  1. Hi guys, I bought a zybo board and did a simple hello world project to test the functionality, but it didn't work. Here's what I've done: After exporting hardware and creating sdk projects, I downloaded the bitstream & program into zybo as usual. But the board wouldn't run the program normally(It doesn't terminate and doesn't print helloworld). So I debug the board using xsdb, step by step, and find out that disassembly result is not the same as elf file displayed in SDK. xsd shows that data at 0x100000 is 0xea020049; however, in the sdk, the data should be 0xea000049, as shown i
  2. I am new to this so I am just guessing how to out stuff together. I want to use the PmodI2S2 for Stereo Audio Input and Output. I am using a Cora z7 with a ZYNQ. I want to try and make two things: A. Connect the PmodI2S2 via Axi and then write a software application in Vitis to send and receive audio data. B. Connect the Pmod12S2 to logic and modify audio data. Possibly make an oscillator. The "Pmod I2S2 FPGA Volume Control Demo" in the resources centre says it uses an AXI streaming interface. So for part A. I made a new IP with an AXI streaming interface (ju
  3. so i created this project , to display the video from camera OV7670 through VGA on my Zedboard , only using the PL part , the synthesis runs good but i when i try to generate the bitstream i get these errors that i can't seem to understand : error 1 : [Place 30-574] Poor placement for routing between an IO pin and BUFG. If this sub optimal condition is acceptable for this design, you may use the CLOCK_DEDICATED_ROUTE constraint in the .xdc file to demote this message to a WARNING. However, the use of this override is highly discouraged. These examples can be used directly in the .xdc fil
  4. I'm trying to get the Pmod Color module for the Zynq z7-10 to work but it doesn't appear to be on. I was following along the instructions from these sites: https://reference.digilentinc.com/learn/programmable-logic/tutorials/pmod-ips/start https://projects.digilentinc.com/arthur-brown/displaying-color-readings-with-the-pmod-color-and-python-ebd794 and I have it connect to the device as such on the board's JA port: Following along with the first link, I skipped the steps where a clock and interrupt were added as the data sheet shows that the Pmod Color IP does not requi
  5. Hello, I am currently developing a project with the ZmodADC1410_Demo_Baremetal of Eclypse-z7. The development environment is vivado 2019.1. I use the lwip software protocol stack in the SDK, RAW API mode, and I want to use UDP through the Ethernet port on the PS side. Send the adc data to the PC (only the data of channel 1), I have now completed the spectrum analysis of the collected data on the PL side based on the adc demo, and then sent the data to the sCH1in [13:0 ] Port of the ZmodADC1410AxiAdapter IP, now I have encountered difficulties in writing the PS-side program. I am conf
  6. Hello, I have been successful in running the lwIP echo server on the Zybo Z7 board. However, I want to develop a web server on Zynq. I have gone through the lwIP documentation. However, in the discussion of this topic, I was successful in reading the .bin file from the SD card. Now I want to set up a web server on Zynq so I can command the server to read the .bin file from SD card and store it in the DDR. How do I start working on the web server. I have been searching a lot for the tutorial or anything that could make me understand in a simpler way but I failed to find any.!
  7. 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
  8. I am trying to make RAM work on my zybo; however, it keeps failing the memory test, I have tried https://forums.xilinx.com/t5/Processor-System-Design-and-AXI/ZynQ-DRAM-fails-in-test/td-p/834342/ https://forum.digilentinc.com/topic/15755-ddr-issues-on-zybo-z7-20/ additionally, I have tried setting up different "memory part" in the settings in vivado according to these reference manuals https://reference.digilentinc.com/reference/programmable-logic/zybo-z7/reference-manual/ https://reference.digilentinc.com/_media/zybo:zybo_rm.pdf Do you know what I might be doing wrong?
  9. Hi. I'm using zynq board. I'm a beginner. In my design, I used aurora8b10b IP (with framing mode) . It has AXI_ tdata, tkeep ,tlast,tvalid port. I controlled these signal in my custom logic. What I want to do is reading a frame data from aurora on the PS side. When I see the axi stream fifo, I have similar ports. Can I use this? Or should we use DMA? Please tell me the proper way. thanks
  10. Hi, While there are many examples showing a basic Hello World using a Zynq UART, how do we read in data from the console using the same UART? Can anyone please guide me to the right example. I cudn't find one.
  11. Hello, I took everyone's advice and I played around with quartus and vivado and honestly I like quartus but I digress. I think I want to get a hybrid SoC/FPGA device to play with instead of plain FPGA. My question is, does the vivado webpack allow for full ARM baremetal development/debugging on the Zynq devices provided by digilent? I found out rather late that Quartus "community" edition doesn't support baremetal development(a ridiculous omission since you're developing an FPGA hybrid but anywho....)
  12. Hello. My system clock on my arty z7-10 board is 125MHz. When I try to simulate this clk in my test bench with a single port RAM, it does not work, and only outputs zeros, however, the simulation does work with a 6.25MHz clock. I looked at the 7 series memory usage guide, and some other xilinx forums, and thye said the BRAM should be able to run at around 200 MHz, so I am not sure why my simulation doesnt. The first picture is the 6.25MHz clock and everything is running fine. The second picture is the 125MHz clock where nothing happens. Testbench is below and sour
  13. We are using a JTAG-SMT2-NC for JTAG access through one of our daughter cards. This has worked in the past using KU115 and VU5P FPGAs paired with a Zynq. However now the VU9P the JTAG chain is unstable in Adept and Vivado hardware manager where most of the time it will not correctly scan the chain and give device IDs that do not match with devices in the chain. Is there an incompatibility with the JTAG-SMT2-NC and the VU9P FPGAs? Thanks, David
  14. Hi everyone, I am looking for some guidance here: I need to interface my PS processor (user space application running on PetaLinux) with an IP created using Vivado HLS. My block design is shown below. I just want to pass some data to my IP (sha256), have the calculation done on PL and return the value to my processor ARM Cortex-A53 on the PS. From a block design perspective, am I missing something? Do I need to add an AXI DMA in between my MPSoC and my AXI interconnect? Appreciate your help
  15. Hi all, New to the FPGA world as I was tasked a project to help familiarize myself with the programming and function of how FPGAs work. As you can all infer, I am in need of some help on a specific project that I am doing. I am using a ZYBO Zynq 7000 development board, and Vivado 2019.1. What I am trying to do is control an external sensor, or LED through some user interface. I have seen a lot of tutorials that use the on-board LEDs, and if you press a button, it displays that value in binary in a command terminal. My task that I was to do is be able to turn on and off an exter
  16. Any & all help is appreciated with this thread. I am 100% new rookie to FPGA. I purchased the Digilent Zybo Z7: Zynq-7000 ARM/FPGA SoC Development Board (Zybo Z7-20 with SDSoC Voucher) My intentions are to crypto currency mine a new FPGA algo called Odocrypt created by the blockchain group Digibyte DGB.

