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.
