Upgrading BootWare and Application Through a Serial Interface
Introduction to Xmodem
Use Xmodem when upgrading BootWare or application through a serial interface.
Xmodem is a file transfer protocol that is widely used due to its simplicity and high performance.
Xmodem transfers files through a serial interface. It supports two types of data packets (128 bytes and
1 KB), two check methods (checksum and CRC), and error packet retransmission mechanism
(generally the maximum number of retransmission attempts is 10).
The Xmodem transmission procedure is completed by the cooperation of a receiving program and a
sending program. The receiving program sends a negotiation character to negotiate a packet check
method. After the negotiation, the sending program starts to transmit data packets. When receiving a
complete packet, the receiving program checks the packet using the agreed method.
