Plugin: Analogix


This plugin can flash the firmware of some Analogix billboard devices.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in a Intel Hex file format. The resulting binary image is either:

  • OCM section only

  • Multiple sections excluded CUSTOM — at fixed offsets and sizes

This plugin supports the following protocol ID:


GUID Generation

These devices use the standard USB DeviceInstanceId values, e.g.

  • USB\VID_1F29&PID_7518

  • USB\VID_0502&PID_04C4
