  1. Hello everyone , I'm realtively new in programming FPGA's and needed some help . My micro-usb port got shorted so i had to resort to programming my basys-3 with a usb drive . I followed the reference file from digilent on that and everything was working fine . I used it the same way for the next few months . I stopped using the board for a months after and when i tried programming it today again , the bit file did got programmed . INstead the busy led next to the port forever keeps blinking . I tried formatting with FAT32 , resetting , testing the demo file on QSPI but nothing works even after all that . Like i said i'm very new to fpga's and mosty just implement basic codes to learn so i'm clueless when it comes to the next step . Any help would be apppreciated . Thank you . Regards, Supriya
  2. Hi! We are working with a Basys-3 FPGA and were wondering if it is possible to read large data files from a USB stick. We are trying to let the Basys 3 produce music through a module, but the internal ROM/Flash storage of the Basys is too small for, for instance, .Wav files or .Wav converted to .coe files. Is there a possibility to use the USB stick support for programming for this application or perhaps another method? Thanks! Kind regards, Jonathan
  3. So my current project is very simple, but I've yet to settle on how the control logic is going to be implemented. I think the FSM and Microblaze are both perfectly viable solutions, but I want to find the intersection of maximum learning and minimum complexity. The controller will be performing three tasks: -Pass alternating I and Q data from another module via usb to the user. -Receive data from the user via usb to set a desired frequency. -Interface with the clocking manager to request the new frequency. I am sure I could create an FSM to accomplish this, the USB controller has already been done, my hesitation is a lack of understanding of the AXI4 and DRP interfaces. I am familiar with 8-bit RISC AVR microcontroller, and if given a similar structure, I would think designing with a microcontroller would be almost trivial, but there is surely a learning curve to climb. The question boils down in my mind to a balance between the complexity of the FSM and the learning curve of Microblaze. I also am inclined to say some introductory experience with Mircroblaze would likely be desirable for a future employer. What do you think would be a better opportunity for learning?
  4. Hello, I just opened my new basys3 board (novice EE student). As per the documentation I tried to power the board via usb-b (port j4) first through a laptop usb then through a 5v 2A charger making sure the jp2 jumper was set on usb and jp1 to the spi flash test program but the board did not turn on (not even the power good led). Trouble shooting that I performed: 1. Changed cable twice (didn't work) 2. Changed charger and usb ports (didn't work) 3. Powered board from external 5v power supply - the board worked perfectly. My question is could the smd soldering be defective, where can I mesure the voltage provided by the usb? Thank you for your help, If there is any more information I can provide please let me know
  5. I am interested in buying Spartan-7 FPGA Module: https://store.digilentinc.com/cmod-s7-breadboardable-spartan-7-fpga-module/ but first I would like to know if it suffers same USB cable issue as CMOD-A7: Since FTDI circuitries look similar on these two boards I just want to make sure the faulty design was not copied over from A7 onto S7.
  6. Hello, my friends, i am new here and it is my first project. This project will be my BSC. I have to make next: 1. Make USB CAM interfacing on System Level using systemC... My diagrams are shown in the post. I need to capture the photo using a USB CAM. After that, the picture needs to be stored in some memory. After that the image processing logic (In my case, the logic needs to have the photo (stored in memory) as its input, the idea is just to decrease the photo size (pixels) and the output is the result (decreased size picture)), after that the result of processing needs to be stored in memory too. After that i have to choose... in easier way i will use some photo viewer to see the result, in more difficult way i will use HDMI in order to see my result on the HDMI enabled monitor. My plan is making it on System Level using coding, HLS,IP integrator, SDK for some software. 2.If SystemLevel work great i need to make it on RTL, IP level using pure HDL. I will use Vivado. I am not sure for now what i need to modify from SystemC to IP level (For now, i think just Image processing logic). 3.IP verification using QuestaSim. I have a question: 1. Has someone done something similar? Can you help me, like as give me some good literature or example (For now i am focusing on USB interfacing, i have been searching about this about few days, but without results..., I have read a book (SystemC "From Ground up")). 2. All suggestions are welcome Best regards!
  7. Hi, I'm running Arch Linux (https://archlinuxarm.org/platforms/armv7/xilinx/zedboard) on Zedboard and I'd like to use the OTG-USB as a host, but my Zedboard doesn't seem to detect the device plugged in (I've tried a USB flash drive). What are your suggestions? I've followed the instructions on http://zedboard.org/sites/default/files/documentations/GS-AES-Z7EV-7Z020-G-V7-1.pdf , but Zedboard just won't see the device.
  8. HI, for my new PYNQ-Z1 to connect over its "USB HOST" interface: (1) will any USB Hub do, e.g., when concurrently a USB WiFi dongle and a USB-Webcam are connected to the PYNQ-Z1? (2) what is your recommendation(s) of a "compatible" stereo camera module (cf. attachment) for the PYNQ-Z1 board ? Thanks.
