  1. Hello all, I'd like to connect a Pmod peripheral to the JF connector of Zybo z7-20, however, looks like the board files do not include this interface. When I open a new block design on Vivado, the "board" tab shows only JA through JE connectors. Do I have to manually map it? Maybe use the master xdc file? I'm using Vivado 2018.2 and the "new" board files from github. Thanks!
  2. I have problems with HDMI demo on ZYBO Z7-20, The demo runs well but the resolutions are not correct its kind of crops the stream, the other problem is that on photos and videos red lines appear on edges of the objects and gradients, this happens on videos and photos and not on text, for example if I watch a youtube most of corners of objects get this red lines and other texts for example video description looks normal
  3. Hi everyone, Hardware: Zybo Z7-20, PCam 5C, sd card Software: SDSoC 2017.4, reVISION platform for Zybo Z7-20 (release, v2017.2-3) The “Simple Filter2d Live I/O demo for Pcam5C” is perfectly working (following the readme in reVISION download archive). This code is the starting point for my application. My C++ skills are far from expert level and also quite rusty. I’m developing a live video application for my master thesis. The current step is to implement motion detection. The (simple) concept is to compute the difference between a background image a
  4. Hello everyone! I wanted to challenge myself and I tried implementing an I2C master capable of configuring SSM2603. I've been so far unsuccessful, not even an ACK shows up when attempting a read. Here's the wave I'm generating (I'm trying to read reg 0x6) compared with the phases as described in the datasheet. They look the same both in Post-implementation timing simulation and when checking the probes. The ACKs from master side A(M) and ~(A(M) are given unconditionally for the time being. Question 1: do you see any issue here? Question 2: The tool infers OBUFT for ac_sda
  5. Hello everyone, I have just started a project with the Zybo Z7-20 board and I am trying to build a simple system using Vivado IP Integrator. I have added the Zybo Z7-20 board files to the Vivado but the board still does not appear in the presets for Zynq Processing System. Also I was not able to find any presets tcl file for the board in the internet. Does any one know where can I find this presets tcl file for the board is there any reference Vivado project for the board to start with?
  6. I am doing an image processing (not video) with Zybo Z7, and I am writing my own algorithm in C and C++ language for the image processing algorithm. For the simulation (without camera), I have some ready photos that can be loaded from SD card and then I want to test the performance of my algorithm on. I know Xilinx provide xsdps driver for the SD card, but I don't know how to use it for my project. But For the real application, the image processing will be done on the photos that are taken regularly by a camera. My priority, for now, is to first test my code using simulation
  7. Can someone guide me how to get Petalinux working on Zybo Z7-20? I am using Vivado and SDK 2018.3 on Windows 10. I prefer using prebuilt images and files if they are available. I found this link, but it seems it is very old, and I am not sure if I can use it on my version of Vivado and SDK: The Xilinx links for Petalinux are available here: If there exists any other easy method for installing any
  8. hello, I practice to use vivado 2018.2 to create two AXI GPIOs like the first picture. I could use C program to pass the ON/OFF from switchs to leds;however, the XGpio_DiscreteRead() is always blocked by gets() when i want to use gets() to get cmd,and write data to leds according cmd. The following is my C code.Please introduce me to solve the problem. Thank you a lot. #include "xparameters.h" #include "xgpio.h" #include <stdio.h> #include <stdlib.h> #include "sleep.h" int main(){ XGpio output,input; /* SW &LED Instance */
  9. Hello! Here is another newbie question from me! I am having a running hardware project from Vivado, and I also debugged bare metal code with SDK. Both was running perfectly. Now I also got a PetaLinux (v2017.4) run on my Zybo Z7-20. So far so good. First I thought, that I could only paste the c code on PetaLinux, compile it and let it run. But of course it didn't worked because I used bare metal code. I wrote already that I have to add drivers to the device tree. Here are my problems/questions: 1) I wrote something the following files: system-user.dtsi,
  10. Recently I bought ZYBO Z7-20. I installed Vivado, SDxIDE, VivadoHLS (both 2016.4) on the Win 7 PC and started studying. I'd like to implement an arbitrary digital waveform output program to the Pmod port of ZYBO. Although I could generate a waveform using Vivado SDK's XGpio_SetDataDirection (), the accuracy is bad. (Example: 1 us width specification → 1.4 us) I would like to realize arbitrary digital waveform programming with determinism with resolution of 100 ns in the Pmod port of ZYBO in C language. (In the next step, I would like to realize a structure that measures the arbitrary wavef
