- Using PYNQ-Z2 Image v2.6
- Using Vivado 2019.1
My Issue: I am creating custom overlays in Vivado 2019.1 that use the physical pins on the PYNQ Z2. The pins I configure don’t seem to receive inputs and outputs.
- I put in my hardware blocks and related IP in the block design of Vivado.
- I want to have my custom RTL block to connect to two of the Arduino pins of the PYNQ, i.e. AR0 and AR1. So I right click and hit Create Port, configure it with a custom name, bit-width, and specify it as an in-out, and I connect it to the RTL block, which gives me no errors in the Validate Design.
- I then run a synthesis, afterwards I open the Elaborated Design where I click on I/O Ports, then click on the port I created and assign them a package pin (the ones for AR0 and AR1) and making sure the voltage standard is LVCMOS33
- Finally I save and generate the bitstream for the overlay.
After this process, I don’t see any signals on my configured pins. Is there another method or am I doing something incorrectly?
