Updating Software Through a Serial Connection
Introduction to XMODEM
To update BootWare and applications through a serial connection, use the XMODEM protocol.
XMODEM is a file transfer protocol that is widely applied due to its simplicity and good performance.
XMODEM transfers files through serial ports. It supports two types of data packets (128 bytes and 1 KB),
two check methods (general checksum and CRC), and error packet retransmission mechanism
(generally the maximum number of transmission attempts is ten).
The XMODEM transmission procedure is completed by the cooperation of a receiving program and a
sending program. The receiving program sends a negotiation packet to negotiate the packet check
