I’m not entirely sure where to put this RMA, but I think the ZYBO board I just received may have a faulty LED (LD3) and a faulty microSD card from the accessories kit.
One thing at a time… first, the LED. I have been having trouble getting u-boot (and subsequently the Digilent Linux distro) to work on the board. In order to make sure that at least the PL portion was being programmed correctly, I made a basic project in Vivado 2014.1 for the xc7z010clg400-1 SoC target. The LEDs are hooked to a constant IP block [3:0] with a constant value “1111”:
But the ZYBO response does not have all the LEDs lit as expected:
I'll happily post the synthesis report, although there doesn’t appear to be a ‘smoking gun’ in there.
Back to the SD card; using the same format (FAT32) and files on three different cards (SanDisk, ADATA, and the unbranded one from the accessory kit), only the first two worked.... and they have lower speed grades than the broken one (4 and 6 vs. 10, respectively). Not sure what other evidence I can provide...
