As a parameter the WLC requires the driver to access the flash device. The driver has to implement Flash_Access interface.
The WLC Versioning and Compatibility

The WLC accept data formats from older version. Latest version of the WLC will update data format from older versions to the current one.
Current implementation of WLC has version 2. The data format from current version incompatible with data format from previous versions, and could not be
used with previous versions.

Internal Memory Organization
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The WLC divide the memory that are define by start_addr and full_mem_size to three regions:
- Configuration
- Data
- States
- Configuration
The Configuration region used to store configuration information. The user can use it to recover the WLC from memory dump.
The Data - is a region where user data stored.
