CC_ARMSS: Powering Down CC_ARMSS1 Causes System Data Corruption
When attempting to power down CC_ARMSS1, programming sequences defined in Power Modes Section of ID062414 are followed as:
During the execution of these sequences, data corruption can be observed in the rest of the device subsystems, causing device, operating system(s), and application software to hang or malfunction.
Cluster power down shall not be used. Instead, system may program individual cores to be shut down, by following the programing sequence defined in Power Modes Section of ID062414, but leave the CC_ARMSS1 cluster power domain ON.
