    Zybo-z7-10 Step File

    Are the step files available for the Zybo-z7? I could not find mechanical drawings anywhere in the resources section or on github. I would like to 3D print up an enclosure for it.

    AXI4 and Vivado ILA

    Hello, My question is related to AXI4 usage in digital image processing. As I am new in image processing with HDL coding, I need to get this valuable answer from you @jpeyron @zygot @JColvin especially. I am using Zybo Z7 and PCAM 5C for my project. As a good start in my opinion, I wanna get digital image from CMOS through D-PHY and MIPI CSI-2 RX. And then, I just wanna scope the digital image bits by using Integrated Logic Analyzer (ILA). For this purpose, do I have to use AXI4 streaming and/or other AXI IPs in my VHDL design? In other words, can I pass the data from CSI-2 interface to ILA directly? If it is possible only with AXI interface, so I will deeply study the AXI4 referance manuals. Many thanks...
  3. Hi, I have been looking for a complete documentation reguarding the zybo z7-20 board but without any success. I need a documentation where i can see also how to set up the I/O in the XDC constraints file. Will be very helpful if you could drop me the link. Also, when i turn the board off and restart it, it reset itself to factory default and i can't really program it permanently, i tried to program it in the three different modality and also entered the memory info but then i do not know what file to upload in the configuration memory device. Thank you
  4. Hello, I am using Vivado 2018.2 i downloaded "Zybo-Z7-20-Pcam-5C-2018.2-*.zip" demo project in original project "part" option is choosen then I created a new vivado project i choose "board" option and i created same block design with "Zybo-Z7-20-Pcam-5C-2018.2-*.zip" demo project. I inserted same IP blocks and made connections. I did synthesis and implementation succesfully but when i exported to SDK and i tried to boot from SD card (i used hello world template) i did not see anything on terminal but when i am trying to export original project to SDK not which i create, then i can see hello world message on Terminal. Why did i not see anything in my project but i saw in original demo project? what could possibly be the problem? Hoping to read from you soon Best regards
  5. Hello Digilent Community, I am working on a image processing project and was wondering if anyone had advice or could point me in the right direction. I have tried following some tutorials and example projects, but I am still trying to wrap my head around Xilinx Vivado and SDK. The project really shouldn't be very difficult, I think I am just missing some information or the best way to go about doing it. For the project I am using the Zybo z7-20 development board and want to save two images to an SD card. The two pictures are black and white frames from a video just seconds apart, so there is only slight change in the frames themselves. I want to compare the two frames and output either a black and white image of the change in pixels or a binary file of '0' being an unchanged pixel and '1' being a change in the pixel. MATLAB has the 'Computer Vision System Toolbox' 'Tracking Cars Using Foreground Detection' Simulink example that is similar to what I want to do on the Zybo z7-20 FPGA. The following figure show the original video (right) with blob detection (the green square) and the binary output image of the change in pixels in the foreground (left). I want to use the Zynq Processor and write C code to do the analysis, but I haven't found a clear way to access the SD card from the Xilinx SDK. The following figure is of my current Block Design with only the Zynq Processor as well as some GPIO to test. I am still researching and looking at examples to compare, but wanted to see if the community had any pointers or if someone has done this before. I am a college student and I have been really interested FPGA's and digital design for the past 6-9 months, but I have mainly written my own Verilog code and haven't worked with block design or running C code on any of my designs. Any comments or suggestions would be great. Thanks!
  6. Hello, I've been to set up a new Zybo board but I'm stuck with a serial port issue. I built my design with the provided board files in Vivado 2017.4. I tried a simple "hello world" in SDK but only got a bunch of unprintable characters. I have Tera Term set up for 115200, 8-bit, 1 stop, no parity. I tried Putty as well and had the same results. I verified the Vivado project is using UART1 MIO48..49. I intermittently can get the correct initialization message from the preloaded QSPI image, but most times it's unprintable characters. I also tried the pre-built Linux from the 2017.4 Zybo Petalinux BSP with the same result. It's definitely booting, but the terminal output is unprintable characters. Other things to note: * I'm running off USB power. I'm plugged directly into my laptop * Sometimes pressing the Reset button makes the PGOOD LED flicker until power cycled Thank you Richard
  7. Hi, I've started using the platform for SDSoC on Zybo-Z7 from https://github.com/Digilent/SDSoC-Zybo-Z7-20/releases. I tried creating a linux based "Hello World" application and was able to successfully run it on the board. I would like to start using GPIO and other peripherals for simple image processing application. When I add #include "xgpio.h" in my main.c file and build (found an online YouTube video demonstration), SDSoC is not able to locate the xgpio.h file. Is there a solution to this? I don't get any error when I choose freeRTOS instead of linux. Thank you!
  8. I've read the Reference Manual for ZyboZ7,it shows the Memory Part of ZyboZ7 is "MT41K256M16HA-125 DDR3L",but when I create a "helloworld" project in Vivado 2018.2,I did not see it at the list. So should I do something to add the suitable memory part in Vivado,or select someone to replace it? I've tried some memory parts,but they all failed,there was nothing displayed in the terminal.
  9. Hi I am trying to run the fsbl and hello world on Zybo-z7-10, but seems like it does not work. When I tried to run the fsbl, it shows the message like this. I build this project step by step learning from a video on youtube, the hardware and software part. I post this link at the bottom. The output in terminal is supposed like this, tell me Boot mode is JTAG, but now it is not. Does anyone know why this happen? If FSBL does not run successfully, the other parts in my project won't work as well since the the clock and interrupts from PS side are not activated. For example, in EnableSampleGenerator, I assign 32 and 1 to GPIO, but when I read from it, they are still 0. Also after I start first DMA transmission, when it finishes, there should be an interrupt, and in the interrupt I start another DMA transmission. Now seems like the interrupt never happens, so I seriously doubt the FSBL does not run properly. Thanks a lot in int main()
  10. hello, can I change the reference clock for Dynamic Clock Generator IP core? Which frequency do I have to provide for REF_CLK_I?
  11. Hi all, I have a Zybo and have been using it successfully for a variety of HDMI / VGA video projects. I'd like to have a go at interfacing a Raspberry Pi V2 camera. I understand that I need to implement a MIPI CSI-2 receiver in VHDL and I have a reasonable idea of how to proceed. This may take a bit of effort, but that's part of the fun! However, what I'm not sure about is whether I can specify the appropriate 1.2v IO Standard that's required on the Zybo board via the high speed PMOD ports? Or, will I need to buy one of the newer Zybo-Z7 boards? I realise that the newer Zybo-Z7 boards have a 2 lane MIPI connector (which is very convenient), so I'm assuming that the connected Zynq pins can run in the appropriate 1.2v differential IO Standard. But for this to work does the newer Zybo-Z7 have a specific 1.2v VCC supply to facilitate this? (that perhaps the Zybo doesn't have) I will probably upgrade to the newer board anyway, but would like to understand if this is possible on the older Zybo. Many thanks!
  12. Hi, today I received a ZYBO Z7-20, including a voucher for SDSoC. In SDSoc there is only a hardware platform for ZYBO available, and I couldn't find one on Xilinx' or digilent's websites. In a parallel thread here i found a reference to UG1146, which I am reading now. As I am quite new to SDSoC development, this will be a good experience. Nevertheless I want to ask, is there a hardware platform for ZYBO Z7-20 available anywhere? Or will there be? Regards, Dieter
