  1. Hello, We are trying to generate the SPI protocols signals from the Zybo-Z710 board, which uses Zynq-7000 SoC. Since, the PS section of the chip contains two SPI modules. Can anyone tells me the procedure for activating the SPI line inside the PS. I want to use this SPI lines to transfer data and provide control to the another module. Thanks AMOL
  2. Is there a way to just input a voltage and read it through the terminal using the XADC Header on the Zynq 7000 Zedboard? If so can this be done using the VP VN pins?
  3. Hi, I've recently bought a Zybo z7010 board and had a go at running the example given here: https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-getting-started-with-zynq/start#tutorial The bitstream was generated successfully as expected but when I load the application on to the Zynq PS, I observe that: None of the LEDs are lit when the corresponding buttons are flicked. No message is displayed on the UART console when any of the switches are pressed. Can anyone provide some hints on how would I go about debugging the issue? Some info w.r.t
  4. Hi, I'm trying to measure an external Voltage connected to the AUX0 pin of the XADC header using Zedboard .While measuring the output I find that the voltage is shows higher value by factor 3 or even 4 of the input differential voltage applied. I'm unable to figure out why this is happening. C code file is attached also. I have followed the following thread while performing my project too https://forum.digilentinc.com/topic/4311-zedboard-zynq-7000-xadc-header/?page=0#comment-16891 I have connected AUXP0 to 0.2 V and AUXN0 to GND . Could someone help on this??

    Delay

    Hi all, How to implent delay in verilog code? I want to run a led blink code with one second delay using zynq zybo-7-z10 Thanks in advance
  6. Hello, I was earlier able to flash LEDs on the Zybo 7010 board following the tutorials. However, I am currently trying to use the Zybo 7010 to flash LEDs which are external to the board. What I am looking at here is getting a constant voltage supply from one of the ports (maybe preferably the Xadc) to power the external LED circuit. I am having trouble getting a block design using the xadc_wiz_0 ip and the axi gpio with the zynq 7000 processor. Any information on this is greatly appreciated.
  7. I have an arty z7 FPGA an am working on a petalinux project. I am able to config and build my project. But when i boot it it says bitstream is not compatible with the target. What does that mean? any suggestions? I exported the HDF from vivado and in project settings the target device is same as the one i am using.
  8. (Not sure if this thread should go in Embedded Linux. If so, please feel free to move it) Hello everyone. I'm having quite a hard time trying to make these two (XADC and Xillybus/Xillinux) work together and I was hoping someone here could lend me a hand. Basically, what I am trying to achieve is: I'll input some analog signals to VP/VN, Vaux0 and Vaux8 to the XADC. I want it to convert them and that conversion to be written to a FIFO that can be read by Xillybus, which will make it available for me in Xillinux (so with a simple command I can dump the conversion into a file). A more v
  9. Hi I am trying to use the Zedboard zynq 7000 external mux and I was wondering if anyone could provide me with some detailed information or an overview of what exactly the purpose is of the external mux and how it functions. Thanks

    Why i am getting this error ? By using the Zybo Board "ERROR: [Labtools 27-2149] File D:/pallavi/Vivado Prgrms/zybo_verifyleds/zybo_verifyleds.runs/impl_1/verifyleds.bit not found. Check file name and file permissions. ERROR: [Labtools 27-2163] Unable to read xicom bitstream D:/pallavi/Vivado Prgrms/zybo_verifyleds/zybo_verifyleds.runs/impl_1/verifyleds.bit"
  11. Good afternoon! I am trying to get USB interfacing to work on the Zybo. Because I eventually want to build my own board, I am familiarizing myself with all parts of a functional toolchain. My toolchain looks like this: Generate hardware platform with Vivado 2016.2, using Digilent HW Platform Guide as a reference. Exporting hardware from Vivado. (Note: Hello World SDK project runs successfully from this HW design). Use Petalinux 2016.2 to create a project, load in files as necessary, and generate boot image, as described in UG1144. (Using hdf and bit generated with Vivado, FSBL
