Abstract
A system and method of updating codes stored in a controller based on the two-channel protocol standard are described. The updating system includes an application program unit, a kernel buffer, and a general purpose input/output control module. The application program unit receives the updating command and the code file via the network. The kernel buffer downloads the code file based on the updating command from the application program unit and stores the code file into the kernel buffer. The two-channel control module reads the code file stored in the kernel buffer and converts the code file into a clock signal and a data signal. The general purpose input/output control module has a clock channel and a data channel for receiving the clock signal and the data signal and transmitting the clock signal and the data signal via the clock channel and the data channel, respectively, to the controller of the network storage apparatus for updating the original codes in the controller.
