Hello, nice people. I'm working on a project that will require the use of the AXI UART16550 IP. Right now, I'd want to change the baud rate of the IP, but I'm having problems doing so. There is an example in the IP's product guide that shows me how to design using the core (see image). Even this section is challenging for me because of my lack of C understanding... I've also included a picture of the block design that connects the PS to the IP (see image).

I'm hoping that some of you may be able to assist me in carrying out this example.

Hi,
because of my lack of C understanding
I can see nothing related to C.

For baudrate setting the solution is straight forward.
* Use the given formula, treat it as 16 bit (2x 8 bit) unsigned integer.
* send the LOWer and HIGHer byte

What exactly is the probem?

Hello there, Klaus. The primary issue is that the example shows the stages, but I am unable to complete this job in Vitis since I don't know where to begin. Specifically, I am not yet proficient in the design flow.
