Attempting to set a software breakpoint; error messages appear.1010232

Latest Updated:10/02/2012

Question:

Debugging is being performed in the High-performance Embedded Workshop (HEW) environment using the E1/E20 emulator.

When attempting to set a software breakpoint, the following error message is displayed.

When using the E1/E20 emulator debugger for RX family:
No software break points can be set in the on-chip ROM area during debugging CPU re-write mode.

When using the E1/E20 emulator debugger for R8C family:
The command is not executable during debugging with the flash ROM being programmed.

Answer:

When a program that rewrites contents in the on-chip flash ROM area is specified to be debugged (*), no software breakpoint can be set.

When debugging a program that rewrites contents in the on-chip flash ROM area, use an on-chip break.

When a program that rewrites contents in the on-chip flash ROM area is not debugged, cancelling the following setting allows software breakpoints to be used.

* Select [Debugging the program re-writing the internal PROGRAM ROM] (Note) in the [System] tab of the [Configuration Properties] dialog box that is displayed when the emulator is started up.

Note: For the E1/E20 R8C emulator debugger, select [Debugging the program re-writing the internal flash].
