  1. So I want to connect the PYNQ-Z1 board directly by opening a USB serial terminal. The PYNQ-Z1 board is bought with the pre-loaded image in the SD card. The board setup is the following: - Connected with external power adapter - Port J14 UART is connected to USB port on the laptop I waited until the system is booted and ready to use, opened the PuTTy on laptop, set: - Serial port: COM10 - Speed (baud rate) : 115200 - Data bits : 8 - Stop bits : 1 - Parity : None - Control flow : None But when I clicked open, nothing happened on the screen. Is there any required step before using the serial port on the PYNQ-Z1 board?
  2. Hello, I am trying to make an HDMI passthrough application on the PYNQ-Z1 board using the dvi2rgb(1.9) and rgb2dvi (1.4) IP blocks from this github repo. Here are the technical details of my tools: Vivado 2018.2 PYNQ-Z1 board (part xc7z020clg400 - 1) (Got the board file I’m using in vivado from this webpage Dvi2rgb v1.9 Rgb2dvi v1.4 Here are some images of my project: Constraints Block Diagram clock wizard settings dvi2rgb rgb2dvi Long story short, the application doesn’t work when I use it between my laptop (Lenovo Z710 Ideapad running Windows 8.1) and my TV (Toshiba 49L420U with dimensions 1920x1080) After consulting a lot of posts on this website, especially this one and this one, I’m still not sure about what the magic formula is to get these IP blocks to work. The posts don't seem to be addressing the problems I'm having with this design, but rather making changes to the specific implementation of the project. They were all older versions of the IP blocks and vivado, and they were using different boards, so those factors may have contributed to why those examples didn't work for me. I’ve reduced my critical warnings down to three, which are the following: 1.) Timing: i get the following timing warnings after running implementation 2.) Set_property expects at least one object a. I get two of these, for the two constraints listed at the very bottom of the constraints I showed in the first image above. How can I write these constrains such that Vivado will recognize them and won't throw a warning? I read from the posts I mentioned earlier that timing requirements may throw a critical warning but the design will work anyway, but I haven't had the same fortune. So has anybody here gotten their design to fit timing and create a working project? If so I'd love to know how, and if you failed timing but still got the project to work, what did your timing analysis look like? As can be seen in the block diagram, I pulled the aPixelClkLockd signal out to an LED, which is an active high signal. But I haven't gotten this signal to be high, so obviously that's a problem. If the clock recovery block in the dvi2rgb IP can't get a lock on the incoming clock signal, does this mean that the project is not properly constrained, or does this mean that the IP block won't work with my laptop? I read a lot about DDR signals, and I believe that I set those up correctly in my block diagram and constraints file. But I didn't understand what hpd signals did, and I don't know which block diagram they are supposed to come from. Any help here would be greatly appreciated! Best, Ben
  3. 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.
  4. today I received a MicroSD memory card (8GB) from Digilent ( sent separately after the PYNQ-Z1 board had already arrived. I need the manufacturer/brand name and type to download the Windows 10 drivers for that card (better a weblink with those drivers). When I insert the card in its adapter and plug it in in my Windows Laptop, nothing happens. With those drivers I should be able to verify first whether that memory board is empty. If so I can burn the necessary image. Your prompt response is highly appreciated. Thanks. (that the DONE LED does not light up in the procedure described below is an indication that the bitstream could not be loaded) -- (BEFORE:) Hi, the memory card just arrived, but see below how far the PYNQ-Z1 board with the memory (Micro SD) card inserted in it comes. Is the memory card you just sent me empty, ie, do I need to download the PYNQ-Z1 v2.1 image and burn it myself ?, I thought the memory card from DIgilent would come ready ... Thanks. Looking forward to hearing from you soon. PS (cf also attached board layout) SETUP: JP4 to SD, JP5 to USB, Micro SD card inserted, (J14) USB cable-connected to Windows 10 Laptop, (J13) Ethernet cable connected to Xfinity/comcast gateway where also Laptop is connected Following the link below, when I turn on the board, the RED LED12 comes on immediately. Then LEDs LD8 and LD9 flash and stay flashing "forever". LED LD12 does not light up.... (in chrome browser: http://pynq:9090/ -> This site can't be reached) ... Turning On the PYNQ-Z1 As indicated in step 6 of Board Setup, slide the power switch to the ON position to turn on the board. The Red LD13 LED will come on immediately to confirm that the board has power. After a few seconds, the Yellow/Green LD12 / Done LED will light up to show that the Zynq® device is operational. After a minute you should see two Blue LD4 & LD5 LEDs and four Yellow/Green LD0-LD3 LEDs flash simultaneously. The Blue LD4-LD5 LEDs will then turn on and off while the Yellow/Green LD0-LD3 LEDs remain on. The system is now booted and ready for use.

    Hello everybody, Just received my Pynq-z1 board from the FedEx guy! Couldn't wait to check things out! Regards, Tim
  6. Hello, I've recently purchased a PYNQ-Z1 dev board and am working to follow the examples in the Adam's MicroZed Chronicles. I'm able to successfully create the reference design in Vivado consisting of only ZYNQ PS, generate bitstream, Export HW Design and also create software projects that run on the target device in the SDK via JTAG. When attempting to create the boot image and flash, I've been unable to get the anywhere via QSPI or by placing the .bin file directly on the SD card and using the SD boot option switch. Here are the steps I've taken thus far: Create new Vivado Design project referencing the Digilent Arty-Z7-20 Board Added the ZYNQ PS Connected M_AXI_GP0_ACLK to FCLK_CLK0 and fast foward....generated Bitstream Exported HW Design Create Sample Hello World Project in SDK (tested successfully and runs perfectly via JTAG) Generate FSBL Create Boot Image - Added elf bootloader from FSBL - Added bitstream from HW Export -- This generates the bin file used to program flash in the next step Program Flash - Selected the HW Platform Exported from Vivado - Used Image file created above - No Offset - Flash Type qspi_single Flash programming completes successfully. I select QSPI, power cycle the board and fail to get the done LED on the board indicating that the FPGA bitstream has been downloaded. I place the same bitfile named boot.bin on the SD card and get the same result. Nothing. Any suggestions? Is there some strange delta w/ the Digilent board I'm using that I don't know about. Additionally, the example bin file provided by Digilent works perfectly.
