Hi everybody,


Can you help me with new drivers for bigger serial flash than 2M (M25P20)?


I read datasheets on

and they seem like same.

What is necessary to change ?


I found in adi_m25p20.c (driver)

PAGE_LENGHT  64 // (in 32-bit words)

it means 64*32=2048

Is it enough to change to 128 for M25P40?
