3.7 Debugging Environment

The debugger supports two connect modes, of which the mode used is set by the target command.
iCD Mini mode
In this mode, the ICD Mini (S5U1C17001H) or ICD board is used to perform debugging. The program is ex-
ecuted on the target board.
Specification method
Command: (gdb) target icd usb
Specification in IDE:
Select "ICD Mini" from the [Debugger:] combo box in the [Create a simple startup command] dia-
log box to generate a startup command file.
To start in ICD Mini mode, make sure an ICD and target board are connected correctly, and that the power for
these units is turned on. For details on how to use the ICD, refer to the manual for the ICD used.
Note that the trace function is not available in ICD Mini mode.
Simulator (SiM) mode
In simulator mode, target program execution is simulated in internal memory of a personal computer, with no
other tools required. However, the ICD-dependent functions cannot be used in this mode.
Specification method
Command: (gdb) target sim
Specification in IDE:
Select "Simulator" from the [Debugger:] combo box in the [Create a simple startup command] dia-
log box to generate a startup command file.
The trace function is available in simulator mode. The flash writer function cannot be used.
