  1. Hello, while waiting for my hardware to arrive I play with WaveForms a bit and found some things that don't work out as they should. I use the 64bit WaveForms 3.16.17 rpm from the beta page on Fedora 27. For my tests I always started it with vanilla settings by deleting static.dwf3 1. On startup the application tells me that no device could be found and presents the "Device Manager" window, in which I select a demo device. When I select DDiscovery, sometimes (not always) a half transparent window "Opening device" stays open. This seems to not happen when I select a different device. 2. I can't select fonts in the options dialog. The application starts with Cantarell and Monospace. Regardless what I do Cantarell stays the same and the script font changes to DejaVu Sans Mono. 3. When I choose the "Dark" style in the options the digital color option also changes from default to dark. When I switch back to another style like "Fusion", the digital color stays dark. This can easily be changed manually, but 2 options changing at the same time confuses at first. Have a nice day Stefan
  2. Hello, We are trying to add the Cora Z7 as a custom board into Matlab to allow model based development. We have been following this guide: define-and-register-custom-board-and-reference-design-for-zynq-workflow, but are getting stuck at linking to the Linux bit (the last step); (step 4 of section 'Integrate the IP core with the Xilinx Vivado environment' referenced here Getting Started with Targeting Xilinx Zynq Platform). We have Petalinux installed on an SD card, and can ssh into this etc., but its missing the necessary matlab customisation. We need to either use build root, or customise the Petalinux build. From Mathworks: So my questions are: Does anyone have a built image for the Cora Z7 using either of these methods? / a Linux image that we can use for this board with Matlab?. Can we use buildroot with the Cora Z7, such as by using the Zybo as an example and adapting this to suit the Cora? HAs anyone tried this? Does anyone have experience of the drivers necessary for Matlab, and how to add these to and rebuild the Petalinux kernel source? Cheers, Sean.
  3. I am evaluating the possibility of using the AD-2 for my student labs (in place of scope/signal gen/PS, etc) I want to try waveforms in demo mode on my Ubuntu laptop. I get the following error when I try to install Waveforms after Adept: The following packages have unmet dependencies: digilent.waveforms: Depends: digilent.adept.runtime (>= 2.26.1) but 2.21.3 is to be installed I installed Adept, but apparently it wants a later version than I am getting. OS: Ubuntua 21.04, arch is 64 bit intel. Update: I installed 3.16 (previous version), and that worked. Apparently 3.17 is very new. But how do I get into DEMO mode? Update: saying ok when no device is detected gets it into demo mode. I left this in because maybe someone else will have the same problem.
  4. Hello, I'm doing my first steps with Waveforms and a Digital Discovery and found a curious situation where single data lines where out of sync depending on zoom. Have a look at the screenshots to see that I configured a 10 second record of various data. The record has been stopped manually. If you look at the first screenshot the Serial Out and its related Data line are askew. When I zoom in a bit via mousewheel they are in sync. This effect does not occur after I saved and reloaded the data.
  5. The actual beta version of Waveforms is 3.16.35, but the last one featuring a Linux rpm is 3.16.17. Overall these betas are released as a wild mixture sometimes with only the Windows version. Why is that so? I would like to testdrive, but need rpm. Thanks
  6. Hi, We are trying to use the ADP in remote locations where we would like to remotely connect. We can add an in between computer with a vpn connection to get remote access. It would be much slicker to be able to stream data to our server running waveforms via a vpn from this device in the field? Do you have any info/references on the linux implementation in the ADP? Are we able too SSH over ethernet? Reference material seems to be lacking here?
