  1. Thank you very much. Your post was very helpful and I was able to get things working with the demo software and my trainer board. -Sean
  2. Hello, I recently purchased a Nexys A7 100T FGPA trainer board and want to experiment with Digilent's GPIO demo on Github. I downloaded the repo and extracted it with 7-zip but don't seem to see the "Nexys-A7-100T-GPIO.xpr" file anywhere to launch with Vivado. I am following the Demo Setup instructions on the Github page. I attached the the zip file that I downloaded from github. I appreciate any suggestions. Thank you. -Sean Nexys-A7-100T-GPIO-master.zip
  3. Thank you Dan. Your answer helps clarify things greatly for me on this subject. I appreciate you taking the time to help me out. -Sean
  4. Hello, In section 3 of the user manual for my Nexys A7 FPGA development board there is the following statement regarding the 2 external memories... "1Gib (128MiB) DDR2 SDRAM and a 128Mib (16MiB) non-volatile serial Flash device" I don't completely understand the specs in parenthesis? I think they may refer to configurations within the memory ICs themselves. For instance... for the DDR2 SDRAM, PN: MT47H64M16HR-25E I looked at the data sheet and saw the following configuration option listed... 128 Meg x 8 (16 Meg x 8 x 8 banks) So I just wanted to try and better understand these specs for the on board memory. thank you -Sean
