    Hi Steven,

    Yes, the theoretical limit is 1 metdata + 1 full image (128kB at max).
    Since each metadata is given a 1page of ext flash it would be 1*EFL_PAGE_SIZE + MAX_IMAGE_SIZE.

    You could potentially even remove the metadata page, since you only have one image, but that would require signification modification of TI SW and is not recommended.
