Configuring CoreSight systems6.1 About CoreSight system configurationCoreSight systems consist of a Debug Access Port (DAP) that comprises the followingcomponents:• A debug port (DP) that connects to the scan chain or Serial Wire Debug (SWD) interface,and that provides the system interface to debug hardware.• Either Advanced High-performance Bus Access Port (AHB-AP for AHB access) or ARMPeripheral Bus Access Port (APB-AP for APB access).Debug components are attached to the buses, and are accessed through the APs on the DAP.CoreSight debug components are configured with the index of the AP to which they areattached, and the base address on the bus.The DAP can also contain a JTAG-AP that enables the connection of JTAG devices on internalscan chains, for example ARM11 processors. JTAG devices must be configured with the APindex of the JTAG-AP, the JTAG port on the AP, and the pre-bits and post-bits for both IR andDR scans for the particular device.CoreSight components are associated with a DAP, so they are placed on the scan chain (or SWDconnection) after the DAP with which they are associated. The DAP is represented on the scanchain by the ARMCS-DP device. CoreSight components are not located on the JTAG scanchain, so they must be placed between the DAP and the next JTAG device.6.1.1 See alsoTasks• Starting the debug hardware configuration utilities on page 2-3• Setting up a CoreSight trace association file on page 6-11.Concepts• Reading the CoreSight ROM table on page 6-3• CoreSight autodetection on page 6-4• How the debug hardware unit autodetects Serial Wire Debug on page 6-5.ARM DUI 0498F Copyright © 2010-2012 ARM.
