CoreSight Access Tool (CSAT)
The CoreSight
™
Access Tool (CSAT) provides a scriptable low-level interface to the CoreSight
Debug Access Port (DAP) on a target. CSAT is useful to perform initial bring-up tests before a
debugger connection to the target is available.

. In your Arm
Development Studio installation, CSAT is located in
<install_directory>/Arm/
Development Studio <version>/bin/csat.exe

4.2 Hot-plug the debug cable
At times, you might want to connect or disconnect the debug cable between the DSTREAM-XT
system and the target hardware, without powering off the target. This process is known as
hot-
plugging
.
Arm recommends you avoid hot-plugging the debug cable. However, you can hot-plug without
affecting target operation, if:
• The DSTREAM-XT system is powered by its original power supply (which has an earthed-
output).
• The target hardware is earthed, either through its power supply, or a separate earth connection.
• If the DSTREAM-XT system or the target hardware are not properly earthed,
potential differences can occur between them. During connection, potential
differences can cause unwanted pulses in the debug interface. Pulses in the
debug interface can cause unwanted resets to occur.
• Hot-plugging of a PCIe interface is not recommended and could cause instability
in a target's operating system.
Hot-plugging: connecting
To connect a DSTREAM-XT system to a target without affecting its current state, you must:
1. Power up the DSTREAM-XT system. Allow the DSTREAM-ST and XT probe to boot up.
