  1. Please look over the following links as they may answer most of your questions: https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842132/XADC https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842572/Zynq-7000+XADC+to+PS+App+Note https://forum.digilentinc.com/topic/4636-xadc-ps-side-zybo-zynq/ https://forum.digilentinc.com/topic/3765-xadc-on-zybo-gives-inaccurate-voltages/ https://forum.digilentinc.com/topic/16611-reading-xadc-from-user-space
  2. It's possible you didn't install the SDK when you installed Vivado. Run the Vivado installer again and make sure the SDK is also checked for installation.

    pmodBLE

    Are you expecting the PmodBLE to stay connected when it has no power or are you expecting the two PmodBLE's to reconnect automatically once they are powered up?
  4. It's good to hear that it's working but I know it's frustrating when you don't know why something started working.
  5. Ok. It's a good sign that TX and RX are flashing and that the COM port is visible. Connect to the COM port with 115200 Baud using TeraTerm or some other console. Press the SRST button. Hopefully you'll see some messages on the console that should give us the next hint.
  6. 1) https://github.com/Digilent/Petalinux-Zybo-Z7-10 2) Download the BSP and decompress it. BOOT.BIN and image.ub are in pre-built/linux/images
  7. We just pulled a PYNQ from the shelf that hasn't been powered on in months also and it booted fine. We powered the board over USB. Can you try that? Do you see a new COM port in Device Manager in Windows when connecting a USB cable Are TX and RX LED's flashing at all in the first minute after powering on?
  8. We just tried booting a PYNQ and it took 45 seconds for the FPGA done LED to light up and we could see the Linux prompt on the console. Did you wait that long after turning on the board?
  9. Please confirm the following: Jumper JP4 is set to SD You flashed the latest PYNQ-Z1 image from here. How did you flash the image to the SD? Questions: How are you powering the board? USB or External power supply? Are your SD cards a high quality name brand or a no-name brand. We have come across inexpensive SD cards that can be used as storage but will not boot. They behave as if no card is inserted. We recommend SanDisk Class 10
  10. Thanks for reporting. There was a problem with the project. We updated the project and the instructions in the README. Just run the following commands: git clone https://github.com/Digilent/Petalinux-Arty-S7-50.git cd Petalinux-Arty-S7-50/Arty-S7-50/ git submodule update --init petalinux-config petalinux-build
  11. Sorry, I meant petalinux-config, not rootfs. Actually, petalinux-config is always run before petalinux-build, but I can see why you thought otherwise... the "Configure SD rootfs" heading is the same size as the previous ones and makes it look as a continuous flow. The Configure SD rootfs section is an alternate configuration from the step that are before it. I changed the heading size in the document to hopefully imply a break and added a note about running mrproper. Let me know if it's more clear now.
  12. We have boards now. If you mentioned at some point on the forum that you're having USB issues, I passed on the email you have on the forum account to customer service so they can contact you for a replacement. If you're reading this post and you haven't made any mention on the forum, send me a private message.
  13. The two petalinux manuals above are all you need. The source for the bit file is in Vivado. Then you export a .hdf file from Vivado (which contains the bit file) and you import the .hdf into Petalinux. Search for "hdf" in these two petalinux manuals.
  14. When you reflashed the firmware, did you see Success confirmation like this?
  15. Is this a bare metal application only with no Linux involved? If yes, I will move the thread to the FPGA section. thanks
  16. If you run the rootfs config first without running a build before the rootfs config, it should build fine. mrproper is mentioned in the following Petalinux docs from Xilinx: https://www.xilinx.com/support/documentation/sw_manuals/xilinx2019_1/ug1144-petalinux-tools-reference-guide.pdf https://www.xilinx.com/support/documentation/sw_manuals/xilinx2019_1/ug1157-petalinux-tools-command-line-guide.pdf
  17. We have it in our pipeline to update all the Petalinux projects in the next few months. The upgrade operation is complex and we don't recommend customers try it on their own.
  18. We've used it without issues. Did you configure the kernel and the device tree as described here?
  19. For data communications, look for a USB to DB-25 Parallel cable. (eg. link1, link2, link3) There is somewhat of a chance that Adept would recognize such a cable and you would be able to also program the FPGA through it, but we can't guarantee that. If Adept doesn't recognize that cable, you'll need to get one of our JTAG programming cables: JTAG-USB, JTAG-HS2 or JTAG-HS3 Here is a table indicating which software supports which cable.
  20. Did you press the PROG button to flush out the data to the SD card before removing it as described here?
  21. FYI, Attila is on vacation returning on Oct. 9th.
