Multi-core debugging

J-Link / J-Trace is able to debug multiple cores on one target system connected to the same
scan chain. Configuring and using this feature is described in this section.
5.6.1

How multi-core debugging works

Multi-core debugging requires multiple debuggers or multiple instances of the same debug-
ger. Two or more debuggers can use the same J-Link / J-Trace simultaneously. Configuring
a debugger to work with a core in a multi-core environment does not require special set-
tings. All that is required is proper setup of the scan chain for each debugger. This enables
J-Link / J-Trace to debug more than one core on a target at the same time. The following
figure shows a host, debugging two CPU cores with two instances of the same debugger.
Both debuggers share the same physical connection. The core to debug is selected through
the JTAG-settings as described below.
