Introduction

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
  • CUSTOM section only
  • Multiple sections excluded CUSTOM — at fixed offsets and sizes

This plugin supports the following protocol ID:

  • com.analogix.bb

GUID Generation

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

  • USB\VID_1F29&PID_7518
  • USB\VID_050D&PID_008B
  • USB\VID_047D&PID_80C8
  • USB\VID_0502&PID_04C4
  • USB\VID_14B0&PID_01D0
  • USB\VID_14B0&PID_01D1

Update Behavior

The device is updated at runtime using USB control transfers.
