  1. Hello! I'm working on tutorial how to port and use PYNQ with Eclypse-Z7 and now I'm stuck on ZMOD integration. I have created device-tree-overlay based on PL.dtsi generated by petalinux with PYNQ-PRIO, applied some changes by hand and I don't know why I'm getting this error. Everything is here: https://www.hackster.io/bartosz-rycko/eclypse-z7-pynq-porting-guide-3dd24c If you could help me on this I would be grateful. Thanks :)
  2. Waveforms stopped working for me recently on one of my Linux machines (it still works on other machines with same Analog Discovery unit, same distro & kernel). On the one machine, I now always get an error dialog: Device opening failed. The device is being used by another application. Device programming failed. I've checked, and AFAICT, it is not being used by another application. The ftdi_sio driver has disconnected as it should, and no other application aside from waveforms has that usb device open. Any ideas on what might be causing this error? The only thing that cha
  3. I would like to integrate PMOD NIC100 with Microzed board with Zynq 7020 running on linux. I have a SPI interface routed through the PL logic. Are there any IP that can be directly imported to Vivado for this ? OR Are there any drivers that can be installed on the linux ? Please suggest.

  6. I'm fairly new to Linux and Waveforms, so apologies if I am missing something obvious. I am trying to install Waveforms on a Chromebook with Linux support enabled. The version of Waveforms I am attempting to install: digilent.waveforms_3.12.2_amd64.deb The version of my OS: $ cat /etc/*-release PRETTY_NAME="Debian GNU/Linux 10 (buster)" NAME="Debian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=debian The error I get when trying to install: The following packages have unmet dependencies: digilent.waveforms: Depends: libc6 (>= 2.14)
  7. I burn a Linux image using Yocto, meta-xilinx and openembedded put after put all the required files on SD card and put it on my FPGA (ZYNQ-ZYBO-Z7020) and try to connect with it using serial communication (putty or realterm) the output is wrong I am using 115200 baudrate and this is the baudrate that recommended in the data sheet
  8. Hi, I'm using a RPi4 with Analog Discovery 2 and I'd need to use AD2 at 64bit so I'm wondering why you are not sharing sources to build libraries for a specific system with proper optimization. Best, pz
  9. Just received a new Genesys 2 board. Flashed it and trying to boot the prebuilt version of linux from arian-sdk Programmed the board according to here: https://reference.digilentinc.com/learn/programmable-logic/tutorials/genesys-2-programming-guide/start The board powers up fine, copies bbl & linux image from sdcard and then no tty output. Nothing at all. I built the sdcard using the prebuilt bbl.bin images from: https://github.com/pulp-platform/ariane-sdk/releases (I tried bbl.bin files from both 4.2 release and OpenPiton + 4.2, same result for both.) Following instr
  10. Analogue Discovery 2 https://forum.digilentinc.com/applications/core/interface/file/attachment.php?id=12669 https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019Ls1SAE&l=en-US Hi Firstly I would like to say what great product the Analogue Discovery 2 is, I have used it for 8 months to develop a product. It is by far the best PC scope that , I have used. Far better than a PICOSCOPE from the UK company PICOSCOPE or any of the Chinese PC scope knock offs. Analogue Discovery 2 is a serious peice of professional kit and not a toy. This a summary of all
  11. Hello to everybody! I'm built custom Embedded Linux distro which based on Digilent Base-Linux FPGA design (https://github.com/Digilent/Zybo-Z7-20-base-linux) with help Xilinx Petalinux env. In this design was implemented XADC support. From the default BSP package from Digilent repository, I added support XADC to the device tree. How I can test this implementation from a working Linux image. I need to write a driver or I already can work with XADC?
  12. Hi all, Currently I am working on a project with the aim to encrypt the communication between a drone and the ground station by using an PYNQ-Z1 board. I am facing the issue of how to convert the standalone application (bare metal) to a Linux base application in Vivado 2019.1 SDK, in order to make use of the crypto++ libray which requires the presence of an perating system to work. Does anyone know what to do to slove the issue? Thanks George
  13. Hello Everyone, I just want to know Is linux interview tough? My interview has been scheduled in next week. Can anyone provide me list of interview questions for linux profile as a fresher level. I have covered some most important topics like Linux, BASH and DOS, symbolic links, daemons and some more.
