Hello,


The recurring message svc_normal_to_secure_thread: STATUS_ERROR suggests a failure in secure-world communication between the ARM Trusted Firmware (ATF) and the hardware.


The bl31.bin may not include the necessary support for Secure Mailbox services, which are essential for commands like COMMAND_FCS_RANDOM_NUMBER_GEN.


Check if your ATF configuration (plat/arm/board/stratix10/) includes secure mailbox support and the appropriate platform-specific definitions.


regards,

Farabi
