Reading JEDEC ID from user space. Is there a way to read JEDEC ID for a given NAND/NOR flash device from user space? The dataflow in this bus protocol is controlled with four multi-plexed I/O signals, a chip enable (CE#), and serial clock (SCK). Custom Feeder. The Read JEDEC ID (9Fh) command is supposed to be around since 2003. The Read SFDP command is relatively new and is documented in the JEDEC standard JESD216, published on 2011.
