  1. Hi, Before I embark on creating my own model I thought I would ask if there is a Step file available for the above mentioned Zybo Z7 board. I have an action to build an enclosure around it (unless someone can point me to one that is available for sale) and the CAD model would be a huge time savings. Many thanks
  2. We are using PL section of the Zynq7000 to transfer data to another module b y creating a SPI IP Inside the PL. We want to know that the PMOD pins availvalble on the Zybo-Z710 board are using open drain or push-pull configuration ? Do they have something like a internal pull-up resistor ? Please let me know.. Regards Amol

    Webserver using Zybo Z7

    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.! I also tried understanding the echo server C code in sdk however, after a point it seems too confusing to me. I could even think of modifying the echo server C code to develop a web server with some help, may be. The documentation of lwIP is confusing to me at this point.... Thanks, Shyama.
  4. Dear all, I'm using Vivado 2018.3 and a Zybo Z7010 board. I have finally finished my project (I actually owe this forum much), and I am now trying to use the board without having to open nor Vivado neither the SDK. Basically, I know that I can program the QSPI flash memory of the board so that the program can run without having to upload it. How this works is still unclear, is switching from JTAG to QSPI enough or should I do something on Vivado? However, I am also using the Zynq processor which runs an application that I start from the SDK. Can I avoid opening the SDK? The better thing would be if I could programm the FPGA through Matlab but I don't know if this is possible. Could you point me to some tutorials or the matlab functions (if they exist...). Thank you very much, NotMyCupOfTea
  5. Hello, I'm working on an audio project with a Zybo Z7-10 board (with Vivado 2016.4), and as a starting point I'm trying to set it up as an audio passthrough. I've been working off of the DMA audio demo, but I can't seem to get it to output a continuous stream. Is there a way to modify it so that the sound input can be immediately routed to the output without having to record it first?
  6. Hi, I am trying to learn about Zynq APSoC using Zybo 7z020. I have successfully completed all steps of this tutorial :https://reference.digilentinc.com/vivado/getting-started-with-ipi/2018.2 I have a problem that Tera Term is always printing square brackets instead of the expected output as shown in this tutorial. I am using Vivado 2018.3 with SDK 2018.3 on Window 10. Below is the screen snapshot of the problem. Could anybody please help. Thank you very much Lrni
  7. Hello again, As I continue to experiment with this development kit, I would find it valuable to be able to capture Raw images. Is that possible to do somehow? I didn't see any mention of it in the Demo documentation but it is possible that I missed it. Thanks again -Ted
  8. I plan on purchasing the Zybo z7-20 for prototyping a project I am working on. After looking at the documentation for the board it says that Vivado WebPack supports the Zybo z7 board and is fully compatible with Design Suite. I just want to make sure that Xilinx Vivado WebPack works with this board. Thanks
  9. Hi! A couple of months ago, I bought a ZYBO Z7-10 board for one of my university labs. Just recently, I was using the JE PMOD ports to interface with an external LCD display. The board was programmed through QSPI Flash through the micro USB port. Unfortunately, a external 5 volt supply leaked into the 3v3 JE PMOD peripheral when the board was powered through the micro USB port. I immediately turned off the power supply and the ZYBO board once this had happened. After turning back on the ZYBO with all PMOD connections detached (to test if the board was still functional), the default demo program that the FPGA should run (with flashing all LEDs in a smooth manner) is a very erratic version of what it once was (LEDs flash randomly). While in the QSPI Flash mode (after the incident), I am not able to reprogram my FPGA design as Vivado does not recognize the ZYBO board anymore through the USB connection. When I change the programming mode jumper to either TJAG or MicroSD, Vivado CAN recognize the ZYBO board and I can successfully field-program the board and run the program. Is it possible that I have permanently damaged the QSPI Flash (or even something worse). If not, is there anything I could do to fix this?
  10. Hi Dear Sirs, I will start to work with Zybo Z7 Development Board. But, I couldn't find any explanations about ESD & Safety protections and warnings for the board in the reference manual. Could you please provide it to me if there is anything special to protect the board from ESD? Because I don't wanna break the board when touching it. Thank you..
  11. Serial digital interface (SDI) is a digital video interface used with the most of professional video cameras. It uses BNC connector and operates at speeds of 3 Gb/s or about, depending on the standard. The more detailed specification can be found in wikipedia. Most of the SDI adapters for FPGA use FMC connectors, like this one. There is no FMC connector on Zybo Z7 board, but it does have multiple PMOD ports. Could they probably substitute? If some simple extra circuitry is required, we maybe could build it on the top of some generic PMOD adapter like this. My major doubts are, would such interface be fast enough? I am not aware at which frequency Zybo PMOD port and the custom circuitry attached to it could operate.
