``debugpoint`` Debug Utility
|
|
=====================================
|
|
|
|
``CONFIG_SYSTEM_DEBUGPOINT=y``
|
|
|
|
The ``debugpoint`` utility is a tool for testing and managing debug points (breakpoints and watchpoints) in the system. It allows users to set, remove, and test various types of debug points.
|
|
|
|
Usage::
|
|
|
|
debugpoint [options]
|
|
|
|
Options::
|
|
|
|
-r addr Set a read watchpoint at address
|
|
-w addr Set a write watchpoint at address
|
|
-b addr Set a breakpoint at address
|
|
-x addr Set a read/write watchpoint at address
|
|
-c Cancel the watchpoint or breakpoint (must be used with -r, -w, -b, or -x)
|
|
-l len Set the watch length (must be used with -r, -w, -b, or -x)
|
|
|
|
Examples::
|
|
|
|
# Set a read watchpoint at address 0x1000
|
|
debugpoint -r 0x1000
|
|
|
|
# Set a write watchpoint at address 0x2000
|
|
debugpoint -w 0x2000
|
|
|
|
# Set a breakpoint at address 0x3000
|
|
debugpoint -b 0x3000
|
|
|
|
# Set a read/write watchpoint at address 0x4000
|
|
debugpoint -x 0x4000
|
|
|
|
# Cancel the read watchpoint at address 0x1000
|
|
debugpoint -r 0x1000 -c
|
|
|
|
# Cancel the write watchpoint at address 0x2000
|
|
debugpoint -w 0x2000 -c
|
|
|
|
# Cancel the breakpoint at address 0x3000
|
|
debugpoint -b 0x3000 -c
|
|
|
|
# Cancel the read/write watchpoint at address 0x4000
|
|
debugpoint -x 0x4000 -c
|
|
|
|
# Set the watch length to 8 bytes for a read watchpoint at address 0x1000
|
|
debugpoint -r 0x1000 -l 8
|
|
|
|
# Set the watch length to 8 bytes for a write watchpoint at address 0x2000
|
|
debugpoint -w 0x2000 -l 8
|
|
|
|
# Set the watch length to 8 bytes for a breakpoint at address 0x3000
|
|
debugpoint -b 0x3000 -l 8
|
|
|
|
The ``debug`` utility also includes automated tests for breakpoints and watchpoints. When run without any options, it will execute these tests to verify the functionality of the debug points.
