Zybo Z7-10 USB UART RX Connection

Question

Hello,

I am trying to send a very small amount of information (8-bit numbers) from my PC to my Zybo Z7-10 over a USB connection using UART. I understand that the best way to do this is using the block diagram and then the SDK, however I can't find any tutorials or walkthroughs that use USB, not HDMI or Ethernet. I know it is possible to use the on-board USB connection, though. Is there a tutorial that I have missed? What is the best way to go about doing this? The hello world, etc. tutorials don't show how to actually make that UART connection, just how to deploy to a board over USB. 

Thanks in advance for your help!

Hi @oqas,

There is no connection needed in block diagram in order to use UART. The USB-UART bridge is connected to PS. You will find some Xilinx examples following this path: C:\Xilinx\SDK\2019.1\data\embeddedsw\XilinxProcessorIPLib\drivers\uartps_v3_7
