  1. Hi Bianca, I searched the web for MSVCP110.dll and found this which solved my problem regarding being unable to de-install Vivado 2015.4. After de-installing I was able to re-install, and go through the tutorials - lo and behold: flashing lights! After having had all of that fun, I will now go back to the boring tast of reading the book Many thanks and best regards, AG
  2. Hi Bianca, It's nice to see that you are still with me on this I searched for MSVCP110.dll on the good machine, and then compared the results against the "bad" machine, but could not find any significant differences. Anyway, I did a "repair" on both the installed Microsoft Visual C++ 2015 and the installed Microsoft Visual Studio 2015, to no avail. Taking your advice, I then tried to reinstall Vivado without uninstalling, but the installer refuses to install in the existing directory. I guess that means I will have to just try deleting the old directories and then try reinstalling. You agree? Best regards, Ag
  3. Hi all, I have now confirmed that my 2015.4 installation is indeed defunct. I logged into another machine and started the Vivado 2015.4 which I had already successfully setup and tested for my ARTY board, went to "Help->add design tools and devices" and added the zync7 devices to the checked boxes to install whatever is needed for the ZYBO, and after successfully adding the devices and restarting Vivado 2015.4, I performed the tutorials with no problems and with the ZYBO working as expected. I then went back to the problem installation and tried "Help-> add design tools and devices" there, and again got the error message as above (MSVCP110.dll missing). So that installation obviously was causing the problems. I may just abandon that installation and use the other machine, or I may look closer into the problem machine to find out just what went wrong. Thanks to all contributors for the help you have provided. Best regards, Ag
  4. Hi Bianca, I first tried to de-install using "Xilinx Uninstall 2015.4" in the program menue, then using Windows7 standard de-installation menue, then I tried using "xsetup.exe" in the Xilinx/downloads/Vivado_HL_WebPACK_2015.4 directory, and also in the .Xilinx directory. In each case I get this error popup message: "The program cannot be started, as MSVCP110.dll is missing on the computer. To solve the problem, install the program again." (My translation of the the German message.) How do I re-install - just delete all relavent directories and hope for the best, or is there a better solution? Regards, Ag
  5. Hi Bianca, Thanks again. Also, because the second tutorial works fine, I am confident that the ZYBO board files are properly installed (and were sourced as per CiprianĀ“s link), and I therfore too began to suspect the 2015.4 installation. Before re-installing Vivado, I would like to be clear on a few issues: 1. My 2015.1 installation is on a freshly installed Windows7 virtual machine. My 2015.4 installation is on the same host where the VM is installed, and it already had Xilinx ISE 14.7 installed. Is it OK to install Vivado 2015 on same system together with ISE 14.7? 2. When testing the project from kypropex, I do the following: start Vivado 2015.4, click "Open Project", navigate to subfolder "LED_test" found in his downloaded directory, click the LED_test Vivado Project File, then click OK. After the project loads, I "Open Block Design" and then click "Validate Design". It validates with no errors or warnings. Then, I start "Generate Bitstream" and the critical messages and errors occur. Am I doing something wrong? Why do my tutorials show no errors or warnings? 3. I notice that in the tutorial screenshot and in the project from kypropex, the processing_system7_0 displays 3 unconnected TCC0_WAVEx_OUT connections, an unconnected SDIO_0 and an unconnected USBIND which do not appear when I add the IP. I tried re-customizing the IP in alignment with Kypropex's custom IP, but I am not able to get the GPIO MIO pins set in alignment (the green/gray activation status of each pin). I also noticed that "QUAD SPI Flash" is set on his and was not set on mine. Can you exlain where these settings are originating (apparently not from the board files)? As an added note, I loaded the bitfile from kypropex's project as Ciprian suggested, and the ZYBO LEDs flash as they should. Best regards, Ag
  6. Sorry, but my screen shots seem to dissapear when I sumbit, and I am not allowed enough file upload space to provide a document containing the screen shots. Here are the errors and messages: [Constraints 18-631] No BOARD_PART_PIN found named 'btns_4bits_tri_i_0. [design_1_axi_gpio_0_0_board.xdc:3] (11 more like this) [DRC 23-20] Rule violation (NSTD-1) Unspecified I/O Standard - 12 out of 142 logical ports use I/O standard (IOSTANDARD) value 'DEFAULT', instead of a user assigned specific value. This may cause I/O contention or incompatibility with the board power or connectivity affecting performance, signal integrity or in extreme cases cause damage to the device or the components to which it is connected. To correct this violation, specify all I/O standards. This design will fail to generate a bitstream unless all logical ports have a user specified I/O standard value defined. To allow bitstream creation with unspecified I/O standard values (not recommended), use this command: set_property SEVERITY {Warning} [get_drc_checks NSTD-1].