  7. Hello Everyone, I want to gain Linux certification and I have search about it for a long time and I have shortlisted a few certifications but I am confused about which one is better for me. I have 1 year experience in PHP and want to become linux certified. Can anyone suggest me which is better for me? 1. LFCS (Linux Foundation Certified System Administrator) 2. Linux+ CompTIA 3. GCUX – GIAC Certified Unix Security Administrator 4. LPIC 3 – 300 – Linux Enterprise Professional Certification 5. LFCE (Linux Foundation Certified Engineer)
  8. Hi all! I'm running Ubuntu 20.04.1 LTS on ryzen 1700 with B350 chipset. When running waveforms (3.14.3, adept 2.20.2) after selecting device in Device Manager the application hangs for a while and show error box The LED on AD2 doesn't start blinking. However if I use "Force programming" from context menu (whatever it does) the error message is the same, but LED starts blinking. My Analog Discovery 2 is working perfectly fine on the same PC under Windows and on other computers under Windows (I don't heave another Linux machine available). It also was working some time ago, probably before updating from Ubuntu 19 or something like that (I'm not sure now - it was a few months ago). I did try different USB cables, different ports (different USB controllers too) and using external power supply for AD2, though I really don't think it's hardware issue as it works on the same machine on Windows. There are no errors in dmesg: [ 4535.196219] usb 1-2: USB disconnect, device number 27 [ 4537.393789] usb 1-2: new high-speed USB device number 28 using xhci_hcd [ 4537.564412] usb 1-2: New USB device found, idVendor=0403, idProduct=6014, bcdDevice= 9.00 [ 4537.564417] usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 4537.564420] usb 1-2: Product: Digilent USB Device [ 4537.564422] usb 1-2: Manufacturer: Digilent [ 4537.564424] usb 1-2: SerialNumber: 210321AD5BE1 [ 4537.576482] ftdi_sio 1-2:1.0: FTDI USB Serial Device converter detected [ 4537.576527] usb 1-2: Detected FT232H [ 4537.587553] usb 1-2: FTDI USB Serial Device converter now attached to ttyUSB0 [ 4537.604594] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0 [ 4537.604617] ftdi_sio 1-2:1.0: device disconnected Disconnect, I suspect, is because of dftdrvdtch which probably reconfigures the FTDI device thus disabling virtual serial port. Any ideas what might be the problem here?
  9. Hello! I'm working on tutorial how to port and use PYNQ with Eclypse-Z7 and now I'm stuck on ZMOD integration. I have created device-tree-overlay based on PL.dtsi generated by petalinux with PYNQ-PRIO, applied some changes by hand and I don't know why I'm getting this error. Everything is here: https://www.hackster.io/bartosz-rycko/eclypse-z7-pynq-porting-guide-3dd24c If you could help me on this I would be grateful. Thanks :)
  10. Waveforms stopped working for me recently on one of my Linux machines (it still works on other machines with same Analog Discovery unit, same distro & kernel). On the one machine, I now always get an error dialog: Device opening failed. The device is being used by another application. Device programming failed. I've checked, and AFAICT, it is not being used by another application. The ftdi_sio driver has disconnected as it should, and no other application aside from waveforms has that usb device open. Any ideas on what might be causing this error? The only thing that changed since it used to work is that I replaced the motherboard — switching from Intel to AMD CPU.
  11. I would like to integrate PMOD NIC100 with Microzed board with Zynq 7020 running on linux. I have a SPI interface routed through the PL logic. Are there any IP that can be directly imported to Vivado for this ? OR Are there any drivers that can be installed on the linux ? Please suggest.

  13. I have been trying to install Waveforms on my new Mint20 Linux installation and have downloaded it numerous times with Firefox. After download and upon trying to instal I always get the error in the screenshot
  14. I'm fairly new to Linux and Waveforms, so apologies if I am missing something obvious. I am trying to install Waveforms on a Chromebook with Linux support enabled. The version of Waveforms I am attempting to install: digilent.waveforms_3.12.2_amd64.deb The version of my OS: $ cat /etc/*-release PRETTY_NAME="Debian GNU/Linux 10 (buster)" NAME="Debian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=debian The error I get when trying to install: The following packages have unmet dependencies: digilent.waveforms: Depends: libc6 (>= 2.14) but it is not installable Depends: digilent.adept.runtime (>= 2.17.1) but it is not installable So, it seems like dependency issues. I checked my version of libc6 and it is greater that 2.14. $ apt list libc6 Listing... Done libc6/stable,now 2.28-10 arm64 [installed] I have separately downloaded Adept 2 runtime version digilent.adept.runtime_2.20.1-amd64.deb. I get the following error when trying to install it. The following packages have unmet dependencies: digilent.adept.runtime: Depends: libc6 (>= 2.5) but it is not installable So, this seems like I need libc6 2.5 or greater, but I can't seems to find any higher version. So, I feel like I'm in a recursive loop. Any help is appreciated. Thanks!
