Sets or clears the target breakpoint

Syntax

bkpt - S tid addr
bkpt - C tid bpid

Description

bkpt

This command sends a request to set or clear a breakpoint in the target system by way of the dbgif tool.

tid

The tid is the thread number. Even though a breakpoint is not thread-specific in this debugger, you must still specify a thread.

addr

The addr is the address at which a breakpoint should be set.

bpid

The bpid argument is the number of the breakpoint to be cleared.

Before executing this command, you must ensure that the dbgif program is running and that the METHOD environment variable is set to indicate whether this is a request for the R4300 CPU or the RCP co-processor.

The value zero represents the CPU and the value one represents the RCP. In csh, this is accomplished by specifying the following.

setenv METHOD 0 

Note

In the event of a communications failure, the program will dump the core file. If this happens, you will need to remove the core file manually.

Note that support for the -l option to list breakpoints is not implemented in this version of the debug monitor.
