Hi! I would like to do a project similar to this one but I have been unable to find any resources explaining how I can write applications in petalinux. Could you please point me to some of the resources such as videos or books or blogs that explain how I can write my own petalinux applications.
I used Vivado to build the RTL project. I did use the SDK to write the application for Linux, however I relied on the PetaLinux build tools for building the OS and compiling the application software.
Great work !!! I try to implement these example project that you share for my zynq board. Thank you so much by the way. Do you suggest that in these applications do we need to have a HD camera which has HDMI port especially(as you did). Can we implement this with USB port ? And working with petaLinux is different than normal linux i am very new at this :'(
impressive!!! I am working on an image processing project using zedboard, where I need some guidance. I want to read some images from the SD card, do some processing on the PL and finally display the output through HDMI. We need some help with the design flow, if possible. Thanks in advance.
Hmmm. Never had a SD card reader, so I never got a chance to do a project with it. But, it should straight forward if you have experience with Linux, building PetaLinux, and RTL development with Vivado. With the Zynq, the SD controller can be enabled by configuring the PS. The hardware description file generated should be recognizable by the petalinux-config tools. Once you have the OS running on the hardware, I want to say that you should be able to mount the SD drive on to a folder. As for the HDMI, I suggest looking into some of the Digilent examples. In the project shown in the video, I am actually using their core to access the VGA. However, it can be configured to drive the HDMI interface. You can follow my project if need help utilizing peripherals from user space. I hope this helps!!! Contact me through email if you need further assistance.
Hello Andrew, i am working with traffic sign board detection application developed using opencv (it was a desktop application).Now i want to port it to Zynq .Can u guide me how to start with as i am new to FPGA
+rushi qian Hello Rushi! By installation, are you referring to the entire process of building, linking, and ensuring the libraries are accessible on Linux? What I like to do is build the OpenCV libraries as static libraries. You can do this with CMake using the OpenCV list file. Of course, you need to make sure you are using the same compiler you use to build any other application for the ARMv7 architecture. Then, you can link to those libraries in your application!! No need to worry about keeping track of .so files!! Hope this helps!!!
I Need an answer to a problem I faced when trying to use a Zybo FPGA... I recently bought a Zybo FPGA with its Voucher to get the license of " Vivado System Edition" that allows me to use Vivado HLS Then I signed in , in the Xilinx website and downloaded the Vivado from the xilinx website with my own Xilinx account, then I installed Vivado System Edition and opened the Licence Manager to get my " Vivado System Edition " license with my own Voucher. The problem is that when I use my voucher code, I don't get the " Vivado System Edition" in the list of licenses ... so what should I do to get the Vivado System Edition license ?

thats great work! could you tell me what software you used to program the zybo? did you use vivado or maybe SDSoc?

No problem! ^_^
I reread your message and I'm confused. I used a USB camera in the video.

Do you use OpenCV2.x or 3.x ?
I really like the video ,can you tell me how you install opencv?