  15. I burn a Linux image using Yocto, meta-xilinx and openembedded put after put all the required files on SD card and put it on my FPGA (ZYNQ-ZYBO-Z7020) and try to connect with it using serial communication (putty or realterm) the output is wrong I am using 115200 baudrate and this is the baudrate that recommended in the data sheet
  16. Hi, I'm using a RPi4 with Analog Discovery 2 and I'd need to use AD2 at 64bit so I'm wondering why you are not sharing sources to build libraries for a specific system with proper optimization. Best, pz
  17. Just received a new Genesys 2 board. Flashed it and trying to boot the prebuilt version of linux from arian-sdk Programmed the board according to here: https://reference.digilentinc.com/learn/programmable-logic/tutorials/genesys-2-programming-guide/start The board powers up fine, copies bbl & linux image from sdcard and then no tty output. Nothing at all. I built the sdcard using the prebuilt bbl.bin images from: https://github.com/pulp-platform/ariane-sdk/releases (I tried bbl.bin files from both 4.2 release and OpenPiton + 4.2, same result for both.) Following instructions for creating sdcard here: https://github.com/pulp-platform/ariane-sdk Board sees the sdcard, copies the sectors, and then nothing! I've tried to set breakpoints at numerous places in the linux boot sequence but non of the are ever hit. Breaking in from gdb shows $pc at 0x10040 which seems wrong for linux running at 0x80000000. Main questions are: Are the prebuilt bbl.bin images known to work? Are instructions up to date? Any suggestions on how to move forward? Thank you! Uart output is below. I expected to see some linux boot lines following the 'done!' message below but I get nothing.

  18. Hello Everyone, I just want to know Is linux interview tough? My interview has been scheduled in next week. Can anyone provide me list of interview questions for linux profile as a fresher level. I have covered some most important topics like Linux, BASH and DOS, symbolic links, daemons and some more.
  19. Analogue Discovery 2 https://forum.digilentinc.com/applications/core/interface/file/attachment.php?id=12669 https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019Ls1SAE&l=en-US Hi Firstly I would like to say what great product the Analogue Discovery 2 is, I have used it for 8 months to develop a product. It is by far the best PC scope that , I have used. Far better than a PICOSCOPE from the UK company PICOSCOPE or any of the Chinese PC scope knock offs. Analogue Discovery 2 is a serious peice of professional kit and not a toy. This a summary of all of the useful information I found when working with the Analogue Discovery 2 for 8 months 1. Always use the latest WaveformsSDK https://forum.digilentinc.com/topic/8908-waveforms-beta-download/ 2. vb.net driver rapper https://forum.digilentinc.com/applications/core/interface/file/attachment.php?id=9726 https://forum.digilentinc.com/topic/17736-digilent-analog-discovery-2-dll-driver-for-vbnet-and-c-in-visual-studio-2017/#comment-45135 3. C# complete .net rapper than can be used for vb.net as well as C# https://github.com/Andrei-Errapart/WaveFormsSDK It is possible to take full control of the Analogue discovery 2 using C# or vb.net or python or labview. 4. C# oscilloscope GUI panel that works and can be used in both VB.net and C# https://www.codeproject.com/Articles/16350/High-Speed-Feature-Rich-and-Easy-To-Use-Graphs-and I have tested this C# plugin and it works really well . 5. KICAD PCB tool projects that are very intersting This way you can make your own projects which plug onto the analog discovery 2 https://github.com/jubeormk1/AnalogDiscovery_x20_powerMainsProbe https://github.com/jamescarruthers/analogdiscovery2io https://github.com/james-everitt/AnalogDiscovery2Eurorack https://reference.digilentinc.com/_media/reference/instrumentation/analog_discovery_impedance_analyzer_sch.pdf 6.

