  1. Hi all, I'm working on a video streming project with a zedboard and an ov7670 camera module. I found a similar project online, made by Mike Field, and I was able to make it work. But I want to buid the project using custom IP's. and I found this project: https://lauri.xn--vsandi-pxa.com/hdl/zynq/zybo-ov7670-to-vga.html I used the same (working) VHDL code, the same XDC file, the same setup, and followed his instructions, but for some reason, whenever I try to create custom IP's (with or without AXI), I can't make it work, and the monitor says "no signal". Can
  2. Hello everyone! I'm not sure whether this forum is the right place to ask this question but still. I have connected a low-cost OV7670 camera to this Digilent example: https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-hdmi-demo/start?redirect=1 Here is what I've done. I took the OV7670 - > AXI4Stream core from here (link below) and attached it instead of HDMI input. I changed this module to have not 32 bit RGBA output but 24 bit RGB input https://lauri.xn--vsandi-pxa.com/hdl/zynq/xilinx-video-capture.html and also I took the OV7670 Contro
  3. Greetings everyone, This is the first ever post of a beginner who has set on the path to learn embedded systems. Please forgive me if haven't followed rules of posting. I took the embedded system plunge few weeks back. Bought a strong laptop, a Zybo board, OV7670 camera, installed Vivado. Read online tutorials like 'blinking LEDs' and 'HDMI-to-VGA out' (and the others ones in Zynq Book) to get myself accustomed with Vivado etc. [Abbreviations in the text: PS= Processing System, PL= Programmable Logic] I have been visiting a blog lately and have found that quite helpful. A couple of
  4. Hi JColvin, We used zybo for our board prototype integrated with OV7670 Camera. every time I run it. I have a warning like this: INFO: [Labtools 27-1434] Device xc7z010 (JTAG device index = 1) is programmed with a design that has no supported debug core(s) in it. WARNING: [Labtools 27-3123] The debug hub core was not detected at User Scan Chain 1 or 3. Resolution: 1. Make sure the clock connected to the debug hub (dbg_hub) core is a free running clock and is active OR 2. Manually launch hw_server with -e "set xsdb-user-bscan <C_USER_SCAN_CHAIN scan_chain_number>"
