I've created a "first boot" routine to initialize the CSEc module on our S32K, but I'd like a way for that routine to see if key slots are currently loaded or not.
Is there a recommended way to do that, like reading a register?
The only way I can think of based on the documentation is to compute key parameters for a blank key to see if it matches the M4/ M5 from the CSEc module when I try to load a blank key