  9. Hi FPGA gurus ! I am facing trouble while trying to attach my Atlys USB JTAG device to a Centos 6 virtualbox VM. I recently had no choice but to upgrade my computer from Windows 7 to Windows 10. As a Windows 10 version of ISE 14.7 was available, I decided I could do the upgrade before realizing that ISE 14.7 for Windows 10 was indeed ISE 14.7 for Linux running a VirtualBox... Nevermind. The problem is that it seems I can't attach Digilent USB JTAG to the VirtualBox. Here is my configuration : Windows 10 Pro VirtualBox 5.2.8 (I upgraded it so that I could install Extensions to enable USB 2 and USB 3 support) Adept2 is installed on Windows 10 and works fine, Atlys board is recognized and I can run the test application OK. Now, here is my problem : Let's turn on the computer first and do a fresh test ! Atlys Board is attached to USB ports (JTAG and UART) but is turned off. VirtualBox USB configuration is configured as shown in USB_parameters.jpg Now, let's turn VM on, Atlys board still off. The attachable USB device list in VB is shown in USB_devices_atlys_off.jpg As you can see, neither JTAG nor UART devices are listed, which is expected as Atlys board is off. Now, let's turn the Atlys board on and see if the listing has changed... It has ! as shown in USB_devices_atlys_on_1.jpg Also, you can see in Device_mgr.jpg that Windows has no driver problem with JTAG and UART devices. You may notice UART device is automatically attached. Looking at /dev/tty* shows that the UART device is now available through /dev/ttyACM0 as shown in TTY_devices.jpg Let's have a look at the JTAG device status (USB_devices_atlys_on_2.jpg), it reads "captured", whatever that means ... Now, let's try attaching it... It raises an error with message shown in Digilent_USB_JTAG_attachment_error.jpg "USB device is busy with a previous request" :/ This is sad ... Of course, no other device appears in /dev/tty* Greping dmesg for FTDI pattern returns Nothing. Only UART USB devices appears in dmesg log... I've tried the same test with USB 3 (xHCI) configuration selected. Do any of you have an idea on how I could attach the USB Digilent JTAG device to my Centos 6 VirtualBox machine ? Any help will be highly appreciated. Thanx a lot. Cheers
  10. @Bianca @Rainer Urian can you help me ? i am also working on zybo board and suffering from same problem. my usb port ( j10 and j9 ) are not getting detected . can you tell me how to resolve this issue ?
  11. hello, I am interested in the following reference design: https://reference.digilentinc.com/learn/programmable-logic/tutorials/nexys-4-vga-test-pattern-with-mouse-overlay/start The design currently does not provide any sources: Is this project abandoned? I believe it had not been updated since 2015. Is there a later version available (this one, perhaps, or on github?) I am interested in the USB host with mouse, which I intend to implement on the Zybo/Zybo-Z7. Do you provide the sources for this project? Is there a project you can recommend, There is also the BIST for the Zybo-Z7, maybe it contains relevant references? thank you
  12. Hello, I have been using the WiFire board Rev D for data collection. A data stream is sent from the WiFire board to the windows computer over USB. Programming is via Microchip Blockset for Simulink: http://www.microchip.com/promo/mplab-device-blocks-for-simulink Downloadable code is auto-generated by Simulink (CTRL B to build) Program loading is via Pickit3, the .elf file is attached. This system was working fine, but suddenly the windows system can no longer see the com port. How can I fix this? Thanks, John ChipKit_WiFire_32MZ2048EFG100_Standalone_R2015b.elf One more note: the WiFire board should show up in Windows Device Manager as a com port, and it does not, see screen shot. If I plug in an Arduino, it shows up as COM4, the WiFire should look similar. John
  13. Hi all, I m a beginner in FPGA(zync 7000). I want to implement a project which took images from two cameras, one with usb(uvc) interface and one with csi-2 interface. One thing to note that i not using both cameras simultaneously. Only once at a time(Switch over whenever required) With first USB camera, i want to do some image proseesing functions like filtering and CLAHE(Contrast-limited adaptive histogram equalization) on the captured image. Then the processed is images is displayed on a HDMI or RGB interface mini projector(DLP 2000). Here i indicated both HDMI and RGB interface because of i need to test the performance of both interfaces with HDMI input projector and RGB input interface TI DLP 2000 mini projector. And I also need to display the image which is captured from the second CSI-2 camera and do a little enhancements, then display it in a DSI 5 inch LCD screen(51 pin MIPI DSI) the details link of cameras , projectors and lcd is given below USB Camera: http://www.elpcctv.com/mi5100-5mp-usb-camera-module-usb20-aptina-125inch-color-cmos-sensor-100degree-lens-p-221.html CSI-2 Camera: https://www.waveshare.com/product/rpi-camera-f.htm DLP 2000 RGB - projector: http://www.ti.com/tool/DLPDLCR2000EVM HDMI projector: https://www.ebay.in/itm/302673956725?aff_source=Sok-Goog Display : https://www.alibaba.com/product-detail/5-inch-720p-oled-display-720_1925219941.html?spm=a2700.7724838.2017115.42.6ba11d77AqfGq7 Can anyone please help me to build this project. Just give some basic idea like 1. which zynq version is suitable for this application? 2. Board design, start from scratch zynq design or any SOM modules having zynq 7000 3. Hard core or soft core ip? 4. best evaluation board for this design? I also need suggestions for above said questions. I want to do this in an industrial design way, so that i m asking help from others and I m just a beginner in this field, expecting good support from this forum. Great thanks in advance....................
