PYNQ - Kria kr260 | No devices Found Error

Support

Hello AMD PYNQ Community,

I am currently working with the Kria KR260 board and facing an issue while using Jupyter Notebook with the PYNQ Framework. When I try to connect to the board or run code inside Jupyter Notebook, I always get the following error message:
“No devices found”

My Setup:

  • Board:Kria KR260
  • Tools Used: PYNQ Framework and Jupyter Notebook
  • Host Operating System: (e.g., Ubuntu 20.04 or Windows 10, etc.)
    *Connection Method: Ethernet (IP: 192.168.10.XXX)
    *Power Supply: Verified and working fine

Steps I Have Tried:

  1. Verified network connectivity between the host machine and the board.
  2. Checked the board’s IP address using ifconfig/ip a to ensure it is accessible.
  3. Tried rebooting the board and resetting network settings.
  4. Reinstalled Jupyter Notebook and reloaded the notebooks.
  5. Ensured the PYNQ libraries are installed with the correct versions.

The board seems to boot up normally, with all LEDs lighting up as expected.
I can connect to the board using ssh xilinx@192.168.10.XXX.
Jupyter Notebook runs and displays the interface, but it cannot detect any connected devices when running the code.

I would appreciate any guidance or troubleshooting steps to resolve this issue.
Are there any specific settings missing that might prevent Jupyter Notebook from detecting the devices?
Does it require additional libraries or specific configuration for the board?

Please let me know if you need additional logs or screenshots to help diagnose the issue.

Hi @Marah_Mahamid,

Welcome to the PYNQ community.

Did you follow these steps to install PYNQ? GitHub - Xilinx/Kria-PYNQ: PYNQ support and examples for Kria SOMs

Hello @marioruiz,

I followed this tutorial: https://community.element14.com/technologies/fpga-group/b/blog/posts/blinking-a-led-with-pynq-in-kria-kv260-kr260

I believe it includes the same steps as the ones you sent!
