    Basys3 USB power not working

    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
  2. 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.
  3. Good day everyone! I need help on programming the Nexys 3 using a USB memory stick. Here is what I tried so far: 1. Save a single .bit file to a USB memory stick. I have tried my own .bit files as well as the Digilent's Built-In Self Test. I have also tried two USB flash drives. 2. Connect two jumpers on the mode switches. I have also tried none and mode 0 only. 3. I then attached the USB flash drive to the Nexys 3 and press the reset button. But unfortunately the bit file does not get programmed to the FPGA. The <busy> LED beside the USB port on the Nexys 3 is forever blinking at a slow rate. Does anyone tried configuring the Nexys 3 using a USB flash drive? Thank you. Note: I tried it on another Nexys 3 board but also fails to load the bit file. Regards, Nico C.

    Cmod S7 and USB cable issue

    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.

    USB CAM INTERFACING TO ZYBO

    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!
  6. Regarding: Zybot Project I am having an issue getting the USB WIFI Adapter to successfully connect to the internet. What is working: 1) Micro SD card Prepared for Boot on Zybo 2) Successfully able to boot and login to linaro 3) Connected a 4:1 USB hub to the USB port on Zybo and all ports are working - Tested this by connecting 1 mouse on all 4 ports, (one at a time) and the mouse works on all 4 ports 4) Camera is working fine, (motion is installed, server scripts copied to init.d and permissions changed) 5) Able to view Camera feed through IP Address but that address is issued through eth0 NOT wlan0 Hardware: 1) RA Link RT5370 USB Wi-Fi Adapter - linked for image - This adapter works flawlessly when I connect it to my PC. 2) Zybo, powered via 5V DC wall-wart power supply 3) Logitech C120 Webcam Note: Instead of connecting the zybo via HDMI, I have connected it to my router via Ethernet and am using SSH to send instructions In order to illustrate the problem: (lets look at the responses from terminal....) 1) When I type 'lsusb' (utility for displaying information about USB buses in the system) --> I get screenshot 1 - As you can see here, the WIFI adapter is detected fine 2) When I type 'ifconfig' --> I get screenshot 2 3) When I type 'lsmod' --> I get screenshot 3 - No kernel modules are installed 4) when I type 'sudo nano /etc/network/interfaces' --> I get screenshot 4 - which is detailing how I want the network interfaces to be set up 5) when I type 'sudo nano /etc/wpa_supplicant/wpa_supplicant.conf' --> I get screenshot 5 - Which is detailing the credentials of my network (you can see my password, it doesn't bother me) ISSUE: I am able to stream from the camera successfully through the wired internet connection (screenshot 2 shows that I have a valid IP address) The problem is getting the USB Wi-Fi Adapter to show up in 'ifconfig' so that I can use it for streaming. Doing so will allow me to detach the Zybo from the router's Ethernet connection and use it cord free on a battery pack. Please tell me how to set up RT5370 USB Wi-Fi properly on Linaro (for Zybo) and also connect to any network of choice
  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.

    Atlys USB JTAG problem with VirtualBox

    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

    Reference design for mouse overlay

    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
  11. 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
  12. 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....................

    Parallel FPGA JTAG programming

    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!
  14. 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.
  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

    ARDUINO USB HOST SHIELD And Other Questions

    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

    Read/Write over USB Zybo Z7

    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.

    JTAG-USB Question

    I am interfacing between a USB IC (a FT2232H FTDI chip) and a EEPROM IC (a 93AA56BT). To make the FTDI chip recognizable by Xilinx tools I need licensed Digilent Serial Numbers. How can I get a licensed serial number file to enable a USB-JTAG FTDI interface? Are these licenses keyed specifically to your chips? How can I enable a JTAG-USB FTDI interface?

    USB HID -> PS/2 PMOD board ?

    Hi Digilent staff, and fellow forum members, Just wondering if you guys had considered making a USB HID -> PS/2 PMOD board? I was thinking of something like the circuit on the Nexys 3,4 boards which uses a PIC to convert a USB keyboard to PS/2 compatible signals. Would be handy for using newer USB keyboards/mice on PMOD socket equipped FPGA boards. PS/2 devices are becoming harder to find brand new. I (for one) would be interested in a few. Kind regards, Leslie

    PC – FPGA Data Transfer

    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
  22. 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
  23. My Analog Discovery 2 was very sensitive to movement, with Waveforms reporting the connection lost at the slightest bump. Merely manipulating the flywire leads was enough to cause a disconnect. I determined that the plug on the USB cable that came with the AD2 was not able to seat completely into the AD2's USB jack. While looking through the top of the AD2's enclosure at the USB jack, I observed that the two metal "spring fingers" atop the USB plug were not inserting deeply enough into the jack to permit them to raise and latch into their corresponding holes in the top of the jack. After disassembling the AD2's enclosure, I used some (mechanical) files and an X-Acto knife to enlarge the enclosure's USB port hole so the entire USB plug can pass through (photo attached). With the enclosure assembled, the USB plug now seats completely into the AD2's USB jack. I can see that the two metal "spring fingers" advance into their intended positions and raise up into the jack's holes. Waveforms has yet to report a disconnect during my experiments with wiggling the USB cable.
  24. 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
