I have a simple SPI connection between my FPGA and a Raspberry pi. In signal tap, I am looking at a clk, data pin, and an enable pin. I also have a counter signal so I can tell where I am. My trigger is on a transition of the enable pin. My signal Configuration is Transitional mode. All four items I am watching are black. Signal tap stalls in this mode waiting for a signal. It will run in continuous mode. Please help.
