Common options that apply to both of non-A/B and A/B OTAs

--downgrade
|
||||
Intentionally generate an incremental OTA that updates from a newer build
|
||||
to an older one (based on timestamp comparison). "post-timestamp" will be
|
||||
replaced by "ota-downgrade=yes" in the metadata file. A data wipe will
|
||||
always be enforced, so "ota-wipe=yes" will also be included in the
|
||||
metadata file. The update-binary in the source build will be used in the
|
||||
OTA package, unless --binary flag is specified. Please also check the doc
|
||||
for --override_timestamp below.
|
||||
|
||||
-i (--incremental_from) <file>
|
||||
Generate an incremental OTA using the given target-files zip as the
|
||||
starting build.
|

|
||||
-k (--package_key) <key>
|
||||
Key to use to sign the package (default is the value of
|
||||
default_system_dev_certificate from the input target-files's
|
||||
META/misc_info.txt, or "build/target/product/security/testkey" if that
|
||||
value is not specified).
|
||||
|
||||
For incremental OTAs, the default value is based on the source
|
||||
target-file, not the target build.
|
||||
|
||||
-i (--incremental_from) <file>
|
||||
Generate an incremental OTA using the given target-files zip as
|
||||
the starting build.
|
||||
--override_timestamp
|
||||
Intentionally generate an incremental OTA that updates from a newer build
|
||||
to an older one (based on timestamp comparison), by overriding the
|
||||
timestamp in package metadata. This differs from --downgrade flag: we know
|
||||
for sure this is NOT an actual downgrade case, but two builds are cut in a
|
||||
reverse order. A legit use case is that we cut a new build C (after having
|
||||
A and B), but want to enfore an update path of A -> C -> B. Specifying
|
||||
--downgrade may not help since that would enforce a data wipe for C -> B
|
||||
update. The value of "post-timestamp" will be set to the newer timestamp
|
||||
plus one, so that the package can be pushed and applied.
|
||||
|
||||
--full_radio
|
||||
When generating an incremental OTA, always include a full copy of
|
||||
radio image. This option is only meaningful when -i is specified,
|
||||
because a full radio is always included in a full OTA if applicable.
|
||||
--wipe_user_data
|
||||
Generate an OTA package that will wipe the user data partition when
|
||||
installed.
|
||||
|
||||
Non-A/B OTA specific options
|
||||
|
||||
-b (--binary) <file>
|
||||
Use the given binary as the update-binary in the output package, instead
|
||||
of the binary in the build's target_files. Use for development only.
|
||||
|
||||
--block
|
||||
Generate a block-based OTA for non-A/B device. We have deprecated the
|
||||
support for file-based OTA since O. Block-based OTA will be used by
|
||||
default for all non-A/B devices. Keeping this flag here to not break
|
||||
existing callers.
|
||||
|
||||
-e (--extra_script) <file>
|
||||
Insert the contents of file at the end of the update script.
|
||||
|
||||
--full_bootloader
|
||||
Similar to --full_radio. When generating an incremental OTA, always
|
||||
include a full copy of bootloader image.
|
||||
|
||||
--verify
|
||||
Remount and verify the checksums of the files written to the system and
|
||||
vendor (if used) partitions. Non-A/B incremental OTAs only.
|
||||
--full_radio
|
||||
When generating an incremental OTA, always include a full copy of radio

image. This option is only meaningful when -i is specified, because a full

-o (--oem_settings) <main_file[,additional_files...]>

--log_diff <file>
|
||||
Generate a log file that shows the differences in the source and target
|
||||
builds for an incremental package. This option is only meaningful when -i
|
||||
is specified.

-o (--oem_settings) <main_file[,additional_files...]>
