The Coresight nodes are enabled by default for commercial devices(fused), but only part of functions can run with commercial devices because it needs check fuse data before running. > > If we want enable all debug functions related to coresight nodes on commercial devices, we need APDP override(APPS debug policy override) procedure first. The APDP override procedure will override some fuse data to allow debug sessions. In other words, will a production fused device boot with this patch applied? Konrad
