  1. Hello all, I am going to apologize in advance for this question. I have been trying to figure out how to even get started with respect to creating a web server in Linux. I found this example which is great, however, it's for bare-metal application: https://reference.digilentinc.com/reference/add-ons/dmm-shield/webserverdemouserguide?_ga=2.161769276.1628826370.1603404428-96488038.1600272185 I found links that relate to using busybox/http but I could not find how my c application would interact with the webpage. I also need to transfer large data sets. I would like to
  2. That did the trick. I really appreciate your help!
  3. I am going through UG585 document and trying to understand the formulas for the can bus baud rate. I am using the example from SDK (xcanps_intr_example). I am trying to understand how they are arriving at those numbers. Ultimately I would like to set up the baud rate at 1 megabit per second. /* * The Baud Rate Prescaler Register (BRPR) and Bit Timing Register (BTR) * are setup such that CAN baud rate equals 40Kbps, assuming that the * the CAN clock is 24MHz. The user needs to modify these values based on * the desired baud rate and the CAN clock frequency. For m

    CAN Bus

    I am using zybo Z7-7020 version and trying to use the CAN bus on the PS side. I am enabling the EMIO such that the TX and RX are landing on the PMOD connector (JC). I have verified that the bare metal application is working loopback mode. With an external CAN bus transceiver wired between the zybo board and another CAN bus node. The other node is sending messages and the zybo board is just waiting to receive the message. In Vivado I have configured the CAN CLK as such please refer to the attached. I have change the SDK interrupt example not to send out any CAN bus messages and also c
  5. Hello everyone, I am new to Petalinux. I have couple of questions. I am using PetaLinux SDK version "2018.3 when I do petalinux-config --get-hw-description=../ i get the following: WARNING: Your PetaLinux project was last modified by PetaLinux SDK version "2017.4", WARNING: however, you are using PetaLinux SDK version "2018.3". Please input "y" to continue. Otherwise it will exit![n]y When config manager comes up I hit ESC then this prints out INFO: Getting hardware description...

  6. I am looking for tutorial that guides through the entire flow. Meaning, create a vivado project then create a linux image based on that hardware design. I am trying to figure how to write an application that would access my custom HDL module through Linux. I have already verified that my custom HDL module works through the AXI lite bus interface. I created a bare metal application to test my custom HDL module and everything works as I expect it. So, the next step would be doing the same through a Linux application. Hope that makes sense. Also, I am currently working with vivado within
