# Analogix
|
|
|
|
## 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`
|
|
|
|
## Update Behavior
|
|
|
|
The device is updated at runtime using USB control transfers.
|
|
|
|
## Vendor ID Security
|
|
|
|
The vendor ID is set from the USB vendor. The list of USB VIDs used is:
|
|
|
|
* `USB:0x1F29`
|
|
* `USB:0x050D`
|
|
* `USB:0x047D`
|
|
* `USB:0x0502`
|
|
|
|
## External Interface Access
|
|
|
|
This plugin requires read/write access to `/dev/bus/usb`.
