  1. We don't have any plans to support 3rd party products in WaveForms.
  2. Executables will be posted in the next few days. But if you'd like to build it on Windows you can do one of the following: Install git for windows Install cygwin If you have Win 10, you can install a Linux Subsystem within Windows Ubuntu Other distributions If you don't want to use git clone, you can download the source repository as a zip file.
  3. Have you verified that DDR is working properly? https://forums.xilinx.com/t5/Embedded-Processor-System-Design/Problems-about-XAPP1026-on-KC705/td-p/698600
  4. I would look on Analog Device's wiki. Also look for how to cross compile QT.

    Problem with CMOD A7

    We have found that a 100nF capacitor attached across VBUS and ground near the connector makes the Cmod A7 more tolerant of out of spec cables and we will consider adding it to a future revision. There aren’t any pads for the capacitor, which makes it a bit challenging to solder in a 10V, 100nF ceramic capacitor. We managed to stack it on top of half of D1 and half of C65, which are both on the bottom of the board. When testing with USB.org certified cables, we haven't been able to reproduce any connectivity issues. We also recommend plugging in the cable into a port directly on the motherboard or into a USB hub instead of a front panel USB port.

  9. All our boards (except Cmods) have JTAG pins or staggered holes to which you can connect any JTAG programmer, including the Xilinx platform cable 2, but it's not needed because all our boards have JTAG over usb which you can control through Vivado or other tools. For alternative boards, the Cmod S7 has the same form factor but a smaller FPGA. Next up is the Arty A7 with same FPGA as the Cmod A7.

  10. We don't have any reports of USB connectivity issues on the Cmod S7.
  11. There may be a problem with the network switch. Have you tried a different switch? Is the switch passing traffic for any other devices? Have you tried pinging the laptop from the Zybo? Are the IP's on the same subnet? When connected to the switch: Use tcpdump on the Zybo to see if any packets are going out or coming in. Use Wireshark (if Windows) or tcpdump (if Linux) on the laptop to see if packets are going out or coming in.
  12. Hello, and welcome to the forum. Sounds like you built an image with initramfs (which works fine), then you changed the config to rootfs and rebuilt the image. Is this correct? If so, did you clean the build after changing the config to rootfs? petalinux-build -x mrproper Petalinux leaves some build artifacts behind that are incompatible if you change from initramfs to rootfs. Doing a clean build resolves many issues in Petalinux.
  13. 2017.4 is the latest we have now. We don't have any special maintenance commitment of one board over another. There is a lot of overlap between the Petalinux projects, so upgrading the first board will take the longest, and the other ones will be quicker, but we still have to validate that all the interfaces work on the new version. The best estimate I can give right now is that we would wait for the 2019.2 release in December, and upgrade our projects in Q1 next year.
  14. Yes, we confirmed with the engineer that the 100 ohm impedance is there. It is part of the FMC spec.
  15. Not yet. It's on our roadmap, but not yet scheduled. For which board were you asking?
  16. Take a look at the following threads. They should help you get started. https://forums.xilinx.com/t5/Embedded-Linux/move-bare-metal-standalone-app-to-linux/td-p/710967 https://forums.xilinx.com/t5/Embedded-Development-Tools/Porting-bare-metal-SDK-application-to-Linux-Device-Driver/td-p/786670
  17. Yes, we have 2017.4 BSP's on our github. Make sure you get the correct one for your board. There's a z7-10 and a z7-20.
  18. Try the manual install for troubleshooting. This is what the wizard does behind the scenes.
  19. Duplicate. https://forum.digilentinc.com/topic/18742-help-trying-to-install-labview-on-raspberry-pi-3-b/
  20. BSP files can only be built with the specified version. New versions are not compatible with previous versions and require a complex upgrade process.
  21. The issue seems to be with openblas: https://bugzilla.redhat.com/show_bug.cgi?id=1516976 I suggest you ask on the openblas forum.
  22. https://www.digikey.com/product-detail/en/on-semiconductor/FDV301N/FDV301NCT-ND/458954 It's Q9 on the last page of the schematic. This is for Rev. C.
  23. What have you tried so far to fix the error?
  24. Bare metal is a stand alone program that runs on the PS without an operating system and is developed and deployed though Xilinx SDK. With Linux, you run Linux on the board and write a regular Linux application using the Linux toolchain. I suggest you read up a bit on both and see which you prefer.
