ARM Cortex-A53 Deadlock During DSB SY Execution: Debugging and Solutions
Cortex-A53 Deadlock Manifestation and DSB SY Command Correlation The Cortex-A53 processor, part of the ARMv8-A architecture, is widely used in embedded systems for its balance of performance and power efficiency. However, under certain conditions, the processor can enter a deadlock state, particularly when executing the Data Synchronization Barrier (DSB SY) instruction. This deadlock manifests as…
