SYStem.CONFIG.CORE Assign core to TRACE32 instance
Default core_index : depends on the CPU, usually 1. for generic chips
Default chip_index : derived from CORE= parameter of the configuration file (config.t32). The CORE
parameter is defined according to the start order of the GUI in T32Start with ascending values.
To provide proper interaction between different parts of the debugger, the systems topology must be
mapped to the debugger’s topology model. The debugger model abstracts chips and sub cores of these
chips. Every GUI must be connect to one unused core entry in the debugger topology model. Once the
SYStem.CPU is selected, a generic chip or non-generic chip is created at the default chip_index.
Non-generic Chips
Non-generic chips have a fixed number of sub cores, each with a fixed CPU type.
Initially, all GUIs are configured with different chip_index values. Therefore, you have to assign the
core_index and the chip_index for every core. Usually, the debugger does not need further information to
access cores in non-generic chips, once the setup is correct.
Generic Chips
Generic chips can accommodate an arbitrary amount of sub-cores. The debugger still needs information
how to connect to the individual cores e.g. by setting the JTAG chain coordinates.
Start-up Process
The debug system must not have an invalid state where a GUI is connected to a wrong core type of a non-
generic chip, two GUIs are connected to the same coordinate or a GUI is not connected to a core. The initial
state of the system is valid since every new GUI uses a new
chip_index according to its CORE= parameter
of the configuration file (config.t32). If the system contains fewer chips than initially assumed, the chips must
be merged by calling
SYStem.CONFIG.CORE .
