Cannot Read data from MAX10 UFM
Have you selected burst count after you assert the read signal?
You may follow the user guide available at link below for the steps to perform read operation:

I believe I am following the User Guide. avmm_burstcount is set at the same time avmm_read is asserted, I'll attach a waveform.

Is there any more feedback for this issue?

I also get the following warning messages throughout the simulation:
