Abstract: A system for updating firmware through a DisplayPort interface includes a source device with a DisplayPort interface, and a sink device with a DisplayPort interface. The source device includes a storage circuit for storing and providing an updated firmware, and a source device auxiliary channel for outputting the updated firmware with an auxiliary channel signal format. The sink device includes a sink device auxiliary channel for receiving the updated firmware with the auxiliary channel signal format and thereby generating an output signal, an I2C auxiliary channel device servicer for receiving the output signal and generating an I2C protocol updated firmware, and a memory unit for updating firmware according to the I2C protocol updated firmware. A method for updating firmware is also disclosed.
