Now that the system is built, you can test it in hardware emulation.
In the flow navigator, click on Start Emulator under HARDWARE EMULATION
On the Start Emulator pop up window, keep the default settings and click Start.
NOTE: You can use the option, Show Waveform, to open the Vivado Simulator, and observe the waveform from the PL signals. If you select this option, make sure you run the simulation in Vivado simulator as QEMU will wait for it.
You should see the application running successfully with no error in the Vitis console.
To stop the emulator, click on the x on the Start Emulator line in the flow navigator
