V3 is backwards compatible to V2 and therefore, the V2 image still exists at the beginning. Only the API version changed from 2 to 3. V3 is a block-based memory layout organized as singled-linked list with different types of blocks. This is a more flexible approach and allows us to extend it by more block types in the future. The V3 data starts with a 8-byte large header which defines the block count (u8), V3 subversion (u8) and data payload length (u16). Additionally the header contains a CRC8 checksum a 3 reserved bytes. Each block starts with a 4-byte large header which defined the block type (u8), the absolute address of the next block (u16) and a CRC8 checksum. The content itself is defined via the block type and we currently have 2 different types: 1) MAC: Contains the Ethernet interface number (u8), MAC address (6 x u8) and a CRC8 checksum. --- 9fa98591d7082087afe95583ef11e62351c98d87
