[ECOS] using fconfig

Looks like strange :

is it normal that when doing a fconfig -i, the call of the flash_erase is
executed
at the same address that the FIS directory,
that is to say, if you take in account that :

Name                  FLASH addr    Mem addr           Length         Entry
point
RedBoot             0x01000000     0x01000000    0x00020000  0x00000000
RedBoot config   0x0107EC00   0x0107EC00    0x00001000  0x00000000
FIS directory      0x0107F800    0x0107F800     0x00000400  0x00000000

Boot script timeout (1000ms resolution): 0
Update RedBoot non-volatile configuration - continue (y/n)? y
 ... Erase from 0x0107ec00-0x0107fbff: ...
My Debug string : flash_erase with block: 107f800 / block_size :400
$T0a0f:00000801;0d:f8050

does someone knows ?