  17. Hello, is there any image processing library that can be used for standalone applications on ZYBO? Thanks, Toni
  18. Hi. I'm beginner of zynq. When I was designing with hdl on spartan6, I drew a timing diagram and designed a state machine to make the desired signal from the desired state. So, I've already designed a state machine. However, I am not sure because I am going to use this state machine in combination with the aurora ip and gpio ip of xilinx. I want to design to interact with gpio1 in some states and gpio2 in others state. (i mean that read value from gpio to PL side in specific state.) For do that, do i design a state machine in custom axi ip? Can i control it only
  19. Hi, I am working on a project where i'm using Digilent zybo AP SoC with xilinx vivado for Hardware design and Xilinx SDK for software design. My application uses following protocol/peripherals: 1. UARTns16550 PL side (Programmable Logic) in interrupt mode. 2. GPIOs 3. Ethernet mac (lwIP stack) I started my software design using xilinx lwip perf client application project. Then i started modifying the perf client C code according to my need. My project contains Uartns16550, tcp/ip server and client program which receives real-time data. So coming to my problem, i am able
  20. Hi! In previous topic i have asked about first start with Zynq core (i have Ettus E310 board) Now it is time for connecting ADC that is on board AD9361 . I want to get some signal and receive it via ADC - i do not understand how to connect ADC (how to edit Zynq for getting data via RF board connector (via LVDS??) https://files.ettus.com/schematics/e310/e310.pdf) I have read manual (p.34) about that ADC https://www.analog.com/media/en/technical-documentation/data-sheets/AD9361.pdf I hope, somebody help me to edit blocks or code in Vivado and get digitalized data from A
  21. I want to use GNU RADIO to design an RF signal receiving circuit. For this I plan to use an FPGA card in the baseband section of the circuit (to handle the decimation and, if possible, to convert analogue to digital signal). My doubt lies in knowing if it is possible to communicate the FPGA card to the GNU RADIO application directly or if necessary from an external program. At this point it should be noted that I work in windows 10. I'm quite new on the subject of FPGA and GNU RADIO. I would really be grateful if you help me with this problem. The card is a Xilinx Zynq-7000 Developm

    Stuck in SDK

    Hi, I'm stuck in SDK. I want to control my hardware design through the use of IP cores, but can't seem to get my software to run properly. I cant even xil_printf nor light some LEDs on my Zybo z20. Any suggestions? head.h helloworld.c
  23. Hi folks, I hope all is well with you. I am a newbie to zynq AP SoC. I started working with Digilent Zybo board, lwip ethernet echo server example. Problems facing. 1. Auto Negotiation failure if i set the link speed to auto in bsp. If i set link speed to 1000Mbps the program says that the ethernet link is down. 2. How to modify the echo server program where i can send and receive data to a specific ip address with specific port number as Server and also as client. I am using a Xilinx SDK version 2018.3 Operating system: Windows 10 Happy to hear a best
  24. Hello everyone, I'm new to Zybo board and I have a question about it's HDMI port. Is Zybo's HDMI port capable of 3840x2160 video signal output at either 30fps or 60fps? If so, how should I modify the HDMI TX demo? I tried to add timing parameters for [email protected] like this: static const VideoMode VMODE_3840x2160a30 = { .label = "[email protected]", .width = 3840, .height = 2160, .hps = 4016, .hpe = 4104, .hmax = 4400, .hpol = 1, .vps = 2168, .vpe = 2178, .vmax = 2250, .vpol = 1, .freq = 297 }; But I always get 240MHz pixel clock frequency when the program runs, which re
  25. I'm trying to boot a Zedboard using a SD card, and it fails. The Power good LED is on, but the 'Done' light remains off. I tried 4 different SD cards (all UHS-I), but later read that UHS-I cards aren't supported, so I'm using a non-UHS card and it still fails to boot. MIO6:2 headers are '01100', which is the SD card boot configuration. I've also shorted JP6 on the board. VADJ is at 1.8V The board boots successfully from QSPI - the blue LED and 4 red LEDs come on. I formatted the SD cards using both: the official SD Card Formatter & Windows 10's inbuilt 'Fo
