Lora AppKey Auto generate

[NAndreadakis]

Hello,

I'm trying to auto generate the the AppKey on device boot using the KMS Derive.

I have enabled the LORAWAN_KMS definition as described on the AN5406 and also the configuration that needed. But the device don't generate any key and after investigation the C_DeriveKey() throwing error CKR_DEVICE_MEMORY that cant find a solution yet. Is any better way to auto generate the key without flashing any blob?
