SiS Firmware Updater


The code was proviced by SiS and modified by Google. Modifications include:

  • Cleaning the code according to Google C++ coding style. Eliminating compiling errors.
  • Adding a feature that the updater can take the device name from input parameters. Blinded search is only required when input device name is invalid.
  • Adding a feature that the updater will compare FW version before actual update. If the FW versions on device and in Chrome OS are same, the updater will terminate.
  • Adding a input flag specifying whether the device is in recovery mode (FW update fails last time). The flag value is determined by VID from udev rule.


On Linux, should run as root.
