3. Arm* Cortex*-A53 MPCore* and CoreSight* Errata

This section lists the Arm* Cortex-A53 MPCore* and CoreSight* errata.
Note: This errata only applies if you are using devices which are enabled with the Hard Processor System (HPS).
Each listed erratum has an associated category number which identifies the degree of the behavior.

The categories are as follows:

  • Category 1: Behavior has no workaround and severely restricts the use of the product in all, or the majority of applications, rendering the device unusable.
  • Category 2: Behavior contravenes the specified behavior and might limit or severely impair the intended use of the specified features, but does not render the product unusable in all or the majority of applications.
  • Category 3: Behavior that was not the originally intended behavior but should not cause any problems in applications.
Note: This device only contains category 2 and category 3 errata.
