Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method of calibrating a component. The method includes receiving previous calibration parameters for an external component at a secondary SoC from a primary SoC, wherein the secondary SoC is coupled to the external component and configured to calibrate the external component. The method further includes determining validity of the previous calibration parameters by the secondary SoC. The method further includes operating the external component by the secondary SoC based on the determined validity of the previous calibration parameters.

Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method of authenticating executable images in a system-on-chip (SoC), the method comprising: storing a plurality of executable images; storing, as separate from the plurality of executable images, a signed image of hashes comprising a plurality of hashes corresponding to the plurality of executable images and a first signature; authenticating the signed image of hashes based on the first signature; and using a first hash of the plurality of hashes to authenticate a first executable image of the plurality of executable images when the signed image of hashes passes authentication.
