In some aspects, the present disclosure provides a method of cali- brating 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 extemal 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.
