  1. I need to make a UI on C#.NET or LabVIEW and wirelessly(WLAN) speak with an communicate with an application for hardware control running on linux fundamentals based Single Board Computerr. What is the best and simple approach to complete it? NOTE: linux based application will be written in C/C++.
  2. Hi all, I've built with the Nexyx4 DDR board a system running Linux. In my running HW design, I've added the onboard temperature sensor of the board and the PMOD A connector to connect a I2C TMP3 temperature sensor. The HW interface for the onboard temperature sensor is the AXI IIC interface. For the TMP3 sensor with the Digilent's vivado library (as explained in:, it's the AXI LITE IIC interface. With the Linux I2C tools, I see the onboard sensor: nexys4ddr:/# uname -r 4.14.0-00493-gb6

  4. I am trying to boot Linux with Linaro file system on Zybo Z7-10 without Petalinux. I would like to connect a monitor to HDMI TX output to be able to see Linaro graphical interface but I am getting errors while Linaro Ubuntu is booting, and nothing is being shown on the monitor. I am sure that HDMI output works on my board since I got HDMI demo project to work. I am using Zybo base system design from here, adapted to Zybo Z7 on Vivado 2018.2. I have generated device tree from this design using Xilinx SDK following this tutorial. I am using Digilent's u-boot and Linux kernel and I
  5. Hello: I am unable to get Ethernet interface to work on Genesys-2 in my design which is migrated from a Xilinx board. I have a Microblaze based design that I am trying to port to Genesys-2 Board. This design is working on Xilinx KC705 evaluation board which uses the same Kintex-7 FPGA as Genesys-2. On this design I have Ethernet interface, DDR3 Interface and some other peripherals. We are using Linux for this design. This design was originally developed by another company and was used for evaluating their chip. It was developed on Xilinx evaluation board KC705. This company does no
  6. I am trying to access the audio codec SSM2603 on ZYBO over i2c interface from linux user-space for some register get and set, what i did so far I enabled in the device-tree PS I2C_0 in system-user.dtsi &i2c0 { ssm2603: [email protected]{ #sound-dai-cells = <0>; compatible = "adi,ssm2603"; reg = <0x1a>; }; i2cdetect -l output i2c-1 i2c Cadence I2C at e0004000 I2C adapter i suppose i2c coec should appear on address 0x1a but nothing i2cdetect -y -r 1 0 1 2
  7. Hello, i have a problem with the Vivado SDK. I like to include some c Header: #include <stdio.h> #include <unistd.h> #include <stdbool.h> #include <string.h> #include <arpa/inet.h> #include <sys/select.h> #include <sys/socket.h> Eclipse tell me, that my includes are unresolved. I think that is because i have nearly thirty directories in my Vivado 2017.2 SDK Installation, but it is not defined what directory exactly should be used. Can anybody tell me what is the correct include path for a 32 bit Linux a
  8. Hi, guys, I am in need of a Digilent board to run Linux with a GUI to have access to IOpins and peripherals, and also to work together with the vhdl codes on the FPGA. I am not sure how to install Linux on SD card, start a boot from there, ANDhave at the same time a vhdl code running on FPGA that I could edit and compile using the vivado (2018.2). The idea is to have the vhdl code running the hardware and the GUI on linux to present values of input, output, make the configuration on-line of the vhdl variables, etc... I was thinking about the Zybo board. Can someone give me,
  9. Hi, I came across this tutorial that @Commanderfranz created for the Zybo It is also referenced here:, which also includes the "Embedded Linux Tutorial for the Zedboard". As far as I can tell the Embedded Linux Tutorial for the Zedboard uses the Xilinx ISE instead of Vivado. What differences will there be to follow the "Embedded Linux Tutorial for the Zedboard" tutorial in Vivado? Likewise, what differences will I have to make if I follow the https:
  10. Hello, I recently received a PMOD wifi (the digilent one). I want to connect it to my zybo, already running linux-yocto with spi interface etc ... So I don't think I need the IP pmod wifi, I can make the connection myself. My question is, is there a getting started to make work the PMOD wifi ? e.g. some code to comminucate with the module. regards, Yohan
  11. I'm trying to install the Linux Runtime under cygwin on a Windows 10 platform. Getting this message on the first library file: I checked to make sure lib64/ exists, and it does, so I don't understand the error. Could this be a privileges issue? I am the administrator on the PC. Do I need to do something to run with root privilege? I did install the SDK without this problem. Hope someone can help. Thanks, Vic
  12. There do not seem to be any specifications for CPU platforms and Linux OSes that work best with the Analog Discovery 2 (i.e. that run the software and can keep up with the sample rate of the device). I see from past questions that it doesn't work properly with any model of Raspberry Pi (seems to be a Pi hardware problem, not Digilent's fault) and there are problems installing certain libraries on various Linux versions. From my experience with the HackRF One, you need a powerful enough CPU that can keep up with the sample rate being generated by the device without overruns or totally cons
  13. Hi, I'm running Arch Linux ( on Zedboard and I'd like to use the OTG-USB as a host, but my Zedboard doesn't seem to detect the device plugged in (I've tried a USB flash drive). What are your suggestions? I've followed the instructions on , but Zedboard just won't see the device.
  14. Hello all, I have a question pertaining to my ZedBoard. I'm running Linux on the PS using the built in SD card slot. I'm simultaneously building an isolated system in the PL, currently consisting of a Microblaze running a baremetal application. Now I'd like to run Python in the PL without touching the PS setup. Could I use the SD card Pmod to persist Linux to run on the Microblaze? I know I can't touch the existing SPI since it belongs to the PS, and I'd also like plenty of storage. Thank you for your time
  15. Hello, my ethernet for my Zybo doesn´t work with Linux. I use this linaro as my rootfs. Additional I follow these instructions to create my Design with all necessary files. My Linux boots up, but I got the message "no phy found". I´ve update my device tree with this: ZyboEthernet.dtsi &gem0 { #address-cells = <1>; #size-cells = <0>; clock-names = "ref_clk", "aper_clk"; clocks = <&clkc 13>, <&clkc 30>; compatible = "cdns,zynq-gem", "cdns,gem"; interrupt-parent = <&intc>; interrupts = <0 22 4>; local-mac-address = [
  16. I would like to get a HDMI Video output working with Petalinux on the Zybo Z7-10, and would appreciate any pointers, links etc. I'm particularly interested in how you get Xilinx DRM working on the Zybo Z7-10. I've seen quite a few posts on the old (VGA) Zybo, and running Xillinux, and also designs using the Xylon video cores. My design will be based on zybo-z7-10-base-linux. Eventually, I'd like to get an Ubuntu installation running Xfce working. Thanks Andy PS I eventually managed to get Lubuntu running on the Zybo - but with remote login (xrdp
  17. Hello, i made the following design: You can see two GPIO Ports: - GPIO_RGB_LED, 3 Bit, Output only - GPIO_SW, two data bits plus one interrupt bit (e.g. Input clk), this port should throw Interrupts into the Linux App. After i build that design with Vivado, i used petalinux to create a Linux image. Here you can see the "/dev"-Folder which contains the installed Drivers: You can see three GPIO-Drivers. Now my question: In former questions i ask for the Driver Support in Linux and how i can write or use them. You told me, t
  18. Hi! I've implemented a Microblaze system on the ARTY board, which includes a Texas Instruments DP83848 PHY chip to manage ethernet communications. Xilkernel and example program 'echo server' works wonderfully, so any hardware issue is discarded. However, on linux (using both mainstream and xilinx' github repo), I can't get ethernetlite core to work. This is the info I can provide: axi_ethernetlite_0: [email protected] { compatible = "xlnx,xps-ethernetlite-1.00.a"; device_type = "network";

