===================================== ``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.
