  1. Nexys Video No Hardware Target Exists

    @wangjianli, You have a private message and an answer in the topic you opened. Best regards, Bianca
  2. There is no current hw_target.

    Hi @wangjianli, You have two Port COM listed. In the USB controllers I see just 1 device connected. Do you have two boards connected on UART or just one? If it's just one you should not have two COM ports. This looks to me like you corrupted the content from the EEPROM and the board is no longer recognized. I didn't understand if this happens just on one board or on both. I will private message you with a solution to see if we can have the board recognized again. Best regards Bianca
  3. No Compatible Board Interface

    Hi @FarmerJo, Why are you trying to implement your project with Microblaze and not using the ARM in the ZYNQ? It's not impossible to add a microblaze on the FPGA side but you'll end up with two processors. Do you need two processors? If not, I suggest you to follow the tutorial with the ZYNQ. https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-getting-started-with-zynq/start Best regards, Bianca
  4. Protection Diode and Fuse Damage

    Hello @yyuan, Is the diode hot? Take care if you touch it cause if it really is you'll get burned. You can try to remove the diode and see if the board if it powers again. You might have a chance of getting it back. Also, I would recommend not just removing the diode, but replacing it. If the board works without diode, SMBJ5.0A is its part number. Good luck, Bianca
  5. Hello @zygot, Sorry for the late reply. I wanted to try and replicate this behavior and tried to connect the board to the HW Manager without the UART to see if it crashed and it did but it took it more than 5 hours. After that I opened a terminal to see what is happening. I checked Vivado after about half an hour and the target was already disconnected. We started to look into the issue to see exactly what is happening. Best regards, Bianca
  6. Nexys 4 DDR

    Hi @nac, Please check your private messenger. Best regards, Bianca
  7. Hi @akavia, Please check your private messenger. Best regards, Bianca
  8. Sorry, I just checked the project and the one published is Rev C. I looked for the Rev E but I can't find it. I will come back to you after I get the correct revision. Best regards, Bianca
  9. Hello @akavia, The PCB project for the max32 is public on our reference page here: https://reference.digilentinc.com/reference/microprocessor/max32/start You can find it on the table from the right at Physical Design Resources. Best regards, Bianca
  10. Analog Discovery WaveForm Generator Failure

    Hi Nicolas, I’m sorry to hear that. Unfortunately, we also don’t have the resources (tools and technicians) to repair the broken boards. Even if you didn’t make the mistake to connect the wave-gen with the scope and everything was wired up correctly, you would’ve ended burning your device because Analog Discovery 2 is not capable of measuring 80V, its limit being 50V. Since this isn't a manufacturing defect, it is also not covered by warranty so we can't replace it. I’m sorry we can’t help more. Best regards, Bianca
  11. Impact 13.2

    Hi Jennifer, I believe impact 13.2 is not compatible with the 64-bit operating system. Try the latest version 14.7. We use this one on 64-bit op systems without problems. Best regards, Bianca
  12. New Update to Waveform 2015

    Hello @expplane, You don't need to uninstall the previous version. It will make you an update with the current one. Best regards, Bianca
  13. Nexys4 ddr protect cover

    Hi @pake342, Unfortunately, we don't have Plexiglas cover for the Nexys4 DDR. Best regards, Bianca
  14. Nexys Video Board Layout file

    Hi @praveen You'll find the Nexys Video step file on the reference page, here: https://reference.digilentinc.com/reference/programmable-logic/nexys-video/start?redirect=1 Best regards, Bianca
  15. Hello, Unfortunately, we can't release the layout files for the Nexys Video since part of the design is proprietary. Regarding the step file, we can provide one in few days. Best regards, Bianca
  16. JTAG-HS2 firmware erased by accident

    Hi @Sklozgos, Check your private messenger for the solution. Best regards, Bianca
  17. Digital Discovery with 5V Logic

    Hi @Joey Gold, It is 5V compatible, which means that you can see 5V signals. You won't be able to output from the Discovery 5V signal because the source is not capable of any of that. Best regards, Bianca
  18. Analog2 for 2 photon microscopy?