  7. Hi kypropex, Thank you helping out on this issue. " First of I don't particularly understand where you have gotten your sources from, they seam to be a combination between several tutorials; I would recommend, choosing one tutorial and sticking to it and if it dose not work search for a new one (this is assuming I am right). " Actually, I am going through "The Zync Book" from start to finish and am using "The Zync Book Tutorials" downloaded from the link referenced in the bootk, so I am being consistent in that I am using one tutorial source. The first tutorial does not work for me, the second one does. " What is missing from the log is the programming of the .elf file (this is the compiled C project which you have written in SDK) to the board, this is a bit peculiar because the processor has been reset and configured, which usually happens when the elf is written (as far as I know). In order to program the .elf file on the Zybo board you have to right click on the project -> Run As -> Lunch on Hardware (System Debugger) (please refer to attachment 1 of this message). " The tutorial says to use Run As -> Lunch on Hardware (GDB), which I did. That explains why you did not see the .elf log entry, which is apparantly supressed with GDB. I re-ran as Lunch on Hardware (System Debugger) and thereby do see the .elf log entries. Nevertheless, the ZYBO does not respond. I closed my tutorial project in Vivado and then opened the project you provided. Upon doing a "validate Design" I get 12 critical messages and 3 errors (see screen shot below). As a novice, I am guessing that we have different ZYBO board files being loaded. Your project obviously does not work for me. I again followed the instructions in the Zync Book tutorial for downloading and installing the board files. Here is how my directories look (files added as attachment): Can you make any sense of the above? Thanks again for any help.
  8. Hi Bianca, Sorry to have to come back on this, but it seems I still have a problem. My ZYBO works with Vivado 2015.4 when I go through tutorial for "C:\Zync_Book\sources\zybo\zynq_interrupts\interrupt_counter_tut_2B.c", but when I try tutorial for "C:\Zync_Book\sources\zybo\first_zynq_design\LED_test_tut_1C.c" I again get no errors, but no response from the ZYBO. The DONE LED lights up green, the ZYBO does appear in the "View Target Connection" "JTAG Device Chain" before and after "Run as -> Launch on Hardware (GDB) (see screen shot below). I already tried again re-installing the cable drivers, but that does not help with this tutorial - no lights flashin after launch. I reconfirmed that this tutorial does work under 2015.1 (LEDs flash in the expected pattern). I first suspected a clock problem (see 2nd screen shot), but this looks the same in Vivado 2015.1, which does work. Here is the output from SDK.log: 17:50:44 INFO : Launching XSDB server: xsdb.bat C:/Xilinx/SDK/2015.4/scripts/xsdb/xsdb/xsdb-server.tcl 17:50:47 INFO : XSDB server has started successfully. 17:50:57 INFO : Processing command line option -hwspec C:/Zync_Book/first_zync_design/first_zync_design.sdk/first_zync_system_wrapper.hdf. 17:51:00 INFO : Checking for hwspec changes in the project first_zync_system_wrapper_hw_platform_0. 17:51:30 INFO : Connected to target on host '' and port '3121'. 17:51:49 INFO : Connected to target on host '' and port '3121'. 17:51:49 INFO : 'targets -set -filter {jtag_cable_name =~ "Digilent Zybo 210279772245A" && level==0} -index 1' command is executed. 17:51:50 INFO : FPGA configured successfully with bitstream "C:/Zync_Book/first_zync_design/first_zync_design.sdk/first_zync_system_wrapper_hw_platform_0/first_zync_system_wrapper.bit" 17:52:22 INFO : ps7_init is completed. 17:52:22 INFO : ps7_post_config is completed. 17:52:23 INFO : Processor reset is completed for ps7_cortexa9_0 So now again I am stuck.

