M32R Debugger and Trace 6 Q u i c k S t a r t

Quick Start

Starting up the debugger is done as follows:

Select the device prompt for the ICD Debugger and reset the system.

The device prompt B:: is normally already selected in the command line. If this is not the case enter B:: to

set the correct device prompt. The RESet command is only necessary if you do not start directly after

booting the TRACE32 development tool.

1. Specify the CPU specific settings.

The default values of all other option are set in such a way that it should be possible to work without

modification. Please consider that this is probably not the best configuration for your target.

2. Set up data for electrical interface.

Normally the default value is 10.0 MHz, but the it can be increased up to 25 MHz.

3. Inform the debugger about read only and none-readable address ranges (ROM, FLASH).

The BreakOnchip information is necessary to decide where on-chip breakpoints must be used. On-

chip breakpoints are necessary to set program breakpoints to FLASH/ROM. The sections of FLASH

and ROM depend on the specific CPU and its chip selects. Accesses to invalid addresses can cause

unrecoverable bus errors. To avoid bus errors from the debugger side use the subcommands of MAP

to define inaccessible memory areas. Bus errors can be removed by executing SYStem.Up. Make

sure that there isn’t any T32 window open which accesses to a inaccessible memory that is not

masked out, otherwise the bus error can occur again.
