  1. Hi I am trying to install waveforms to use the analog discovery box. I am in Linux using Ubuntu and I have downloaded both adept and Waveforms and tried installing both using the terminal and everything seems like it installed but when I search to open Waveforms I can't find it. I'm not sure what is wrong or why they are not installing properly. I'm using the 64 bit for both. Please Help Thanks

    Hi all, I'm new in this world and I hope someone could help me in this issue I'm working on a project in the Uniersity where I would like to use the Zedboard as UVC device to stream video from FPGA to the host. I'm able to build, configure and run the kernel from SD but I'm having some problem to connect the Zedboard as peripheral mode and to detect it as UVC gadget. In particular I've configured the kernel to act in peripheral mode following this instruction : http://www.wiki.xilinx.com/Zynq+Linux+USB+Device+Driver To let the Zedboard act as gadget I started from this gui
  4. https://reference.digilentinc.com/reference/software/sdsoc/reference-manual I am trying to run this design on zybo (hdmi_in project). I was able to have the baremetal design running on the board. But I am not sure how to have the linux version running as well. But there is no clear instructions on the link. Can some one help me get through the process? Thank you
  5. Hi ! I'm still working to add a RF module (MRF24J40) on my zybo. The SPI communication works fine, but I have some trouble with interrupt. I'm using linux-yocto as kernel. Here is the design in vivado : The AXI_GPIO 0 and 1 are to use leds, buttons and swtichs on zybo. The AXI_SPI is used to communicate with MRF24J40. And the AXi_GPIO 2 is 3bits wide, one for wake, one for reset, and one for interrupt (for MRF24J40). The interrupts are enable on the AXI_GPIO2. I don't know if it is a good practice to enable interrupt for wake and reset too ? Here is the interrupt enab
  6. Hello everyone! I am working on a project witch need a linux image to run for SDSoC. The base project that i am using is this, but I upgrade it to the 2016.2 version. I supposed that i need to upgrade the linux files too, to the 2016.2 version. In fact i did it, I use Petalinux to finally get the files in the irst image, but I don't know what is the next step, I don't know witch files have to be copied (and rename) to the boot directory in the main project. Regards, RaulRB
  7. I have installed Adept 2 and Waveforms 3.3.7 from the Digilent website. I can open the Waveforms software and use it in demo mode with no issues, but the moment I plug in my Analog Discovery 2, the application crashes. The .crash file is too big to upload directly, so I have uploaded it here: https://dl.dropboxusercontent.com/u/971295/_usr_lib_digilent_waveforms_waveforms.1000.crash This issue is entirely deterministic with my setup, so please let me know if any additional information would help.
  8. Hi, I am using Xilinx Zynq UltraScale+ MPSoC ZCU102 Evaluation Kit and I am newbie for using this board. I'm following this link to generate an interrupt using GPIO switches and turn off a led : http://www.wiki.xilinx.com/Linux+GPIO+Driver. The drivers works correctly and the led is heartbeating, when i check /proc/interrupts i get: ... 223: 0 0 0 0 GICv2 154 Level fd4c0000.dma 224: 0 0 0 0 xgpio 0 Edge sw14 233: 0 0 0 0 GICv2 97 Level xhci-hcd

  10. Hi, In mine development, I have booted Linux on ZedBoard and also i have integrated the Wi-Fi module successfully with the ZedBoard. Now in mine further development i want to explore the partial reconfiguration thing on the ZedBoard as i do not have any idea about this. From here and there i have read some PDFs which talks about some PCAP , ICAP and many more ...but i did not able to get these things fully. So as per mine requirement i would be sending one file(mainly partial config) to the ZedBoard via Wi-Fi. In this regard till now, i have sent one file(that is not reconfig
  11. I have a weird issue with my Analog Discovery 2 and I was wondering if there are ideas out there how to track it: I use a Digilent Adept with the Waveforms 3.3.7 software on linux. It seems to work fine but does not detect my triggers. If I use the provided pyhton examples or C examples trigger detection does not work meaning the program just stays in "Waiting for trigger" state all the time. But if I use the dwfcmd: cd /usr/share/digilent/waveforms/samples/dwfcmd && dwfcmd analogintrigger.txt I get one trigger without a problem. It took me so much time to de
  12. I am unable to make Waveforms working with my Analog Discovery on Linux. I installed Adept 2 and Waveform, when I plug my device in the usb port I have it recognized. It seems it is Waveforms that refuse to recognize the device or something bad happen as soon as I start Waveforms to the USB connection. Here is the log output when I connect the device in the USB port: oct 06 20:49:09 feynman kernel: usb 2-1.7.4: USB disconnect, device number 11 oct 06 20:49:09 feynman dbus[1324]: [system] Activating via systemd: service name='org.freedesktop.Avahi' unit='dbus-org.freedesktop.Avahi.servi
  13. With the original linux installed on my Beaglebone Black the scope worked but then I installed a newer debian version with a 4.1.22 kernel and now I keep getting an error with scope power: dwfcmd analoginout.txt FAILED: FDwfDeviceOpen The device needs at least 2W/400mA from USB cable. To satisfy this: - Try to use different USB cable and computer plug. - Use the USB plug on the back of the PC, not the one on the front panel. - Use short cable, do not use long cable or cable extender. - Use powered USB-hub, avoid un-powered hub. - Use 5V auxiliary
  14. I'm new to FPGAs and the zynq. I'm interested in a zybo board and would like to know how to put an lvds output on the logic part of the zynq and how to get this connected to a framebuffer device I can use in linux to output graphics to?

