config BR2_TARGET_ROOTFS_UBI
bool "ubi image containing an ubifs root filesystem"
select BR2_TARGET_ROOTFS_UBIFS
help
Build an ubi image from the ubifs one (with ubinize).
if BR2_TARGET_ROOTFS_UBI
config BR2_TARGET_ROOTFS_UBI_PEBSIZE
hex "physical eraseblock size"
default 0x20000
help
Tells ubinize the physical eraseblock (PEB) size of the
flash chip the ubi image is created for. The value provided
here is passed to the -p/--peb-size option of ubinize.
config BR2_TARGET_ROOTFS_UBI_SUBSIZE
int "sub-page size"
default 512
help
Tells ubinize that the flash supports sub-pages and the
sub-page size. Use 0 if sub-pages are not supported on flash
chip.
The value provided here is passed to the -s/--sub-page-size
option of ubinize.
config BR2_TARGET_ROOTFS_UBI_USE_CUSTOM_CONFIG
bool "Use custom config file"
help
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
config BR2_TARGET_ROOTFS_UBI_CUSTOM_CONFIG_FILE
string "Configuration file path"
depends on BR2_TARGET_ROOTFS_UBI_USE_CUSTOM_CONFIG
help
Path to the ubinize configuration file.
config BR2_TARGET_ROOTFS_UBI_OPTS
string "Additional ubinize options"
help
Any additional ubinize options you may want to include.
