  1. Good Day, I have followed the Nexys 4 DDR tutorial - getting started with microblaze servers: https://reference.digilentinc.com/learn/programmable-logic/tutorials/nexys-4-ddr-getting-started-with-microblaze-servers/start?redirect=1 I have however run into an issue. I have managed to set up the hardware, and export to the SDK. However running tera term I am met with "connection refused" or "connection timed out". I have managed to accomplish all steps with exception of 12.2 (STDIO) as it is not available in 2018.3. Would there be any suggestions or advice how to remedy this issue? Regards, Luke Abela
  2. Good Day, I am currently working on a project which entails the interfacing of a Nexys 4 DDR to a DAC8803EVM evaluation board. I am however having trouble connecting the generated clock of 50 MHz to the DAC. The DAC requires a clock of 50 MHz for optimal operation. Would it be too much to expect the IOBs of the nexys 4 ddr to output 50 MHz at the board connectors at full signal strength (i.e. minimal to no reflections), or has the board been predesigned with this situation in mind? Kind Regards, Luke
  3. Hello again, Thank you for your assistance, I have now solved my issue. If you could kindly aid with me a final matter however, if you progress further along the tutorial, the tutorial states that you should be able to find a tab known as STDIO, this is unavailable for me on Xilinx SDK 2018.3 Could you kindly provide any information as to have to remedy this? Thank you for your aid, Luke
  4. Hi JColvin, Thanks for the response, I ran through the tutorial and my issue is that block automation is not appearing when I input the Memory Interface Generator, hence why I clicked on it. Would you have any advice on this matter, alternatively is it essential to the setup of the echo server? Regards, Luke Abela
  5. Good day, I am currently attempting to set up an ethernet configuration on the Nexys 4 DDR FPGA and was doing so by following this link: https://reference.digilentinc.com/learn/programmable-logic/tutorials/nexys-4-ddr-getting-started-with-microblaze-servers/start However, my issue arose with the Memory Interface Generator IP. The version of Vivado used for this tutorial was a 2015 edition, my edition is 2018.2. Since the 2015 edition, the run block automation option for the Memory interface generator IP is no longer available, and the page displayed below loads. I viewed the Xilinx tutorial on this generator, however, I have not been able to achieve the same pinouts as are displayed in the tutorial I was following. Could someone kindly advise a course of action? Thank for your time, Regards, Luke Abela