  12. Hello, I am new to ZYBO board. I am working on a project where I want to control a sensor from my ZYBO board using UART and receive the data from the sensor via SPI. I searched for the reference design, tutorials online to get started with, but I could not find any. Can anyone point me in the right direction where I can refer to and implement my work? THANK YOU. This is my aim as shown below. I want Zybo to be the main host, not my PC.
  13. Hi, I have been following tutorials from Zynq book for Zybo Z7 board. In tutorial 5, where the zybo_audio_ctrl IP core is used, I can not get any audio data through my board. The tutorials are made for Zybo board, and I followed migration guide (to Zybo Z7), but still no success. Any help would be appreciated. Thanks
  14. I wanted to try the example Audio-DMA project but it went really bad. This is what I did and the output from Vivado and SDK 2017.4. Source the make_project.tcl. Update the ip because I must. Get eight critical warnings, e.g., [PSU-1] Parameter : PCW_UIPARAM_DDR_DQS_TO_CLK_DELAY_0 has negative value -0.050 . Generate output products. Generate HDL wrapper so I can extract the hardware. IIC ports names differ in the .xdc so I have to change them to capital letter (IIC). Also notice that the ja ports are there, I don't know why though. Generate the bitfile. Got 1715 warnings, mostly unconnected ports. Also about some unused sequential elements removed which can be bad. Export hardware with bitfile. Launch SDK and import 'Existing Projects into Workspace', i.e., the 'sdk' subfolder which yielded this; I see this in the guide; Many apparent errors at this stage can be solved by right-clicking the bsp project and selecting Re-generate BSP Sources. Ok, try; I can open the file in any text editor but SDK just shows a big red sign and 'Failed to create the part's controls'. There is also a small textbox where I can almost scroll around and see the content. In the problems tab I see this; If I comment that include out, this is shown instead; And that path do indeed not exist. Probably because that path does not exist, so doesn't the cpu_cortexa9 2.3 either. What can I possibly have done wrong, and what are all these Java errors? Is this something I should ask Xilinx about instead? Also, before this I tried the DRAM test program as a first thing. It failed so I thought I would just try something else in the meanwhile and this is what I got. Bad start for a new board =\.
  15. I'm designing an application using the Audio CODEC of the Zybo Z7. I'm configuring the CODEC by I2C properly and could see data coming from the I2S. Then I realized that each time I programmed the FPGA, the Led 5 of the board was turning ON... even this LED is not at all part of my design!! Never mentioned in my constraints and never mentioned in the verilog wrapper. Then proceeding by elimination when analyzing the constraints, I realized that this LED was turned ON as soon as the I2S clock went enabled... with below constraints: NO LED TURNED ON ##I2S Audio Codec ##set_property -dict { PACKAGE_PIN R19 IOSTANDARD LVCMOS33 } [get_ports BCLK_0]; #IO_L12N_T1_MRCC_35 Sch=AC_BCLK ##set_property -dict { PACKAGE_PIN R17 IOSTANDARD LVCMOS33 } [get_ports FCLK_CLK1_0]; #IO_25_34 Sch=AC_MCLK ##set_property -dict { PACKAGE_PIN R16 IOSTANDARD LVCMOS33 } [get_ports RECDAT_0]; #IO_L12P_T1_MRCC_35 Sch=AC_RECDAT set_property -dict { PACKAGE_PIN Y18 IOSTANDARD LVCMOS33 } [get_ports RECLRCLK_0]; #IO_L8N_T1_AD10N_35 Sch=AC_RECLRC ##Audio Codec/external EEPROM IIC bus set_property -dict { PACKAGE_PIN N18 IOSTANDARD LVCMOS33 } [get_ports IIC_0_0_scl_io]; #IO_L13P_T2_MRCC_34 Sch=AC_SCL set_property -dict { PACKAGE_PIN N17 IOSTANDARD LVCMOS33 } [get_ports IIC_0_0_sda_io]; #IO_L23P_T3_34 Sch=AC_SDA But with below constraints enabling the CLOCK... I get the LED turning on in Red, Green or Blue depending... ##I2S Audio Codec set_property -dict { PACKAGE_PIN R19 IOSTANDARD LVCMOS33 } [get_ports BCLK_0]; #IO_L12N_T1_MRCC_35 Sch=AC_BCLK set_property -dict { PACKAGE_PIN R17 IOSTANDARD LVCMOS33 } [get_ports FCLK_CLK1_0]; #IO_25_34 Sch=AC_MCLK set_property -dict { PACKAGE_PIN R16 IOSTANDARD LVCMOS33 } [get_ports RECDAT_0]; #IO_L12P_T1_MRCC_35 Sch=AC_RECDAT set_property -dict { PACKAGE_PIN Y18 IOSTANDARD LVCMOS33 } [get_ports RECLRCLK_0]; #IO_L8N_T1_AD10N_35 Sch=AC_RECLRC ##Audio Codec/external EEPROM IIC bus set_property -dict { PACKAGE_PIN N18 IOSTANDARD LVCMOS33 } [get_ports IIC_0_0_scl_io]; #IO_L13P_T2_MRCC_34 Sch=AC_SCL set_property -dict { PACKAGE_PIN N17 IOSTANDARD LVCMOS33 } [get_ports IIC_0_0_sda_io]; #IO_L23P_T3_34 Sch=AC_SDA I'm respecting the pin allocation proposed in the Zybo Z7 manual... therefore I do not understand what is going on... Let me know if someone already faced this situation or have any idea of the phenomena. I"m using Zybo_Audio_Ctrl IP for the I2S below a copy of my design...

