Expand description

Takes the given file_to_upload for the named partition and creates a set of SparseFileWriter slices in memory with the provided max_download_size constraining slice size.

§Arguments

  • name - Name of the partition for the image. Used for logs only.
  • file_to_upload - Path to the file to translate to sparse image format.
  • max_download_size - Maximum size that can be downloaded by the device for each slice.
