+title: Linksys Northstar partitioning
|
|
+
|
|
+description: |
|
|
+ Linksys devices based on Broadcom Northstar architecture often use two
|
|
+ firmware partitions. One is used for regular booting, the other is treated as
|
|
+ fallback.
|
|
+
|
|
+ This binding allows defining all fixed partitions and marking those containing
|
|
+ firmware. System can use that information e.g. for booting or flashing
|
|
+ purposes.
