Hi,

I am trying to debug the application running on arm based target,
gdb,OpenOCD.

I am using watch points to debug the application.

In debug mode, the below RSP communication shows that the address for the
packets m, Z2 and Z0 shows wrong. Is it so ?
If yes, what can be the wrong ? Any hint to debug either at gdb side or
OpenOCD side ?

Is there any possibility of addresses can become single degit like this ?

Breakpoint 1, main () at test.c:13
