=== System Update Control ===
The 0x4000 bytes at offset 0xFC000 are used by [[NS_Services|NS]] and [[Boot|boot]] for keeping track of the status of a system update. This area is used by the [[NS_Services#ISystemUpdateControl|ISystemUpdateControl]] commands [[NS_Services#ApplyDownloadedUpdate|ApplyDownloadedUpdate]], [[NS_Services#ApplyCardUpdate|ApplyCardUpdate]] and [[NS_Services#ApplyReceivedUpdate|ApplyReceivedUpdate]].

Starting at offset 0x180000 is an array of 0x200-byte entries, for a total of 32 keyblobs. Each one is unique compared to the others and they are all console unique. This is officially known as the "EKS" (encryption key source) area.

Encrypted partitions use AES-XTS using the same non-standard tweak (tweak[0] = sectorIdx[MSB] .. tweak[15] = sectorIdx[LSB], if using 32bit sectorIdx that means tweak[0]..tweak[11] are 0, with tweak[12]..tweak[15] containing big-endian sectorIdx) as other Nintendo AES-XTS code, initial_sector = 0, and sector size 0x4000. All encrypted partitions use console unique keydata.
