Abstract (en)
[origin: WO2021019270A1] Apparatus and method (200) for updating firmware in a chipset having a chipset microcontroller and a chipset memory. The chipset microcontroller is placed in an inactive state (208), such as during a boot reinitialization sequence. A host microcontroller writes a firmware image, representing updated firmware for the 5 chipset microcontroller, directly to the chipset memory (210) using an SPI (Serial Peripheral Interface) connection. The host microcontroller reads back the transferred firmware image from the chipset memory to verify a successful transfer of the firmware image (212). The chipset microcontroller is subsequently transitioned to an active state to execute the transferred firmware image (214). The chipset may form a 10 controller of a computer peripheral device, such as a data storage device. The firmware image may be supplied to the chipset memory using an HID (Human Interface Device).
