  1. Hi Team, I'm working on zybo z7010 evaluation board, now i'm trying to program the qspi flash through vivado lab edition tool 2020.3. 1. I have created the bitstream for zybo board in vivado 2020.2 and application project in vitis 2020.2. 2. In vivado lab edition tool i have generated the memory configuration file 3. I have added that configuration file and tried to program the flash device(Spansion s25fl128s-3.3v-qspi-x1-single) 4. I can able to program the fpga, and my current boot mode is JTAG. 5. Every time i'm getting the error message as follows Problem in Initializin
  2. I am new to FPGA design . I have bought Zybo Z7-10 board and tried the LED demo given in this link" https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-led-demo/start" but i have the following questions about the demo . 1. The board has only 4 LED and i have one PMOD with 8 LED . How to map the IP to this two different LEDS ? 2. Also the T20 pin given in the example serves for HDMI port in the xdc file , then how we can map the same in LED pins? 3. In 2019.2 version i am not able to find launch the SDK option then how to execute the same example.
  3. Hello, I am trying to send a very small amount of information (8-bit numbers) from my PC to my Zybo Z7-10 over a USB connection using UART. I understand that the best way to do this is using the block diagram and then the SDK, however I can't find any tutorials or walkthroughs that use USB, not HDMI or Ethernet. I know it is possible to use the on-board USB connection, though. Is there a tutorial that I have missed? What is the best way to go about doing this? The hello world, etc. tutorials don't show how to actually make that UART connection, just how to deploy to a board over USB. Th
  4. hi all, i want want to measure a voltage with the zybo and display the measured values on a screen via hdmi output. i used the hdmi passthrough projent as a start and got that working fine. know when i added the adc in vivado i get the error that the Vccs on bank 35 are incompatibele because the hdmi used 3.3V and the adc uses 1.8V. but when i look in the schematic under synthesis and look and the i/o ports i see that the hdmi aslo uses 1.8V. so why is it a problem when the adc needs 1.8V but when the hdmi needs 1.8V it works just fine.
  5. Hi everyone, I am currently working with a Zybo Z7010 board on Vivado 2018.3 and am trying to implement a memory access in both reading and writing modes. More precisely, I'd like to enable the user to enter a number of coordinates that define a random waveform (sine table...) and to store it somewhere so that the PL can access it in reading mode and display it through a DAC. Please note that it is essential that the reading process is fast for further applications. Now, have been reading many things but I'm a little confused about the "different types of memories that exist". I
  6. Hi I'm newbie for fpga. I want to connect my zybo Z7 device to matlab simulink. I follow these workflow.(https://se.mathworks.com/help/hdlcoder/examples/define-and-register-custom-board-and-reference-design-for-zynq-workflow.html) During 10th step, error message appears. How I can solve this problem? Error using codertarget.zynq.internal.LinuxShell/setupZynqHardware (line 543) Cannot connect to "Zynq hardware". Details: Could not connect to the hardware over Serial Port. Check that USB cable is plugged into 'USB-to-UART' port of the hardware and the power switch is turned o
  7. I am working on the Zybo Z7-10 board. My goal is to determine the position and orientation of the FPGA in space at any given instance. For that, I am using a PmodACL2 and PmodGYRO. Now, I need to integrate the accelerations and angular velocities. How do I measure the time at which the Pmods are giving me the data?
  8. Hi, I have a Zybo Z7-10 board which has 5 pmod ports on it. However, in the block design, I can see only four of them, v.i.z. JA, JC, JD, and JE. What do I do if I want to use the JF port?
  9. I recently started working on the zybo z7-10 board. I have two pmods - the PmodGPS and the PmodCON3. Both of these pmods have 6 pins each and I want to connect both of these pmods to the same port on the fpga. However, I could not connect the PmodGPIO_0 and the PmodGPS_0 blocks to the same port in my Block Design in Vivado. Is there any way to do this?
  10. I'm working with the HDMI ports on a Zybo Z7-10 development board, and I'm trying to set it up as an HDMI passthrough. As in, the HDMI input signal would simply be fed into the HDMI output port without any processing in between. I will eventually be filtering the video signal but I'm using this passthrough as a starting point. The HDMI hardware on my Zybo, as well as my HDMI source and output screen, are all confirmed working because I've been able to run Digilent's HDMI demo on it. I'm using Vivado 2017.3 I was able to get my block design started by following this forum post, replacing t
