Direction: To bootloader.
This packet is sent by loader to let bootloader know that all data words have been programmed.
This causes the bootloader to perform a CRC32 of the GES application in the NBB flash. If it
verifies the bootloader will send a Finished Programming Acknowledge UDP message and then
launches the GES application from the NBB flash. If the image fails CRC32, the bootloader
sends a Bad CRC UDP message.

Opcode (112)

Direction: From bootloader.
The bootloader indicates that the CRC32 has failed verification after receiving a Finished
Programming UDP message from the loader. The GES application will not be launched from
NBB flash. The bootloader will sit there waiting for another application load to be performed.
