I'm using ZC706 board and trying to connect Processing System's SPI pins to an extension board.
Here are what I did
The Vivado project's board preset was properly set to ZC706. I used a scope to detect spi signals on the extension board but no signal came out.
I thought it could be pinmap issue so connected PL signals to the same pins on the extension board and got meaningful signals.
Also I tried to connect FCLK in PS to the pins and it was detected by scope. So I think the pinmap is fine and PS is alive.
I did the similar steps on a PicoZed board and it was successful. Do you have any suggestions to solve this issue?
