Follow these steps to recover from an internal error:
- Read the error log on the AXI-Lite interface by reading the ferr_log and interr_log registers.
- Understand and correct the cause of the error.
- Assert the subsystem_cold_rst_n reset. The signal assertion resets both, the Symmetric Cryptographic Accelerator Hard IP and AES/SM4 Inline Cryptographic Accelerator since these errors are not recoverable.
