Select this option to use a custom ubinize configuration file,
|
||
|
|
rather than the default configuration used by Buildroot (which
|
||
|
|
defines a single dynamic volume marked as auto-resize). Passing
|
||
|
|
a custom ubinize configuration file allows you to create several
|
||
|
|
volumes, specify volume types, etc.
|
||
|
|
|
||
|
|
As a convenience, buildroot replaces the string
|
||
|
|
"BR2_ROOTFS_UBIFS_PATH" with the path to the built ubifs file.
|
||
|
|
So the volume defined for the root filesystem can specify the
|
||
|
|
image path as: image=BR2_ROOTFS_UBIFS_PATH
