Adding uart 16550 to the block design

[Luca Frongia]

I am trying to get a webserver running with the esp32, so i am following the https://github.com/Xilinx/embeddedsw/blob/master/ThirdParty/sw_services/lwip213/examples/README.txt tutorial. 

But it uses enables the uart 16550, when i add it to myblockdesign i need to specify the pins. 

Does some know how to fix this?

my version is vivado 2020.2

Set those I/O Standard to LVCMOS33 or whatver fits your design rather than keeping them to DEFAULT to solve the problem. Also you have not assigned FPGA pins to those ports. Hence you have those errors as shown in the screenshot.

 

Read more about the TCL command : set_property IOSTANDARD LVCMOS33 [get_ports <your_port_name>]
