i'am still trying send "Hello World" to my terminal. I made a simple design in vivado and use the uartlite ip. But i cant generate the Bitstream because of undefined ports:
"[DRC NSTD-1] Unspecified I/O Standard: 2 out of 132 logical ports use I/O standard (IOSTANDARD) value 'DEFAULT', instead of a user assigned specific value. This may cause I/O contention or incompatibility with the board power or connectivity affecting performance, signal integrity or in extreme cases cause damage to the device or the components to which it is connected. To correct this violation, specify all I/O standards. This design will fail to generate a bitstream unless all logical ports have a user specified I/O standard value defined. To allow bitstream creation with unspecified I/O standard values (not recommended), use this command: set_property SEVERITY {Warning} [get_drc_checks NSTD-1]. NOTE: When using the Vivado Runs infrastructure (e.g. launch_runs Tcl command), add this command to a .tcl file and add that file as a pre-hook for write_bitstream step for the implementation run. Problem ports: uart_rtl_rxd, and uart_rtl_txd."
So i tried to solve that issue, but i dont know which pins i should connect with the used ports. I thought, that i should read the manual, but the manuel gives me no answer!
The page where J14 (USB-UART-Bridge) should be decribed is lost - maybe in the deep space or in an black hole?
Where is the schematic for the Arty-Z7-20 board? I dont mean the one, where J14 is gone away.

My trust in you is nearly gone...
Thank you...
