Secure boot K32L3A (FRDM-K32L3A6)

[Lloyd77]

Hello,

I'm seeking a tutorial / instructions on how to implement secure boot on the K32L3A.  I'm using the FRDM-K32L3A6 board with MCUXpresso.

How can I create the signed FW image and load it onto the target?  How can I configure target so that it checks signature, etc. 

Thanks,
