I try to read some bytes in QPI mode and I read always the same byte 0xCC.
Operation is: first after power up, enter QPI Mode command, then PP (02h) page program in QPI mode and Quad I/ORead in QPI mode.
Address length is 24 bytes, clock frequency 10MHz.
Any suggestion? Maybe must be some previous initialisation commands or configuration registers writing?

To add to the above request the ReadID command in QPI mode gets the correct answer. 0x01,0x60,0x18.
So clock, and physical I/O ports are OK.
I try Quad I/ORead (0xEB) and QuadOutputRead(0x6B) commands in QPI mode even in erased sectors with bad results.
Any suggestion?