  14. The attached image is probably the easiest way to ask this question .. We want to program 6 devices all at the same time using 6 copies of a USB-JTAG device (as opposed to having once large JTAG chain). It looks like Impact / Vivado does not natively support this (it sees multiple dongles but only deal with them one at a time). Can we script something to load a BIT file on all 6 simultaneously? We currently have the XUP USB-JTAG Programming Cable but would switch to another one if this one can't do it. Thanks!
  15. I've got a problem with using my AD1 board, WaveForms is not detecting it anymore and it seems to be a usual problem with micro usb connector. I've checked continuity between connector pins on the pcb and the usb cable end and there is no connection between black/red wires and sides pins, only green/white seems to be connected to middle pins. Hence next I will try to replace micro usb connector but I couldn't find the same as used on the board. Can anyone have BOM/ part number for the connector?Or can I use any connector like molex (part number 47590-0001)? thanks Robert
  16. I am finally getting my arty running and have written or modified existing VHDL code and configured it to the FPGA with great success. I am wondering if there are references upon connecting to the arduino usb host shield. I am also wondering how soon the arty A7-100 will be available. Sincerely, DC
  17. Hi, We are going to purchase JTAG-USB Cable to debug our own developed chip. 2 questions here: 1. I assume this JTAG-USB Cable is able to auto-sense my VDD voltage level as long as it is within the range 1.8V ~ 5.0V. Is this correct? 2. We need this JTAG-USB Cable to do some configuration in our chip. Do I use "Digilent Adept Suite" or "Digilent AVR Device Programmer" to generate my JTAG signals/waveforms ? And one request: 1. I need a datasheet of JTAG-USB Cable datasheet if possible. Please advice, thank you. Tifei
  18. Hi All, I'm working on a project that requires me to read a file from a PC (mac, windows, or linux), or external thumb drive onto Xilinx Zybo Z7 board. The communication does not have to be over USB however it does have to be able to read a file either on a USB or a Computer as well as write to that same device. I've looked at several different forums and can't find anything that would make this seem doable. Any help in this matter would be greatly appreciated, thanks for your help. If you could provide an example of a small working project that would be immeasurably helpful.
  19. Hello: I have some question about PC – FPGA Data Transfer,I want to use synchronous FIFO mode to achieve pc to FPGA data transfer: 1:I did not burn the hardware program into the FPGA board, only the upper-computer software to read the data into the chip FIFO, and then use the upper-computer software to read the data from the FIFO.Is this okay?as shown in the Fig 1. 2:Do you have the upper-computer software to achieve pc to FPGA data transfer by synchronous FIFO mode.like Fig 2. My FPGA board is Nexys Video™ FPGA Board. thanks Wang
  20. Is there anyone that has a direct link to download just the USB drivers for the Analog Discovery II (not part of Waveforms 2015)? We are having driver issues on Windows 10. We've tried every other solution that we could find on these forums. (Manually pointing to the drivers, rebooting, reinstalling waveforms including the Adept Runtime, etc.) We are looking for JUST the drivers that someone from tech support can send us while trying to fix this problem.
  21. Hello I just received my Zybo Z7-10 board a few days ago, and have been working on it. I think the USB type A (the USB OTG) is not working. Because I have plugged a simple flash memory with a LED on its back and when I plug it, its LED doesn't turn on. I have another FPGA board "Basys3", and if I plug my flash memory, the back LED on flash memory turns on. I have implemented a Petalinux on the board and it cannot also recognize that USB when I plug it. I have also tested the USB A voltage pins,the voltage between the far right and left pins, and the voltage difference is zero which has to be around 5 volt. Since the warranty time is 30 days, I was wondering if one of the technicians could help me whats going on and if the board is defective. Thank you
  22. Dear MembersI am working on Petalinux 2015.4 and ZedBoard, I am trying to connect a CF Card through USB OTG, but the device doesnot gets registered and won't show up in /dev and I cannot mount it. Kindly help me in this regard.Regard
  23. Hi, I am using windows OS and want to know the use of USB port on Zybo board. I have no idea how it works. Can I able to implement using verilog or I must need Zynq processor? I appreciate if anyone have sample project which will describe the use of USB port using zybo board on windows OS. BR ALI
  24. hello, The following is my description of the problem: I use the FPGA board is nexy Nexys Video A7 board, want to achieve usb and PC information transmission, want to use the synchronization fifo mode,I used FTDI software (FT_Prog.exe) to eeprom into 245fifo mode, but vivado since then show the link is not the device, bit file can not be written. I have two the same board, another board did not eeprom configuration before, vivado can link to the equipment, but after the configuration also appeared in this issue, is not my configuration eeprom there is a problem?Here's my screenshot of the problem。 I hope you will solve this problem for me。 wang

    Impact 13.2

    I am running Impact 13.2 (Windows 64-bit). I have installed the Digilent plugins. When I try to initialize the JTAG chain, I get an error saying that the selected cable is being used by another application. There are no other cables attached to the laptop.
