microblaze Hi everyone, I am currently learning about communication between Microblaze PS and FPGA PL, with using FIFO as data buffer.

[RedRobin]

I am new to FPGA and Microblaze, and have implemented a simple hello world program till now using Vivado and Vitis.

Let's say I want to send an input(1,2,3,4,5,6,7,8) using an up counter. Kindly guide me on how I can begin to implement this on Vivado and Vitis using a FIFO.
Should I use GPIO Module? For FIFO should I use AXI Data FIFO, or AXI Stream FIFO?

Thanks in advance.
