The boot code does not support byte address to bus address wrapping. So the maximum image size that can be access is 64 kbytes. What this means is that if the read address is 0xFF00, the read size is 0x200 and the I2C bus address is 0x50, then 0x100 bytes will be read from 0xFF00 at bus address 0x50, followed by 0x100 bytes from 0x0000 at bus address 0x50. The bus address does not increment when the address rolls over.