  16. I'm trying to use an Analog Discovery 2 on linux Debian 8.5 (jessie). I recently upgraded from 7.9 (wheezy) because I couldn't get the AD2 usb to work reliably.

  17. I've been battling trying to get the Analog Discovery 2 to work on usb in linux (Debian 8.5 now) on the cpu board I have from VersaLogic (Iguana). At this point, usb keeps disconnecting and I can't tell if it's the board or the drivers. My preference would be for an ethernet Analog Discovery 2 instead of usb since my experience with usb seems so flaky compared to ethernet. But can someone suggest a small motherboard with a usb chipset that they've gotten to work with linux and the AD2? I'm hoping for something small like a mini-ITX. It needs wired ethernet and video. Any help, or a
  18. Hi all, I am currently doing the Xilinx tutorial to run Linux on my zybo : http://www.wiki.xilinx.com/Build+FSBL In the process, I have to get these task done : Bitstream (for the programmable logic portion) System hardware project hdf file My question is : can I use the https://reference.digilentinc.com/_media/zybo/zybo_base_system.zip ...to generate the bitstream and the system hardware project ? If I complete the tutorial with the generated files, will I be able to run linux and use it with the hdmi or vga output, get access to any kind of command prompt?
  19. Greetings everyone, This is the first ever post of a beginner who has set on the path to learn embedded systems. Please forgive me if haven't followed rules of posting. I took the embedded system plunge few weeks back. Bought a strong laptop, a Zybo board, OV7670 camera, installed Vivado. Read online tutorials like 'blinking LEDs' and 'HDMI-to-VGA out' (and the others ones in Zynq Book) to get myself accustomed with Vivado etc. [Abbreviations in the text: PS= Processing System, PL= Programmable Logic] I have been visiting a blog lately and have found that quite helpful. A couple of

  21. Hi all, I am trying to add an axi-timer to generate an interrupt from PL to PS. I found this guid of xilinx here : http://www.xilinx.com/support/answers/62363.html My question is how to or where to find the three numbers assigned to interrupt like in this example of xilinx: "interrupts = <0 59 4>;"? I am using ZYBO and Vivado 2015.4. Thanks,
  22. Hiiii, i am looking for answer of this question. How to set that a particular thread always be executed by a specific core in multi-core Linux environment?
  23. Hi all, I am about to run Linux on a Zybo. In the tuto I am following, this is explained I have to generate a device tree after defining the hw with no mention about any Linux drivers. But I think this is not the only thing I have to do to make Linux able to communicate with the peripherals on the board. Tell me if I am wrong : the device tree is just there to tell the kernel how peripherals are mapped in memory. But it does not tell nothing about how to communicate with. This is the role of the driver. Right? If right, will it be fine if I generate the device tree and if I use
  24. Hello, I've successfully installed Waveforms 2015 v3.3.3 and the Adept runtime 2.16.1 on my machine which is running Fedora 21. Both are 64 bit. However, when I plug in the Analog Discovery 2 it shows no device detected. I tried reinstalling the Adept runtime, and the FTDI drivers with no success. The Analog Discovery 2 does show up on my machine as a USB device however. It shows up as "Future Technology Devices International, Ltd FT232H Single HS USB-UART/FIFO IC" Thanks! Kaitlyn
