[MPC5746C][HSM] Regarding generating new BOOT_MAC

Dear Sir,

I implemented the code that generate new BOOT_MAC by referring to section "2.10.3. Method 1: Use the LOAD_RAM_KEY command and HSM to generate the new BOOT_MAC" in AN5178, and then updated the BOOT_MAC memory slot, key id is 3, by using memory update protocol.

I could see there are two old and new key blocks have same key id on HSM Key area like the bellow.

I think the old slot should be updated and this symptom is incorrect.

Could you please confirm whether this symptom is incorrect or not?

Thanks and regards,

Namwook
