I can read out these

0xff000000: FFFF
0xff000002: FFFF
0xff000004: FFFF
 
from my flash. 

But I still cant write any data into, I think the problem is from here
in the .tcl:

# = 555 shifted by  2 bit because lower 2 address lines are not
connected (Word Access Mode)
set FLASH_COMMAND_ADDR_555 [expr $FLASH_BASEADDR + 0x01554]
# = 2AA shifted by  2 bit because lower 2 address lines are not
connected (Word Access Mode)
set FLASH_COMMAND_ADDR_2AA [expr $FLASH_BASEADDR + 0x0aa8]

I think, it shouldnt be 0x01554 and 0x0aa8 in my x16 mode case, where
can I find these number??
