# MTD
|
|
|
|
## Introduction
|
|
|
|
The Memory Technology Device (MTD) interface is a way of abstracting flash devices as if they were
|
|
normal block devices.
|
|
|
|
See <http://www.linux-mtd.infradead.org/doc/general.html> for more details.
|
|
|
|
This plugin supports the following protocol ID:
|
|
|
|
* org.infradead.mtd
|
|
|
|
## GUID Generation
|
|
|
|
These devices use custom DeviceInstanceId values built from the device `NAME` and DMI data, e.g.
|
|
|
|
* `MTD\NAME_Factory`
|
|
* `MTD\VENDOR_foo&NAME_baz`
|
|
* `MTD\VENDOR_foo&PRODUCT_bar&NAME_baz`
|
|
|
|
If the `FirmwareGType` quirk is set for the device then the firmware is read back from the device at
|
|
daemon startup and parsed for the version number.
|
|
In the event the firmware has multiple child images then the device GUIDs are used as firmware IDs.
|
|
|
|
## Update Behavior
|
|
|
|
The MTD device is erased in chunks, written and then read back to verify.
|
|
|
|
## Vendor ID Security
|
|
|
|
The vendor ID is set from the system vendor, for example `DMI:LENOVO`
|
|
|
|
## External Interface Access
|
|
|
|
This plugin requires read/write access to `/dev/mtd`.