  14. Hi all, This is a quick and dirty howto. This howto describes how to use I2C modules (onboard and through PMOD connector) under embedded Linux. I've chosen to build my own Linux distro based on Linux kernel source for MicroBlaze softcore and busybox project for the init RAM DISK. My board is the Nexys4 DDR board. If you respect the following requirements for the HW design compatible with Linux, you can use Petalinux too. HW Vivado requirements (according to Xilinx UG1144) design to boot Linux: MicroBlaze with MMU support by selecting either Linux with MMU or Low-end L
  15. 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
  16. Hello everyone! I'm trying to install Petalinux on a Cora Z7-10 I followed all the steps described here: github.com/Digilent/Petalinux-Cora-Z7-10 but when I try to boot it I get this message: hwclock: can't open '/dev/misc/rtc': no such file or directory after this, I can't write anything in Minicom. As in my folder /dev didn't have the misc folder, following some advice that I found on the net I created the folder and first tried to soft-link /dev/rtc0 and then hard-link it also but none of those worked, I still get the same error. Did anyone go through the same issue
  17. Hi, We have a custom embedded board with a Zynq processor. There is a JTAG-SMT2 on the board connected to the JTAG chain of other boards. We want to use this for Fpga configuration as well as remote ChipScope debugging. I think I've the runtime code installed correctly (/dev/ptmx is created when the JTAG-SMT2 is detected). But I can't compile the DjtgDemo program to compile: armv7l-timesys-linux-gnueabi-gcc-color -O3 -Wall -I../include -I../include -I../drivers -DCPC_TARGET -I ./Digilent/digilent.adept.sdk_2.4.2/inc -L ./Digilent/digilent.adept.runtime_2.19.2-armhf/data/usr
  18. 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: https://github.com/Digilent/Petalinux-Zybo-Z7-20 The Xilinx links for Petalinux are available here: https://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/embedded-design-tools.html If there exists any other easy method for installing any
  19. Hello, I am having trouble outputting sound on Linux using SSM2603. The SSM2603 device driver loads normally. It is also registered in ALSA sound card list. However, "input / output error" is raised in "alsactl init". ("amixer" is also the same.) It plays when I play wave file with "aplay" but it does not output to "R/LOUT pin" of SSM2603. Regards, Namio
  20. So I have the BeagleWire FPGA cape for the BeagleBone Black and I want to send interrupts from the FPGA to the linux os on the BeagleBone every time a switch on the cape . The BeagleWire consists of the Lattice iCE40HX4K FPGA. I understand this is done through GPIO and that an interrupt request line has to be set up but I need specifics and a better explanation of how to actually code this is Verilog. I'm new to FPGAs, just starting out, so any help would be appreciated. Details regarding the BeagleWire including its open source software, can be found below: https://www.crowdsupply.com/qw
  21. Hello, I have a new open logger and want to put it to use soon. I have a couple of issues. I'm hoping Digilent can respond. First, I cannot update firmware from ubuntu ... I have a windows 10 partition and have used that, but that is a pain. When will the linux system function normally? Second, I want to log some data using wifi as having a usb cable attached is not an option in my application. I cannot get the thing to connect to my system or even show any wifi networks. This happens in linux and windows. When will I be able to connect this way? Finally, will I be a
  22. Hello! I have the following question. Is it possible to read Zynq temperature via XADC when working with Digilent Linux distro on PYNQ-Z1 board? Thanks!
  23. Hello everybody, I'm new to this forum and to fpga programing and I got a question: is it possible to implement a linux on microblaze and having non linux-managed blocks (classic logical blocks) at the same time? and how to realize that. I got the webpack suite of Xilinx (vivado + sdk), i'm working on windows but got a ubuntu virtual machine ready. To define the project, a little draw: For the linux implementation, i found @loberman manual, i was close by myself but it's realy helpfull. Thanks guys
  24. 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++.
  25. 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: https://reference.digilentinc.com/learn/programmable-logic/tutorials/pmod-ips/start), 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
