Upgrading the BootWare program and

applications through the serial interface

Introduction to Xmodem

You need to use the Xmodem protocol when upgrading the BootWare program and

applications through the serial interface (console interface).

XModem is a file transfer protocol widely used for its simplicity and good performance.

Modem transfers files through serial interfaces. It supports transmission of packets in 128

bytes and 1024 bytes, error check (checksum and CRC), and error retransmission (generally

the maximum number of retransmission attempts is 10).

XModem transmission is completed by the cooperation of a receiver and a sender. The

receiver sends a negotiation message to the sender to negotiate an error check method.

After the negotiation, the sender starts to transmit data packets. After a complete packet is

received, the receiver checks the packet using the agreed method.

• If the check is passed, the receiver sends an acknowledgement message to the

sender. Upon receiving the message, the sender continues to send the next packet.

• If the check fails, the receiver sends a negative acknowledgement message to the

sender. Upon receiving the message, the sender retransmits the packet.
