  1. Hello, I am currently working with the Pmod MicroSD Card Slot, and am trying to interface it with the Zybo Z7 board (although I would ideally eventually interface it with the Spartan 7 SP701 Evaluation Kit). I discovered, while trying to use the PmodSD IP files in my block design, that the versions of Vivado I am using (Vivado 2021 & 2022) do not support the IP. When searching through the forums, I found other posters from a couple of years ago who encountered this issue as well. My question is: is this information still accurate (the IP is no longer supported), or have there been any new developments regarding support for this Pmod SD device? If not, would anyone happen to have any recommendations for resources to use while implementing SPI for the SD card (projects, guides, etc.)? Ultimately, I need to write values from the on-board XADC (1 MSPS) onto the SD card. I chose SD in particular because it allows for a fast stream of data (UART was too slow, and I need as high of a sampling rate as possible for a received signal). This XADC output data (stream of 12-bit values) will need to eventually be accessible by MATLAB for plotting and signal processing. I am still a beginner, so any recommendations would be greatly appreciated. Please let me know if I should provide any more information regarding my devices/constraints of the project. Thank you!
