  1. I am trying to make RAM work on my zybo; however, it keeps failing the memory test, I have tried https://forums.xilinx.com/t5/Processor-System-Design-and-AXI/ZynQ-DRAM-fails-in-test/td-p/834342/ https://forum.digilentinc.com/topic/15755-ddr-issues-on-zybo-z7-20/ additionally, I have tried setting up different "memory part" in the settings in vivado according to these reference manuals https://reference.digilentinc.com/reference/programmable-logic/zybo-z7/reference-manual/ https://reference.digilentinc.com/_media/zybo:zybo_rm.pdf Do you know what I might be doing wrong?
  2. Any & all help is appreciated with this thread. I am 100% new rookie to FPGA. I purchased the Digilent Zybo Z7: Zynq-7000 ARM/FPGA SoC Development Board (Zybo Z7-20 with SDSoC Voucher) My intentions are to crypto currency mine a new FPGA algo called Odocrypt created by the blockchain group Digibyte DGB. Here are a couple links to the info. https://www.dgbwiki.com/index.php?title=FPGA_mining https://www.coinfoundry.org/pool/dgb5 DigiByteCoin Github Odocrypt Mining Software https://github.com/DigiByte-Core/odo-miner It will change every 10 days.

  3. Hello, I am having trouble outputting sound on Linux using SSM2603. The SSM2603 device driver loads normally. It is also registered in ALSA sound card list. However, "input / output error" is raised in "alsactl init". ("amixer" is also the same.) It plays when I play wave file with "aplay" but it does not output to "R/LOUT pin" of SSM2603. Regards, Namio
  4. I am trying to boot Linux with Linaro file system on Zybo Z7-10 without Petalinux. I would like to connect a monitor to HDMI TX output to be able to see Linaro graphical interface but I am getting errors while Linaro Ubuntu is booting, and nothing is being shown on the monitor. I am sure that HDMI output works on my board since I got HDMI demo project to work. I am using Zybo base system design from here, adapted to Zybo Z7 on Vivado 2018.2. I have generated device tree from this design using Xilinx SDK following this tutorial. I am using Digilent's u-boot and Linux kernel and I
  5. Hello everyone, I've bought a Zybo Z7 with a XC7Z010. I've downloaded the HDMI demo (link here) and I got it working - I connected my laptop to the RX port and a monitor to the TX port. Now what I'm trying to do is to have the TX connected to a monitor, build an image using Petalinux and once I program the SoC I can see the Linux booting on the monitor. I've built an image using the bit and hdf files provided on the HDMI demo project and on Petalinux kernel config I've enabled the following: Device Drivers -> Graphics support -> Enable HDMI HDCP support in MSM DRM driver

    Z7 board upgrade PMU?

    Hi everyone. I am curios if there is a relatively simple modification I can do to increase available FPGA power, especially the 1V into the FPGA, on a Z7-20 board? Background, my problem is simple. I load a design into the Zynq that is expected to drain much more on the 1V supply then what the PMU inside the board can deliver, when loaded the LD13 led goes down almost instantly indicating that the supply rails can't keep up. This is easy to do, just try to use half of the Fabric at a decent frequency (200+MHz) and you will have run out of power. So I assume the PMU was dime
