Given a target-files zipfile, produces an OTA package that installs
|
|
that build. An incremental OTA is produced if -i is given, otherwise
|
|
a full OTA is produced.
|
|
|
|
Usage: ota_from_target_files [flags] input_target_files output_ota_package
|
|
|
|
-b (--board_config) <file>
|
|
Specifies a BoardConfig.mk file containing image max sizes
|
|
against which the generated image files are checked.
|
|
|
|
-k (--package_key) <key>
|
|
Key to use to sign the package (default is
|
|
"build/target/product/security/testkey").
|
|
|
|
-i (--incremental_from) <file>
|
|
Generate an incremental OTA using the given target-files zip as
|
|
the starting build.
|
|
|
|
-w (--wipe_user_data)
|
|
Generate an OTA package that will wipe the user data partition
|
|
when installed.
|
|
|
|
-n (--no_prereq)
|
|
Omit the timestamp prereq check normally included at the top of
|
|
the build scripts (used for developer OTA packages which
|
|
legitimately need to go back and forth).
