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