title: Fixed partitions
|
|
|
|
description: |
|
|
This binding can be used on platforms which have strong conventions about
|
|
which portions of a flash are used for what purposes, but which don't use an
|
|
on-flash partition table such as RedBoot.
|
|
|
|
The partition table should be a node named "partitions". Partitions are then
|
|
defined as subnodes.
