We have TWR-POS-K81, I have been trying to configure the N25Q_256 to quad mode, the enhanced volatile register does indicate that the flash has entered into quad mode ( the register reads as 0x11), I have been trying to read using different commands (0xEB/0x6B/0x0B) but the returned data always seems to be 0xCCCC only ( after the flash erase) , the SCLKCFG, I tried programming with divide with PLL (120MHZ) with 2/3/4, but there doesn't seem to be any difference.
Any hints/clues will be greatly appreciated.
regards
Krishna
