  1. Hi, I am new to the Zybo Z7 platform. I watched a video from Xilinx on using Xilinx SDK to run a simple "Hello World" program on the on-board processor. Following the steps shown in the video would however not work, as SDK doesn't recognize the Zybo Z7 board (Zybo-Z7-20). I followed the steps shown in the tutorial here and was able to get the "Hello World" displayed on the SDK terminal. Here are my questions: 1. Do we always have to "Export Hardware" and launch SDK from Vivado? In other words, can we directly launch SDK, create a new application project and somehow select the right hardware platform for the Zybo Z7 board? Are there any files we could copy to make SDK understand the Zybo Z7 board? 2. After writing the C code that is to be executed on the PS, the tutorial asks us to program the FPGA first and then run the application code. However, the Xilinx video doesn't involve the programming FPGA step. Can someone please explain why it is required in one case and not required in the other? Thanks in advance.
  2. Hello, I am trying to display text on an image using the libraries provided . I am able to load the image and print text separately but when an image is loaded and i try to display text on it, it does not seem to print. How can i print text on a image loaded from sd card present in Pmod MTDS. With Regards, Ajs
  3. Greetings all, Usually, the default uart for xilinx sdk is ps7_uart1. But I want to use axi uartlite block as my stdin and stdout since I want to redirect the xil_printf statements to uartlite rx pin. Is that possible to change the stdin and stdout to axi uartlite and still view the printf statements in the terminal output???
  4. getting a error while i am trying to program FPGA (zybo) with Pmod:ACL in Xilinx sdk.
  5. I am fighting to get any one of 5 different simple ZYBO demos to work. At all. I can download bitfiles with my own Verilog code and blink, or scan, or pulsate the LEDs, and get behaviour changes based on buttons and switches ... so I know the board works, but nothing I do with the with the processor core (PS block) works. I am here looking for information on how to get some kind of information out of the board so I can figure out what's going on. The demo I am working on now is this one: https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-getting-started-with-zynq/start It does not ask for a Debug Configuration, or a Run Configuration, ... just the Run as -> Launch on hardware. There is a terminal setup at the end of that tutorial. Frankly I don't know why a separate console is needed since SDK has a "Console" and an "SDK Terminal". Nonetheless, I tried 'screen' and putty as others recommended, then minicom as well ... all I ever see is a blank screen. I don't know what I should expect to see really. I followed the tutorial to the letter. The only indication I get that things are connected at all is that with screen and putty, when I hit any key, I see ZYBO's TX LED flash once. I am running Ubuntu 16.04 and Vivado 2016.4. I have lots of Xilinx experience, but all command line and not with SDK (so telling me "It's just like ISE but ..." will make me cry. I just want something out of the console. Smoke would be nice. If it helps, I do see this in XSCT Console: Downloading Program -- /-----/projects/zybo/ZYBO_getting_started/ZYBO_getting_started.sdk/getting_started_with_ZYBO2/Debug/getting_started_with_ZYBO2.elf section, .text: 0x00100000 - 0x00102467 section, .init: 0x00102468 - 0x0010247f section, .fini: 0x00102480 - 0x00102497 section, .rodata: 0x00102498 - 0x0010263b section, .data: 0x00102640 - 0x00102adb section, .eh_frame: 0x00102adc - 0x00102adf section, .mmu_tbl: 0x00104000 - 0x00107fff section, .init_array: 0x00108000 - 0x00108003 section, .fini_array: 0x00108004 - 0x00108007 section, .bss: 0x00108008 - 0x00108037 section, .heap: 0x00108038 - 0x0010a03f section, .stack: 0x0010a040 - 0x0010d83f 100% 0MB 0.5MB/s 00:00 Setting PC to Program Start Address 0x00100000 Successfully downloaded /-----/projects/zybo/ZYBO_getting_started/ZYBO_getting_started.sdk/getting_started_with_ZYBO2/Debug/getting_started_with_ZYBO2.elf Info: ARM Cortex-A9 MPCore #0 (target 2) Running So it's "running", there is no debug config, and the Hello World demo says I should see: > The demo will be running on the ZYBO. Try playing around with the 4 switches (labeled SW0-SW3). Doing so should light its respective LED. Also over the serial port, pressing each button (labeled BTN0-BTN3) will produce the message “button x pressed”. Any suggestions appreciated. What do I do? Create a debug config for this and try again? GogMagog
  6. I have an error trying to Program FPGA or launch program(Run/Debug) by Xilinx SDK on ZedBoard (through J17 USB-JTAG) with connected Analog Discovery 2 to the same laptop. I noticed that Analog Discover 2 USB interface and ZedBoard’s USB-JTAG (J17) have the same hardware id VID/PID. So the issue can be caused by that. Using Vivado: Program and Debug->Open Hardware Manager-> Open Target I can select correct USB interface and can program FPGA. In SDK I have an error listed below. Is there are any way to recognize hardware target in SDK and configure hardware server by some additional info (Device instance path(exmpl: USB\VID_0403&PID_6014\210248782835), TID, UID(Hardware target properties in Vivado HW manager)) to be able Program FPGA or launch program? Is there any other way to handle this USB conflict. Vivado rev 2014.3.1 Errors: 1) FPGA Configuration failed.Connection to Board Failed Failed to open Cable Node jsn-Analog Discovery 2-210321A3689C on TCP:127.0.0.1:3121 2) Unexpected error while launching program. com.xilinx.sdk.targetmanager.TMException: Connection to Board Failed Failed to open Cable Node jsn-Analog Discovery 2-210321A3689C on TCP:127.0.0.1:3121 at com.xilinx.sdk.targetmanager.internal.TM.isFPGAConfigured(TM.java:372) at com.xilinx.sdk.debug.core.XilinxAppLaunchConfigurationDelegate.isFpgaConfigured(XilinxAppLaunchConfigurationDelegate.java:299) at com.xilinx.sdk.debug.core.XilinxAppLaunchConfigurationDelegate.launch(XilinxAppLaunchConfigurationDelegate.java:247) at com.xilinx.sdk.debug.ui.XilinxAppLaunchDelegateWrapper.launch(XilinxAppLaunchDelegateWrapper.java:31)
  7. Hello all tech-lovers; Do any of you guys have experience using Eigen library (http://eigen.tuxfamily.org/index.php?title=Main_Page) in bared metal OS ? When I try to define a matrix like : xil_printf(" TP CC 0 \r\n "); MatrixXd m1(6,6); MatrixXd m1_inv(6,6); xil_printf(" TP CC 1 \r\n "); the program is compiled and built, but when running it on the board, it HALT happens! I saw the assembly code of the line that exception happens, it is 0010da80: ldr r0, [r0] in which r0= 3758100524 I think the halt is because of referring to the address( decimal: 3758100524, Hex: E000102C )which is out of range of the address bus of Zybo! However this code works fine on PC ( X86) But I don’t know why my c codes convert to this assembly code. I would appreciate if any of you guys have any hint or experience on that.

    Hello; have any of you guys had any experience with axi_perf_mon IP core? can you refer me to a help or tutorial of it?
  9. Hello everyone; I am using Zybo board with standalone OS using Xilinx SDK. I wonder to know if there is any library or board support package that I can get the value of PC (Program Counter). The reason I am looking for that, is that I want to measure how much clock cycle does a portion of my code take (by calculating difference between PCs at two test points of the code). Appreciate your comments.
