    USB audio on PYNQ-Z1

    Hi there, I am pretty new to using the pynq-z1 board. I wish to do some audio recording via a usb microphone! I am struggling with doing this successfully, is anyone able to help me with this? I am getting "no soundcards found" when issuing alsa commands arecord -l and aplay -l. I understand pynq -z1 receives audio samples as PWM or PDM, but im not sure exactly what that means in terms of linux drivers available. any help would be appreciated! Thanks
  2. We are using the PYNQ-Z1 for the development of a new product and need the supporting hardware design files. I have not been able to find the BOM, or electronic version of the schematics or PWB, on the website. It appears the design was done in Altium, which is what we use. Is it possible to download these files or have them sent to us?
  3. Hello I'm using PYNQ-Z1 board. I am trying to receive CAN traffic with PmodCAN on the board. Here is my Block Design. Then, Generate Bitstream was successful. (But some warnings appeared and the messages are like Generate_Bitstream_messagex.png) I did Export Hardwear and Launch SDK. When I created the Hello world project in SDK and compiled it, there was no problem. However, as soon as I executed Program FPGA, the following error message appeared. How can I fix this error? ---------------------------------------------------------
  4. I'm attempting to use all 6 single ended ADC channels of the PYNQ-Z1 board with DRP enabled and with continuous sequencing (see attached configuration). According to the 7-series XADC guide UG480 on page 72, "When XADC is being operated in a sequence mode, you can identify the channel being converted by monitoring the channel address (CHANNEL[4:0]) logic outputs. The multiplexer channel address of the channel being converted is updated on these logic outputs when BUSY transitions Low at the end of the conversion phase." But the output of the channel (channel_out) is always zero, which I've
  5. Hi guys, I've just bought a Pynq board. Could anyone help and give the main steps to follow to add a new PMOD device to the default overlay? I'd like to add the DA3 PMOD DAC that is currently missing. Many thanks!
  6. 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 <--- I checked in the Windows Device Manager. - Speed (baud rate) : 115200 - Data bits : 8 - Stop bits : 1 - Parity : None - Control flow : None But when I cl
  7. 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
  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. today I received a MicroSD memory card (8GB) from Digilent (https://store.digilentinc.com/pynq-version-8gb-microsd-card-with-adapter/) 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 a
  10. Hello everybody, Just received my Pynq-z1 board from the FedEx guy! Couldn't wait to check things out! Regards, Tim
  11. 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:
