Sharing flash sector when using dual-bank mode.

[Eitan]

Hi,

I'm using the flash in a dual-bank mode. I would like to have a common (shared) sector between the 2 banks for storing configuration data.

This becomes somewhat tricky when addresses are shifting according to the active bank. How should I go about this?

Suppose my configuration is on FLASH_SECTOR_7_BANK1

How do I access this data when the active bank is 2 ?

If banks are swapped, it's in the normal position of bank 2 sector 7.

if (SWAP_BANK == 1):
  address = 0x081E0000
else:
  address = 0x080E0000

Note that SWAP_BANK is only activated after a reset and not on-the-fly.
