  1. When I try to program my board after I generated the .bit/.bin files, i get the following error [Labtoolstcl 44-26] No hardware targets exist on the server [TCP:localhost:3121]Check to make sure the cable targets connected to this machine are properly connectedand powered up, then use the disconnect_hw_server and connect_hw_server commandsto re-register the hardware says no hardware exists on the server, even though my board is plugged in with the mode jumper in the JTAG position. I also tried reinstalling Vivado to make sure the cable drivers were installed.
  2. I have been working on developing an I2c interface on the arty s7 board, and during one of my hardware tests, I noticed that my debug LED's had shut off. I went to resend my bit stream and noticed that my hardware manager was no longer connected to the device. Whenever I plug the device in, it is clear that I am getting power, as the done LED, the power LED, and the TX LED are all on. However, when I attempt to reset the device using either the reset or program button, no change occurs (that is, the strobing LED pattern does not commence as it has in the past). I have checked my device manager and found that the s7 is no longer connected, and have restarted my computer as well as unplugged and replugged the s7. My primary concern is that this may be a hardware issue, but I am unsure as to what I could have done to cause this. I have been running 3 3.3v pins from the arty to a teensy. Any advice would be helpful. Thanks, Micah
  3. Hello everyone and nice to meet you. I am a user of Zybo and until today everything was fine. But today I tried to use this board with a BLDC motor control board and something went wrong... The motor was not connected to the board, but battery was. The goal was to check correct operation of the MOSFETs (by PWM) at the control board and check it with oscilloscope. When I didn't see what I wanted to see, I turned Zybo off and back on, but it didn't turn on. The symptoms are as follow: - Short circuit between VCC3V3 and GND; - All other voltages are not short circuited; - The voltage converter seems ok too. Unsoldered R259 (zero Ohm resistor between converter's output and other circuit), but short circuit still remains. - Resistance of the pin used for PWM (to control MOSFET hi-driver) is infinite; - Zener diode connected to this pin changed its internal resistance as well (unsoldered it but it didn't change anything); - All other PMOD pins have finite resistance ~600 kOhm; - The PWM pin was surely connected to an input pin of the MOSFET driver. Is there any way to check if it is a permanent internal damage of FPGA without unsoldering it or not? I am pretty sure it happened because of that PWM pin but don't know why exactly. It might happen because of static discharge (though Zener diode should protect against it) or incorrect connection somewhere else by accident. Thank you for your time. Hope to get some hints soon. Regards,
  4. Hi, I am trying to rebuild the arty z7 petalinux BSP as per the instructions given by them here But when I try the command $ petalinux-boot --jtag --prebuilt 3, I get an error saying [skaat27@localhost Digilent-Arty-Z7-Linux-BD-v2016.2]$ petalinux-boot --jtag --prebuilt 3 ERROR: No subsystem configuration file can be find in the project. sh: lsb_release: command not found webtalk failed:Invalid tool in the statistics file:petalinux-yocto! webtalk failed:Failed to get PetaLinux usage statistics! Anybody knows what the issue is? Karthik

    Connector components

    I am wanting to custom build interface connector to replace standard flywire setup Want to limit number of wires and do some twisted pair and shielded longer input wires Want to find mating keyed 30pin connector and crimp inserts, dont want to use individual wire connectors or splice , want to use key to ensure pinout and avoid splices I have seen assorted kits of Dupont 2.54 mm connectors available but the correct keyed plug to connect to the AD2 is critical. It is usually not good idea to try to repin these so looking to do a clean build, not modify Digilent flywires The new Digital HS adapter plug wont do the job for analog. It would be good if Digilent offered wiring kit with assorted pin count connectors , pins and tool
  6. I recently went to use my Analog Discovery 1 and I found that it was giving me all sorts of strange results that I did not expect. I figured that the calibration must have drifted since I hadn't used the device in a year or so, but when I performed a calibration it was still significantly off. Here's a link to an album showing comparisons between the AD1's readings versus a multimeter: . I don't really know what to do at this point, but perhaps someone here has run into this issue before and can recommend a fix. Thanks! Edit: For what it is worth, I have tried using different USB cables, different ports on my computer, different computers/operating systems, different jumper wires, and a different breadboard all to the same effect.
  7. Trying to find information regarding how I can be sure that LabView Home will work with a particular piece of hardware. I might end up with one of NI's USB DAQ devices (like a USB-6000), or a DATAQ DI-149, or a Labjack U3-HV, or anything similar. Does LabView Home require a specific driver to recognize any of these devices? Is there a decent selection of those drivers readily available? I am trying to put together a simple DAQ system that will have RPM measurement up to around 20,000 rpm and two different full bridge strain gauge setups. LabView will would be much nicer than trying to use the software that comes with the Dataq or Labjack devices. Also - does LabView Home have the same capability that the full LabView has where you can write out an executable to run instead of having to run through LabView itself?
