In version 2.9.0, I modified the JEDEC ID.
The system is supposed to send a "Deep power- down enter(0xB9)" command after reading the JEDEC ID.
However, after the system reads the JEDEC ID, there is no response at all.
I have already modified the values in the device tree.
Is there anything else I need to do? By the way, it worked normally in version 2.6.1.