  20. Hi all, I m beginner in Fpga, actually i dont know anything in FPGA. Last week I bought a zybo z7-10 board from diligent store. I want to run a linux on this borad, for that i did everything as per the tutorial link: And i installed linario in the sdcard. I only have a VGA monitor to connect to zybo, so that i used a vga to hdmi converter and boot the zybo. But i cant see nothing in the screen except the text "Input Not Supported". Three leds in the board is lighted up and glow still. I dont know , whats th
  21. I had a working Debian 8 production system using python2.7 to talk to an Analog Discovery 2. I decided to update the .deb packages to be current and now I get "Segmentation fault" "stack smashing detected" when I try to start my python program. I was using the amd64.deb files: digilent.adept.runtime 2.16.6 digilent.waveforms 3.5.4 (for the file) Upgraded to digilent.adept.runtime 2.17.1 digilent.waveforms 3.7.5 Also on the system is digilent.adept.utilities 2.2.1. I tested just upgrading the runtime package and my program works. Upgrading t

  24. Hi all, I m a beginner in FPGA. Last month I got a Zybo Z-10 board from diligent web store. Started working on it using Vivado 2017 edition. I played with leds and switches in PL section. Now I want to run linux image on this board. I tried many tuturials which showing how to boot zybo with linux. but failed. As in the tutorials, I created sdcard with two partitions, one with ext4 and another with fat and then I copied devicetree files, boot files etc in one partition and linux files in another partition. When I boot the board with sdcard monitor shows a black screen with som
