cosiCompression type

Specifies the zstd compression settings for the partition images within the COSI output image.

If not specified, the default compression level is used.

Example:

output:
  image:
    path: ./out/image.cosi
    format: cosi
    cosi:
      compression:
        level: 22

level [int]

Optional. Default: 9

If both output.image.cosi.compression.level and --cosi-compression-level are provided, then the --cosi-compression-level value is used.

The zstd compression level (1-22) for COSI partition images.

Higher compression levels produce smaller files but take significantly longer to compress. Decompression speed is largely unaffected by the compression level.

Added in v1.2.
