  1. @jpeyron Fixed it by trying a SD card writer on a different computer.
  2. I'm trying to boot a Zedboard using a SD card, and it fails. The Power good LED is on, but the 'Done' light remains off. I tried 4 different SD cards (all UHS-I), but later read that UHS-I cards aren't supported, so I'm using a non-UHS card and it still fails to boot. MIO6:2 headers are '01100', which is the SD card boot configuration. I've also shorted JP6 on the board. VADJ is at 1.8V The board boots successfully from QSPI - the blue LED and 4 red LEDs come on. I formatted the SD cards using both: the official SD Card Formatter & Windows 10's inbuilt 'Format' Then I copied the 5 files from the Out-of-box Demo on Digilent's website: https://reference.digilentinc.com/reference/programmable-logic/zedboard/start?redirect=1 I've also tried the 'zedboard_oob_design' from the Avnet forums, and the Analog Devices images from their website - and the board still fails to boot. I've tried the SD cards on another Zedboard, and it fails to boot on that one as well. The UART doesn't print anything (115200, 8N1) either. Is there anything I'm forgetting to check? Does the SD card require a specific format, sector size, partitions etc?
  3. Hi @attila Wavegen 2 LG was -18 (!) on my device. Loading factory settings seems to have resolved the issue. Thanks!
  4. I encountered a peculiar issue when using AWG2 of the Analog Discovery 2. Physical connections were as follows: 1+ to W2 1- to GND When AWG2 is set to generate a sine wave voltage <= 1.00V, the output seems to be a clipped version of a voltage referenced to +5V (USB +ve rail). At any voltage above that (>1.001), the output is fine. I'm using Waveforms 3.8.2 on a 64bit Win10 PC. I've attached a screen capture:
  5. @Kristoff As suggested, I used a non-zero sample rate when importing the CSV, and it decodes correctly now. A bug was filed, and subsequently patched: https://sigrok.org/bugzilla/show_bug.cgi?id=1118
  6. Using PulseView 0.5.0-git-b732b48 (which I downloaded from the sigrok page at: https://sigrok.org/wiki/Windows#Windows_installers - I used the 'pulseview-NIGHTLY-32bit-static-release-installer.exe'). Reinstalled it to make sure. I imported "WaveformsLiveData - Formatted.csv" using the default settings (as you did). Then I added the SPI decoder (using the icon > drop down list in the toolbar). I set the decoder options as you did (except with the chip select set to '-', though the result is the same with it set to Ch0 ). It decodes the first packet, but nothing after that:
  7. @KristoffI imported it as you said, but I'm having trouble getting the decoder to work: The decoder bar remains blank PS: Sorry if it's a simple question. It's the first time I'm using Sigrok, so I'm not sure whether I'm using Sigrok wrong, or importing the file wrong. I tried using a few .sr dumps I found, and the protocol decoder worked fine then.
  8. How exactly did you export the data? I've tried a CSV: I manage to import it into sigrok, but can't get the decoder to work (I'm probably importing it the wrong way: wrong sample rate etc.)
