Hi David,

     Sorry, I have a doubt about the range outside, from the binary map, we
can find the Spare 3 Region size is 0x00FFFFFF - 0xFF0000 + 1 = 0x10000,
and the binary size map to this range is also 0x10000, they are equal, why
outside was happened? and can you tell me how to update the binary region's
range defined in the flash description?

Start (hex)    End (hex)    Length (hex)    Area Name
-----------    ---------    ------------    ---------
...
...
....
00FF0000       00FFFFFF     00010000        Spare 3 Region
01000000       01FFFFFF     01000000        BIOS Region


 In addition, from flash log file(please see attachment
"Lewisburg_W25Q256.log"), it shows:
Found Programmer flash chip "Opaque flash chip" (32768 kB,
Programmer-specific) mapped at physical address 0x0000000000000000.
 but, my flash chip is "Winbond flash chip", what do you think about this?
Thank you very much!
