  1. Hi everyone , I would appreciate if someone could help me solve this strange problem regarding Ethernet transmission of UDP packets in RAW mode with LwIP from Zedboard to Windows PC. I’m using the example project in SDK to test the functionalities of LwIP called udp_perf_client. If I try to use the project as it is (with UDP_SEND_BUFSIZE 1440 ) Whireskark signals that packet are malformed , in fact it seems that “data bytes” are being truncated so are sent less bytes than expected (declared in the costruction of the IP header by LwIP). In the image attached is shown the ca
  2. Greetings, I am looking to get the GERBER AND/OR DXF files for the Zed Board so that I can perform mechanical verification of compatibility and orientation of my MEZZANINE card to the FMC connector of the ZED. Thanks Sean
  3. Hey All, I am trying to make a simple IP block design in Vivado 2018.3 to test the ESP32 PMOD out using AT commands for data transmission. I will attach a picture of my current block diagram to this post. I am getting a critical error (reference below) that says the IP has a packaged board value of "digilentinc.com:cora-z7-10:part0:1.0" which is for the Zybo z7 board. My questions are: Q1)Will this design work regardless of this error, as the Zybo and Zed boards are similar and both run off the zynq-7 architecture? Q2)If the answer to Q1 is "no", is there a method of adapting t
  4. Hi., Im trying to run the project available in Github for Pcam 5C camera with Zedboard using FMC Adapter. Upto bit stream is done and exported to SDK Successfully. After creating Application and adding files it is showing errors. Kindly help regarding this Version: Vivado 2018.2.1
  5. Hello I tried HelloWorld example in Vitis and Vivado 2019.2 and this worked well until programming FPGA. Because I have only one USB cable to connect into zedboard PROG port or UART port, I ran a HelloWorld program with "RunAs -> Launch on Hardware(System Project Debug)" with connecting cable to PROG port and reconnected to UART port to receive outputs from zedboard. However, I got weird results(e.g. there is no outputs or there is outputs but garbled). After that, I borrowed a cable from my friend and also connected it to zedboard, and I rerun program and got appropria
  6. Hi all, I'm working on a video streming project with a zedboard and an ov7670 camera module. I found a similar project online, made by Mike Field, and I was able to make it work. But I want to buid the project using custom IP's. and I found this project: https://lauri.xn--vsandi-pxa.com/hdl/zynq/zybo-ov7670-to-vga.html I used the same (working) VHDL code, the same XDC file, the same setup, and followed his instructions, but for some reason, whenever I try to create custom IP's (with or without AXI), I can't make it work, and the monitor says "no signal". Can
  7. Hello all, I would like to generate a user-defined clock (1.8V 24MHz) out from the board. (for other devices) After I use a clock_wizard to generate a 24MHz clock and make external, which pin is suitable for assignment? 1) Choose Pmod JA1 (EPP pin = Y11), however, the pin is 3.3V in default. Should I buy a Pmod level-shiftier ? 2) Is there any other proper external IO recommended? Thanks.
  8. Hi, If anyone is interested in retro systems I've started on a port of the Multicomp system. I have a 6502 with basic up and running, you need a pmodps2 to use a keyboard (must be a proper ps2 keyboard). SD Card, Serial access, Z80 and 6809 to follow. https://github.com/mattuna15/zed-multicomp Enjoy
  9. Hello everyone, I’m a newbie on working on zedboard, and I want to use my Zedboard to communicate with Pmod MIC3 this time. I did a few researches about how to use the Pmod MIC3, and I think I found something useful in another post, link: https://forum.digilentinc.com/topic/19342-driver-code-for-pmod-acl2-and-pmod-mic3/ I’m really appreciate and thanks for their help, but unfortunately I still have no idea of how to make my Pmod MIC3 to run with my Zedboard. I know Pmod MIC3 is using SPI communication protocol and I read what SPI is, link: https://reference.digilentinc.com/learn/fund

