Deny By Default
Enforcing enhanced security in the default state of the SoC out of reset, the Resource Domain Controller(RDCs) are deployed in i.MX 8ULP A1 SoC to implement a deny-by-default (DBD) architecture so that all accesses are denied unless specifically configured to allow access. Once the SoC boots up, the Apps cores can request EdgeLock Secure Enclave to release access of RDCs to respective cores for further configuration.
More information on this feature is attached.
