Where to add new block in NVM? - cent_21st - 2012-09-28 15:34:00

In our target board, we use 32K x 8 EEPROM.  Our NVM is partitioned into
non-relocatable area and relocatable area.  In the non-relocatable area,
there is block reserved for machine serial number, a block reserved for
clock value, and number of other blocks for different variables.

In the relocatable area, we have two big blocks.  One block stores machine
events and the other block stores machine diagnostics.

I need to add one byte block to our NVM.  This variable will have two
possible values, either the left operator station is active or the right
operator station is active.

Where should I add this block?  In non-relocatable area or relocatable
area?
What might be the reason for partitioning NVM into non-relocatable and
relocatable areas?


Thank you!
