Abstract: A method is for updating an original firmware file of an I/O module which communicates with multiple host-end devices and stores the original firmware file. The method includes: receiving a current-received data packet from one host-end device; when it is determined that the current-received data packet is a first data packet constituting an update file, and that the original firmware file is not undergoing an update process, setting a status flag to indicate that the original firmware file is undergoing an update process, storing the current-received data packet; and repeating the previous steps when it is determined that the current-received data packet is not a last one data packet constituting the update file.

Abstract: A rack system includes a first ROM, a first RAM, a first control unit configured to access the first ROM, a second ROM, a second RAM, and a second control unit electrically connected to the first control unit via a communication channel and configured to access the second ROM. The first control unit is operable, in response to receipt of a request signal from the second control unit for accessing data from the first ROM, to read the data from the first ROM and to transmit the data to the second control unit via the communication channel. The second control unit is operable, upon receipt of the data from the first control unit, to store the data in the second RAM and to access the data from the second RAM.

Abstract: A method for data communication within an I2C system is provided. The method includes the steps of: a) generating a communication error code indicative of error status when data transmission from a master module to a slave module via an I2C bus fails; b) determining whether to retransmit the data to the slave module according to the communication error code; c) when the determination made in step c) is affirmative, determining whether a number of times of data retransmission(s) associated with the data reaches a predetermined number; d) when the determination made in step c) is affirmative, resetting the master module; and e) recording a communication error event according to the communication error code after step a).
