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.

Oh so lldb does not have support for software watchpoints unlike gdb? Its after a reboot and its only one watchpoint i have added.– SilentCommented Jun 12, 2022 at 17:33

@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.– ViktorCommented Jun 12, 2022 at 18:17
