Why can't Cypress NAND flash be recognized by Cyclone® V SoC FPGAs?

Environment

  • Intel® Quartus® Prime Standard Edition
    • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Cypress NAND flash might not be recognized by Cyclone® V SoC FPGAs if you have followed the Cyclone® V GX, GT, E, SX, ST and SE Device Family Pin Connection Guidelines, which recommends connecting NAND_RB through a 1KΩ -10KΩ pull-up resistor to VCCPD_HPS.

    Resolution

    For Cypress NAND flash, it is recommended to connect NAND_RB through a 10KΩ -50KΩ pull-up resistor to VCCPD_HPS. 

    The Cyclone® V GX, GT, E, SX, ST and SE Device Family Pin Connection Guidelines will be updated with this information in a future release.
