  1. Hi Everyone! I'm attempting use Waveforms with Ubuntu 15.10. I've installed Adept runtime, and Waveforms 2015 through .debs. Waveforms on start only displays a blackscreen and the terminal reports the following error: waveforms: pthread_mutex_unlock.c:87: __pthread_mutex_unlock_usercnt: Assertion `type == PTHREAD_MUTEX_ERRORCHECK_NP' failed. Aborted (core dumped) If I attempt the cli I receive the following: Set range and print the actual obtained range: dwfcmd connect analogio channel=1 range=5V range dwfcmd: pthread_mutex_unlock.c:87: __pthread_mutex_unlock
  2. Digilent Waveforms depends on xdg-utils which depends on x11 and many things. Can I install waveforms without all of this and how? Is anyone using this on an embedded device like the Beaglebone Black or Rasberry Pi?
  3. I have an Analog Discovery 1. I have been using it successfully under Windows for some time. I would now like to use it under Linux - Ubuntu 14.04 LTs (64-bit) . I have installed digilent.waveforms_3.2.6_amd64.deb When I start the program I get three error messages 1) WaveForms > dlopen libmgr.so Reinstall Digilent Adept Runtime 2) WaveForms > No device detected 3) Device Manager > Adept NOK No device appears in the list of available devices in the Device Manager. Running dmesg I can see that the device is recognized by the operating system. Whe
  4. Hi, I am trying to write a linux device driver for a project which uses audio codec. I am using the ip axi_i2s_adi codec for the project on ZYBO . I see that the functions in the demo file are written for Vivado. I mean the functions uses XIlinx header files and functions. I think I cannot use those to build device driver. If somebody has written device driver by themselves or know where i can find, please share the details with me. Thank You, Ramu

    Moving to Linux

    Hi all, i'm moving my development environment to Ubuntu. Last things I'm struggling with are Xilinx WebISE and the JTAG-HS3 programmer. All worked fine under W7pro. But WebISE performs traumatically on Ubuntu. WebISE was designed to run on RedHat and SUSE but it runs there far from flawless. So I put up a W7 in VirtualBox on Ubuntu and got WebISE running fine again. But when forwarding the JTAG-HS3 to the VM, the VM got killed immediately. I can live with this situation if I knew how to operate JTAG-HS3 on Linux, to upload a bitstream to my FPGA. So my questions boil down to: Where can I find
  7. Hey Guys, I am trying to install a Preempt_RT patch on the linux. I downloaded the Linux kernel from github which is described in 'Embedded Linux Hands-on Tutorial': https://github.com/DigilentInc/Linux-Digilent-Dev.git . I noticed that the kernel version is 3.18.0, so I install the patch 3.18.24-rt22.patch (since there is no patch for 3.18.0). But when I try to compile the patched kernel with the configuration of full RT, I got this following errors: So I am wondering how to solve this. And I also wonder if there is anybody else trying to use a real time linux on the zybo. Regards, Jimmy

