Notes

Lab 1

  • If DMA transfer doesn't work properly or hangs forever, just redo the tutorial step-by-step carefully. Don't complain because it is a relatively simple process that gets you familiar with the toolchain anyways.

Lab 2

  • Very useful video before doing lab 2: Merge FIFO
  • Useful commands
# Check if PYNQ's package contents recognises / includes your driver 
import pynq.lib
help(pynq.lib)

# Check IP types in your overlay
overlay.ip_dict

# Verify correct driver associated with your IP
print(type(overlay.<your_ip>))
