Described in EMV 4.x Book 2, Chapter "Master Key Derivation", there's 3 methods to Generate MK.
And in the code of OpenEMV applet, the MK is a constant bytes, and it can be personalized before use it.

Yes you are correct. I figured it out later... after gone through some documents.
Still thanks for replying the Question and being active on this forum.
