HABv4 - Is it possible to sign and check only a part of an image?

[mklug_xx]

The background of this question is as follows:

For some reasons we have a very large image (which we can't split).

Checking the whole image during secure boot would take too long.

Because CSF configuration contains start and end address, is it possible to sign and check only a part of the image?

Hello,

  yes, it is possible to have signed only a part of an image.

The rest of the image can be checked later if needed.

Have a great day,
Yuri
