Hello, I am working on arty z7-20 in vivado. I have add zynq processing system and enabled SPI0(EMIO), all other settings are default. I have made SCLK pin of SPI as external. But when I connect external SCLK pin to scope I see no output. What is the problem? Actually I want to communicate between two ArtyZ7-20 boards through SPI pins present on board, one of them is master and other one is slave. I am particularly new to fpga and vivado. Can someone help me with the steps please.
