From: Lukas Funke <lukas.fu...@weidmueller.com> Adds features to explicitly write zeros to the start of the partition. This is useful to overwrite old content like filesystem signatures which may be re-recognized otherwise.
The new features can be enabled with '--soucreparams="[fill|size=<N>[S|s|K|k|M|G]][,][bs=<N>[S|s|K|k|M|G]]"' Conflicting or missing options throw errors. The features are: - fill Fill the entire partition with zeros. Requires '--fixed-size' option to be set. - size=<N>[S|s|K|k|M|G] Set the first N bytes of the partition to zero. Default unit is 'K'. - bs=<N>[S|s|K|k|M|G] Write at most N bytes at a time during source file creation. Defaults to '1M'. Default unit is 'K'. Changes in v3: - Add testcase - Fix interpretation of --fixed-size parameter Changed in v2: - Added SoB --- Lukas Funke (1): selftest: wic: add test for zerorize option of empty plugin Malte Schmidt (1): wic: extend empty plugin with options to write zeros to partiton meta/lib/oeqa/selftest/cases/wic.py | 36 ++++++++++++++++ scripts/lib/wic/plugins/source/empty.py | 57 ++++++++++++++++++++++++- 2 files changed, 92 insertions(+), 1 deletion(-) -- 2.30.2