    Nexys4DDR Linux

    What happened to the Embedded Linux topic on the Nexys4DDR wiki page? It was "under construction" and now it's removed. I was looking forward to see this project since I got my Nexys4DDR. What happened? Didn't the Artix7 have enough power or did Nexys4DDR have to few ressources? Regards, Jago
  9. I am using Ubuntu 14.04 and VIVADO 2014.4. I am trying to boot Linux on a zybo (7000)board, I tried to generate a bit stream and it is showing that the synthesis is failed. I have also attached a file. I also have a voucher from the digilent and used to generate a license file .lic. I opened the license manager many times and showed the license path and it said that the license was successfully installed.
  10. I've successfully installed Vivado 2015.3 webpack and generated a bitstream for the Arty GPIO demo. On Linux, the Xilinx installer does not install "cable drivers"; apparently you are supposed to install those yourself, somehow. But I am sure not what I need for the built-in JTAG on the Arty board. Do I want Adept 2 Runtime or something else? From within the Vivado HW Manager I don't see any driver-install options, and it presently says it cannot find any hardware attached. Thanks.
  11. Hey guys! I followed the ''Embedded Linux hands-on tutorial'' to build and run Linux on my ZYBO board. I am trying to use the Ethernet but it seems does not work correctly. Here are some informations: I connect the board and my PC (ip adr: 169.254.29.208). When I ping ZYBO from my PC I got "Destination host unreachable" and "request timed out". When I ping PC from ZYBO I got "sendto: Network is unreachable". I'm using Vivado 2014.2 under Ubuntu 14.04 and didn't do any changes in addition to the tutorial. So anyone can help me with this? Thanks a lot! Best regards, JImmy
  12. After doing the hands on linux tutorial for the Zybo I have some grasp on how to access custom IP in linx. However, I'm confused on how to access the three other registers that the IP core has in the demo. I know its using a file transaction to get the user data and write the data to the IP core register in the kernel space. Would I have to modify the kernel module source to parse the message and then do an IO write to a indicated register or do I have to write enough data to get to the desired register? Also how would I go about reading specific registers using the procfs method? (i.e. I want
  13. Here you can find instructions on how to set up Linux and WaveForms 3 for Zybo: http://www.instructables.com/id/WaveForms-Analog-Discovery-on-Zybo/
  14. Hello guys, I followed this tutorial "Embedded linux on zybo" http://www.instructables.com/id/Embedded-Linux-Tutorial-Zybo/ and everything works like a charm, I compiled the linux kernel and u-boot from digilent github, as a next step I said i'll be debugging Linux C apps. I'm trying hard to debug a linux application coded in xilinx SDK (2015.1) according to the follwoing two links: http://www.xilinx.com/support/documentation/sw_manuals/xilinx14_7/SDK_Doc/tasks/sdk_t_linux_application_debugging_system_debugger.htm what happens that when i try to press Debug, i got in the debug perspective ..
  15. Juergen Sauermann published a classic oscilloscope like application for Linux, based on Qt and WaveForms SDK. This project can be found on the following location: https://sourceforge.net/projects/qtoscilloscope/
  16. I’m a PhD student working in a mechanics laboratory in France (LMT Cachan) and one of the goals of my thesis is to control a hydraulic testing machine using digital image correlation techniques. In order to do this, I need to take a photo of a sample, process it, extract 4 parameters and send them to the testing machine. This process needs to be repeated at a frequency of approximately 80Hz. We need a device to send these values from a Linux computer to the 4 analog entries of the machine (0-10V, 0.5 mA) by coaxial BNC cable. We managed to do this for one channel using an USB connected oscill
  17. I just installed WaveForms 3.0.25 (digilent.waveforms_3.0.25_i386.deb) under Debian Wheezy and I get the following error: dpkg: dependency problems prevent configuration of digilent.waveforms: digilent.waveforms depends on libc6 (>= 2.14); however: Version of libc6:i386 on system is 2.13-38+deb7u8. Is there a solution for this without having to reinstall the whole operating system or using chroot/docker like solutions? strange enough waveforms _does_ work despite this error message kind regards, hugo p.s. a big thanks for making the software available for linux users

    Nexys4 ddr resource

    Hi, are there some news about nexys4 ddr resource time to release of Embedded Linux Materials and Advanced Microblaze Design with MIG, Ethernet, UART & GPIO ?
  19. Finally I arrived tu run petalinux on nexys4ddr launching by jtag. Now I'm trying to generate boot file for SD/USB drive but I have some difficult because fpga can't read MCS file, just BIT by SD/USB. It's possible convert MCS to a BIT ? Any help ?
  20. Hello, I am fairly new to linux and I am trying to program a cerebot nano. I have the JTAG-USB cable with SPI, rev. b. I have downloaded wine and the AVR programmer but I don't see the device when I enumerate in the AVR programmer. If I use djtgcfg enum, from the terminal: [email protected] ~ $ djtgcfg enum Found 2 device(s) Device: DCabUsb Product Name: DCabUsb1 V2.0 User Name: DCabUsb Serial Number: 50003C003874 I did install the usb drivers that came with the AVR programmer, using wine. Any ideas?
  21. I am following the instructions in the Embedded Linux Hands-on Tutorial and got stuck at step #3 in section 4.2.

  22. Hi. I managged to run both Linaro and ArchLinux on the Zybo board, with HDMI output (but i'm gonna remove it after). But I'm having some troubles to comunicate with my custom hardware. I'm used to programming in Hardware, and I made several real time high performance applications like face recognition and real time video processing on pure verilog (Nexys 3, Nexys 4, Atlys boards), but I'm kind of new to cross-compiling, linux kernels, and drivers. I have a few master AXI modules that directly communicates with the DDR3 memory using the HP ports (no DMA, VDMA or similiars), and I just reserve a
  23. Hello, I have successfully programmed my Basys2 using the 'djtgcfg' utility under Linux dozens of times, but I'm no longer able to do so. When I attempted to program the board yesterday, I got some unusual results: > djtgcfg enum Device: 3.....O......<. Product Name: Digilent Basys2-100 User Name: 3.....O......<.

  24. Hello. I am working with an Atlys board. I am trying to transfer a bitstream file and a linux image to the SPI flash. In windows I remember doing it from the flash tab in the Adept application. Now I am working on a linux computer and I've installed the Adept 2 runtime and utilities. I've read the man pages for the 3 utilities (dadutil, djtgcfg and dsumecfg) but it is still not clear to me if it is posible to transfer to SPI flash using these utilities. Is it?
  25. Hi, I am currently using Zybo board. I have followed the " Embedded Linux® Hands-on Tutorial for the ZYBO™ " tutorial. My question is how does the Zynq system works? Is it similar to Microblaze soft processor or is it just FPGA? I have done the same work in the tutorial using Microblaze processor and XIlinx ISE. I find in the specs that Zynq hosts 2 ARM cortex processors, I want to know when we run above the above tutorial are we using any soft processor or if we are using the ARM Cortex processor? My point is if any soft processor is involved we can eliminate it and use the ARM processors
