  1. Hi Dan, Thanks for the references and the tips. I used the Cmod A7 GPIO Demo project. I somehow skipped this tutorial earlier but it's what I was looking for.
  2. Hi, Has anyone tried using the CMOD-A7's USB to UART converter without Microblaze? I was able to see CMOD-A7 transmit to terminal using the "CMOD A7 Getting Started with Microblaze" tutorial. I want to do the same without using Microblaze. I tried driving the FPGA's assigned uart tx pin, using a previously working UART RTL, but the LED near USB connector does not even light up. Are there some other steps required or guidelines? Thanks! SFD
