Hi,
The reason both radio module parameters and the MAC address are stored first, is because of re-writing the EEPROM's FAT. By doing this, the content is actually "erased".
Re-writing the FAT is required as by default the original FAT isn't compatible with the current patche's size. We needed to increase each from 4KB to 8KB (FW and Driver patches dections).
Hope this clarifies.
Regards,
Tomer
