After trying to use watch command, LLDB said the device had 0 available hardware watchpoints. In GDB you can use

set can-use-hw-watchpoints 0

How do you disable hardware watchpoints in LLDB?

As we know there are limitations to using watchpoints: there are a finite amount of watchpoints permitted per architecture (typically 4) and the “watched” size of memory usually caps out at 8 bytes. Therefore, it is important to delete them after they are no longer needed.

You can delete a watchpoint in lldb using the watchpoint delete command and passing the watchpoint ID as an argument.

Example:

(lldb) watchpoint delete 1
1 watchpoints deleted.

Or we can use,

(lldb) w delete 1
1 watchpoints deleted.

To delete all watchpoints - simply omit the last argument.

  • @Silent LLDB doesn't have software watchpoint. Make sure your watchpoint expression size is less or equal to hardware watchpoint size that your machine can handle. Jun 12 at 18:17
  • I guess this is a definite answer. Thanks
