Hi, as I was runing the 02_pynq_and_data_converter.ipynb. I got some error. Can you please help me? Thank you very much.

Details are :

metal: error:

I load the PYNQ 2.7 image downloaded from the official website on my ZCU111 board, and I connect the board to a network switch. I can use another computer to access the PYNQ Jupyter notebook environment, but the 9090 port needs a password. I do not find an available password to login. Any clues？

The image showing the ADC/DAC connections (README.md step 4) needed to complete the tutorial will not display.

Hi team,

I plan to change from ADC 224 to ADC 226 in the ZCU111 board.

Could you please suggest possible ways?

Thank you

Best,
Lucy
