Abstract
A method to improve the updating of firmware in a firmware updating system, uses serially-sent data packets containing the update and data. The firmware updating system includes storage, including an expander/switch, a baseboard manager controller (BMC), and a storage interface. A universal asynchronous receiver/transmitter (UART) for serial communication in the expander/switch is initialized and firmware updating instruction is sent to the expander/switch by the BMC. The firmware data packets are sent to the expander/switch by the BMC. A serial instruction to reset is sent to the expander/switch by the BMC and the BMC ends a communication with the UART serial. A firmware updating system applying the method is also provided.
