  1. Hello everybody, I am working on Image processing pipeline using zybo and Pcam. I have reference hardware design and petalinux project from v2017.4 by Digilent Hardware Design : https://github.com/Digilent/Zybo-Z7-20-base-linux Petalinux project : https://github.com/Digilent/Petalinux-Zybo-Z7-20 I have tested this project in v2017.4 and it works perfectly well. I am trying recreate it using only Xilinx IP cores and xilinx linux kernel. I notice that the petalinux project uses Digilent's kernel for drivers and not the xilinx kernel. Also another difference in the design
  2. Hello everybody, I am building a Petalinux v2019.1 project to save images using v4l2 driver. The pipeline is simple which includes Pcam-> MIPI csi2 rx subsystem -> sensor Demosaic -> video frame buffer write When I use v4l2-ctl -d /dev/video0 --set-fmt-video=widhth=1280,height=720,pixelformat=RGB24 --stream-mmap --stream-count=1 --stream-to = test.raw to save the Image. test.raw file is saved however it is of size zero. When asked on forums it turned out that there is issue with output format. According to Pcam reference manual it supports RAW10, RGB565 , CCIR656, YUV42
  3. Hi, I am following the ZedBoard FMC Pcam Adapter One to Four Camera Demo (https://reference.digilentinc.com/learn/programmable-logic/tutorials/zedboard-fmc-pcam-adapter-demo/start) and I am able to stream the video of all 4 cameras as of now . Is there a way to save the video that are being streamed or even saving a single frame as image ? I am using Vivado v2019.1 and Xilinx SDK 2019.1 Thank you
  4. Hi. I've tried to operate Pcam-5c at Zybo-Z7-zynq7020 using Xilinx Vivado tool. I refered to source code for Pcam-5c posted on github( https://github.com/Digilent/Zybo-Z7-20-pcam-5c/releases ). It operated successfully but I want to try again using other camera module instead of Pcam-5c. I have some problems in MIPI formatting data because Zybo7020 & Pcam-5c use RAW10 data but my camera module use RAW12 data. How can I use RAW12 format with Zybo-Z7-20 ?
  5. Hi! I'm using a PCAM5C with Zybo Z720 revision platform on SDSoC. Right now I'm using filter2D for PCam5C and I've seen that the default format is a multi-planar, two-plane version of the YUV 4:2:2 format, and when they apply the filter2d they just use the Y plane. I wanted to know if anyone could help me with changing this format into RGB because I want to use in the filter2d.cpp the cvtColor to transform the RGB 3channels into 1 grayscale. Or if maybe there's a conversion between YUV4:2:2 and RGB by using the two planes? Thanks so much!!
