Fastboot

Introduction

This plugin is used to update hardware that uses the fastboot protocol.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in ZIP file format. Inside the zip file must be all the firmware images for each partition and a manifest file. The partition images can be in any format, but the manifest must be either an Android flashfile.xml format file, or a QFIL partition_nand.xml format file.

For both types, all partitions with a defined image found in the zip file will be updated.

This plugin supports the following protocol ID:

  • com.google.fastboot

GUID Generation

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

  • USB\VID_18D1&PID_4EE0&REV_0001
  • USB\VID_18D1&PID_4EE0
  • USB\VID_18D1

Update Behavior

A fastboot device usually presents in runtime mode (or with no interface), but if the user puts the device into fastboot mode using a physical button it then enumerates with a USB descriptor. On attach the device reboots to runtime mode which may mean the device "goes away".

For this reason the REPLUG_MATCH_GUID internal device flag is used so that the bootloader and runtime modes are treated as the same device.

Quirk Use

This plugin uses the following plugin-specific quirk:

FastbootBlockSize

Block size to use for transfers.

Since: 1.2.2

Vendor ID Security

The vendor ID is set from the USB vendor, for example USB:0x18D1

External Interface Access

This plugin requires read/write access to /dev/bus/usb.