  9. Hi Bianca, Thank you for your continued support. To clear, my ZYBO board works perfectly when using Vivado 2015.1 (or perhaps better stated, using Xilinx SDK 2015.1, since the problem first makes itself apparent in SDK). I only have this issue when using Vivado/SDK 2015.4. I assume the board gets programmed, since the SDK log states that "FPGA configured successfully with bitstream "C:/Zync_Book/.....", and the DONE light on the board lights up green immiatly upon the completion notification. I don't see a JTAG chain appearing in the hardware manager, and the board appears as USB serial com port COM3 in the window's device manager. As you suggested, I perfomed an update to the cable drivers. That apparantly fixed the problem, since the ZYBO is now performing as expected also in Version 2015.4, so for me the issue is not solved. Thank you for your great support! Is there someway that I can give you points?
  10. Hi Bianca, Thank you for your response. I did indeed copy the board files into the new version of Vivado (C:\Xilinx\...\data\board\board_files\, and also the subdirectory "zybo" additionally copied to ...\board\board_parts\ zync\ as instructed in "The Zync Book" tutorial). I did this the same in both versions 2015.1 and 2015.4. Following your suggestion, I just tried selecting the FPGA manually, not using the board files. Doing it that way and otherwise following the tutorial, I do not get the option to "Select Board Part Interface" to associate the leds_4bits to the axi_gpio_0 output port in the dialog when running the "Connecton Automation" link. The area under "Options" is completely blank. At that point I am stuck, since I now have no LEDs defined in the block design. Can you give me some further assistance? Many thanks.
  11. Hi curtoid, I thank you for your response, but it appears to me that my issue is unrelated. I cannot even get the simple tutorial which just blinks the 4 LEDs to work with Vivado 2015.4, and there is no code included there regarding audio initialization. Also, the link which you referenced is dating back to Vivado 2014.x whereas my ZYBO is working fine with Vivado 2015.1. I am a newbie regarding this environment and maybe I am missing something, but it seems to me that either the ZYBO board files need to be updated to match the new Vivado version, or the new Vivado version is in some way defunct, at least in regard to ZYBO. I am not sure how to address this. I feel like I am stuck between Digilent and Xilinx as to who is at fault and therefore to whom to address the problem. expecting each to respond saying the problem belongs to the other. In any case, my issue is still unsolved. In the meantime I will plug along using the 2015.1 version until I have learned how to follow the program steps in a debugger and hope to find insight as to how to correct the problem or am able at least to better localize and define the problem area more specifically.
  12. Hi, I recently purchased a ZYBO board and began testing it using the Digilent getting started tutorials using Vivado 2015.4 Webpack on Windows7. After meticulously following the tutorials serveral times, and each time with the same result - no errors but board does not respond (no blinking lights, no reponse to buttons), I began to suspect that my ZYBO was defective. As a last resort, since the tutorials are based on Vivado 2015.1 ("or later"), I created an VirtualBox Windows7 machine and installed Vivado 2015.1 Webpack on it and again went through the tutorials. Using Vivado 2015.1, everything works perfectly. So here is my question: what do I need to do to use ZYBO board with Vivado 2015.4? I do not want to work with outdated software. Any ideas? Thanks in advance for any help!
