  1. 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: CSI-2 Camera: DLP 2000 RGB - projector: HDMI projector: Display : 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....................
  2. Hello, everyone! I am now working on a project which have an action cam connected to HDMI Input and then filtered with HLS Video Library and then i wanted to use the Zybo as a generic webcam to the pc host. What I wanted to ask is how do I configure my UVC linux kernel so that it receives the video output from my PL that I connect to my PS through AXI Mem Interconnect, and then ready to use as USB Webcam? Also, can I run an OpenCV apps which generated from Vivado SDSoC and output the video to the uvc? Any helps and hints appreciated, Thanks!

    Linux Gadget

    Hi all, I'm new in this world and I hope someone could help me in this issue I'm working on a project in the Uniersity where I would like to use the Zedboard as UVC device to stream video from FPGA to the host. I'm able to build, configure and run the kernel from SD but I'm having some problem to connect the Zedboard as peripheral mode and to detect it as UVC gadget. In particular I've configured the kernel to act in peripheral mode following this instruction : To let the Zedboard act as gadget I started from this guide and then I configured the kernel for USB Webcam gadget enabling these option: <*> USB functions configurable through configfs [*] USB Webcam function <*> USB Gadget Drivers (USB Webcam Gadget) At the end of building kernel process I have the g_webcam.ko and the libcomposite.ko modules. After that I boot the linux on the Zedboard and I tried to load the modules with insmod command but having this issue: Welcome to Linaro 12.11 (GNU/Linux 4.9.0-xilinx-25595-g68e6869-dirty armv7l) * Documentation: [email protected]:~# cd / [email protected]:/# ls bin dev home lost+found mnt proc run selinux sys usr boot etc lib media opt root sbin srv tmp var [email protected]:/# cd home [email protected]:/home# cd linaro [email protected]:/home/linaro# ls examples.desktop g_webcam.ko g_zero.ko libcomposite.ko [email protected]:/home/linaro# insmod libcomposite.ko [email protected]:/home/linaro# insmod g_webcam.ko insmod: error inserting 'g_webcam.ko': -1 Unknown symbol in module [email protected]:/home/linaro# I also tried to connect the Zedboard to a Windows host and obviously nothing succeed. Could someone help me please? Thanks. -Mattia
