I am aiming to utilize the USB port on the PYNQ-Z2 to connect an event-based camera with a specialized EVT data format. I need to send the data To the Programmable Logic (PL) to effectively process this data. I’ve conducted extensive research, however, I am encountering confusion regarding whether I should incorporate AXI-USB in the block diagram design within Vivado or rely on the DMA and AXI DMA, as outlined in the PYNQ DMA tutorial (Tutorial: PYNQ DMA (Part 1: Hardware design)), and use the python libraries of PYNQ(which libary and driver?) to initialize the USB device and get data.
My specific inquiry pertains to the use of AXI-USB, is it necessary or not?. Additionally, I’m curious about the absence of tutorials addressing USB functionalities, AXI-USB usage, and guidance on employing USB for off-the-shelf devices. Any insights or recommended tutorials on these aspects would be greatly appreciated (How to connect pins and set the configurations).
