Dear All,
The CSEs is enabled,master key is setting, now i want to restore factory Settings with CSEc,but "CSEC_DRV_DbgChal" reply failed,failed return value is "STATUS_SEC_KEY_WRITE_PROTECTED",
May I ask what caused the failure?
Hello @wang_q4,
The keys must not be configured as write-protected, otherwise they can't be erased, unfortunately,