    Zybo Z7 PMOD IO speed

    I have a question about how to connect zybo z7 to a ADC with LVDS input and output running at 200MHz. The zybo z7 need to provide clock to the ADC at 200 MHz and receive data at this speed. The ADC's interface is indeed LVDS yet this zybo z7 board's IO bank are all 3.3V powered, which means that it cannot use the internal termination. I think I have two way to make it work. 1. transmit data and clock in a single-ended way and do the single-ended to differential conversion on my ADC board. 2. transmit data in LVCMOS33 and do level conversion in ADC board. The problems I have are that: 1. Is that ok to transmit a signal in single-ended way at 200MHz? I have no experience on doing that before. 2. If I use LVCMOS33, since I still cannot use the on chip termination, is that enough for me to just terminate transmission lines at the ADC's LVDS driver side? 3. What is the impedance on the FPGA IO pins when it is in LVCMOS mode? Thanks a lot!
  17. Hi Guys, My application on linux requires two ethernet ports on the Zybo Z7 board. So I have recently bought a Pmod NIC100 card. I read the references and I have enabled the encx24j600 driver in the xilinx linux kernel. I have enabled SPI0 controller in vivado for the Z7 board. Correct me if I am wrong, but I reckon to use the enabled encx24j600 driver, I have to add the interrupts and registers under spi parent in the device tree but I don't know the specifics of what I have to add. Can someone please help me out? My intention is to get this board to appear as eth1 in xilinx linux. I would appreciate any other way than device tree method to do this as well. Let me know if you need any other information.

    Memory tutorial

    Hi I am beginning my foray into FPGA design, and I decided that the best to to learn would be to learn on the go, and learn as I go. I am using a Zybo Z7 7020, Windows 10, and Vivado 16.4 I have a project for school which will be using PMODs as IOs and the information will have to be saved to memory of the board I am wondering if there is a good tutorial which will help me learn how to access, read and write to the DDR3

    Zybo Z7 as standalone FPGA

    Hello guys, I'm starting to work with Zybo Z7-20, and I've read this in the Zybo Z7 Reference Manual: "It is also possible to treat the Zynq AP SoC as a standalone FPGA for those not interested in using the processor in their design." Can anyone tell me how can I do this please? I just want to treat the Zynq as a standalone FPGA. Any examples on how to do that? Thank you!!!
  20. I've been trying to get the Zybo Z7-10 HDMI demo (link) to run on my board, but I can't seem to be able to compile the actual project (using Vivado 2017.3 on Windows 10). I created the project from the create_project.tcl script in the proj folder, and was able to generate the block diagram and wrapper. I upgraded the IP cores and verified that the xdc file was consistent with the wrapper. But when I try to generate a bistream, Vivado always seems to get stuck on route_design. I've left Vivado running for 4 hours and it still can't move past route_design, despite it still using ~30% of my CPU. From these two forum posts, could it be a version problem? I don't seem to have a system.tcl file in my project. I've been able to run the demo on my board by loading the provided bitstream and running the example code, but I would like to modify the demo and use it as a starting point for my project.
  21. Ubuntu 14.04 worked on ZYBO Z7-20, but at first Ethernet did not work. The cause was that MDIO of Ethrnet 0 of Peripheral I / O Pins of PS of ZYBO Z7 was connected to EMIO. In the circuit diagram of ZYBO Z7, MDIO is connected to MIO52, MIO53. In the board file, should I connect MDIO of Ethrnet 0 of PS Peripheral I / O Pins to MIO? https://reference.digilentinc.com/_media/reference/programmable-logic/zybo-z7/zybo_z7_sch-public.pdf Currently, since we connected MDIO of Ethrnet 0 of Peripheral I / O Pins of PS of ZYBO Z7 to MIO, Ubuntu 14.04's Ethernet now works on ZYBO Z7-20. This situation was also the same for ZYBO. In previous ZYBO_zynq_def.xml, MIDO was connected to MIO.
