Fastboot Support

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

Quirk use

This plugin uses the following plugin-specific quirk:

Quirk	Description	Minimum fwupd version
`FastbootBlockSize`	Block size to use for transfers	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.