  20. Hello to everybody! I'm built custom Embedded Linux distro which based on Digilent Base-Linux FPGA design (https://github.com/Digilent/Zybo-Z7-20-base-linux) with help Xilinx Petalinux env. In this design was implemented XADC support. From the default BSP package from Digilent repository, I added support XADC to the device tree. How I can test this implementation from a working Linux image. I need to write a driver or I already can work with XADC?
  21. Hi all, Currently I am working on a project with the aim to encrypt the communication between a drone and the ground station by using an PYNQ-Z1 board. I am facing the issue of how to convert the standalone application (bare metal) to a Linux base application in Vivado 2019.1 SDK, in order to make use of the crypto++ libray which requires the presence of an perating system to work. Does anyone know what to do to slove the issue? Thanks George
  22. Hi, I am relatively new to working with the Zedboard. I've managed to get an I2C/I2S audio example working (using bare-metal) , that i've downloaded from here. http://www.zynqbook.com/download-tuts.html Now, I would like to get the same example working using the Linux Kernel. However, I can't seem to be able to access the I2C bus. The bus appears to be there, but denies access. zynq> i2cdetect -l i2c-0 i2c Cadence I2C at e0004000 I2C adapter zynq> i2cdetect -y 0 Error: Can't use SMBus Quick Write command on this bus From looking at the SDK, the I2C appears to be at 0xe0004000 Has any one got any suggestions, or point me in the right direction to find the correct settings..? Everywhere I have googled seem to provide i2c solutions for different boards, or bespoke platform setups. What I don't understand is why it just doesn't work "out-of-the-box" with the default settings. Or perhaps, i have missed something. I am using Xilinx SDK 2018.3, and the Xilinx kernel My kernel settings are these: CONFIG_REGMAP_I2C=y CONFIG_I2C=y CONFIG_I2C_BOARDINFO=y CONFIG_I2C_COMPAT=y CONFIG_I2C_CHARDEV=y CONFIG_I2C_MUX=y CONFIG_I2C_MUX_PCA954x=y CONFIG_I2C_HELPER_AUTO=y CONFIG_I2C_ALGOBIT=y CONFIG_I2C_CADENCE=y CONFIG_VIDEO_IR_I2C=y CONFIG_SND_SOC_I2C_AND_SPI=y CONFIG_RTC_I2C_AND_SPI=y My device tree looks like this: [email protected] { compatible = "cdns,i2c-r1p10"; clocks = <0x1 0x26>; interrupt-parent = <0x4>; /*interrupts = <0x0 0x25 0x4>;*/ interrupts = <0x0 0x19 0x4>; reg = <0xe0004000 0x1000>; i2c-clk = <0x61a80>; #address-cells = <0x1>; #size-cells = <0x0>; }; The default device tree entry for i2c was disabled, so i've tried different combinations. Any help would be gratefully received Dave
  23. Hello everyone! I'm trying to install Petalinux on a Cora Z7-10 I followed all the steps described here: github.com/Digilent/Petalinux-Cora-Z7-10 but when I try to boot it I get this message: hwclock: can't open '/dev/misc/rtc': no such file or directory after this, I can't write anything in Minicom. As in my folder /dev didn't have the misc folder, following some advice that I found on the net I created the folder and first tried to soft-link /dev/rtc0 and then hard-link it also but none of those worked, I still get the same error. Did anyone go through the same issue or has any idea to solve it? Thanks you very much in advance.
