Hello, I am a beginner working with RFSoC 4x2 boards for the first time. I have an assignment in the lab, and my first task is to target an ADC tile directly to the board, apply a signal through a signal generator, and measure it with an oscilloscope. I’m having trouble utilizing Vivado BD for an easy approach. I don’t know how to set up the connection in RFDC, I want to apply an external signal, how can I do that? I am also attaching a picture of the Block Design.
Hi @khr2664,
It seems you already applied external signals to your RFDC. The issues in your BD, your clocks and AXI4-Stream outputs, which I cannot determine without your RFDC settings. If you want to do a feedback loop, I would recommend checking out the RFSoC-PYNQ repo. For feedback loop, you also need DAC connections.
I wouldn’t recommend using ADC Tile 224 as they made an error for connections (check out schematic and manual from Real Digital Website RFSoC 4x2). In RFSoC 4x2, most connections are predetermined, so, I believe you won’t need to make changes on constraint file.
Hope this helps.
Hi @mtsanic,

Can you elaborate on the error?
@cathalmccabe showed the error on No MTS on RFSoC4x2 post. It is a simple connection error, where positive and negative ports are mistaken. I also confirmed this with schematics and my own design. It is a little unfortunate.