    We have the Electronics Exporer which has 4 scope channels but only two channels for AWG. It's more expensive and includes a solderless breadboard and +/-9V variable power supply, when the Discovery would give only 5. I don't know if these features would help you on your project or on the future. You can see the product here: http://store.digilentinc.com/electronics-explorer-all-in-one-usb-oscilloscope-multimeter-workstation/ and the resource center with the reference manual and the full specs, here: https://reference.digilentinc.com/reference/instrumentation/electronics-explorer/start?redirect=1 Bianca
  19. Analog2 for 2 photon microscopy?

    Hi @amchagas, Sorry for the delayed answer. It is possible to perform all these with AD2 but only on 2 channels for output and also you can record only two signals. You can't control the hardware with custom software, but, as Zygot said, the current software offers the possibility of writing custom commands based on existing APIs. Best regards, Bianca
  20. 410-319 Mounting

    Hi Matt, Unfortunately, I can't really see how you could put the board in a chassis. It wasn't designed for screws but for rubber feet. Normally, we keep both in mind and we put holes on the board even if it will have rubber feet like the Basys3 has but in the case of Arty this was not done and you have buttons or traces and plans on the corners of the board. Sliding the board into a chassis can't be done ether because on the right part of the board you have some resistances close to the edge. On the left, the USB and Ethernet port will keep you from that. On the upper part the PMODs are preventing that and on the bottom you have some resistors and transistors pretty close to the edge. Maybe fixing it with some plastic clips where you can find open spaces. I'm sorry we can't help more. Best regards, Bianca
  21. Hi @dzabakh, Some of out distributors are qualified to sell with academic discount. You should contact the distributor and see if that is the case. We can sell in Russia, as we have distributors but we can ship directly there. If you are situated in another country were we can ship directly, I believe that is possible. If you gave all the details and the academic account was accepted I suggest you to contact sales directly at sales@digilentinc.com to give you the exact details of the procedure and you'll see what suits you best. Best regards, Bianca
  22. Hi @bwheeler, I'll step in just a bit and maybe @jpeyron might troubleshoot further with you and I'll take over tomorrow if it's not solved by then. To make sure I understand, you opened the device manager and it says "No target open" which is normal, then when you clicked on auto connect you didn't have the variant of programming the device. After INFO: [Labtools 27-2285] Connecting to hw_server url TCP:localhost:3121 it needs to go further and and open the hw target but I guess it just latches there and this is why you don't have the option of programming the device. Please send me a screenshot from Vivado to see exactly how does look your local host. I will need also o sceenshot from your device manager to see if the board is recognized by the computer at all. Please open the device manager, without the board connected through USB and then power it on and see if something does appear and what. You said that you have a new laptop? So if I get this straight, you had the Arty for a longer time, worked on another laptop/PC but does not work on your Dell. Is this right? -If that's right, I need to know if you used the same version of Vivado on the other laptop you had. I'm also thinking of a Vivado bug so If you could try with a more stable version like 2016.4 would help me a lot. -If it's not, please try to connect your Arty to another computer and see if the problem persists. Best regards, Bianca
  23. No valid target connected to the server

    Hi @Vivadong69, Please see the document attached. In addition, please make sure that the USB cable has data wires not just power and if possible try to use another one, which you used before for data transfer. Best regards, Bianca Device Manager.docx
  24. Hello @dzabakh, Due to recent changes in export restrictions, we are unable to ship directly into Russia. We recommend you purchase Digilent products through an authorized reseller. You have here the list of our distributors. Best regards, Bianca
  25. No valid target connected to the server

    Hi @Vivadong69, First of all, is your board powering? Can you see the demo running on the board? I need to tell you to make sure that the board is on when you try to program it. (I had users who didn't turn the board on, so I need to take every step with everyone). Second, like Dan said, I need a screen shot to see how is the board recognized by the computer. Can you send me one and make sure you point out the device or tell me if nothing shows up. That error is typically given when the board is not powered. This is why I need first to know that the board is powering and you can see activity. Send me the screenshot and we'll see from there what is the issue. Best regards, Bianca
