: To bootloader.
The loader sends between 1 and 512 words at a time to the bootloader to program into the NBB
flash. The Offset is the byte offset into the NBB flash of the first data word of this packet. The
GES only supports writing words at a time so this offset should always be even.

The bootloader immediately responds with this message when the bootloader receives a

UDP message to indicate to the loader that
another data packet may be sent.