    Artix7 & ZedBoard

    Hello, My group has acquired the two boards Artix A7 and ZedBoard for developing some applications. I am noticing couple differences regarding projects and documentation. One such difference has to do with the reference base design. For Artix A7 I am finding the PMOD ports, and I2C, SPI, UART, Ethernet included in Board connections. For ZedBoard, very few peripherals are included in the base design I was able to locate. Question: For developing new applications for Zynq, can you provide some information regarding Zynq base desing. Is there more complete project for i
  11. Hello, I am Raghu, doing my Master Thesis. I am using Zedboard to emulate few sensor's signals. I have already implemented DA1 and AD2 on to Zedboard and connected in the loop. They both work perfectly fine. But next step was to implement DA4 in my design, and I didn't find any drivers for the same. So I tried using normal AXI SPI IP in the hardware design for DA4 and tried to develop my own driver (considering DA1's driver as an example). All the initialization part works perfectly fine and the communication also takes place as per DA4's datasheet. But when it is asked to send data, it i
  12. Hi, I want to read analog data from ad1 pmod. For Vivado part, I use digilent pmod ips to connet fpga. For SDK part, I use AD1.h and AD1.c library in examples. My sensor sends to me analog values between 0-3.3V. (This is a heart rate ECG values). During using arduino, all heart beat data can be read. But I use same function for zedboard, Analog values doesnt look like arduino's. How I can configure and fix this problem? As you see ad1-zedboard connection as below.
  13. Hello, I want to access analogue pin of XADC header to input audio data in FPGA (Virtex VC707 here). But i am getting error in writing bit-stream "Partially routed nets". Design is below: As we provide the pin number and voltage standard in constraint file for pin assignment, but here the I/O Std is faded and cannot be edited. I have also edited constraint file manually but still getting this error. Pin assignment are as under for VC707 Schematics diagram for VC707 Any help will be appreciated. Thanks,
  14. Hello, I have recently purchased Zedboard along with Pmods AD1 and DA4. I want to implement Gradient Descent algorithm in the Zedboard using these Pmods with bandwidth more than 100 kHz. To get started, I tried to regenerate a analog signal using the Pmods AD1 and DA4. The experiment is completely explained with block design and output plots in the ADC_DAC_1_compressed.pdf. The SDK C code for acquistion and generation (adc_dac.c) as well as for finding max. working speed of DAC (dac_maxv.c) are atttached. The ADC clk is set to 20 MHz and DAC clk is to 50 MHz. It could be observed fro
  15. Hi, I have a ZEDBOARD which I want to interface it to an analog input signal and see the sinusoidal output. i'm following lab 3 tutorial by Adam Taylor. So, as for the first step, I tried to connect the signal generator to Vn and Vp. I expected to see the sinusoidal shape of the voltage in XADC dashboard (XADC wizard demo). and also set the ENABLE_ALL_AUXILIARY_CHANNELS check mark, which will include Vp/Vn. I set the function generator to frq 50Hz and amplitude 400-600 vpp, or DC also I applied and checked the signal on the dashboard and serial oscilloscope both. But, the boar
  16. Hi, experts: I'm using Zedboard, I try to use JC1 or JD1 to connect to external LVDS port. when I opened VIVADO, choose Zedboard, I can only see push buttons, leds, slide switches. How can I see either JC1 or JD1 so I can set it as PMOD GPIO and then connect it to my LVDS input port. I saw some examples that all the I/Os are supposed to be shown on the board window, but for my project, only a little was there. example board window: my project board window: Thanks Zen
  17. Hi All, Hereby two video's of my ZedBoard with an ad-fmcomms3-ebz daughter board from Analog Devices. Although the AD9361 is capable of much more and this is my first experiment with a SDR I'm exited to show you my progress with this simple demonstration of a FM broadcast modulator and demodulator, using a ZedBoard with Analog Devices ad-fmcomms3-ebz FMC daughter card.

  18. Hello, I am currently working on a project using the Zedboard and some Pmods from Digilent. As of now, I have booted Ubuntu 16.04 onto the ARM core using the Petalinux tools through an SD card. I have also been looking into the GPS pmod and got the bare-metal example to work from programming the FGPA. Through my personal computer (Ubuntu 18.04), I have been able to interface with the Ubuntu 16.04 on the ARM and the GPS pmod. However, I am a little confused as to how the GPS pmod in the PL communicates with the Ubuntu on the ARM. I would really appreciate some insight on the last leg of th
  19. Hi there, I'm new to the world of FPGAs, and was able to get my hands on the aforementioned Zedboard. I wanted to hook up a camera module to it for some real time processing stuff but I can't seem to find a suitable module. I've looked up PCAM-5c but it isn't compatible with my board although I did find some TerAsic although I'm not sure if they'll work or not. Any thoughts or recommendations?
  20. Hi, I am relatively new to working with the Zedboard. I've managed to get an I2C/I2S audio example working (using bare-metal) , that i've downloaded from here. http://www.zynqbook.com/download-tuts.html Now, I would like to get the same example working using the Linux Kernel. However, I can't seem to be able to access the I2C bus. The bus appears to be there, but denies access. zynq> i2cdetect -l i2c-0 i2c Cadence I2C at e0004000 I2C adapter zynq> i2cdetect -y 0 Error: Can't use SMBus Quick Write command on this bus From

  22. want to buy ZEDBOARD ZYNQ-7000 ARM/FPGA SOC. Will RTL code provided with the board? what do i expect to get? Thanks,
  23. Hey, Can I use Digilent's peripheral "Pmod DA2: Two 12-bit D/A Outputs" on zedboard ? If I check, https://reference.digilentinc.com/learn/programmable-logic/tutorials/pmod-ips/start this link, under Platforms Supported, ZedBoard is not listed. That makes me wonder if I still can use PMODDA2 and other Pmods on my zedboard? IF yes, i think we do not have an IP specificially created for PMODDA2...
  24. Hi all, Would like to find cheaper Zedboard than buying a new one. Would be very taxing to get a new board. Thanks.
  25. Hi all I'm currently working on a project based on ultrasound. I've created a pulsetransmitting board already which hooks into the zedboards FMC-LPC connector (I needed 64 high-speed channels), yet now I need to make a receiving side as well. Since returning signals are in the range of 250-300kHz, I was looking into ADCs of around [email protected] or 14bits. (max. 4 channels needed) Now is the problem that I can't find any spec on the frequency the zedboard PMODs can handle. Is it possible to have speeds of approx 20MHz or is this out of range of the (high-speed) PMOD connectors? Would it
