The proposed fix for moving the Demo declaration to the C file worked for me in 2022.2. Please make sure that the Demo.verbose bit is set, and what error messages are you seeing?

(added the 2022.2 text as the only other change to ensure I was running the right project)
It's possible that an IP minor version change in the I2C controller could be affecting things, but the changes between rev 2.0 and 2.1 of AXI IIC appear to be pretty small.
To check possible differences, what revision of the board do you have (mine's a new rev F), and have you successfully run the demo in 2018.2?
Thanks,
Arthur
 

Hi @RAJAT99,
I was able to get the project set up in Vivado 2018.2 using the release files as described in the readme, without encountering errors, and managed to record audio from line in and play it back over hph out. What version of the tools are you using, and what are the specific errors you encountered?
Thanks,
Arthur

The oldest version of the Zedboard board files I can find on our Github specifies revision D.3: https://github.com/Digilent/vivado-boards/tree/9926feb0998c04eb82fdf30883f2ebbf20a2dfd8. These may still work for the Rev B, but I can't confirm.
Some of the older support materials for the Zedboard can also be found here: https://github.com/Digilent/Zedboard-old, can't tell which rev it targets, but the DMA demo in there also has Zynq settings.
Apologies to not be of more help,
Arthur
